ABSTRACT:
This invention provides cementiferous compositions having improved flow characterisitics which are given by the incorporation of certain hydroxy acrylate copolymers. Typical copolymers are 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.
