Embodiment 1

[0022] A method for preparing hollow bricks using slag to enhance frost resistance, comprising the following steps:

[0023] (1) Gneiss, slag and iron ore powder are added to the grinder for crushing and grinding, and then sieved to obtain a premix, and the mixing mass ratio of the gneiss, slag and iron ore powder is 10: 80:1.2, the grinding process is to mix gneiss, slag and iron ore powder, then add glycerin with 30% of the mass of slag, grind for 2 hours, and then add an organic acid solution with 0.5% of the mass of glycerol , continue to grind for 2 hours, then rotate to evaporate and dry, filter, and dry to obtain that, the organic acid solution is selected from one of C1-C18 organic carboxylic acids, wherein the organic carboxylic acid solution is 1.5% by mass fraction Oxalic acid solution, by adding a certain amount of glycerol and organic carboxylic acid as grinding aids when grinding gneiss, slag and iron ore powder, can greatly improve the grinding effect and promot...

Abstract

The invention discloses a hollow brick production method utilizing furnace slag to enhancing the anti-freezing performance, and relates to the technical field of hollow brick production. The production method comprises the following steps: (1) preparing a premix; (2) preparing an intermediate; (3) preparing a calcined material; (4) molding by a two-stage vacuum brick extruder; (5) producing a hollow brick dry blank; and (6) producing the formed hollow brick. The hollow brick produced by the method has an excellent anti-freezing performance.

Description

technical field [0001] The invention belongs to the technical field of hollow brick preparation, and in particular relates to a hollow brick preparation method which uses slag to enhance frost resistance. Background technique [0002] Commonly used in non-load-bearing parts, the porosity is equal to or greater than 35% [1], and the bricks with large empty sizes and small quantities are called hollow bricks. Hollow bricks are divided into cement hollow bricks, clay hollow bricks, and gneiss hollow bricks. Hollow brick is the main wall material commonly used in the construction industry. Due to its advantages of light weight and low consumption of raw materials, it has become the first product recommended by the national construction department. Hollow bricks have three forms: single row of square holes, single row of round holes and multiple rows of flat holes, among which multiple rows of flat holes are more beneficial to heat preservation. As a new type of wall, the wall ...
