Foamed concrete, preparation method thereof and composite material
The invention relates to foamed concrete, a preparation method thereof and a composite material. The foamed concrete is prepared from the following raw materials in parts by weight: 621-750 parts of cement; 212-280 parts of fly ash; 30-70 parts of saponin type foaming agent; 20-45 parts of a silane-based water repellent; and 35-65 parts of a propenyl ether copolymer. The foamed concrete has the characteristics of light weight, high strength, fire resistance and hydrophobicity. According to the composite material, the dry density can be stabilized within the range from 300kg/m < 3 > to 700kg/m< 3 >, and meanwhile, the compressive strength of 3.5 MPa or above is achieved.
本发明涉及一种发泡混凝土及其制备方法和复合材料。以重量份数计，所述发泡混凝土的制备原料包括：水泥621份‑750份；粉煤灰212份‑280份；皂角苷型发泡剂30份‑70份；硅烷基憎水剂20份‑45份；丙烯基醚共聚物35份‑65份。本发明所述发泡混凝土具有轻质高强、防火憎水的特点。所述复合材料能够将干密度稳定在300kg/m3‑700kg/m3范围内，同时，达到3.5MPa以上的抗压强度。
