As the name suggests, low-cement castables are castables with low cement content, low cement dosage, and small calcium content. The lower the calcium content, the lower the pores and the stronger the erosion resistance. Low-cement castables are divided into low-cement castables such as aluminum silicate, mullite, corundum, magnesia-aluminum, fine stone, carbon, and silicon carbide. Low … Read more
