Micro-concrete (MC) can be defined as a high-performance cement-based material produced using microaggregates and cement in the required proportions. Owing to its high performance, it has potential used structural repairs of existing building elements. Within scope this study, an evaluation was conducted by creating usage scenario under which glass, is waste product, reduced applied way that pr...

This paper aims to study the permeability of High-Performance Concrete containing natural pozzolan and reinforced with fibers in high concentration sodium chloride solution. Optimized finely ground was employed as 6% partial substitution cement. Polypropylene 6 mm 12 lengths were introduced individually for a volume fraction 0.1% 0.15% respectively. Then, combination total fiber content 0.25%. ...

Geopolymers can replace cement and help reduce the environmental impact of concrete construction, but research is needed to ensure their mechanical properties, durability practicability. The aim this investigation examine influence ground granulated blast furnace slag (slag) content on performance, at fresh hardened states, fly ash (FA) based self-compacted geopolymer (SCGC). For purpose, four ...

Abstract The efficiency of bio self-healing pre-cracked mortar specimens incubated in sand was investigated. investigation examined the effect soil pH representing industrially recognised classes exposure, ranging from no risk chemical attack (neutral ? 7) to very high (pH 4.5). Simultaneously, subjected fully and partially saturated cycles for 120 days resemble groundwater-level fluctuation. B...

Growing concrete consumption has gradually depleted conventional resources. This research incorporates silicomanganese (SiMn) slag, marine sand and seawater as alternative concreting materials. The use of SiMn slag to replace limestone coarse aggregate enhances sustainability, though reducing strength durability concrete. aims enhance the by incorporating silica fume (SF) fly ash (FA). interact...

Abstract Soil water repellency (SWR) reduces the rates of wetting in dry soils and is known to interfere with movement into as well within soils. The objective this study was investigate hydrophysical characteristics three water-repellent tropical exotic plantation forest wet seasons. sites were Eucalyptus grandis (EG), Pinus caribaea (PC), Casuarina equisetifolia (CE) located up-country interm...

The growth of the construction industry has expanded demand for ceramic building products such as tiles, which constitute essential materials. Nonetheless, a huge quantity waste powder is produced during polishing tiles. disposal key environmental concern that needs to be properly addressed. purpose this research evaluate potential recycling geopolymer binder. main objective consists exploring ...

Concrete's ability to auto-repair the cracks reduces need for maintenance and repair. Autogenous self-healing is an intrinsic property of concrete highly dependent on binder composition. The urgent necessity decrease CO2 emissions by replacing cement with “greener” materials provides challenges opportunities cementitious materials. This research aims verify behavior environmentally friendly mul...

The importance of the incorporation nanomaterials in concrete has emerged as a promising research interest due to outstanding functionalized properties materials at that size level. This study aims investigate engineering and durability incorporated with hybrid nanomaterials. In this study, influence carbon nanotube (CNT) on microstructure, mechanical, corrosion characteristics nano-clay-based ...
