Study on the Performance of a Novel Shrinkage Reducing Admixtures (SHSRA) of Concrete

Abstract:

Article Preview

A novel Shrinkage reducing admixture (SHSRA) has been developed. Several tests including the workability , drying shrinkage,the hydration heat and strength tests were carried out to evaluate the effect of SHSRA on the performance of the concrete specimens. The results showed that the presence of SHSRA induced a significant reduction in dry shrinkage by up to 40% after 28 days. The SHSRA could cause decreases in both hydration rate and heat release of hydration of cementing materials which can attribute to reducing the risk of cracking. Besides, no negative side effect on the concrete workability and the later strength has been observed with the addition of the SHSRA.
