Concrete mix proportion design method
The invention relates to a concrete mix proportion design method which comprises the following steps: S1, determining a water-binder ratio and theoretical water consumption according to preset concrete strength grade and slump as well as performance parameters of concrete, and further determining the water consumption according to preset admixture dosage; s2, determining the use amount of a cementing material according to the preset anti-permeability grade of concrete and the water-binder ratio and the use amount of water obtained in S1, and determining the use amount of each component in the cementing material; and S3, according to the performance parameters of each component in the concrete and the water-binder ratio obtained in the S1, determining the sand ratio required for reaching the strength grade and the impermeability grade of the concrete, and further determining the dosage of each component in the aggregate. Based on preset concrete working performance indexes, by adjusting the water-binder ratio and the sand ratio, the requirement for dual control over the strength grades of C50, C55 and C60 and the anti-permeability grades of P10 and P12 of concrete is met, and operation is easy and convenient.
本发明涉及一种混凝土配合比设计方法，其包括以下步骤，S1根据预定的混凝土的强度等级和坍落度、以及所述混凝土的性能参数，确定水胶比和理论用水量，进而根据预定的外加剂掺量，确定水的用量；S2根据预定的混凝土的抗渗等级、以及所述S1得到的水胶比和水的用量，确定胶凝材料的用量，并确定胶凝材料中各组分的用量；S3根据混凝土中各组分的性能参数、以及所述S1得到的水胶比，确定能够达到混凝土的强度等级和抗渗等级所需的砂率，进而确定骨料中各组分的用量。本发明基于预定的混凝土工作性能指标，通过调整水胶比和砂率，达到了混凝土的C50、C55、C60强度等级及P10、P12抗渗等级双重控制的要求，操作简便。
