Abstract

The invention provides a wall brick prepared by virtue of ready-mixed concrete waste slurry. The wall brick prepared by virtue of ready-mixed concrete waste slurry is mainly prepared from the following components in parts by weight: 600-800 parts of pressure-filtered slurry, 40-140 parts of cement, 1-1.4 parts of calcium lignosulphonate, 25-125 parts of water, 800-950 parts of artificial sand and 400-550 parts of iron tail slag, wherein the components are measured in parts by weight. The wall brick utilizes the slurry generated by ready-mixed concrete enterprises and the waste liquid generated during paper-making, and is low in cost, green and environment-friendly, and high in economic benefits; the prepared wall brick is high in compressive strength and good in freezing-thawing resistance.

Description

technical field

[0001] The invention belongs to the field of building materials, in particular to a wall-laying brick prepared by using ready-mixed concrete waste slurry. Background technique

[0002] At present, my country's annual concrete output exceeds 1.5 billion cubic meters, and the average production of 1 cubic meter of concrete produces 0.03 tons of slurry, that is, my country's ready-mixed concrete enterprises produce about 50 million tons of slurry every year.

[0003] At present, the waste slurry treatment technologies of ready-mixed concrete enterprises mainly include:

[0004] 1. Static sedimentation efflux treatment method

[0005] The generated slurry water is collected into the multi-stage sedimentation tank, and the supernatant produced after the slurry water settles can be used for the production of ready-mixed concrete. After the sediment accumulates to a certain amount, it is dug out by a forklift and discharged as construction waste. The sediment in t...
