What is the difference between concrete solid bricks and standard bricks

Concrete solid bricks.

It is a classification of standard bricks.

Concrete solid bricks: concrete solid bricks (hereinafter referred to as bricks) supported by cement, aggregates, admixtures, admixtures, etc. added with water, stirring, forming and curing.

Solid concrete bricks are marked in the following order: code, size, strength class, density class, and standard number. Tag examples:

The specifications are 240mm, 115mm, 53mm, and compressive strength.

The grade is MU25, the density grade is B, and the qualified concrete bricks are marked as: SCBMU25BGB T

The solid standard brick weight of 240mm 115mm 53mm is 1800 1900kg m3

529 standard bricks per cubic meter.

Solid bricks are for hollow bricks.

Standard bricks are for non-standard bricks. The size of the standard brick is 240 115 53mm.

Concrete solid bricks and standard bricks have a difference in compressive strength and specific gravity.

Concrete solid bricks: concrete solid bricks (hereinafter referred to as bricks) supported by cement, aggregates, admixtures, admixtures, etc. added with water, stirring, forming and curing. Yajie pipe is mainly used for masonry walls. In recent years, it has become more and more widely used.

Solid bricks are for hollow bricks.

Standard bricks are for non-standard bricks. The size of the standard brick is 240 115 53mm.

Standard brick, refers to the size of 240mm 115mm 53mm solid standard brick weight of 1800 1900kg m3

529 standard bricks per cubic meter.

Concrete solid brick is a solid brick made of concrete composed of cement, aggregate, admixture, admixture, etc., which is stirred, formed and cured by adding water. It is mainly used for masonry walls.

Cement Solid Brick Specifications:

Length, width, height: 290,240,190,180; 240，190，115，90； 115，90。

Intensity classes: MU30, MU25, MU20, MU15 and MU10.

30% porosity.

Such as Zhejiang Province provincial standard specifications: length, width, height: 240 115 90, 240 240 90, 120 115 90, 180 115 90, 240 115 53, 190 190 90, 190 90 90, 190 90 53.

Because of the use of matching bricks: such as half bricks, seven-point bricks). , concrete solid bricks seem to have no specification, but there are indeed on the market, specifications 240 115 90 for more, strength requirements must be achieved, strength grades: MU30, MU25, MU20, MU15 and MU10.

1. Different compositions: concrete solid bricks.

Concrete solid bricks supported by cement, aggregate, fly ash and admixtures and admixtures added as needed, etc., are stirred, formed and cured with water. Red bricks are made of clay, shale, gangue.

It is a sintered building brick made of raw materials, crushed, mixed and kneaded by manual or mechanical pressing, and then dried at a temperature of about 900 degrees Celsius and fired by an oxidation flame.

2. Different uses: standard bricks.

I can do load-bearing walls.

Can also be used to fill walls. The grace of solid concrete brick blocks can be used to fill walls.

3. Different densities: the standard brick density is 1800 1900kg m3. Concrete solid bricks are divided into three density grades: grade A (2100kgm), grade B (1681kgm 2099kgm) and grade C (1680kgm) according to the density of the concrete itself.

According to the density of the concrete itself, it is divided into three density grades: grade A (2100kg), grade B (1681kgm 2099kgm) and grade C (1680kgm).

Depending on the shape and use, permeable bricks.

There are also the following specifications:

1. Square brick (200*200*50, 250*250*40, 300*300*50, 400*400*50).

2. Road bricks (100*200*50 115*230*50).

3. Grass lattice parking lot bricks (200*400*50 200*250*60).

4. Blind road brick (300*300*50 250*250*30).

Rank on behalf of the triumphant defeat mark.

Density class. According to the density of the concrete itself, it is divided into three density grades: grade A (2100kg), grade B (1681kgm 2099kgm) and grade C (1680kgm). Oak feast.

Label beam Sun Yinji: The product is marked in the following order: code, specification size, strength grade, density grade and standard number.

Marking example: 240mm 115mm 53mm, compressive strength.

Grade MU25, density grade B, qualified concrete bricks:

The above content reference: Encyclopedia - concrete solid brick.

The specification of cement solid brick is: 240*115*9mm.

The cost of production of cement bricks.

The market price will vary depending on the cost of raw materials and other expenses in different regions. Red bricks are significantly more cost-effective. Using high-pressure molding technology, cement bricks have good compactness, low water absorption, good frost resistance and high strength.

With these advantages, it can be applied to various urban construction projects.

More than 80% of the stone powder, waste stone or construction waste can be mixed into the environmentally friendly cement bricks.

In addition to reducing the cost of raw materials, you can also enjoy tax exemption policies.

Summary. Concrete solid bricks made of cement, aggregates, admixtures, admixtures, etc., are stirred, formed and cured with water.

What mortar is used for concrete solid bricks masonry.

Cement mortar is commonly used for foundation mortar. Marking M5 and above. There is no basis for this, this is a macro and defeat ratio.

Anti-crack mortar, bonding mortar, masonry mortar, etc. Marking of cement mortar: The marking of mortar is, M5, M10, M15, M20, M25, M30, M40.

Mortar is divided into masonry, plastering, and joints according to its use, and has nothing to do with the label. Anti-crack mortar, which is made of anti-crack agent, cement and sand made of polymer emulsion and admixture with water in a certain proportion to meet a certain deformation and maintain no cracking. Adhesive mortar is made of cement, quartz sand, polymer cementing material with a variety of additives and mechanical mixing.

It is mainly used as a binder for bonding insulation boards, also known as polymer insulation board bonding mortar. The adhesive mortar is made of high-quality modified special cement and a variety of polymer materials and fillers through unique composite technology, with good water retention and high paste strength. The mortar that turns bricks, stones, blocks and other blocks into masonry is called masonry mortar.

It plays the role of bonding, padding, and force transmission, and is an important part of masonry. Cement mortar is suitable for masonry in a humid environment and masonry with high strength requirements; Cement-lime mortar should be used for masonry in a dry environment; The walls of multi-storey houses are generally made of cement-lime mortar with a strength grade of M5; Brick columns, brick arches, reinforced brick lintels, etc. generally use cement mortar with a strength grade of m5 m10; The brick foundation is generally made of cement mortar not less than m5; Low-rise houses or bungalows can be made of lime mortar; Simple houses can be made of lime clay mortar.

Concrete solid bricks. Specifications 240 mm 115 mm 53 mm, ** between 2 4 yuan.

1. The density grade is divided into three density grades: grade A (2100kg m), grade B (1681kg m 2099kg m) and grade C (1680kg m) according to the density of the concrete itself.

2. Strength grade, compressive strength of bricks.

It is divided into six grades: MU40, MU35, MU30, MU25, MU20, and MU15.

3. Marking, the product is marked in the following order: code, specification size, strength grade, density grade.

Marking example: Specification 240mm 115mm 53mm, compressive strength grade MU25, density grade B, qualified concrete bricks:

Structure. 1. Clay: It should contain a certain amount of loose particles to facilitate mixing cement. Clay with less sand content can be mixed with sand in the soil. Clay with less sand content and harder clay must be ground and then mixed with sand.

2. Cement: mixed with 10% 425 ordinary Portland cement.

It can improve the strength and water resistance of bricks, and it will not crack after immersion. Otherwise, the bricks will crack in general.

3. Admixture: Mixed with a small amount of admixture (strengthening Wang deficiency agent), in addition to improving the induration strength of bricks, it can also reduce the amount of cement and reduce the cost of rolling products.
