Multipurpose, cement dispersing polymers for high flow and high strength concrete |
摘要 |
<p>A new category of multi-purpose polymers is presented, said polymers being capable to serve as a cement dispersing agent and which at the same time are set-accelerating and do have shrinkage reducing- and anticorrosive properties to steel. Said polymers are ester-and amidgroup-modified acrylic polymers, obtainable by a polymer analogous esterification of a polyacrylic acid with 1) a monofunctional polyalkyleneglycol-monoalkylether, 2) a tertiary alkanolamine and optionally 3) by amidation with a amino-polyalkylenglycol alkylether. Said multi-purpose polymers serve for cement dispersing admixture for concrete with set accelerating, shrinkage compensating- and anticorrosive properties to steel.</p> |
