This paper presents the laboratory investigations of the research work carried out for the precast concrete pipe production plant to identify optimum mix proportions for the production of high early strength concrete without steam curing. Compressive strength, workability and water demandM.Kishore Kumar...
The concrete material has the characteristics of quick coagulation and hardening, high early strength, good erosion resistance and the like, and can be widely applied to the quick repairing in projects or structures such as railways, airfields, bridges, harbors and docks and the quick ...

silica fume is used. Also, these high early strength values are obtained without any need to include a chemical accelerator. This is of interest as such products usually increase the strength development but have a negative effect of the fresh concrete rheology, and especially the slump retention...
high early strength concrete because many proprietary binder systems often perform unpredictably under various construction conditions. For example, reduced freezing-and-thawing resistance was found in some very high early strength concrete mixtures. Meanwhile, early age cracking, associated with autogenous ...
