Introduction to shale modulus porous bricks, all specifications of shale porous bricks and their use

Compared with ordinary KPI and KMI bricks, the total thermal resistance of shale modulus brick wall (240 thick) is considered by considering the heat transfer resistance of air and ordinary internal and external stucco. Thermal index d=; The total thermal resistance of the shale modulus brick wall (240mm) mixed with tailings is d=, which meets the requirements of the national standard for the average thermal resistance of the wall, and all walls can meet the requirements of building warmth without using additional measures.

At the same time, the size of the modular brick is large, the surface is flat, and the corresponding building joints are few, which can reduce the amount of mortar by 15% and save labor by 30%; Its porosity is high, the bulk density is low, and the weight of the wall can also be reduced, compared with the KPI type perforated brick, the modular brick can greatly reduce the comprehensive cost of the project, improve the comfort and durability of the building, and reduce energy consumption.

Physical properties of shale modulus porous bricks (divided into main bricks, with bricks) as shown in the table:

Shale modulus porous bricks are made of shale and tailings as raw materials, and the production process of high vacuum extrusion molding and one-time code firing is adopted, and the roasting temperature reaches 1150. The porosity rate reaches more than 35%, which can reduce the weight of the wall and save the cost of foundation engineering.

Shale modulus porous brick, can be used as a load-bearing wall building material, its raw material is shale, tailings as raw materials, through high vacuum technology extrusion molding, a yard firing production process, roasting temperature up to 1150. The porosity rate reaches more than 35%, and the use of this process can reduce the self-weight of the wall and save the cost of foundation engineering. It has the characteristics of thermal insulation, heat insulation, light weight, high strength and high construction efficiency, and is a new type of building energy-saving wall material.

Shale modulus perforated brick specification *90*90 (south 240 wall) main specification.

Shale sintered hollow bricks, also known as shale sintered porous bricks. Clay, shale (weathered rock), coal gangue or fly ash are used as the main raw materials, and are roasted at high temperature in the kiln chamber, with a porosity of no more than 35% and an inner diameter of no more than 22mm in the brick. The size of the holes is small and the number is large, and it is mainly used for bricks in the load-bearing parts, referred to as shale hollow bricks.

Shale winding hollow bricks are often called red bricks, kiln bricks, shale bricks, hollow bricks, porous bricks, etc.

90 stone hollow brick wall ordinary slab brick.

The holes of sintered porous bricks are perpendicular to the bearing surface (ground) when building walls, its single hole size is small, the hole distribution is reasonable, and the non-porous part of the brick body is denser and has high strength. The production process of sintered perforated bricks and sintered hollow bricks is the same as that of ordinary sintered solid bricks, but because the body has holes, the difficulty of molding is increased, so the plasticity of raw materials is very demanding.

At present, there are many varieties of perforated brick models, which are divided into 190 bricks (large bricks, 240mm 190mm 90mm bricks (also known as 90 bricks, 240mm 115mm 90mm), long bricks (240mm 90mm 90mm), short bricks (190mm 90mm 90mm), and other varieties. 190 It is mainly used for façade building, and it is used for 80% of the bricks used on construction sites; 90 Walls for the walls of the rooms; The amount of bricks is less, and it can also be called special-shaped bricks, which are generally used to build the wall of the kitchen and toilet.

The previously common slab bricks (240mm 115mm 53mm) are solid bricks. It has the disadvantages of self-weight, small size, high production energy consumption and low construction efficiency. Replacing sintered solid bricks with sintered perforated bricks can reduce the weight of the building by about 30%, save clay by 20% and 30%, save fuel by 10% and 20%, increase the construction efficiency of the wall by 40%, and improve the thermal and sound insulation performance of the wall.

Usually under the same thermal performance requirements, the thickness of the wall built with hollow bricks is about half a brick thinner than the wall built with solid bricks, so the promotion of the use of perforated bricks and hollow bricks is one of the important measures to accelerate the reform of wall materials in China and promote the technological progress of the wall materials industry.

In addition to shale hollow bricks, there are also ordinary clay hollow bricks (mud bricks), cement hollow bricks (no sintering), and aerated blocks (cement slag plus gas autoclaved bricks) commonly used on construction sites on the market. The biggest difference between shale hollow bricks and mud hollow bricks is that shale bricks have high strength, stable molding, and resistance to weathering and rain, while mud bricks will shrink and reduce their size during the drying process of bricks and kiln roasting, and they are easy to be corroded by rain all year round. Because shale is a regional existence, it only exists in Changsha in large quantities in the southeast of the country, so the hollow brick factories in Hexi, Wangcheng, Ningxiang and other places basically only produce mud bricks.

The nearest shale hollow brick factory in Changsha Nancheng is in Dongsigang Village, Jumping Horse Township, Changsha County, about 5 kilometers east of Tongsheng Lake (Times Sunshine East Road), and the contact is 13574106965.

It is used in the same way as clay perforated bricks.

Basic specifications: 240*190*115 240*190*90 240*115*90 240*90*90 This is the main specification of the South 240 wall.

The bulk density of shale perforated bricks is 1300kg m3, the advantages of shale perforated bricks:

1. Shale sintering is more than 1200 After high temperature roasting, it is not affected by the change of thermal expansion and cold contraction in the use of construction projects.

2. The masonry wall does not need to adopt any anti-cracking and reinforcement measures, and can be directly plastered, and the wall skin does not drum and crack, which can reduce the project cost and is the preferred building material for frame structure engineering. Zheng Pai.

3. It has good sound insulation and thermal insulation effect, and is one of the green building materials that the country is currently vigorously promoting, with high strength, the average compressive strength is high, matching with the cement mortar, low water absorption, and good weathering resistance.

Shale perforated brick specifications often ridge shout size: 240 mm 115 mm 53 mm.

Size: Length, Width, Height, Common Sizes: 240 mm, 115 mm, 53 mm, and other sizes can be customized according to needs.

Porosity: The porosity of porous bricks is usually between 20% and 40%. Porosity refers to the proportion of pore space inside a porous brick.

Material: Shale porous bricks usually use natural shale as the raw material with dates, and are sintered or pressed.

Shale perforated bricks can also be used to achieve different thermal insulation, acoustic insulation and air permeability by changing the shape and density of the holes. These customization options can meet the needs of different projects, providing more flexibility and creativity.

The bulk density of shale load-bearing porous bricks is 1300kgm3, non-load-bearing shale porous bricks are 850kgm3, shale porous bricks refer to shale modulus porous bricks, shale and tailings are used as raw materials, using high vacuum extrusion molding, one-time code firing production process, and the roasting temperature reaches 1150.

The porosity rate reaches more than 35%, which can reduce the weight of the wall, save the cost of foundation engineering, and compared with ordinary sintered perforated bricks, it has special hail loss such as thermal insulation, heat insulation, light weight, high strength and high construction efficiency, and is a new type of building energy-saving wall material.

Compared with ordinary KPI and KMI bricks, the total thermal resistance of shale modulus brick wall (240 thick) is d=, considering the heat exchange resistance of air and ordinary internal and external stucco.

As we all know, most of the buildings are made of bricks, and the traditional bricks are solid bricks. At present, there is a new type of brick on the market called shale porous brick, which is not solid in the center of the source, but has the same stacking effect as solid bricks. So what are shale porous bricks?

1. What is shale perforated brick.

1.Shale porous brick is a new type of building wall material, its raw material is shale, and then the brick machine vacuum hot pressing is used to fire the molding. Secondly, it is very porous, which reduces its own weight and directly reduces the cost of foundation engineering.

In addition, it can not only build load-bearing walls, but also has a good heat dissipation function.

2.Shale porous bricks are divided into three types according to porosity: solid bricks, porous bricks, and hollow bricks. Among them, the hole of solid brick is less than 25% of the brick, and the porosity of porous brick is greater than 25%.

In general, bricks with smaller holes and more are suitable for load-bearing walls because of their higher strength. If the bricks with large holes and a small number cannot be used on load-bearing walls, such bricks are often not so strong.

Second, what are the advantages of shale porous bricks.

1.Because the shale porous brick is fired at a high temperature of 1,000 two, it will not be affected by thermal expansion and contraction in future use. Secondly, the wall of the porous masonry of the industry rock does not need to do any anti-cracking or anti-solidification treatment, as long as it is built, it can be directly plastered.

At the same time, the appearance of the wall will not appear cracks or bulges, which directly reduces the project cost and is very suitable for the use of frame construction engineering.

2.Shale porous bricks also have good sound insulation and thermal insulation effects, and are one of the green building materials vigorously promoted by the state. At the same time, shale is porous, and its strength is very high, and the average compressive capacity is high.

Secondly, it has a low water absorption rate, good weathering resistance, and it is also very convenient to pack, and has good transportation and storage performance.

3.Shale perforated bricks are nearly twice as large as traditional solid bricks, making construction efficiency much more efficient. Secondly, the appearance size deviation of shale porous brick is very small, and there will be no damage or lack of corners in use, which improves its utilization rate.
