摘要:
通过单纯形重心设计方法得出了水泥-磨细矿渣微粉-超细粉煤灰三元复合胶凝材料组成与各龄期混凝土抗压强度的定量数学解析式,其对混凝土强度的预测精度基本可控制在5%的相对误差范围内.不同龄期三元系统的等强线变化揭示了3 d和28 d时,复合胶凝材料各组分对强度的贡献按水泥、磨细矿渣微粉、超细粉煤灰的顺序降低,180 d时则按水泥、超细粉煤灰、磨细矿渣微粉的顺序降低, 从而揭示了磨细矿渣微粉与超细粉煤灰复合对混凝土早期和后期强度存在互补效应.
Abstract:
A quantitative mathematics function about the relationships between the compressive strength of the concrete and the compositions of ternary blended binders of cement-pulverized slag powder-superfine class F fly ash was educed by means of simplex-centroid experimental design. The function can forecast the compressive strength of the concrete within a relative error of 5%. The iso-strength shape at different curing age demonstrates clearly that the contribution of the composition of blended binders to the compressive strength of the concrete is reducing in the order of cement, pulverized slag powder and superfine class F fly ash at 3 d and 28 d, but in the order of cement, superfine class F fly ash and pulverized slag powder at 180 d. The mutual complementarity effect of pulverized slag powder and superfine class F fly ash to the compressive strength of the concrete at early and later age is revealed obviously.
