In the last decades, environmental sector has occupied an essential place in world. The main objective of this concern is to preserve environment and reduce use non-renewable raw materials as much possible. Thus, construction can contribute conservation by bio-based materials. Bio-building are composed, at least part, components made from biomass derived plants or animals. Today, these used a variety produces for purposes, including insulation, mortar concrete, panels, plastic composites, chemistry. first step study, Physico-chemical (bulk density, absolute water absorption, relative humidity) thermal (thermal conductivity resistivity) properties wood ash, vegetable aggregates (sunflower plant bark pith) have been studied compared with results literature review. Afterward, different mixes were prepared based on ashes adding certain percentage cement binding material (0%, 10%, 20%) improve their mechanical behavior. Then, concrete ash (pith sunflower bark) was order optimize mixture that best performance. growth compressive flexural strength evaluated 7, 14, 28, 90 days. Because excellent ability maintain cohesion, obtained demonstrated possibility producing less cement. terms performance, increasing fiber content while decreasing volume density mortars.

The safe disposal of an enormous amount waste glass (WG) in several countries has become a severe environmental issue. In contrast, concrete production consumes large natural resources and contributes to greenhouse gas emissions. It is widely known that many kinds may be utilized rather than raw materials the field construction materials. However, for wide use building construction, it necessary ensure characteristics resulting are appropriate. Recycled one most attractive can used create sustainable compounds. Therefore, researchers focus on cement mortar by utilizing as aggregate or pozzolanic material. this article, literature discussing recycled partial complete replacement aggregates been reviewed focusing effect fresh mechanical properties concrete.

In this study, ground glass powder and crushed waste were used to replace coarse fine aggregates. Within the scope of aggregate (FA) (CA) changed separately with proportions 10%, 20%, 40%, 50%. According mechanical test, including compression, splitting tensile, flexural tests, creates a better pozzolanic effect increases strength, while particles tend decrease strength when they are swapped As observed in tensile noteworthy progress concrete was achieved by 14%, as fractional replacement for aggregate. samples where CA, tended decrease. It noticed that adding at 50% FA swapped, increase 3.2%, 6.3%, 11.1%, 4.8%, respectively, amount reference one (6.3 MPa). Scanning electron microscope (SEM) analysis consequences also confirm obtained from experimental study. While it is seen provides bonding cement its has positive on consequences, voids formed large pieces affects negatively. Furthermore, simple equations using existing data literature current study developed predict properties recycled practical applications. Based findings our 20% CA recommended.

Geopolymer (GP) concrete is a novel construction material that can be used in place of traditional Portland cement (PC) to reduce greenhouse gas emissions and effectively manage industrial waste. Fly ash (FA) has long been utilized as key constituent GPs, GP technology provides an environmentally benign alternative FA utilization. As result, thorough examination manufactured using precursor (FA-GP concrete) employed replacement for conventional become crucial. According the findings current investigations, FA-GP equal or superior mechanical physical characteristics compared PC concrete. This article reviews clean production, mix design, compressive strength (CS), microstructure (Ms) analyses collect publish most recent information data on In addition, this paper shall attempt develop comprehensive database based previous research study expounds impact substantial aspects such physio-chemical precursors, mixes, curing, additives, chemical activation CS The purpose work give viewers greater knowledge consequences uses making effective
