Abstract

Early deformation cracking is a widespread problem in base concrete walls of high-rise building. In the view of material to solve concrete cracking at early age, new-anti cracking functional materials make it by reducing shrinkage and regulating hydration heat. In this paper, several groups of concrete members were designed to contrast the effect of the functional materials, and based on embedding sensors in concrete members, temperature evolutions and strain evolutions are obtained in outdoor. The results show that compared with reference concrete, the maximum temperature rise of concrete prepared with new-anti cracking functional materials not only was reduced, but only there are reasonably expansive deformation at early age which can compensate later shrinkage which will be very beneficial to inhibit cracking.
