Low and Ultra-Low Cement Castables

Low and ultra-low Cement Castables have the characteristics of small pore size, large density, good volume stability, high strength, and a small amount of water. They overcome the characteristics that the strength of ordinary castables decreases significantly at 800~1200 ℃, increases with the increase of temperature, and have excellent thermal shock resistance, slag resistance, and corrosion resistance.

Physical and chemical indicators

Low and ultra-low cement castables features

High refractoriness, high temperature, and low-temperature resistance
Erosion resistance, impact resistance, high wear resistance, high strength
Strong plasticity, can be cast into any shape
Good air tightness, can reduce heat loss and save energy

How to use castables？

Castables are generally poured and formed by on-site pouring, vibration, or tamping during use, and can also be made into prefabricated parts for use.

Low and ultra-low cement castables advantage

Low and ultra-low cement castables have strong cohesive force, long initial setting time and construction operation time, fast strength growth, strong impermeability, no need for acid treatment, easy to ensure the compactness of masonry ash gaps, and can significantly improve the blast furnace lining The airtightness of the wall, and the anti-corrosion ability of the lining.

Scope of application of castables

Low and ultra-low cement castables can be used in the steel industry, petrochemical industry, metallurgical industry, and power plant industry, with wide application and little restriction.
