Abstract
An improved composite material is prepared by first uniformly mixing cement and perlite fines. The perlite fines comprise particles that are less than 200 mesh. The mixture of perlite fines and cement is then mixed with water, formed into a desired shaped, and allowed to dry. The dried material is useful in many applications where cement is used and has fireproofing and strength characteristics superior to ordinary concrete.
