Abstract

The invention discloses a high-strength corrosion-resistant cement brick and a making method thereof and relates to the technical field of building materials. The cement brick comprises the followingraw materials in parts by weight: 40-60 parts of cement, 24-36 parts of medium sand, 20-35 parts of a modified glass fiber, 15-25 parts of white clay, 12-20 parts of blast furnace slag, 6-10 parts ofa gelatinizing agent, 8-16 parts of calcium stearate, 4-10 parts of lecithin, 4-10 parts of aids and 1-3 parts of sulfur trioxide. The making method of the cement brick comprises steps of mixing, stirring, sintering and maintenance. The cement brick has very high strength and good corrosion resistance, and is long in service life and applicable to large-scale application.

Description

technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to a high-strength corrosion-resistant cement brick and a preparation method thereof. Background technique [0002] At present, cement bricks on the market generally have problems such as low strength and poor corrosion resistance, which are easy to break and damage during use. Moreover, after cement bricks are used in long-term acidic or alkaline conditions, the corrosion is serious, the strength loss rate is high, and the service life is high. short. [0003] The Chinese invention patent application with publication number CN107954700A discloses a corrosion-resistant corundum refractory brick and a preparation method thereof. The invention comprises a refractory brick base and a high-temperature resistant coating sprayed on the surface of the refractory brick base; wherein, the refractory brick The preparation raw materials of the brick matrix include: corun...
