Abstract
Microstructure plays a vital role in defining the strength and durability performance of concrete. The study of mechanism taking place at a nanoscale especially the hydrated cement paste helps to engineer the concrete in a well-defined and systematic way. This helps in improving the microstructural properties of concrete in the interfacial transitional zone. Nanoparticles also densify the concrete by occupying the spaces between the cement particles. This reduces the porosity of the cement paste. Nanoparticles are usually added in small amounts about 1-2% of the cement content in concrete. The shape and amount of nanoparticles can be tailored in order to optimize the performance of concrete to suit various projects. This paper reports the state of the art in use of nanoparticles in concrete.
