Early Age Properties of High-Performance Concrete

High Performance Concrete is used to not only minimize the environmental footprint of cement and concrete industry, but also enable design rapid construction taller more slender structures. Despite significant change in property requirements, properties as during structures are mostly still based on 28-day water cured compressive strength, stiffness, long term drying shrinkage creep. The relevance these measured actual behaviour structure should be questioned high strength known have low water/cement ratios resulting early age shrinkage, which currently taken into account by designers. This paper a study where was investigated, with specific focus first 24 hours after casting. effect factors such ratio, admixtures, ambient material temperatures, shutter type cast volume setting time, development stiffness studied observed trends discussed this paper.
