Abstract:

Concrete with the utilization of Nanomaterials enhances its strength & durability, due to which it finds its applicability in the construction industry. The addition of nanomaterials reduces the cement content as cement increases the emission of carbon dioxide, which causes the greenhouse effect. In the present work, cement is replaced with various dosages of nano-silica to understand its influence on the mechanical response of the concrete. Experimental studies were conducted by varying the dosage of nano-silica as a partial substitution for cement for high-strength concrete mixes. From the experimental studies, it can be observed that 3% was the optimum dosage of replacement of nano-silica. Beyond 3%, the results corresponding to the mechanical properties are not promising. The experimental results are studied, discussed, and presented.

Keywords:

High strength concrete, Mechanical Properties, Nano silica Concrete, Nano Materials, Optimum dosage.
