Large-dosage steel slag solid wastewater industrial ecological frame concrete and proportion determination method thereof
The invention discloses a large-dosage steel slag hydraulic ecological frame concrete and a proportion determination method thereof, and the method comprises the following steps: any given steel slag aggregate is screened through a 4.75 mm square hole sieve and a 9.5 mm square hole sieve, the steel slag aggregate is divided into a coarse particle part and a fine particle part, the volume ratio of the steel slag aggregate to replace the aggregate is set, and according to the volume ratio of the coarse particles and the fine particles in the steel slag aggregate, gravels and sand in concrete are replaced according to the target volume replacement rate; and the replacement proportion of the sandstone is adjusted according to the fineness modulus and the particle size of the steel slag aggregate fine particles, so that the large-dosage steel slag hydraulic ecological frame concrete with good mixture performance can be obtained. The steel slag aggregate is further ground to replace a cementing material, and finally the utilization rate of the steel slag solid waste in the hydraulic ecological frame concrete reaches 27%-47%.
本发明公开一种大掺量钢渣水工生态框混凝土及其配比确定方法，该方法包括：将任意给定的钢渣骨料，通过4.75mm方孔筛和9.5mm方孔筛进行筛分，将钢渣骨料分为粗颗粒部分和细颗粒部分，设定钢渣骨料取代骨料的体积比例，根据钢渣骨料中粗细颗粒的体积比例，分别按目标体积取代率取代混凝土中的碎石和砂，并根据钢渣骨料细颗粒的细度模数和颗粒级配对砂石被取代的比例进行调整，可以得到拌合物性能良好的大掺量钢渣固废水工生态框混凝土配比。通过进一步将钢渣骨料粉磨后取代胶凝材料，最终实现水工生态框混凝土中钢渣固废的利用率达到27％～47％。
