Precise design method for ultra-high performance HUPC concrete mix proportion
The invention discloses an ultra-high performance HUPC concrete mix proportion accurate design method, and relates to the technical field of concrete.The method comprises the following steps that the optimal mass ratio of two-size-fraction combination is calculated, the optimal mass ratio of three-size-fraction combination is calculated, calculation and adjustment of preliminary proportion composition design are conducted, and performance comparison is conducted. On the basis of mastering basic data of various raw materials, accurate positioning is carried out, the optimal percentage composition of cement microbead silica fume is calculated firstly, and then the ratio of the cement microbead silica fume to the cement microbead silica fume is calculated according to 4.75 mm, 2.36 mm, 0.6 mm, 0.075 mm and 1t in each square of material; the composition of each material in each square is accurately calculated through a trial algorithm according to the rule of grading combination of 0.075 mm (cement, stone powder, microbeads and silica fume), so that the most compact structure is met.
本发明公开了一种超高性能HUPC混凝土配合比精准设计方法，涉及混凝土技术领域，包括以下步骤：求算两粒级组合的最佳质量比、求算三粒级组合的最佳质量比、初步配比组成设计的计算与调整和性能比较，在掌握各种原材料基础数据的基础上，精准定位,先求出最佳的水泥微珠硅灰的百分组成,然后依据每方材料中4.75mm，2.36mm，0.6mm，0.075mm，<0.075mm(水泥，石粉，微珠，硅灰)级配组合的规律，通过试算法，精准计算出每方各材料的组成，使符合最为密实的结构。
