Which mortar is best to choose for building a house with autoclaved aerated blocks?

The question of whether it is good or not, and who is better, is a matter of opinion. Generally, the organization's qualifications, industry experience, external resources, and successful cases should be comprehensively evaluated and considered. It needs to be measured from the aspects that you are currently concerned about, and it cannot be said in one sentence or two.

If you want to know more details, you can consult Foshan Runhe Building Materials****. Foshan Runhe Building Materials **** is a professional sales wholesale: autoclaved aerated concrete block wholesaler.

Aerated concrete block, also known as lightweight brick, aerated brick or aerated block, is a new type of environmental protection partition wall brick, widely used in large-scale real estate interior and exterior walls, hotels, KTV partition walls, factory partition walls, office buildings and other partition wall projects. Welcome to inquire and discuss cooperation!

The mortar that matches the performance of the autoclaved aerated concrete block and can meet the construction requirements of the autoclaved aerated concrete block masonry and the masonry performance is divided into the autoclaved aerated concrete block bonding mortar suitable for the thin ash masonry method; It is suitable for autoclaved aerated concrete block masonry mortar of non-thin ash masonry method.

Mortar The strength grade of small blocks and core column concrete and masonry mortar must meet the design requirements.

Explanation of Provisions. Under normal construction conditions, the strength of small block masonry depends on the strength grade of small block and masonry mortar; ......The strength grade of small blocks and core column concrete and masonry mortar must meet the design requirements.

infill wall ......; When the autoclaved aerated concrete block masonry adopts the autoclaved aerated concrete block bonding mortar, the thickness of the horizontal ash joint and the thickness of the vertical ash joint should be 3mm 4mm.

Explanation of Provisions. The size of autoclaved aerated concrete block is larger than that of hollow brick and light aggregate concrete small hollow block, so when it adopts ordinary masonry mortar, the thickness of the horizontal ash joint and the width of the vertical ash joint of the masonry are larger. The ash joints are too thick and too wide, which is not conducive to the control of masonry cracks. When the autoclaved aerated concrete block is constructed by the thin ash masonry method with aerated concrete bonding mortar, the horizontal ash joint thickness and vertical ash joint width can be greatly reduced.

At this point, your question: "Do autoclaved sand aerated concrete blocks have to be built with special adhesives?" "I think:

Although the specification does not prescribe. But in combination with the term: special mortar for autoclaved aerated concrete blocks, it should be used:

Special mortar for autoclaved aerated concrete blocks. From a practical point of view, the masonry cracks of the masonry using the special mortar for autoclaved aerated concrete blocks are less than those without the special mortar for autoclaved aerated concrete blocks.

Due to the characteristics of water absorption, the mortar used in the autoclaved aerated block needs to add a water-retaining agent, which is called special masonry mortar (also called special binder), special plastering mortar and special interface mortar.

In the current building construction process, these problems are common in the construction of autoclaved aerated concrete blocks: cracking of ash joints, cracking of plastering layer, hollowing, leakage, and reduction of sound insulation effect.

1.Aerated concrete blocks have a large air attack rate and high water absorption. Therefore, it shall not be built below the elevation of the building or long-term flooding or often subject to alternating dry and wet parts.

At the bottom of the block wall, small blocks of solid masonry should be used, and its height should not be less than 200mm. There should be three layers of waterproof mortar in the brick masonry, and there should be waterproof mortar between the brick masonry and the aerated concrete.

2.The aerated concrete block has low surface strength, and it is easy to lack corners or fracture in the process of transportation and handling, which increases the loss and waste of materials, so it should be operated carefully in the transportation and handling process.

3.The surface of aerated concrete blocks is easy to powder, and it is not easy to bond better with mortar. Therefore, the block wall should be built with a special mortar with good adhesion, and the cement lime mixed mortar can also be used, and the strength grade of the mortar should not be less than; For exterior walls, not less than m5, the mortar must be stirred evenly, mixed with the mix, the consistency of the mortar is 5cm 7cm is appropriate.

The walls should be brushed and dura fibers added to the plastering mortar before interior plastering and exterior priming.

4.If the aerated concrete block wall directly reserves the door and window opening, it is easy to cause water seepage or water leakage at the door and window side, so it is advisable to use 1:1 when dealing with the door and window frame plug joint

2. The expanded cement mortar is mixed with 108 glue for plugging, the substrate is cleaned before plugging and brushed with cement slurry, first filled with styrofoam, and then caulked with cement mortar to ensure that the edge of the frame is dense and seamless, and finally the waterproof glue is played on the outside.

5.The production age of aerated concrete blocks is 28 days, so the first amount is limited to a certain extent, and it is not suitable for small-scale production. This causes inconvenience when choosing a supplier.

Foam concrete block, with the characteristics of fire resistance, heat insulation, light weight, seismic resistance, etc., is a new type of lightweight porous energy-saving material that is mixed and poured by air foam, cement, aggregate, etc. According to the company's technical personnel, this material can be produced by a large number of industrial wastes such as fly ash, slag and stone powder, thereby reducing waste emissions, effectively improving ecological conditions and protecting the ecological environment.

It must be a good steaming and curing, the steaming bricks are strong, the density is high, and the load-bearing is good

Are foam concrete blocks autoclaved.

If it is autoclaved.

The quality is the same as that of steam-cured concrete aerated blocks.

If it is autoclav-free.

Steaming aerated block ***.

Autoclaving-free concrete blocks can not be used to meet the national requirements aerated concrete block equipment fly ash brick equipment lime sand brick equipment manufacturer Henan Shenglong Machinery.

The quality depends on what is used, thermal insulation, light weight, sound insulation foam concrete.

Steam-cured concrete aerated blocks are a little better!
