Study on mechanical and thermal properties of sisal fiber/cloisite 30B nanoclay reinforced cement nano concrete

Natural fibers and nanomaterials are currently receiving more attention in the construction sector for two reasons. One reason is to use natural fibers instead of synthetic ones in fiber-reinforced concrete to create environmentally friendly products. In this study, sisal fiber ( SF) and Cloisite 30B nanoclay particles were used to manufacture cement nano concrete. The cement nano concrete was reinforced with 3 wt% 10 mm sisal fiber and varying levels of Cloisite 30B nanoclay (0%, 0.5%, 1%, 1.5%, and 2%). Comprehensive research was conducted to evaluate the physical, mechanical, thermal, and water absorption properties of the concrete. The results indicate that the incorporation of nanoclay enhances these qualities. The results of the experiments indicated above demonstrate that the 3 wt% SF and 1.5% nanoclay concrete has superior mechanical qualities to other nanoclay concrete in terms of compressive strength (7.12 MPa) and flexural strength (9.6 MPa). Additionally, testing was performed on the concrete's morphology, physical properties, and water absorption.
