Effect of Steam Curing on Initial Strength Development of Mortar
Effect of Steam Curing on Initial Strength Development of Mortar is a scholarly work, published in 2017 in ''International Journal of Engineering and Technology''. The main subjects of the publication include fiber-reinforced concrete, composite material, geopolymer, mortar, curing, and materials science. The steam curing process is being applied to produce precast concrete to accelerate production cycle.A prediction of initial strength is required to determine optimized production cycle and provide economical mix proportions.As for this, the strength estimate by the Maturity method is being used widely so far.However, this method is pointed that the accuracy of the estimated strength of the concrete which has been steam cured is low.This is one of the problems on the precast concrete production.In this study, the relationship between initial strength at early age and effective material age calculated by Maturity method and Arrhenius's law was evaluated.As a result, it showed a higher estimation accuracy of the Arrhenius's law than the Maturity method.However, the accuracy of the prediction was different in each condition such as cement type, water-cement ratio, and steam curing temperature and material age.
