Cementitious compositions |
| abstract |
In a first aspect, a ready mixed composition comprises: a cementitious material, e.g. calcium sulphate hemihydrate; water; and a retarder comprising a copolymer having units of the formula: where x and y are integers and may be the same or different or an ionised form thereof.. In a second aspect the retarder comprises a rosin modified maleic anhydride polymer or copolymer or an ionised form thereof. In a third aspect the retarder comprises a copolymer of having units of the formula: wherein R is C4H9 or (CH3)2CH, or an ionised form thereof. In a fourth aspect the retarder comprises 0.09 to 0.1% bv weiaht plaster of a copolymer havino units of the formula: and having a molecular weight in the range of about 110 000 to about 140 000, or an ionised form thereof. A ready mixed coating system comprises a composition as described above and a setting accelerator. |
