heavy metal contamination in the environment could cause harmful effects both to human health and aquatic life. numerous remediation methods had been developed to encounter with the contamination problem prior to degrade, decrease and to purify the contaminated water at minimal concentration as low as possible. therefore, in current study, commercialized chicken eggshells and hybrid akar putra ...

Self-compacting concrete is an innovative technology with higher flowability properties by adding the mineral admixtures such as superplasticizers and not necessary to vibrate concrete. The banana fibers were used in this investigation because fiber environmentally friendly material good compared synthetic fiber. experimental test consisted of two phases research, i.e., preliminary which had ai...

This research aimed to study the impact response of topology optimized hammerhead pier beam (HPB) based on density approach. The HPB is prepared with concept preplaced aggregate fibrous concrete (PAFC) comprising two primary approaches; first, coarse and fiber are prepacked into designed formwork. Second, gaps between filled cement grout. In this work, an attempt has been made PAFC. Five HPBs w...

The use of synthetic fibers as reinforcement in fiber-reinforced cementitious composites (FRCC) demonstrates a combination better ductile response vis-à-vis metallic ones, enhanced durability high pH environment, and resistance to corrosion well self-healing capabilities. This study explores the effect macro- micro-scale polypropylene (PP) on post-crack energy, ductility, potential FRCC. Labora...

The unsustainable use of resources and the rising demand for traditional concrete have disrupted ecological equilibrium, necessitating adoption a more appropriate long-lasting alternative. One such substitute cement in production is geopolymer concrete, although this material prone to cracking fracturing due its low tensile strength, leading costly repairs or even structural collapse. Fiber-rei...

This paper present the experimental result of flexural behavior Hybrid Fiber Reinforced Polymer (HFRP) concrete beams reinforced with Glass (GFRP) rebars and steel bars. experiment is conducted aim replacing reinforcement GFRP to reduce risk corrosion in structures. The data presented this study obtained by conducting test on four HFRP various PVA fibre dosage 0%, 0.25% 0.5% one Pure FRP beam. ...
