CEMENT MIXTURES AND METHODS OF PRODUCTION

Abstract

The production refers to a cement mixture in which the long-term strength of the mortar is very good even when the MgO content in Portland cement is high; and a method of producing a cement mixture in which the long-term strength of the mortar can be improved even when the MgO content in Portland cement is high. The cement mixture consists of Portland cement meeting the conditions (1) and (2) below; and 0.001 to 0.025 parts by weight of alkanolamine compared to 100 parts by weight of Portland cement. (1) 0.55 < MgO / Fe3O3 + Cl / SOa / SCh < 0.95 (2) 0 < OC4A
