Decreasing the water demand can improve strength by decreasing the water-to-cement ratio for a given workability. The narrow PSD cements are well suited for making blended cements, including binary, ternary and quaternary blends.Type: GrantFiled: March 13, 2013Date of Patent: October 8, 2013Assignee: Roman Cement LLCInventors: John M.
