CEMENTIFEROUS COMPOSITIONS |
摘要 |
This invention provides cementiferous compositions having improved flow characteristics which are given by the incorporation of certain hydroxy estercopolymers. The copolymers include those of acrylic or methacrylic acid with a hydroxyalkyl acrylate or methacrylate and are used preferably in the range 0.01% to 2.5% w/w on the cement in the cementiferous composition. This invention also provides novel additive compositions for use in the cementiferous compositions which, in addition to the copolymer, also contain an anti-foaming agent. |
