A method of preparing a particulate flow enhancing additive for improving the flow properties of particulate cementitious materials comprising adsorbing a flow inducing chemical on a particulate solid adsorbent material.
A method of preparing a particulate flow enhancing additive for improving the flow properties of particulate cementitious materials comprising adsorbing a flow inducing chemical selected from the group consisting of polar molecule producing organic acids, salts of organic acids and acid anhydrides on a particulate solid adsorbent material selected from the group consisting of precipitated silica, zeolite, talcum, diatomaceous earth and fuller's earth.
A method of preparing a particulate flow enhancing additive for improving the flow properties of particulate cementitious materials comprising adsorbing a flow inducing chemical selected from the group consisting of polar molecule producing organic acids, salts of organic acids and acid anhydrides on a particulate solid adsorbent material selected from the group consisting of precipitated silica, zeolite, talcum, diatomaceous earth and fuller's earth, wherein the weight ratio of said particulate solid adsorbent material to said flow inducing chemical adsorbed thereon is in the range of from about 90:10 to about 10:90.
