Abstract

The invention discloses concrete doped with quartzite artificial stone residues and fly ash. The concrete comprises, by weight, 230-330 parts of cement, 160-175 parts of water, 740-780 parts of river sand, 1,030-1,100 parts of pebbles, 40-90 parts of quartzite artificial stone residues, 20-90 parts of the fly ash, and 4.0-6.5 parts of water reducing agent. In the concrete doped with the quartzite artificial stone residues and fly ash, the quartzite artificial stone residues and the fly ash are adopted as an admixture to replace partial cement, concrete with high water retentivity and viscidity is obtained, the shortcomings that when only the quartzite artificial stone residues are doped, the fluidity is lowered, and the strength in the later period is lowered are solved, which is beneficial to promotion of recycled utilization of the quartzite artificial stone residues, and beneficial to lowering of concrete cost, thus the ecological benefit is created, and the economic benefit is also 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 ordinary concrete doped with waste slag of quartz stone artificial stone and fly ash. Background technique

[0002] In recent years, with the rapid development of my country's artificial stone industry, the waste residue generated during the grinding process of artificial stone is increasing day by day, but the research on the recycling of quartz artificial stone waste residue is basically blank. At present, the vast majority of quartz stone artificial stone residues are still treated by traditional landfill methods, which not only occupy more land resources, but also cause pollution to water bodies and the atmosphere.

[0003] The main components of quartz stone artificial stone waste residue are silica (about 85%) and hardened unsaturated polyester resin (about 10%), in addition to a small amount of kraft paper debri...
