Problems solved by technology

This method produces finished filling materials. The finished filling materials are characterized by low strength. General industrial waste can realize the filling function after treatment, which has no practical significance.
The impact of alkaline substances (calcium oxide, magnesium hydroxide, etc.) in alkali slag on the strength of building materials is not solved
[0007] Due to the high moisture content and strong cohesiveness of alkali slag, the use of alkali slag to prepare artificial stone, artificial stone products and light aggregates is still in a blank area, and no relevant reports have been found on the use of alkali slag to manufacture artificial stone.

Embodiment 1

[0037] The invention discloses a formula and a method for manufacturing artificial stone or artificial stone products by using alkali slag. The artificial stone or artificial stone products include imitation granite, imitation marble, imitation quartz stone, sidewalk boards, curb stones and other artificial stones and their products.

[0038] The content of each component of the artificial stone or artificial stone product formula is (mixing ratio): 30-60% of alkali slag, 10-50% of fly ash, 5-30% of granulated blast furnace slag powder, and 5-15% of cementitious material %, aggregate 0-40%.

[0039] Wherein, the moisture content of the alkali slag is 40-70%, and the formula may also include 0.01%-2% of pigment.

[0040] The granulated blast furnace slag powder is a molten material mainly composed of silicate and aluminosilicate obtained during blast furnace smelting pig iron, which is granulated blast furnace slag powder after being quenched and granulated and ground.

Abstract

The invention discloses a formula for preparing a building material product by utilizing caustic sludge, coal ash and pulverized blast furnace slag powder, and particularly relates to a formula for preparing an artificial stone and an artificial stone product, and a formula for preparing lightweight aggregate and two formulas for preparing road foundation materials. The formula comprises caustic sludge, coal ash, a gelling material, a granulated blast furnace slag powder, aggregates, pigment, amino resin or acrylic resin. The prepared artificial stone, the lightweight aggregate and the road foundation material have the advantages of high strength and no fracturing. The artificial stone and the artificial stone product are high in simulation degree and low in cost, the preparation process is simple in operation, a complicated process such as burning and evaporating is not needed, the wastes are uniformly mixed and solidified to form the product, the resource is adequately utilized, the energy is saved, industrialized production is convenient, and the cost is low. The economical value is good.

Description

technical field [0001] The invention relates to the field of building materials, in particular to formulas for preparing artificial stone and artificial stone products, light aggregates and roadbed materials by using alkali slag. Background technique [0002] As an important chemical raw material, soda ash is widely used in various industries. At present, the output of soda ash in the world is about 30 million tons, of which, the soda ash produced by the ammonia-soda method is about 20 million tons. A large amount of white precipitate is produced, which is the soda industrial waste residue, commonly known as "white mud", also known as alkali slag. The world produces nearly 20 million tons of alkali slag every year. [0003] The composition of alkali slag is not exactly the same. According to reports, the main components of alkali slag are: calcium carbonate 39.5%-60%, calcium sulfate 2.8%-20%, calcium chloride 9.8%-14.0, sodium chloride 2.4%-8.0% , calcium oxide 3.0%-8.3%,...
