General purpose Portland cement based ultra-light physical foamed concrete
The invention discloses general purpose Portland cement based ultra-light physical foamed concrete which is characterized by being prepared by mixing, forming and maintaining the following components in percentage by weight: 20-70% of general purpose Portland cement, 0-40% of a type A admixture or/and 0-40% of a type B admixture, 0.5-4% of a type C additive, 0.3-2% of a foaming agent, 0-1% of a water reducing agent, 0-4% of fibers and 25-60% of water. The general purpose Portland cement based ultra-light physical foamed concrete disclosed by the invention has the characteristics of ultra-low dry density, low thermal conductivity, relatively high strength, wide raw material source, low cost, simple preparation process, easy maintenance process selection and the like, is suitable to serve as an earthquake-proof and energy-absorbing material, a lightweight cushion course and a catalyst carrier material in a thermal insulation project, a floor heating project and a back filling project, and is particularly suitable for a building exterior wall external thermal insulation system, a roof thermal insulation system, a composite thermal insulation wall body and a buffer energy absorbing system.
