“…In a rapid chloride permeability test (RCPT), because of the fineness and rate of reactivity of sugarcane bagasse ash (SCRHA) in concrete, agro-cement enhanced the resistance of chloride penetration in concrete at concentration up to 25% SCRHA [84]. It was also found that the reaction of SCRHA with free lime in Portland cement produced an additional C-S-H gel [85]. Apart from simply using biomass wastes from agriculture, mixing this with waste polypropylene carpet fibers has the advantage of being very lightweight, having superior resistance to sulfate and acid attacks, and possessing a hydrophobic nature from the carpet fibers, in addition to facilitating in disposal of textile and carpet industrial waste.…”

Concrete, as the world’s most implemented construction material, is increasingly being used because of the rapid development of industrialization and urbanization. Limited resources and progressive depravation of the environment are forcing scientific efforts to seek alternative and effective materials from large amounts of natural resources as additives in the partial replacement of cement. Cement is a main constituent of concrete. To solve and minimize environmental issues, research works attempting to employ the wide availability of agricultural wastes, such as sugar cane bagasse, rice husk, sugar cane straw, and palm oil fuel, among others, into cement, and to finally bring sustainable and environmentally friendly properties to concrete are being examined. Agro-waste materials are crushed into fine and coarse aggregates or are burnt into ash, and are then mixed with cement, which is known as agro-cement. The replacement of aggregates, either partially or fully, is also deemed as a sustainable material in construction. This paper mainly reviews the current research on agro-cement that has been researched and applied for the enhancement of the strength and durability of concrete. It further summarizes the relevant knowledge and techniques, while providing optimal parameters for applying agricultural wastes in concrete.

“…Concrete appears the premise of the structural business nowadays, yet it discharges CO2 at a rate of approximately 1 ton for each ton of concrete manufactured [1]. To decrease the measure of CO2 discharge from the cement business, the process of manufacturing must be enhanced to diminish its discharges of air contamination [2]. To meet the needs of sustainable development and environment preservation, new materials which are environment friendly were required to replace the conventional concrete manufactured from OPC and are termed as geopolymers.…”

“…Alkali activated binders are typically produced with an aluminosilicate precursor and an activator which is primarily consists of alkalis of Na or K and waterglass. Few investigations have inspected the impact of variables (silica fume [2], fly ash [4] and metakaolin [5]) that persuades the development of alkali activated slag (AAS) activated with common activators.…”

The study on the characteristics of geopolymer concrete (GPC) is of ultimate significance to instill assurance in builders and engineers. Abundant available literatures point towards the utilization of fly ash and ground granulated blast furnace slag (GGBFS) as source material in the production of GPC with little on other materials. India produces nearly 350 MMT of sugarcane for the production of sugar, which lies second only to Brazil in the annual production, the disposal of the bagasse creates an environmental issue needs to be effectively utilized. Hence, this work was intended to investigate the effect of utilizing sugarcane bagasse ash (SCBA) as a source material in the production of geopolymer mixes. The fresh (consistency, setting time, soundness and flow), hardened (density, compressive strength, expansion and pH) and microstructural properties (X-ray diffraction) of the tested mixes were asessed. The results infer that 20 % replacement level of GGBFS with SCBA produces superior compressive strength and all other results were within the permissible limits even at 40 % replacement level.

“…Some researchers have reported that the pozzolanic reactivity of bagasse may improve the compressive strength of concrete and enhance other mechanical and durabilityrelated properties (Rukzon and Chindaprasirt, 2012;Somna et al, 2012;Akkarapongtrakul et al, 2017). Since the main compound in bagasse ash is silica oxide, several searchers have reported its potential use in concrete.…”

Sugarcane bagasse is an agricultural waste that can be transformed by incineration into a cement replacement material for various cementing purposes. This study investigated the role of finely ground bagasse ash (GBA) in producing engineered cementitious composites (ECCs) with the addition of polyvinyl alcohol (PVA) fibers. The main focus of this study was to develop a green ECC with higher strength capabilities (compressive, tensile, and flexural) and greater tensile ductility. To develop this composite, GBA was added into ECC mixes at different proportions, i.e., 10, 20, and 30%. The proportions of PVA fibers and the water-to-binder ratio were kept constant. The results revealed that the ECC mix containing 10% GBA exhibited higher compressive strength compared to that of a control and the other ECC mixes. The tensile and flexural strengths of the ECCs exhibited patterns almost similar to that of compressive strength. Moreover, the deflection in the control mix was higher compared to that of the GBA-ECC mixes at an initial curing age. The ECC mix containing 10% GBA exhibited better ductile behavior among all the ECC mixes used in this study.
