Embodiment 1
[0047] 1) Carry out base-level cleaning on the concrete roof base;
[0048] 2) Determine the elevation and slope of the foamed concrete cushion, apply multiple cement mortar bubble points according to the spacing, control the elevation of each cement mortar bubble point, and then control the slope; the average thickness of the foamed concrete layer is 8cm, and the slope is 1.5% ;
[0049] 3) Add the cement to the mixer after metering, make a uniform foam from the foaming agent aqueous solution (Ketai brand polymer composite water), and then add the foam to the mixer; mix the foam and cement slurry evenly to make foam concrete material slurry; the weight ratio of cement (Conch brand ordinary Portland cement P.O42.5) to foaming agent aqueous solution is 100:61; the weight percentage of foaming agent in the foaming agent aqueous solution is 0.7%.
[0050] The prepared foam concrete slurry is pumped to the construction surface by the pouring pump for pouring, and the time interva...
