<p>The present fiber reinforced cellular concrete is produced through a chemical reaction that does not require high heat or pressure ovens (autoclaves). Among its unique features, is the fact that different compression strengths can be obtained by varying the proportion of ingredients and resulting densities. The concrete utilizes a base of a pozzolanic product with aluminium powder, lime, calcium formate, cement, and polypropylene fiber is added, along with water. Expandable shale, clay or slate is added to provide lower shrinkage to the resulting mass reducing cracking. Optionally, sand and compatible reinforcing material can also added.</p> |
