Mechanical Properties and Durability of Concrete Doped with Nano-CaCO3
Herein, cementitious material was doped with nano-CaCO3 in order to examine its impact on the mechanical, shrinkage and durability of concrete. The performance of plain concrete (PC) was compared with four concretes by varying the nano-CaCO3 contents. Favorable mechanical properties and durability of concrete resulted when the concrete was doped with an appropriate amount of nano-CaCO3 while the mechanical properties and durability of the concrete was weekend in the excess of nano-CaCO3. The detailed analysis revealed that the compactness of concrete with nanoparticles was significantly higher than that of PC, while an excess of nano-CaCO3 would result in the local relaxation and expansion of concrete. Additionally, nanoCaCO3 increased the dry shrinkage of the concrete and the shrinkage ratio of nano-concretes at different ages were higher than those of PCs.
