Technical knowledge of exterior wall insulation/coating
- Time of issue:2018-04-18 00:00:00
Thermal insulation:the thermal conductivity is 0.06 to 0.28W/(M.K),and the thermal resistance is about 10-20 times that of ordinary concrete.
Lightweight:the dry volume density is 300-1600kg/M3,which is about 1/5~1/8 of the normal cement concrete,which can reduce the overall load of the building.
Integrity:it can be used for on-site pouring construction,which is closely combined with the main project,without the need to leave the boundary crack and the air pipe.
Low elastic damping property:the porosity of foaming cement makes it have low elastic modulus,so that it can absorb and disperse shock load well.
Sound insulation:the foaming cement contains a large number of independent bubbles and is uniformly distributed.The sound absorption capacity is 0.09 to 0.19 percent,5 times that of ordinary concrete,and it has the function of effective sound insulation.
Compressive strength:the compressive strength is 0.6-25.0mpa.
Water resistance:the foaming cement is less absorbent,relatively independent sealing bubbles and good integrity,so that it has a certain waterproof performance.
Durability:same life as the main project.
The construction is simple:it only needs to use the cement foaming machine to realize automatic operation,which can realize long-distance transportation of vertical height of 200 meters,and the workload is 150-300m3/working day.
Production processability:foamed cement can not only production into all kinds of products in the factory,and still can field construction,cast-in-situ directly into roofing,ground and wall body,and can be saw,planer,hammer,drilling and other processing.
Environmental protection:the raw materials needed for foaming cement are cement and foaming agent,and the foaming agent is neutral,free of benzene,formaldehyde and other harmful substances,avoiding environmental pollution and fire hazards.
Fireproofing property:because the main raw material of foaming cement is cement,cement belongs to inorganic material completely fireproofing
Economy:low comprehensive cost.
