Influence on Mechanical and Thermal Expansion Properties of Short Roselle Fibers-Reinforced Cement Base Composite Materials

Abstract

This paper describes an experimental investigation on the mechanical, physical and thermal expansion properties of cement reinforced with Roselle fibres. The short discrete fibre length of (5-7mm) were used as reinforcement which were randomly oriented and uniformly distributed in the cement matrix and with various volume fraction of fibre cement ratio of (0-4%). The flexural strength, fracture energy, and thermal expansion of composites were found to increase as the fiber volume fraction was increased, while the elastic modulus was decreased, and also the results of the physical properties showed that a lightweight construction materials was obtained.
