Evaluation of curing condition on the high Strength concrete durability: Bangladesh perspective

Abstract:

This study measure the curing condition on the high Strength concrete durability in Bangladesh. In the industry of  construction, HPC (High Performance Concrete) has important role for improving durability and improved strength over ordinary concrete. Appropriate concrete compaction is essential for ensuring durability and strength of concrete. Entrapped air expels can placed concrete freshly and set the combined particles collectively that can increase the concrete density. Alike, concrete cover should maintain properly from environmental effects that can protect reinforcement such as deterioration and affords thermal insulation. concrete Durability refers to the ability of concrete to oppose abrasion, chemical attack and weathering action whereas maintaining its preferred civil engineering properties. This study observed that concrete made by clean water and under normal curing condition showed low permeability and Concrete mode by clean water and used within 2 hours showed moderate permeability. This study also showed than Concrete mode with polluted water gave high permeability. The present study will assist civil engineers and supervisors to know the impact of curing condition on the performance concrete durability.
