Problems solved by technology

Since there is currently no feasible harmless treatment and reuse of magnesium slag, the discharge of solid waste that is higher than the proportion of the product not only needs to occupy land, but also pollutes the air and water sources with the wind and rain.
The quantity and harm of magnesium slag are a big burden for magnesium production enterprises

Embodiment 1

[0022] Take 100 parts by weight of magnesium slag; 2 parts by weight of composite activator; 50 parts by weight of foundry sand; 50 parts by weight of slag; 20 parts by weight of slag powder; 20 parts by weight of diatomite; 20 parts by weight of cement; 5 parts by weight of crushed straw; 5 parts by weight of polyacrylonitrile fiber; 5 parts by weight of polyvinyl formal water-soluble polymer.

[0023] Chenfu in magnesium slag water for 3 days, after drying, grind into powder, powder particle size 2000cm 2 / g. Diatomaceous earth was calcined at 600°C for 2 hours, and ground into 1500cm 2 / g particle size powder. The slag is ground into 3000cm 2 / g of powder. Slag or broken into particles with a particle size of 5-20mm. The foamed EPS particles are treated with a surface treatment agent composed of cement and polymer latex or redispersible polymer latex powder at a ratio of 0.05-2. The straw is broken into pieces with a length of 5-20 mm.

Abstract

A small-size hollow building block is prepared from magnesium dregs, composite trigger, light aggregate, and optional slag powder, calcined and ground idatomite, cement, EPS particles, and broken straw, stalk, fibers and polymer through mixing, stirring, moulding, demoulding and curing.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to wall masonry materials. Background technique [0002] Magnesium slag is the waste slag produced during the smelting of metal magnesium. For every ton of magnesium produced, there are 20 tons of magnesium slag and 10 tons of slag. Since there is no feasible way of harmless treatment and reuse of magnesium slag at present, the discharge of solid waste that is higher than the product ratio not only needs to occupy land, but also pollutes air and water sources with wind and rain. The quantity and harm of magnesium slag are a great burden for magnesium production enterprises. In today's society where the voice of environmental protection is getting higher and higher, the treatment and utilization of magnesium slag and the elimination of the pollution caused by magnesium slag to the environment are problems that every magnesium production enterprise must solve as soon as possib...
