以矿渣、偏高岭土为主要原料,在碱性激发剂作用下形成地聚合物,并以此为胶凝材料制备地聚合物混凝土。研究了地聚合物组成材料中n(SiO2)/n(Al2O3)摩尔比、n(Na2O)/n(Al2O3)摩尔比与制备的地聚合物混凝土抗压强度之间的关系,并建立了地聚合物混凝土抗压强度与水胶比以及相同氧化物组成下地聚合物水泥净浆抗压强度之间的数学模型。研究表明:n(Na2O)/n(Al2O3)=0.3,n(SiO2)/n(Al2O3)=3.9,水胶比=3.5时,地聚合物混凝土抗压强度达到最大值;通过多元线性回归分析,建立了地聚合物混凝土28d强度(y)与净浆28d强度(x1)、水胶比(x2)之间的数学模型为:y=22.99+0.62x1-21.88x2 To slag, metakaolin as the main raw material, formed under the action of alkaline activator polymer, and as a polymer material prepared gelling materials. The relationship between n (SiO2) / n (Al2O3) molar ratio, n (Na2O) / n (Al2O3) molar ratio and the compressive strength of geopolymer concrete prepared in the geopolymer materials was studied. The compressive strength of polymer concrete with water-cement ratio, and the compressive strength of polymer cement paste under the same oxide composition. The results show that the compressive strength of geopolymer concrete reaches the maximum when n (Na2O) / n (Al2O3) = 0.3, n (SiO2) / n (Al2O3) = 3.9, , The mathematical model between the strength of 28d geopolymer (y) and the strength of paste 28d (x1) and the water-cement ratio (x2) was established as follows: y = 22.99 + 0.62x1-21.88x2
