High Alumina Andalusite Anchor Refractory Brick for Heating Furnace
The Description:
Anchor brick is a kind of high-strength material, which is mainly used for structural support of kiln, construction and other projects, and as a supporting layer of foundation and pavement. It is made from a mixture of cement, mineral particles, aggregates and other additives and is popular due to its high compression resistance and weight. Compared with concrete, anchored bricks have lower density and higher strength, so they can withstand greater loads. In addition, the anchor brick also has the characteristics of water resistance, frost resistance, weather resistance, etc., so it is a high-performance material widely used in construction and Bridges.
