Abstract

An iron tailings powder foam concrete and a preparation method thereof, the amount of each raw material in each cubic meter of concrete is as follows: cement: 240kg-360kg; water: 120kg-200kg; iron tailings powder: 160kg-220kg; hydroxypropyl cellulose: 0.08kg~0.12kg; aluminum powder: 2kg~3kg; foam: 0.59m3~0.86m3; the foam is diluted with water at a weight ratio of 1:35~1:50 by the foaming agent, and evenly sprinkled into the Hydroxypropyl cellulose, which accounts for 0.05% of the weight of the foaming agent diluted solution, is fully stirred and foamed by foaming equipment. The strength of the invention is 20% higher than that of ordinary foam concrete, and the durability is better, and there is no increase in the number of large holes and harmful holes. The invention improves the utilization rate of iron tailings powder, improves the role of foam concrete in building energy saving and building industrialization development, and can be safely applied to actual projects.

Description

technical field [0001] The invention relates to a foam concrete prepared from iron tailings and a preparation method thereof. Background technique [0002] Since entering the 21st century, building energy conservation and environmental protection have attracted more and more attention, and a large number of policies related to building energy conservation have been continuously implemented. At the same time, my country's economy is developing rapidly, but the comprehensive utilization of iron tailings has not kept up with the speed of economic and social development, and cannot meet the requirements of economic and social development. my country is continuously strengthening the comprehensive utilization of iron tailings, and gradually improving the comprehensive utilization rate of iron tailings in my country through technological breakthroughs and the promotion of scientific and technological achievements. [0003] Iron tailings are screened and used as by-product artific...
