Embodiment 1
[0044] The cast-in-place lightweight concrete wallboard of the present invention includes a wallboard body and a layer of welded steel mesh placed therein. The optimal weight of each component of the wallboard body is as follows, calculated as a total amount of one cubic meter of mixture:
[0045] Water: 200kg / m 3 ,
[0046] Cement: 42.5# Portland cement, 250kg / m 3 ,
[0047] Admixture: Among them, fly ash: 150kg / m 3 ,
[0048] Slag fine powder: 80kg / m 3 ,
[0049] Silica fume: 20kg / m 3 ,
[0050] Water reducer: 8kg / m 3 ,
[0051] Polypropylene fiber (PPY): 1kg / m 3 ,
[0052] Alkali-resistant plastic-coated glass fiber chopped strand: 2kg / m 3 ,
[0053] Cement modified polymer resin emulsion: 5kg / m 3 ,
[0054] Ceramsite: 400kg / m 3 ,
[0055] Pottery sand: 300kg / m 3 ,
[0056] Medium sand: 100kg / m 3 ,
[0057] Wherein, the weight ratio of water to gelling material is 0.4.
[0058] The above-mentioned components for making light...
