Using the fly residue as the substance of choice for bonding in concrete, it reduces the use of normal Portland cement in usual concrete that results in the development of Geopolymer concrete in addition to the decrease of CO2 levels that reduces Global Warming. Methods / Statistical analysis: This paper presents the test test carried out on the execution of geopolymer concrete based on fly residues reinforced with fibers of coconut fiber subject to severe ecological conditions. The blends were considered for 10M molarity. The basic arrangement used for the current review is the mixture of sodium silicate and sodium hydroxide in the ratio of 1: 2.5. Coconut fiber with variable percentages of 0, 0.75, 1.5, 2.25 and 3 are used as fiber reinforcement. Test specimens of 150mmx150mmx150mm cubes, 150mmx300mm cylinders, 1000mmx150mmx150mm beams are melted and cured in encompassing temperature conditions. Findings: Solid geopolymer examples are tested for compressive, flexural, and fracturability tests at 7 days, 14 days, and 28 days. Test grades demonstrate that the mixture of fly ash and coconut fiber can be used to improve the geopolymer concrete. Applications: It has superior distinctive character, such as high resistance, very low drying contraction, low creep, durable nature, eco-friendly, fire resistance, better resistance to compression, etc., to be used as an OPC alternative.
Fly ash of category 'C' was used as raw material for the partial replacement of clay to make fly ash bricks. Not only the affectivity of fly ash with high replacement was studied, but also the mechanical properties of the bricks with different combinations. It is observed that the compressive strength of the single fly ash and the treated fly ash (FAB, FALB) increases linearly and is found to be maximal with a combination of coarse sand of 5% coarse sand and 15% sand at 10% cement. This increase in compressive strength continues with the addition of 0.2% of geofibre in FAB and FALB. The addition of 10% of stone powder in FALSDB with and without geo-fiber shows the achievement in strength that is, maximum in a 10% replenishment of sand. The combination of fiber-reinforced fly ash lime stone (10FRFALSDB3 ') was found to have the highest compressive strength with a combination of 10% stone and sand powder with 10% cement. It is observed that when the amount of treated fly ash changes with respect to stone powder and sand replacement, the compressive strength increases and it has been found to be maximum 25% stone-sand mixture with 50% fly ash treated. With this change the increase in compressive strength reached maximum which is almost close to first class Indian brick.
