Interface mortar for autoclaved aerated concrete

Abstract

The invention discloses interface mortar for autoclaved aerated concrete. The interface mortar consists of the following components in percentage by mass: 42% of cement, 28.1-44.96% of yellow sand, 11.24-28.1% of tailing iron sand, and 1.8% of additive. With the adoption of the interface mortar for autoclaved aerated concrete disclosed by the invention, the tailing iron sand replaces a part of yellow sand as aggregate to prepare the interface mortar for autoclaved aerated concrete under the premise of ensuring the same property of the interface mortar for the autoclaved aerated concrete, thus not only the stacking problem of the tailing iron sand is solved, but also the cost of the interface mortar for the autoclaved aerated concrete is reduced; and meanwhile, the environment damage caused by the tailing iron sand is avoided as well.

Description

technical field [0001] The invention relates to dry-mixed mortar, in particular to an interface mortar for autoclaved aerated concrete. Background technique [0002] The existing dry-mixed mortar needs to be mixed with a large amount of natural sand. However, the natural sand resource is a non-renewable resource in a short period of time. In many areas of my country, the natural sand resource is nearly exhausted and its quality is declining. In addition, for the consideration of flood control and ecological balance, the country has expressly banned the mining of natural sand in some river sections, making natural sand resources increasingly scarce. With the increasing development of infrastructure construction, the demand for natural sand resources is increasing day by day. [0003] Contrary to the increasing shortage of natural sand resources, there are currently more than 8,000 state-owned mines and collective mines in my country, which produce up to 500 million tons of t...

AI Technical Summary

Problems solved by technology

Tailings are industrial solid wastes after mine mining. According to relevant data, a large number of stacked tailings not only cause serious pollution to air, water and soil, but also occupy a large amount of agricultural land, especially if the tailings ponds are poorly managed and designed. , prone to collapse accidents, causing casualties, property losses and large-scale environmental pollution
