(1) The compressive strength of castable precast blocks is high.

This performance is about 2 times higher than that of the conventional product.

(2) The thermal shock resistance is good.

The thermal shock resistance of castable precast blocks can be improved by 8 to 10 times.

(3) Excellent wear resistance.

The wear resistance of the castable precast block is superior to the ultra-low cement castable of the same material.

(4) Saving masonry, curing and baking time.

There’s no need on-site pouring, support and disassembly of molds and construction tools, only on-site installation and combination which is convenient and fast.

(5) It is not subject to the environmental temperature limit.

The castable precast block can be installed in any environment with different temperature range in different countries and seasons worldwide.

(6) Easy to replace and disassemble 

In the actual production, the damaged part of the precast block can be directly replaced, realizing the desire to replace the instant ignition instantly.

(7) Longer shelf life 

Unshaped refractories usually have a shorter shelf life, even in dry conditions, only a few months, while precast blocks greatly extend the shelf life, which is expected to be several years.

(8) Longer service life

Life expectancy is 2 to 3 times longer than ordinary materials, and up to 4 to 6 years, energy saving and environmental protection. The impact resistance is 10 times higher than that of ordinary materials, and the wear resistance is superior to the same level of ultra-low cement material.
