Design method for quantifying mix proportion of full-machine-made sand concrete
The invention relates to a design method for quantifying the mix proportion of all-machine-made sand concrete. The design method comprises the following steps: S1, calculating the mixing amount of fly ash, the mixing amount of mineral powder, the influence coefficient of mineral admixtures and the water-binder ratio; s2, calculating the use amount of a rubber material; s3, calculating the dosage of an additive, the dosage of fly ash, the dosage of slag powder and the dosage of cement; s4, respectively calculating the use amount of coarse aggregate and the use amount of fine aggregate; and step S5, performing concrete trial preparation, adjustment and determination according to the use amount of the raw materials. According to the method, the conditions that in the related technology, when the mix proportion is designed, part of data needs to be obtained by looking up a table, the calculation efficiency is low, comprehensive consideration of the content of stone powder, the using amount of a water reducing agent and the fineness modulus of sand in all-machine-made sand is lacked, and consequently the actual concrete preparation strength and the expected preparation strength are large in input and output are improved.
本发明涉及一种量化全机制砂混凝土配合比的设计方法，包括：步骤S1，计算粉煤灰掺量、矿粉掺量、矿物掺合料影响系数及水胶比；步骤S2，计算胶材用量；步骤S3，计算外加剂用量、粉煤灰用量、矿渣粉用量及水泥用量；步骤S4，分别计算粗骨料用量及细骨料用量；步骤S5，根据原料用量进行混凝土试配、调整与确定。改善了相关技术中，设计配合比时，部分数据需要查表获取，计算效率较低，缺少对全机制砂中的石粉含量、减水剂用量及砂细度模数的综合考量，导致实际混凝土配制强度与预期配置强度出入较大的情况。
