LIGHTWEIGHT CEMENTITIOUS MATERIAL AND METHOD OF MAKING

摘要

A lightweight cementitious material is produced by combining concrete mixture, non-ionic surfactant and water in a mixture. The concrete mixture includes cement and aggregate materials. The mixture is mixed allowing the cement to be naturally hydrated thereby increasing the temperature of the mixture. The increase in temperature causes the surfactant to reach its cloudpoint resulting in the surfactant foaming and dropping out of solution. The surfactant bubbles produced during the foaming are incorporated in the voids between the cement and the aggregate materials. The mixture cures to a desired hardness and the result is a lightweight concrete material.
