PURPOSE:To easily lower a heat of hydration and improve strength development by compounding SiO2, Al2, Fe2O3 and CaO at the ratios to make a composition in a specified range. CONSTITUTION:SiO2 is expressed as S, Al2O3 as A, Fe2O3 as F, CaO as C and 3A+2.25F as X. S, A, F and C are compounded as main components. The objective super low exothermic cement clinker is obtained by burning a raw material mixture which has the composition, after burning, in the region confined with the surfaces, etc., of a solid formed by connecting point a (C3S is 10wt.%, X is 20wt.%, C3A/C4AF is 0.576), point b (C3S is 10wt.%, X is 20wt.%, C3A/C4AF is 0.925), point c (C3S is 30wt.%, X is 20wt.%, C3A/C4(AF is 0.576), point d (C3S is 30wt.%, X is 20wt.%, C3A/C4AF is 0.925), point e (C3S is 10wt.%, X is 5wt.%, C3A/C4AF is 0.576), point f (C3S is 10wt.%, X is 5wt.%, C3A/C4AF is 0.925), point g (C3S is 60wt.%, X is 5wt.%, C3A/C4AF is 0.576) and point h (C3S is 60wt.%, X is 5wt.%, C3A/C4AF is 0.925). |
