1. An Experimental Study of the Mechanical Properties of Glass Fiber Reinforced High Strength Concrete Partially Replacing Cement with Nano Silica by Pathan Sameer Khan et.al. The studies were conducted on the compressive, flexural and tensile strengths of concrete by varying the percentage of fiber from 0% to 1% by weight of concrete at constant 2% Nano silica in cement. The obtained results were then compared with M40 conventional concrete. It was observed that the compressive, flexure and tensile strength is increased with the increase in fiber content up to 0.5-0.75% thereby indicating that 0.75% is the optimal fiber content. An increase of 17%, 42% and 54% over M40 conventional concrete were registered for compressive, flexure and split tensile strengths respectively.

2. Durability Study on Nano Concrete by P Vasanthi et.al. The purpose of this experiment was to determine the effects of addition of nano silica to the concrete mix. The test results have shown that the M40 grade of concrete mixed with 2% of Nano silica tested in acidic and alkali condition. The compression strength for 14, 21 & 28days is 28.7, 37.33 & 41.8N/mm2respectively. With addition of 2% of Nano silica in acidic condition, it has been found that compressive strength has increased to 33.05, 42.92 & 48.07N/mm2 for 14, 21 & 28days respectively. In alkali condition, it has been found that compressive strength has increased to 37.70, 46.09 & 51.36N/mm2 for 14, 21 & 28days respectively. Hence it has been proven that addition of Nano silica to the concrete mix results in an increase in the compressive strength and durability when compared to the ordinary concrete mix.

3.Performance on the study of Nano Materials for the Development of Sustainable Concrete by S Sanju, et.al. This paper is about, to study the effect of incorporating nano particles such as Nano Al2O3, Nano Fe2O3 and Nano SiO2 on mechanical and durability properties of concrete. Nano particles were added in three different dosages of 0.5%, 1% and 1.5% of weight of the Cementitious material into the concrete mixture. In the experimental evaluation of strength properties of nano modified concrete with addition of nano particles, it has been found that the compressive strength increased to a maximum value of 54.6% and 57.6% with 1.5% addition of Nano SiO2 and binary combination of NSF respectively with respect to control specimen. The split tensile strength increased to a maximum value of 76.8% for NSF and 58.8% for NS3 with respect to control mix.

4. Hair Fiber Reinforced Concrete by Jain D. et.al. The experiments were conducted on concrete beams and cubes with various percentages of human hair fiber i.e. 0%, 1%, 1.5%, 2%, 2.5% and 3% by weight of cement. For each combination of proportions of concrete one beam and three cubes are tested for their mechanical properties. By testing of cubes and beams we found that there is an increment in the various properties and strength of concrete by the addition of human hair as fiber reinforcement. 2 April 2019
