In the present study, quaternary blended concrete developed by replacing cement partially with the industrial waste such as vetrified tiles powder, silica fume and fly ash was reinforced with multi walled carbon nano tubes (MWCNT) at dosage rate of 0.01, 0.02, 0.03, 0.05 and 0.1 % by weight of cementitious material. The quaternary blended concrete with and without reinforcement were subjected to the compressive, flexural and split tensile strength tests. The obtained results for both types of mixes were compared and inferences were drawn. The observed compressive strength values for the mix reinforced with MWCNT was found to increase by 12, 16, 21 and 32 % up to the MWCNT dosage of 0.05 % at 28 days of curing age in comparison to the unreinforced quaternary blended concrete. The compressive strength at 0.1 % dosage of MWCNT decreased at all curing ages. When compared with the mixes reinforced with MWCNT, it was observed that there is an increase of about 32 % in compressive strength at 28 days. It was also inferred that the mixes with MWCNTs up to the dosage rate of 0.05 %, the strength increased from 6.10 to 7.25 MPa for 7 days curing age and from 6.83 to 8.95 MPa for 28 days of curing period. There was an observed increase up to 31 % for the reinforced mix in relative to the quaternary blended concrete pertaining to the flexural strength and an increase of 40 % in case split tensile strength up to 0.05 % dosage 28 days of curing period. It is concluded that the blended concrete mix reinforced with a dosage rate of 0.05 % with MWCNTs serves to be optimum reinforced quaternary blended concrete which can be utilized for the construction activities owing to the improved flexural and tensile strengths developed.
