Abstract

The invention discloses a lightweight thermal insulation muck standard brick and a preparation method thereof. The lightweight thermal insulation muck standard brick disclosed by the invention is prepared from the following raw material components by mass percentage: 45%-65% of muck, 10%-20% of modified polystyrene foam particles, 3%-7% of ordinary Portland cement, 15%-20% of slag, 0.3%-0.9% of Na2SO4, and 2.4%-12.1% of water, wherein the sum of the mass percentages of all the components is 100%. The lightweight thermal insulation muck standard brick disclosed by the invention has the characteristics of high compressive strength, simple production process, no efflorescence, no steaming and no burning. The muck is used as a main raw material to prepare the lightweight thermal insulation muck standard brick to realize the resource utilization of the muck and effectively solve the problems of occupying cultivated land and polluting air by the muck, and the finished brick produced satisfies the operational performance and meets national environmental protection standards, the economic benefit and environmental protection benefit are obvious, and a broad market promotion prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of fire-free bricks for construction engineering, and in particular relates to a light-weight thermal insulation slag standard brick and a preparation method thereof. Background technique [0002] my country's construction waste is a new source of raw materials that the brick and tile industry has been involved in in recent years. On the one hand, there are more and more underground projects attached to high-rise buildings, the wide application of urban subway construction, and the construction of pouring foundation piles, etc., all produce a large amount of construction dregs; on the other hand, the cleaning of construction dregs not only requires a lot of Human, material and financial resources, there are also hidden dangers such as secondary disasters; third, the disposal of construction waste is becoming more and more difficult, not only occupying land resources, but also causing environmental pollution....
