Shrinkage-reducing admixture (SRA) is a mitigation strategy against autogenous shrinkage in high-strength concrete (HSC). It acts by reducing the surface tension of the fluid in the pore system of the cement paste. An experimental program was carried out to investigate the influence of SRA on concrete durability, as few studies about this subject have been developed. Its effectiveness in reducing autogenous shrinkage and its influence on compressive strength were also evaluated. The results… CONTINUE READING
