Main features:
one 、 Good thermal insulation H2 Foam concrete has lower thermal conductivity than aerated concrete, perlite and 30%~50% , low thermal conductivity compared with ceramsite concrete 70% , and poly benzene Quasi extrusion Insulation board （ XPS Compared with plate), the thermal conductivity is about high 45% , thermal conductivity is 0.060~0.115W/(mk) It can also be used for slope making, leveling and thermal insulation.
2、 Light weight, good compressive strength H2 The strength of foam concrete is equivalent to that of aerated concrete and ceramsite concrete, and higher than that of expanded perlite 2~3 The capacity can be constructed according to the requirements of architectural design drawings.
3、 Simple construction and short construction period H2 When foam concrete is used in roof construction, on-site pouring is adopted. The slope making layer, leveling layer, insulation layer, protective layer, etc. are completed at one time. Compared with the construction period required by traditional roof construction, more than one-third of the construction period can be saved. Its raw materials are mainly cement 、 foaming agent 、 auxiliary Etc.
4、 Poor water absorption and good water resistance H2 Compared with aerated concrete, ceramsite concrete and perlite, the water absorption of lightweight foam concrete is 1/2 lower.
5、 Low elasticity and shock absorption, good seismic resistance H2 The porosity of lightweight foam concrete makes it have low and large elastic modulus, which makes it have good absorption and dispersion effect on impact load; In addition, the smaller the load of the foundation, the stronger the seismic resistance. Therefore H2 The seismic performance of foam concrete buildings will increase.
6、 Sound insulation and fire resistance H2 The lightweight foam concrete contains a large number of individual bubbles, which are evenly distributed, and the sound absorption capacity is 0.08%~0.18% , ordinary concrete four Times, with effective sound insulation function. It is incombustible and has a fire resistance limit of more than three hours, which is beyond the reach of other materials.
7、 entirety H2 Light foam concrete can be poured on site and closely combined with the main structural layer.
8、 Environmental protection H2 The main raw materials required for lightweight foam concrete are cement and foaming agent. The foaming agent is neutral and does not contain harmful substances such as benzaldehyde, which avoids environmental pollution and fire hazards.
