Abstract

Alkali metal aluminosilicate of the zeolite P type having the oxide formula M.sub.2/n O.Al.sub.2 O.sub.3.(1.80-2.66)SiO.sub.2.yH.sub.2 O, y being the water content, proves to have both excellent Calcium Effective Binding Capacity and Calcium Uptake Rate at temperatures below 25.degree. C. The present invention provides for the use of such a zeolite P as a low temperature calcium binder.
