Abstract

Self-Compacting Concrete (SCC) is an innovative concrete which firstly, developed in Japan. This type of concrete has an ability to flow under its own weight to fill formwork completely and does not require vibration for placing and compaction. This research studies the effects of percentages of fly ash as a part of cement replacement in concrete mixture and curing temperature to strengthten the development of concrete. The fly ash was taken from PT IMIP industry Morowali. The percentage of fly ash to replace cement in concrete mixtures are 0, 10, 15 and 20% by weight of cementitious materials. The curing temperatures are set to room temperature, 30, 40 and 50℃. The results show that the optimum percentage of fly ash to replace cement in concrete mixture is 15%; which is lower than that of generally used in researches conducted other countries (25 – 30%). This is caused the used cement in concrete mixtures is PCC, which has already mixed with fly ash in clinker in cement producing process. The results also show that the higher curing temperature result the higher strength of concrete at early ages. This proves that the curing temperature affect the strength of concrete as the curing temperature increase the activation energy of concrete and accelerates the cement hydration process. This increases strength of concrete at early ages.
