Abstract
Methods of improving the flow properties of one or more dry particulate cementitious materials are provided. The methods are basically comprised of dry-blending a particulate flow enhancing additive comprised of a particulate solid adsorbent material having a flow inducing polar molecule producing chemical adsorbed thereon with said cementitious materials.
Claims9
A particulate flow enhancing additive for improving the flow properties of dry particulate cementitious materials consisting essentially of a particulate solid adsorbent material having a flow inducing chemical adsorbed thereon;
- wherein said flow inducing chemical is selected from the group consisting of polar molecule producing organic acids, salts of organic acids and acid anhydrides;
- and
- wherein the weight ratio of said particulate solid adsorbent material to said flow inducing chemical is in the range of from about 90:10 to about 10:90.
