摘要:
A lightweight thermal insulating cement-based material is formed from a mixture that includes cement, water and a foaming agent. The foaming agent can be an aluminum powder or a surfactant. The insulating material has a maximum use temperature of about 900 degrees Celsius or more.
摘要:
An extrudable cement-based material formed from a mixture that includes cement, water, gypsum, secondary materials, reinforcement fibers and rheology modifying agent. The extrudable cement-based material is a lightweight material that has a density in the range of about 1.4 to 2.4 g/cm3, a compressive strength in the range of about 5 to 100 MPa, and a flexural strength in the range of about 5 to 35 MPa. Note that the cement may contain gypsum such that the gypsum is not added to the mixture.

摘要:
An expanded lightweight aggregate has compositional ranges (Wt. % Range) of about: (a) 40 to 60% ground glass or pumice, 40 to 60% water, 3 to 15% sodium silicate, and 0.1 to 5% NaNO3 for the slurry; and (b) 50 to 85% ground glass or pumice, and 15 to 50% slurry for the granulator.

摘要:
A high temperature lightweight thermal insulating material is formed from a mixture that includes cement or silica sand, water and a foaming agent. The foaming agent can be an aluminum powder or a surfactant. The insulating material has a maximum use temperature greater than about 600 degrees Celsius.
