This paper discusses the efficiency of using finite-element modelling, based on the isothermal calorimetry results, for predicting early-age temperature development of in situ concrete. In addition, this work quantifies the beneficial effect of using ground granulated blast-furnace slag as a partial replacement of cement in structural concrete.
The study concluded that compressive strength of concrete improved almost all the % replacements of normal crushed coarse aggregate with crystallized slag by 5% to 7%. In case of replacements of fine aggregate and both type of aggregates, the strength improvements were notably noticed at 30% to 50% replacement level.
cement of 43grade cement confirming to Is:8112-1989 is used and the specific gravity of cement is 3.15 and locally available sand is used as fine aggregate and coarse aggregate of 12.5mm size are used and also ground granulated furnace slag is used as replacement material for cement and poly propylene
granulated blast furnace slag is better replacement of cement than various other alternatives. The rateof strength gain in slag replaced concrete is slow in early stages but with proper curing the strength goes on increasing tremendously. The compressive strength decreases when the cement replacement is more than 50%. Use of slag or
