Combining different types of fibers inside a concrete mixture was revealed to improve the strength properties of cementitious matrices by monitoring crack initiation and *** contribution of hybrid fibers needs to be thoroughly investigated,considering various parameters such as fibers type and *** present study aims to carry out some mechanical and microstructural characteristics of Waste Ceramic Optimal Concrete(WOC)reinforced by hybrid *** materials consist of three different fiber types:hook-ended steel fiber(HK),crimped steel fiber(CR)and polyvinyl alcohol(PVA)fibers and the effect of their addition on the waste ceramic composites’mechanical ***,a microstructural analysis was carried out to understand the waste ceramic matrix composition and its bonding to hybrid *** showed that the addition of hybrid fibers improved the strength characteristics of the ceramic waste *** instance,the existence of PVA-CR increased the tensile and flexural strength of the waste ceramic composite by 85.44%and 70.37%,respectively,with respect to the control sample(WOC).As well as hybrid fiber exhibits improved morphological properties as a result of increased pore filling with dense and compact structure,as well as increased C-H crystals and denser structure in pastes as a result of the incorporation of hybrid fibers into the concrete *** present experimental research shows the choice of using steel fiber with PVA as a reinforcement *** idea of adding hybrid fiber is to prepare the economic,environmental,and technological ***,it offers a possibility for improving concrete’s durability,which is ***,it was concluded that steel fiber is more durable,and stiffer and provides adequate first crack strength and ultimate *** contrast,the PVA fiber is relatively flexible and improves the post-crack zone’s toughness and strain capacity.
