基于单纯形重心设计法的掺合料混凝土配合比设计

摘要:
采用单纯形重心设计法预测复合胶凝材料28d抗压强度;将复合胶凝材料28d抗压强度预测值和已设定的水胶比代入Bolomy公式测算掺合料混凝土28d抗压强度.结果表明:用单纯形重心设计法能较准确预测复合胶凝材料28d抗压强度;将复合胶凝材料28d抗压强度预测值和已设定的水胶比代入Bolomy公式能较准确地测算出掺合料混凝土28d抗压强度.在确定复合胶凝材料组成后,用单纯形重心设计法预测复合胶凝材料抗压强度,然后和设计要求的掺合料混凝土抗压强度一起代入Bolomy公式,就能得到较准确的掺合料混凝土水胶比,再通过体积法就可较准确地求得掺合料混凝土配合比.这种掺合料混凝土配合比设计法视复合胶凝材料各组分为与水、集料一样的独立组分.

Abstract:
The 28d compressive strength of compound binder was predicted by simplex centroid experimental design. According to the predicted 28d compressive strength of compound binder and the known water binder ratio, the 28d compressive strength of concrete with admixture was estimated with Bolomy formula. The results show that the 28d compressive strength of compound binder can be predicted relatively correctly by simplex centroid experimental design,and the 28d compressive strength of concrete with admixture can be foreseen relatively correctly by substituting the predicted 28d compressive strength of compound binder and the known water binder ratio into Bolomy formula. The water binder ratio of concrete with admixture can be calculated relatively correctly by substituting the predicted compressive strength of compound binder and the design compressive strength of concrete with admixture into Bolomy formula. So the mix proportion of concrete with admixture can be obtained relatively correctly with absolute volume method. By using this mix proportion design of concrete with admixture, the each composition of compound binder can be regarded as independent component of concrete like water or aggregate.
