Embodiment Construction

[0017] The industrial waste slag produced in the process of magnesium smelting mainly includes reducing slag, slag and stone powder, which contain relatively high silicon oxide, calcium oxide and aluminum oxide. These industrial wastes are the main raw materials for producing the concrete block bricks of the present invention. Reduction slag is the waste left after the metal magnesium is extracted in the reduction process, and it contains more calcium oxide, which combines with water to form calcium hydroxide, which is the reactant for the preparation of concrete block bricks. Slag is the ashes of raw coal combustion, which mainly plays the role of providing silica in the reaction process of preparing concrete block bricks. Stone powder is sand and stone discarded after screening dolomite. It is a kind of fine aggregate, which mainly plays the role of increasing the strength of block bricks. In addition, the present invention utilizes magnesium smelting waste slag to prepare ...

Abstract

The invention provides a concrete brick which is prepared by utilizing magnesium residues and a preparation method thereof. The raw materials of the concrete brick accounted by the weight percentage comprise: 20 to 30 percent of reduced slag, 5 to 10 percent of cinder, 10 to 15 percent of stone powder, 8 to 12 percent of cement, 30 to 40 percent of crushed stone and 10 to 15 percent of water. As the invention utilizes the magnesium residues to prepare the concrete bricks, which not only reduces the discharge amount of residues, protects the environment, and saves the energy, but also has simple manufacturing method and low manufacturing cost.

Description

technical field [0001] The invention relates to a building material, in particular to a concrete block brick prepared by utilizing magnesium smelting waste slag and a preparation method thereof. Background technique [0002] During the silicon thermal magnesium smelting process, a large amount of solid waste is always produced, and about seven tons of waste slag are discharged for every ton of magnesium metal produced. Environmental protection brings huge pressure, but also brings a certain burden to the operation of enterprises. [0003] The use of industrial waste slag to prepare concrete block bricks can not only reduce pollution discharge, improve environmental protection conditions, but also turn waste into treasure to obtain considerable economic income. At the same time, the product has reliable quality and multiple functions, which can greatly improve the living conditions of the people. It can be vigorously promoted to replace fired clay bricks, which can protect c...
