Mechanical properties of hybrid fiber reinforced coral concrete
Case Studies in Construction Materials, 2022 This paper investigated the effect of microfibers (carbon fibers and basalt fibers) and macrofibers (plastic steel fibers) on the mechanical properties of coral concrete. A total of 192 specimens were designed with carbon fibers (CFs), basalt fibers (BFs), and plastic steel fibers (PSFs) as variables.

An Experimental Study on fiber Reinforced Hybrid Concrete
International Journal of Innovative Research in Advanced Engineering, 2023 In this project modified hybrid concrete- a novel construction material is manufactured with fibers (steel fibers, polypropylene fibers) and silica fume by drilling through the cement and mortar in order to develop a high strength concrete. The main purpose is to develop a concrete with improved physical and mechanical properties.
