The advantages listed are higher strength concrete that uses less additives and cement. Disadvantages include limited availability and means to produce nano materials currently. In conclusion, well dispersed nano particles can increase concrete viscosity, strength, and bond between cement and aggregates. Read less

Change in Ph value The pH of the fresh cement paste is at least 12.5. The atmospheric carbon dioxide diffuses into the hardened concrete through pores and when carbonation reaction takes place, the alkalinity of the concrete reduces. The pH of a fully carbonated paste is about 7. Means in carbonated zone the Ph range below 9.2.

4. DEFINITION – Self healing concrete is a concrete which heals itself when it comes in contact with air and water, it produces lime on outer layer of concrete. * In most of the traditional concrete mixtures 20-30% of the cement is left unhydrated. * If cracking of the concrete occurs, unreacted cement grains may become exposed to moisture penetrating the crack.
