Durability of high strength flowing concrete with hybrid fibres

This study was conducted to investigate the mechanical properties and the durability by using of different percentages of steel fibre with high strength flowing concrete (HSFC) and also the use of the hybridization of steel fibres, palm fibres and synthetic fibre (Barchip). Compressive strength, splitting tensile strength, flexural strength, static modulus of elasticity and permeability tests were determined after normal water curing and seawater exposure. The results show that the uses of 0.25–0.5% of the palm and Barchip fibres with 1.5–1.75% of steel fibre in HSFC mixes boost the best performance of compressive strength, splitting tensile strength, flexural strength among others. Besides, these percentages of fibres inclusions in HSFC were found to be effective when the HSFC exposed to seawater.

High strength characteristics of cement mortar reinforced with hybrid fibres

An experimental study was conducted on high strength mortar reinforced with steel fibres and hybrid fibres consisting of steel fibre, palm fibre and synthetic fibre (Barchip). The inclusion of fibres was maintained at a volumetric fraction of 2%. The compressive strength, splitting tensile strength, static modulus of elasticity, shrinkage, flexural strength, and flexural toughness were determined to study the effect of the hybrid fibres on the properties of high strength cement mortar (HSCM). The results showed that hybridization of fibres in the quantities 1.5% steel fibres + 0.25% palm fibres + 0.25% Barchip fibres, improved the compressive strength and flexural toughness significantly, and also enhanced the splitting tensile strength and flexural strength of the mortar by about 44% and 140%, respectively.
