Patent number: 8815009Abstract: The present invention provides a method for making sand compositions wherein manufactured sand particles are pretreated with a clay-mitigating polycation and blended with natural sand particles that have washed to remove fines such that at least 90% of the natural sand particles are retained on a 75 micron sieve. Methods of the invention also involve the use of the blended pretreated sand for making concrete wherein the sand is combined with cement, a polycarboxylate type dispersant, a further amount of clay-mitigating polycation compound, and at least one hydryoxyl or hydroxyl carboxylic acid or salt compound.Type: GrantFiled: October 17, 2011Date of Patent: August 26, 2014Assignee: W. R. Grace & Co.-Conn.Inventors: Arthur Kyriazis, Bruce Perry, Eric Koehler, Leon Bablouzian
