Abstract
The invention is a cement, water containing composition containing an organic polyglycoside. The composition has at least one of an increased air entraining capacity, a reduced viscosity and a retarded setting time.
Claims17
A hydraulic cement composition comprising water;
- hydraulic cement;
- and from about 0.001% to about 3.0% by weight of the cement of an organic polyglycoside of the formula ##STR5## wherein R is an organic radical having from about 6 to about 22 carbon atoms which can be aliphatic, cyclic or aromatic, saturated or unsaturated, R.sup.1 is H, or an alkyl group containing 1 or 2 carbon atoms, G is a residue of a reducing sugar and x is a number of from about 1.0 to about 5 and y is a number of from 0 to 5.
A method for affecting at least one property of an aqueous cement containing composition selected from the group consisting of setting time, air entrainment and slump which comprises adding to the cement containing composition from about 0.001% to about 3.0% by weight of cement of an organic polyglycoside of the formula ##STR6## wherein R is an organic radical having from about 6 to about 22 carbon atoms which can be aliphatic, cyclic or aromatic, saturated or unsaturated, R.sup.1 is H, or an alkyl group containing 1 or 2 carbon atoms, G is a residue of a reducing sugar and x is a number of from about 1.0 to about 5 and y is number of from 0 to 5.
