The performance advantages of the foam concrete, insulation performance advantages: thermal conductivity as 0.080-0.125 W / (m · k), the thermal resistance of about 20 to 30 times that of ordinary concrete. 2, the effect of noise: contains a large number of independent bubbles in the foam concrete, evenly distributed sound-absorbing capacity is five times that of ordinary concrete, with effective soundproof function. Good integrity: the scene pouring construction, closely combined with the structural layer, roof insulation layer is not detained sector every seam and breathable tube. 4, low density: dry bulk density of 250-600 kg/m3, density of 1/5-1/8 of ordinary concrete. 5, high compressive strength: a compressive strength of 1.0-6.5MPa. 6, better waterproof resistance: independent intensive bubbles and good integrity, it has a waterproof performance. 7, the swell is low: roof construction in the case without leaving any profession Gap does not produce stress deformation and uplift. 8, long life: the main project life. 9, the construction process is simple: the roof and the ground floor insulation mechanized large-scale construction, leveling layer can be used to find the slope layer and the insulation layer can be applied as one.
