What is the bulk density of ceramsite, what is the bulk density of ceramsite concrete?

The bulk density of ceramsite particles is generally 550 to 1200kg, and the loose bulk density of products is generally 300 to 1000kg.

Ceramsite has excellent properties, such as low density, high cylinder compressive strength, high porosity, high softening coefficient, good frost resistance, excellent alkali aggregate reactivity, etc. In particular, due to the small density of ceramsite, the internal porousness, the shape and composition are relatively uniform, and it has a certain strength and firmness, so it has the multi-functional characteristics of light weight, corrosion resistance, frost resistance, earthquake resistance and good insulation.

Using these excellent properties of ceramsite, it can be widely used in building materials, horticulture, food and beverage, refractory insulation materials, chemicals, petroleum and other departments, and the application field is becoming more and more extensive, and it continues to expand.

Good seismic resistance. Ceramsite concrete has good seismic performance due to its light weight, low elastic modulus and good deformation resistance. In 1976, the four ceramsite concrete slab buildings built in Tianjin were basically intact and could be used as usual.

A considerable number of brick and concrete buildings around it were damaged by the earthquake to varying degrees. Although this is related to the building structure system, the excellent seismic performance of ceramsite concrete is also an important reason.

In 1976, there was a strong level 9 in the Ferruli region of Italy, and statistics show that the damage rate of brick and concrete buildings reached 40% to 60%, the damage rate of frame structure clay hollow brick buildings was 33%, and the damage rate of ceramsite concrete buildings was only 5%. The seismic performance of ceramsite can be seen from this.

The bulk density of ceramsite is: 700-1000kg m

Bulk density is also known as severity. There are two understandings: 1. It refers to the weight of the object in the unit volume, which is often used in engineering to refer to the weight of one cubic meter, such as the weight of the soil per unit volume.

2. It represents the gravitational characteristics of an object due to the gravitational pull of the earth, and for homogeneous fluids, it refers to the gravitational force acting on a unit volume. The unit is: cattle cubic meter.

In engineering, the most commonly used is the first type.

The bulk density (density grade of ceramsite) is around 200-700kg m3.

The apparent density is around 400-1400.

Bulk density of fly ash ceramsite block: 700-900kg m3

Bulk density of ceramsite concrete: not more than 1900 kg cubic meters.

Ceramsite concrete can be divided into thermal insulation according to its use: the density is less than 800kg m; Structural insulation: density of 800 1400kg m; Structural use: the density is more than 1400kg m.

Uses: The heat resistance and fire resistance of lightweight aggregate concrete are better than those of ordinary concrete, but the elastic modulus is lower. Light aggregate concrete with ceramsite as coarse aggregate and ordinary sand or terracotta sand as fine aggregate is called ceramsite concrete.

The strength of ceramsite concrete for structure can be greater than 40MPa, and the thermal insulation and heat resistance performance are good.

Concrete curing requirements:

1. When the concrete may be in contact with the flowing water after the demoulding, effective thermal insulation and moisturizing measures should be taken before the concrete is in contact with the flowing surface water or groundwater, and the curing time should be extended (at least 14d) than the time specified in the above table, and the strength of the concrete should reach more than 75% of the design strength. After the end of curing, it should be backfilled in time.

2. Concrete that is in direct contact with seawater or saline soil should ensure that the concrete is not eroded before the strength reaches the design strength level. And as far as possible, the age of direct contact between newly poured concrete and seawater or saline soil should be postponed, which should not be less than 6 weeks.

3. When the average temperature of day and night is lower than 5 or the minimum temperature is lower than -3, it should be treated as winter construction. When the ambient temperature is lower than 5, it is forbidden to carry out sprinkling curing on the concrete surface. At this time, the curing liquid can be sprayed on the surface of the concrete, and appropriate insulation measures can be taken.

Different ceramsite concrete strength has different bulk density, the range of ceramsite concrete bulk density is 600-1800kg, and the strength of 1800kg is: 25mpa

Ceramsite concrete should be in the category of light concrete. The bulk density is generally less than 1500kg m3.

Good luck with your studies.

The bulk density of ceramsite concrete ranges from 600-1800kg.

Definition of ceramsite concrete:

The use of ceramsite instead of stone as the aggregate of concrete is called "ceramsite concrete". The exterior wall panels of prefabricated steel-concrete buildings are made of "ceramsite concrete". According to the use, it can be divided into thermal insulation

The density is less than 800kg m3; Structural insulation: density of 800 1400kg m3; Structural use: density of 1400kg m3 or more.

1 cubic meter of ceramsite is distributed in about 300kg to 500kg according to different varieties, that is, about tons to tons. ultra-light ceramsite 300-500 kg; fly ash ceramsite 700-900; backfill ceramsite 300-350; Clay ceramsite 210-600.

Ceramsite with a weight of more than 500 kg per cubic meter is often used for structural insulation or high-strength concrete; 300-500 is often used for thermal insulation concrete; Less than 300 is often used for extra-light thermal insulation concrete.

Ceramsite, as the name suggests, is the grain of pottery. Most of the appearance characteristics of ceramsite are round or oval spheres, but there are also some imitation gravel ceramsite that are not round or oval beam-bearing spheres, but are irregular gravel-like. According to the density, ceramsite is divided into three categories: general density ceramsite, ultra-light density ceramsite, and ultra-light density ceramsite.

General density ceramsite refers to ceramsite with a density greater than 500kg m3. Its strength is generally relatively high, and it is mostly used for structural insulation concrete or high-strength concrete. Ultra-light density ceramsiteUltra-light density ceramsite generally refers to 300 500kg m3 of ceramsite.

This kind of ceramsite is generally used for thermal insulation concrete and its products. Extra-light-density ceramsite refers to ceramsite grains that are less than 300kg m3. It has excellent thermal insulation properties, but poor strength.

It is generally used in the production of ultra-light thermal insulation concrete and its products.

Uses of ceramsite:

1. Building materials.

Ceramsite concrete has been widely used in various types of pre-components and cast-in-place concrete projects for industrial and civil buildings (such as prestressed and non-prestressed, load-bearing structures or enclosures, thermal insulation or impermeability, static load or dynamic load). Ceramsite can also be used in other building materials such as pipe insulation, furnace body insulation, cold insulation, sound insulation and sound absorption; It can also be used as soilless bed material and water filtration material in agriculture and garden.

2. Greening materials.

Because ceramsite has a special structure of porous, light weight and high surface strength, it is used for landscaping and indoor greening to meet the needs of plant moisture, and also meets the requirements of air permeability, especially its dust-free and light characteristics have been increasingly applied to the cultivation of indoor ornamental plants.

3. Dietary hygiene materials.

In addition to having porous, light and heavy, high surface strength and other physical properties, ceramsite also has a certain active substance in the production process, so it has begun to be used in drinking water, bathing and other aspects related to daily life, such as filtering drinking water in a water dispenser, increasing the activity of water in the handle of a shower and so on.

4. Industrial filter materials.

The active substance of ceramsite is also widely used in industry. The biological ceramsite filter material can be used as the biological hanging film carrier of the high-load biological filter material pool for industrial wastewater, the micro-polluted water source of tap water, the pretreated biological filter, the coarse-grained material of oily wastewater, the ion exchange resin cushion, and the microbial dry storage; It is suitable for the advanced treatment of drinking water, it has the ability to adsorb harmful elements, bacteria, and mineralized water quality in the water body, and is the filter material with the best effect of active biodegradation of harmful substances, and the best biofilm carrier in the biological filter. <>

1 cubic ceramsite is distributed in about 500kg to 300kg according to different varieties, that is, about tons to tons.

Ceramsite, as the name suggests, is the grain of pottery. Most of the appearance characteristics of ceramsite are round or oval and vertical round spheres, but there are also some imitation gravel ceramsite that are not round or oval spheres, but irregular gravel.

According to the density, ceramsite is divided into three categories: general density ceramsite, ultra-light density ceramsite, and extra-light density ceramsite.

1) General density ceramsite.

The general density ceramsite refers to the ceramsite with a density greater than 500kg m3. Its strength is generally relatively high, and it is mostly used for structural insulation concrete accompaniment or high-strength concrete.

2) Ultra-light density ceramsite.

Ultra-light density ceramsite generally refers to 300 500kg m3 ceramsite. This kind of ceramsite is generally used for thermal insulation concrete and its products.

3) Ultra-light density ceramsite.

Extra-light density ceramsite refers to ceramsite less than 300kg m3. Its thermal insulation performance is not often excellent for residual panicles, but its strength is poor. It is generally used in the production of extra-light thermal insulation concrete and its products.

Dear, I am glad to answer for you: what is the bulk density of ceramsite concrete? A1, ceramsite concrete weight is light, its dry bulk density of 800---1900kg m3, lighter than ordinary concrete 2 3-1 5, the number can reach, due to the light weight, can reduce the foundation load surplus, so can make the vertical destruction of the whole building weight reduction; Ceramsite, as the name suggests, is the grain of pottery.

Most of the appearance characteristics of ceramsite are round or oval spheres, but there are also some imitation gravel ceramsite that are not round or oval spheres, but irregular crushed stone.
