STUDY ON COMPRESSIVE STRENGTH AND INTERNAL ORGANIZATION WITH BINDER USING LOW-HEAT PORTLAND CEMENT AND SILICA FUME

The compressive strength and internal organization of the heat curing test piece and 20℃ seal curing test piece that made with the high strength mortar using the low heat portland cement and silica fume were confirmed. As a result, the compressive strength of the heat curing test piece at three days is almost equal to that of the 20℃ seal curing at 91 days. As a result of an internal analysis, the pore size distribution curve and the amount of the calcium hydroxide of the heat curing test piece at three days was almost equal to that of 20℃ seal curing at 91 days.
