Latex Modified Concrete for Development of Sustainable Architecture

Abstract

To improve the performance of concrete, latex polymer and fly ash are mixed with concrete. This paper presents the effects of using additive material styrene-butadiene rubber (SBR) Latex and Admixture Fly Ash as a partial replacement to cement in mortar mixes. In this research comparison between with or without the replacement of fly ash and polymer is studied for Compressive strength, split tensile strength, flexural strength and ultrasonic pulse velocity test (NDT). This work based on an experimental study of mortar made with Mix proportioning M-25 concrete accordance with IS 10262: 2009 with OPC (Ordinary Portland Cement). The first mix (M₀) was prepared with 100% cement content and no additive material such as polymer cannot be added in concrete and remaining specimens were prepared M_1, M₂ and M₃ with additive material SBR Latex polymer of fixed volume of 15% by weight of cementitious material were used and 10%, 20% and 30% of OPC replaced by Fly Ash according to mix design by Indian Standard Method. The effect of the polymer- binder ratio and fly ash content on the properties of Polymer modified concrete (PMC) was examined, the 7 days and 28 days of the age of curing.

It is concluded from the test results the compressive strength of PMC decreases with increasing fly ash content and fixed 15 % polymer content. The split tensile strength of PMC increasing the M₂ mix designation of 20% Fly ash and fixed 15% polymer of the strength will be increasing respectively. The flexural strength of PMC increasing the M₃ mix designation of 30% Fly ash and 15% polymer of the strength will be increasing respectively. Ultrasonic pulse velocity test (NDT) of PMC the compressive strength and young modulus decreases with increasing fly ash content and fixed 15 % polymer content and pulse velocity increases with increasing fly ash content and fixed 15 % polymer content at 28 days the age of curing.

In this investigation, observed all result the increasing the age of curing, strength will be increasing respectively. It is lightweight as compared to normal concrete.
