[Al.sub.2][O.sub.3] and [Fe.sub.3][O.sub.4] released from slag are used in increasing the (Al + Fe)/Ca ratio of the C-S-H formed from the OPC; some probably enters additional AFm or hydrogarnet
The calcium aluminate is as soluble as the C3S and it reacts rapidly to form a mineral called hydrogarnet

Where C is calcite, Q is quartz, and CH is calcium hydroxide, the test result helps confirming the effects on the compressive strength and the shrinkage especially in the case of SRA + EX + FA, of which the calcium hydroxide is highly found as well as [C.sub.3]A[H.sub.6] which derives from the aluminate reaction of [C.sub.3]A at higher than 60[degrees]C, resulting in the hydrogarnet
