What is the difference between red bricks and green bricks, and the difference between green bricks

For many friends, when decorating, they think that floor tiles and wall tiles are the same and can be used together, but in fact, this is very unsafe and not very scientific. So, what is the difference between floor tiles and wall tiles? What are the precautions for laying wall tiles and floor tiles?

Let's introduce the difference between floor tiles and wall tiles, as well as the precautions when laying, I hope it will be helpful to you.

1. The difference between floor tiles and wall tiles.

1. The water absorption rate of floor tiles and wall tiles is different.

Strictly speaking, wall tiles belong to pottery, while floor tiles belong to porcelain products, their essence and physical properties are different, whether it is from the selection of clay ingredients or to the firing process are very different. Generally, the water absorption rate of wall tiles is about 10%, which is several times higher than that of floor tiles with a water absorption rate of only 1%.

2. The place of use is different.

Generally, floor tiles are laid on the floor of bathrooms and kitchens, because of its low water absorption, so that bathrooms and kitchens will not be affected by water vapor and are less likely to absorb stains. The wall tiles are made of glazed pottery, with high moisture content, so its back is usually rough, so it is conducive to pasting the wall tiles with adhesives, and the floor tiles are not firmly pasted on the wall, and the wall tiles are used on the ground because they absorb more water and become difficult to clean, so the two can not be mixed.

3. Pay attention to the laying sequence.

Because the floor tiles are pasted from the inside out, if the ground has a slope or a floor drain, attention should be paid to arranging the water direction to find the slope; The wall tiles are paved from the bottom up, and for aesthetic reasons, the bottom bricks should be pasted last.

Second, the precautions for laying wall tiles and floor tiles.

1. Before preparing to paste tiles, the base should be cleaned up at the grassroots level, such as lime plaster, latex paint, wallpaper and other decorations on the wall, or dirt on the ground, etc., which must be cleaned up, otherwise the cement mortar will not be firmly bonded with the base layer; If there are cracks in the wall itself, it should be properly treated before tiling.

2. After the wall tiles are pasted, the floor tiles should be pressed again, and if there is a situation where half a brick appears, it should be placed at the bottom as much as possible. In addition, when pasting wall tiles, one wall can not be pasted to the top at one time, so that the tiles are prone to collapse.

3. Because the wall tiles have a relatively high moisture content, this characteristic must be taken into account when pasting, and the base layer should be fully watered and moistened before pasting, and the tiles should be soaked in water for at least 20 minutes before they can be used.

The difference is that the processing raw materials of green bricks and red bricks are different:

Red bricks are made of clay, shale, gangue and other raw materials, which are crushed, mixed and kneaded, manually or mechanically pressed and formed, and then dried and placed at a temperature of about 900 degrees Celsius and fired by an oxidation flame.

Green bricks belong to sintered bricks, and the main raw material for firing ancient green bricks is clay, which is mixed with water and extruded. Then it is baked to a brick kiln to about 1,000 degrees Celsius, and then cooled with water to make the iron in the clay not completely oxidized, so that it has good weathering resistance and water resistance.

Advantages of green bricks: after the bricks are fired in an oxidizing atmosphere. Then in the reducing atmosphere of the kiln, the red ** iron oxide in the brick is reduced to blue-gray low-cost iron oxide, the green brick is stronger than the red brick, good alkali resistance, strong durability.

Advantages of red bricks: the production process is relatively simple, mechanized production can be realized, the production efficiency is high, and it is widely used.

The red bricks are burned inside and out with a large fire, and then the fire is extinguished to make the kiln and the bricks cool naturally, the air circulation in the kiln is sufficient, and a good oxidation atmosphere is formed, and the iron element of the bricks is oxidized to ferric oxide. So it's rendered red.

The difference between <> green bricks and red bricks is that the raw materials and processes for production are different, resulting in different colors and properties.

The raw materials for production are different.

Green bricks are mainly made from sludge and clay that are processed from iron in the raw materials used to produce them, so they appear dark green or dark gray. Red bricks, on the other hand, are mainly made of red clay that are made from raw materials that contain no iron, so red bricks will appear red when made at high temperatures.

The process is different. Green bricks need to go through a high-temperature firing process during the production process, which can enhance their hardness and compressive properties. Red bricks are mainly dried by natural drying processes such as sun drying and air drying, which makes them more fragile than hall rocks and suitable for building walls and masonry.

The application is different. Green bricks are suitable for buildings in high-pressure environments, such as bridges and foundations, because of their excellent hardness and compressive properties. Red bricks, on the other hand, are suitable for buildings with low pressure loads, such as houses and building walls.

Expand your knowledge:

Both green bricks and red bricks have certain applications in the construction of imperial buildings, but at the same time, the development of modern industrial technology has also appeared a new type of material - cement bricks. Compared with traditional bricks, cement bricks are not only more advanced in the production process, but also more advantageous in production costs, and can be applied to more building environments, becoming one of the most widely used brick materials in the construction field.

Green brick and red brick are two different building materials that are often used in different places and uses. The differences are as follows:

Material: Green bricks, also known as gray bricks, are made of clay and other timber materials, while red bricks are mainly made of red clay.

Color: Green bricks are dark in color, usually gray or brown. The color of red bricks is different from the kiln temperature, the burning state and the composition of the clay, showing reddish-brown, red, purple-red and other colors.

Strength: Red bricks are stronger and more durable than green bricks, and can withstand greater pressure and torque.

Use of Fan Chunziwei: Red bricks are widely used in houses, bridges and other building structures, while green bricks are mainly used in small and medium-sized buildings and interior walls, wall columns, foundations, etc.

1. Material comparison.

Red bricks: clay firing with low purity, the clay contains iron, and when it is completely oxidized during the firing process, ferric oxide is generated and red;

Green bricks: When the clay is fired, water is added to cool it during the firing process, so that the iron in the clay is not completely oxidized and turns cyan.

Second, the advantages of comparison.

Red brick: durability, certain thermal insulation, sound insulation characteristics;

Respiratory characteristics, regulating indoor and outdoor humidity;

Fireproof; Green bricks:

Extremely breathable and absorbent;

Strong density, good frost resistance, no deformation, no discoloration;

Strong plasticity. 3. Comparison of shortcomings.

Red bricks: high hardness, lack of toughness;

It is not environmentally friendly and cannot be used.

Green bricks: **high;

Difficult to match; It will lead to poor indoor lighting.

Fourth, ** comparison.

Red brick: the standard specification is 40mm*115mm*53mm, which is controlled by about the yuan;

Green bricks: **Around the yuan.

Red brick and green brick are common building materials, and they differ in material, use, and appearance.

First of all, red bricks are usually obtained by firing clay and other materials at high temperatures, so its texture is relatively hard and dense. The color of red bricks is a red color, and it is generally used to build indoor and outdoor walls, pillars and other structures. Red bricks have good thermal insulation, moisture absorption and thermal insulation properties, which are suitable for building buildings with a traditional atmosphere.

The green bricks, on the other hand, are made of a mixture of clay and lime to form a cracked oak wheel, and its surface has a gray-green glaze. Grey bricks are relatively lighter and are suitable for building floors, roads, plazas and other non-load-bearing parts. Green bricks have frost-resistant properties and anti-slip properties, and their aesthetically pleasing appearance also makes them a popular decorative material.

In general, red bricks and green bricks differ in their uses and characteristics. Red bricks are suitable for construction of parts that require load-bearing and thermal insulation, while green bricks are suitable for construction of parts that do not require load-bearing but need to be beautiful and non-slip.

There are several main differences between red bricks and green bricks:

1] The raw materials are different: red bricks are made of clay, while green bricks are made of materials such as lime and quartz sand.

2] Different colors: chaotic red bricks are red or brown-red because they contain high iron oxide; The green bricks are gray or blue-gray because of the lime.

3] Different functions: red bricks have high compressive strength due to their high material density and low water absorption, which is suitable for building load-bearing walls; On the other hand, green bricks are often used to build partition walls or non-fiber load-bearing walls because of their lighter material and higher water absorption.

4] The cost is different: due to the difference in raw materials and production processes, the cost of red bricks is generally higher than that of green bricks.

It is important to note that the difference between red bricks and green bricks is not absolute, and some areas may also have red bricks, while red bricks may also be used to build non-load-bearing walls.

<>First of all, the materials of the two are different. The red bricks are made of clay, shale and gangue, while the green bricks are made of clay. The firing temperature of the two is different.

The differences between green bricks and red bricks are as follows:

1.The raw materials and characteristics of the production are different. Green bricks are made of clay, which has the characteristics of good air permeability and strong water absorption, while the main raw materials used in red bricks are coal tip stones and clay, and the bricks made have the characteristics of light weight and good sound insulation.

The firing temperature is not the same. When firing green bricks, the temperature needs to be above 1000 degrees, while when firing red bricks, the temperature only needs to be above 900 degrees.2 The firing temperature is different.

When firing green bricks, the temperature needs to be above 1000 degrees, while when firing red bricks, the temperature only needs to be above 900 degrees, and the firing temperature of the two is different.

3.The cooling method is not the same. It is more troublesome to cool the green bricks, and you need to pour water into the kiln to cool them, while when cooling the red bricks, you don't need to operate too much, so that you can cool them naturally.

4. The firing process is different.

When producing bricks, the bricks are generally burned inside and out with a large fire, and then the fire is extinguished to cool the kiln and bricks naturally. Clay contains iron, and when it is completely oxidized during the firing process, it produces ferric oxide which is red, that is, the most commonly used red brick; However, if water is added to cool during the firing process, the iron in the clay is not completely oxidized and the low-valent iron is formed, which is cyan, that is, green bricks.
