The concrete’s compressive strength, thermal conductivity, and modulus elasticity were assessed. X-ray diffraction (XRD) analysis was understand differences in mineralogical composition rapid chloride penetration test (RCPT) investigate changes permeability ions imposed by GO addition. showed that 0.25 wt.% increases strength GBFS-FA concrete 30.5% 37.5%,...

In recent decades, several studies have considered the use of plastic waste as a partial substitute for aggregate in green concrete. Such concrete has been limited to non-structural applications due its low strength. This raises whether such can be enhanced some structural applications. paper reports an attempt develop structural-grade containing with high proportions substitution and confined carbon fiber reinforced polymer (CFRP) fabrics. Experimental research was conducted involving...

In current state of the World, pollution is increasing very fast. One its major reason production huge quantity cement which causes outflow CO2 into environment and land dumping construction demolition waste leads to pollution. order address this issue, it important decrease utilization by substituting with product such as slag using recycled aggregates a replacement natural aggregates. This research aimed utilize evaluate performance sustainable high-performance concrete reinforced steel...

Abstract Today, it’s getting harder to find natural resources for concrete production. Utilization of the waste materials not just helps in them used concrete, cement, and other construction materials, but also has various secondary advantages, example, saving energy, decrease landfill cost, protecting climate from pollution. Considering this development modern structural design, utilizing instead aggregate is a good option make that sustainable eco-friendly. The present research aims impact...

The production of rice is significant worldwide; the husk produced generally used as a combustible material for preparation paddies, delivering energy through direct combustion well by gasifying. Annually, 7.4 million tons Rice Husk Ash (RHA) and poses an incredible danger to environment, harming land encompassing zone where it unloaded. In transformation ash, ignition cycle eliminates natural products, leaving silica-rich remains. These remains have proven potential be utilized in concrete...

Self-compacting concrete (SCC) is a special type of that highly flowable, nonsegregating and spread into place by its own weight, completely filling the formwork even in presence dense reinforcement then encapsulating rebar without need for any additional compaction. This research was carried out to evaluate effects bentonite clay wheat straw ash as partial substitution cement SSC. Bentonite were added proportion 0%, 5.0%, 10%, 15%, 20% weight cement. Fresh characteristics evaluated based on...

In the current study, utilization of glass and nylon fibers in various percentages are added to enhance mechanical performance peach shell lightweight concrete. Glass were at 2%, 4%, 6%, 8% by cement weight. The results showed that, as we fibers, density concrete was reduced 6.6%, compressive, split tensile flexural strength enhanced 10.20%, 60.1%, 63.49%. highest that obtained tensile, 56 days 29.4 MPa, 5.2 6.3 respectively, with 6% fiber Mechanical test post-failure toughness modulus...

Presently, the rate for development of ultra-high-performance concrete (UHPC) is increasing due to requirement long-span bridges, challenging architectural plans, and high-rise buildings. UHPC still weak in tension consumes a lot cement, making it non-eco-friendly. This research aimed at modifying cement's matrix by incorporating two sustainable solid waste mineral admixtures, eggshell powder (ESP) nano-silica (NS), enhance bonding between fibers binder's improve strength characteristics...

Because of the recent progress in materials properties, specifically high-strength concrete, further research is needed to evaluate its suitability, understanding, and performance modern-day world. This aims enhance ultra-high-strength geopolymer concrete (UHS-GPC) by adding nano-silica (NS) polypropylene fibers (PPFs). Three 1%, 2%, 3% different amounts PPFs three NS 5%, 10%, 15% were utilized samples. Various parameters UHS-GPC evaluated, such as fresh property, compressive strength,...

This study aims to assess the mechanical performance of functionally graded concrete (FGC) in comparison conventional plain cement (PCC) and fibre-reinforced (FRC). For this purpose, five mixes were prepared, defined eleven patterns, including PCC as a control mix, two FRC mixes, eight combinations for FGC mixes. The hooked-end steel fibres recycled thin polyethylene terephthalate (PET) strips from used bottles utilized 0.75 % volume mix natural aggregates replaced by 15 weight with plastic...

Stockpiling and landfilling of waste glass (WG) is becoming a severe environmental issue around the World as hundreds tons WG are dumped on land. The present research assesses behavior in concrete mixture partial replacement sand to attain optimal percentage glass. Due production ordinary Portland cement (OPC), natural reserves limestone depleting fast, OPC also leads high proportion carbon dioxide (CO2), so it essential utilize industrial by-products such fly ash (FA) replace partially. In...

Developing ultra-high fiber-reinforced concrete (UHPFRC) demands an immense quantity of ordinary Portland cement (OPC). Using a high percentage in UHPFRC leads to uneconomic and significant release CO2 into the atmosphere. Therefore, it is critical address this issue by substituting part with sustainable material. The current research has tried tackle assessing impact adding wheat straw ash (WSA) silica fume (SF) as partial substitute on properties static dynamic compressive strength test,...

Reprocessing solid waste materials is a low-cost method of preserving the environment, conserving natural resources, and reducing raw material consumption. Developing ultra-high-performance concrete requires an immense quantity materials. The current study seeks to tackle this issue by evaluating effect various discarded materials, glass (GW), marble (MW), rubber powder (WRP) as partial replacement fine aggregates on engineering properties sustainable fiber-reinforced geopolymer (UHPGPC)....
