Abstract

The invention discloses a preparation method of a jarosite slag steam-pressing brick, and relates to the technical field of building materials. The jarosite slag steam-pressing brick is prepared from,by weight, 5.6-27 parts of water, 16-45 parts of cement, 4-13 parts of jarosite slag, 104-129 parts of coarse aggregate and 60-74 parts of fine aggregate, the water cement ratio is 0.35-0.60, and 0.1-0.5 part by weight of additives are adopted. The jarosite slag steam-pressing brick prepared through the method has compressive strength, the requirements of different concrete strength grades can bemet, the problems of resource waste and environmental pollution generated by jarosite slag piling up and landfill are solved, energy conservation and environment protection are achieved, sustainabledevelopment of the resource environment is facilitated, the jarosite slag is used for partially replacing cement, the dosage of the cement is reduced, the engineering cost is lowered, the manufacturing cost of the steam-pressing brick is lowered, and the method has a wide engineering application prospect.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a method for preparing an autoclaved brick made of alum slag. Background technique

[0002] With the continuous advancement of my country's modernization process and the continuous development of the construction industry, concrete has become the most widely used material in construction projects, and the consumption of construction materials is huge. Cement is one of the important raw materials in building materials. Since the 1950s and 1960s, industrial waste residues have been used to prepare compound cement or partially replace cement, reduce the amount of cement, and solve the contradiction between supply and demand of building materials. In addition to slag, fly ash, coal gangue, carbide slag, steel slag, and flue gas desulfurization gypsum have entered the field of cement production one after another.
