Effect of FRC Due to Saline Water and Urea Solution

Abstract

Fibre-reinforced cement mortar is a composite material used to introduce short fibre for enhancing some properties of the mortar matrix. Mortar cubes of 1% hybridization by using poly-propylene (PP), coconut coir (CC) and scrap rubber (TR) fibre were prepared and various properties were compared with a control mix specimen after 28 days. Compressive strength test was conducted for determining the changes in physical properties of the mortar due to the effect of salinity and urination. Study on interfacial bonding between matrix and reinforcement carried out by using SEM analysis. The test result suggested that fibre-reinforced plaster was able to achieve adequate strength if curing water contains salinity of 3.5% (35 g/L) and crop nutrient (NPK-46-0-0) of 40% w/v dissolved form in freshwater. This type of concrete could be used in non-structural components like warehouse flooring, industrial floor, water tank, benches or footpath near sea beaches, etc.
