Moderate heat anti-crack type Portland cement
The invention discloses moderate heat anti-crack type Portland cement. The moderate heat anti-crack type Portland cement is characterized in that cement clinker of the moderate heat anti-crack type Portland cement comprises the following mineral components in weight percent: 20-30% of tricalcium silicate, 40-60% of dicalcium silicate, 7-11% of tricalcium aluminate, 5-10% of tetra calcium aluminoferrite and 1-8% of free calcium oxide, wherein the content of magnesium oxide in the cement is 0.5-1.0%, the alkali content is not more than 0.5%, the content of sulfur trioxide is not more than 2.0%, and all the percents are weight percents. The moderate heat anti-crack type Portland cement can obviously improve the crack resistance of hydraulic concrete.
