Abstract

The invention discloses a concrete doped with quartz stone artificial stone waste residues. The concrete comprises, by weight, 320-400 parts of cement, 150-180 parts of water, 759-800 parts of river sands, 1000-1100 parts of stones, 20-80 parts of quartz stone artificial stone waste residues and 5.5-6.4 parts of a water reducer. The quartz stone artificial stone waste residues are used as an admixture to substitute parts of cement in order to reduce the use amount of cement in per square of the concrete, and a low water-binder ratio is adopted to guarantee the late strength of the concrete, so the cohesiveness and the water retention of the concrete are improved, the reduction of separation, water segregation and other adverse phenomena of the concrete is facilitated, the recycling of the quartz stone artificial stone waste residues is promoted, the reduction of the cost of the concrete is facilitated, the ecologic benefit is created, and the economic benefit is obtained.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a structural material for building, in particular to concrete mixed with waste slag of quartz stone and artificial stone. Background technique [0002] C30 concrete is currently widely used in my country's construction field, but due to the high water-binder ratio used in the preparation process, it is prone to segregation, bleeding and other adverse phenomena, resulting in poor durability of hardened concrete and easy failure of strength. Standard requirements, lower strength class. [0003] In recent years, with the rapid development of my country's artificial stone industry, the waste slag generated during the grinding process of artificial stone is also increasing, but the research on the recycling of quartz artificial stone waste slag is basically blank. At present, the vast majority of quartz stone artificial stone residues are still treated by traditional landfill...
