Influence of nanoclay on the behavior of reinforced concrete slabs

Abstract

This study presents experimentally the effect of varying some "material" parameters on the mechanical properties of Concrete. These material parameters were nanoclay content (0%, 2%, 4%, 6%,8%, 10%) weight percent of cement, and polypropylene content (0%, 0.75%, 1.5%,2.25%). The investigated mechanical properties of concrete were compressive strength, splitting tensile strength and Flexural Strength . Significant improvement in the mechanical properties of concrete is observed on using Nanoclay due to its high pozzolanic activity confirming the formation of higher amount of C-S-H gel in the presence of nanoparticles. When Nanoclay was increased from 0% to 8% improves compressive strength, splitting tensile strength for samples with polypropylene 1.5% about 3%, 7%,10%and 12.4% respectively, 4%, 19%,30.6%and 39.4% respectively in Splitting Tensile, and flexural modulus of rupture increased by 6%, 20%,28% and 36% respectively.
