Abstract

An extrudable cement-based material is formed from a mixture that includes cement in the range of about 40 to 90% by wet weight percent, a lightweight expanded aggregate in the range of about 10 to 60% by wet weight percent, a secondary material in the range of about 0.1 to 50% by wet weight percent, a reinforcement fiber in the range of about 1 to 20% by wet weight percent, a rheology modifying agent in the range of about 0.5 to 10% by wet weight percent, a retarder in the range of about 0.1 to 8% by wet weight percent, and water in the range of 10 to 60% of a total wet material weight.
