Q:Large area ground concrete cushion seam Why is the separation of joints generally concrete: Large area of ??concrete after concrete construction, the concrete volume will be slightly inflated, the ground for a long time deposition, will be sinking, all large area of ??concrete construction, the general set of separation joints.

Q:Why calculate the amount of time to count a lot of cushion ah: Cushion cushion, as the name suggests is the structure of the liner layer, mainly from the back cover of the role, generally in the engineering design drawings have a clear approach (material).

Q:Maintenance time of the cushion on the roof of the building: According to the "concrete structure construction quality acceptance criteria" provides: Concrete should be poured within 12h after the completion of the concrete to be covered, and moisturizing conservation;

Q:What is the difference between leveling and cushion?: Cushion, the base material is not divided into materials at the same time, the design will be described. Material is the same concrete, the greater than 20CM calculated basis, less than, equal to 20CM calculated cushion. Leveling layer refers to the original structure due to the existence of uneven or slope and the laying of the base layer, is conducive to laying the surface layer or waterproof, insulation layer. The role is to play a leveling, looking for a slope or enhanced function.

Q:How to build a fine stone concrete cushion?: The cushion is primarily responsible for the load coming from the surface and passes the load evenly to the structural or base.

Q:Basement floor mattress dry to what degree can do coil waterproof?: Second, when the design of the highest groundwater level above the bottom of the basement floor, you must do waterproofing. As the waterproof waterproof effect is good, so the application of more. Internal waterproofing is generally used for repair works.

Q:Can the floor tiles be removed from the cement mats on the prefabricated board floor?: Cement cushion as a leveling layer on the floor, not designed to the structure of the load-bearing, the general can be dug, the cushion is generally 3 to 5 cm, chisel in addition to unloading the floor of the heavy objects, chisel in addition to the use of strong vibration Machine or penetrating machine is too large, with a small hammer small chisel, along the horizontal plane horizontal chisel, stripping cement cushion.

Q:Basement cushion waterproof: Fourth, improve the waterproof performance: 1, Aggregate graded concrete, is the use of different aggregates of the aggregate and improve the content of cement mortar in the concrete, so that the mortar is filled between the aggregate, thus blocking the aggregate is not dense between the seepage channel , Improve water resistance; 2, plus concrete, is added in the concrete air conditioner or dense agent to improve the impermeability.

Q:Is foam concrete suitable for use as a cushion?: And then through the foaming machine pumping system for cast-in-place construction or mold forming, the formation of natural conservation with a large number of closed pores of the new lightweight insulation materials.

Q:Is it possible to make a waterproof layer: 1, to do after the dry do, or prone to the phenomenon of wall skin off.
