1.It is heavy, increases the load-bearing of the caisson floor, and is easy to fracturing the waterproof layer, resulting in the hidden danger of water leakage;
2.Construction waste needs to be tamped, easy to puncture the waterproof layer, and sewer pipes.
Ceramsite backfill. 1.The material itself is light, 2Able to adsorb water vapor in the caisson, 3The structure is loose and does not have excessive load-bearing.
In addition, there is now a new type of backfill material, the Guards Backfill Guard.
Don't: The method is to fill the ceramsite first, and finally use cement mortar to seal it on the surface.
Performance Comparison:
1.The backfill treasure belongs to the physical filling, no gaps, no water! The ceramsite backfill is a loose filling, and the void between the ceramsite and the ceramsite is large, which can store a large amount of water and cause leakage! >>>More
Ordinary families should not forget to install water purifiers. Someone said: We drink tap water all the time. >>>More
1. The weight of ceramsite concrete is light, its dry bulk density is 800---1900KG M3, which is 2 3-1 5 lighter than ordinary concrete, and the label can reach CL5---CL60, due to the light weight, the foundation load can be reduced, so the weight of the whole building can be reduced; >>>More
The best thing is the cinders burned by the boiler.
