Non-plastic hydraulic cement mixes and process for improving such mixes |
摘要 |
A method is provided for improving the strength and other properties of non-plastic dry hydraulic cement mixes, such as the dry concrete mixes used for making concrete masonry units. The method comprises incorporating a synergistic combination of two additives into the cement mix. The first additive is a salified methyl or ethyl substituted benzene or naphthalene sulfonate, and is preferably added in an amount of between about 0.01 and 1%, by weight based upon the weight of the cement. The second additive is a tertiary aliphatic amine oxide, and is preferably added in an amount of between 0.001 and 0.1%.
