Experimental Study of Elevated Temperature Effects on Properties of Nano Clay and Glass Fiber Concrete

Abstract

Concrete is mostly use construction material. Concrete is composite material composed of fine and coarse aggregate bonded together with a cement paste that cure over time. Generally concrete is strong in compression and weak in tension. Concrete is brittle material and will crack when we increasing tensile force. Nano clay are nano-size particles of layered mineral silicates. Adding a nano clay is a could fill the original hydration products pores and colloid capillaries increase the cement paste density of concrete. Alkali-resistant glass fiber has a high degree of corrosion resistance in the environment of cement and other alkaline medium. Glass fiber gives high tensile strength. Objective of research is increase mechanical strength of concrete with use of nano clay (NC) and glass fiber (GF). In present study, Concrete grade use is M30.In study 2% of NC is fix replacement of cement and variation of GF is use 0.5%,1%,1.5% as admixture. Temperature effect give 80℃,180℃,300℃for 3 hours. After adding NC and GF check the difference test result like a slump, Compressive, split tensile and flexural strength test. The specimens will be tested on 3,7, and 28 days.
