(PDF) Fly ash as a sand replacement material in

Fly ash [24] can even be used as sand replacement material in cement concretes. This type of fly ash concrete has a lower density and manufacturing cost, a reduced coarse aggregate content, a1. Introduction. Fly ash is an industrial waste generated in power-plant boilers, carried out by gas stream and recovered in filters. Estimated global annual production of coal combustion byproducts, of which 80% represents fly ash and the remaining 20% is bottom ash, amounts to 500 million tons [1].The management of this Artificial fly ash based aggregates properties influence on

Fly ash-based geopolymer: clean production, properties

Fly ash is the fine solid particulate residue driven out of the boiler with the flue gases in coal-fired power plants. Now it can be used for making geopolymer which acts as a cement-like product. The geopolymer technology provides an alternative good solution to the utilization of fly ash with little negative impact on environment. This review In the present work, artificial aggregates were produced using an alkali-activated cold-bonding pelletization process with a high-volume of red mud as the precursor, fly ash as the additive, and a mixture of sodium silicate and sodium hydroxide as the activator. To obtain the optimum proportion for the aggregates, five mixture ratios were Alkali-activated artificial aggregates fabricated by red mud and fly

An investigation on the properties of ResearchGate

In this paper effect of addition of fly ash, artificial sand & steel fiber on the properties of SIFCON is reported. Waste steel fibers were used in SIFCON. In this study aspect ratios of steelUnconfined compressive strength (UCC) of untreated soil is 0.1688 N/mm2 and the treated soil with fly ash attains to a value of 0.333 N/mm 2 (10% fly ash) i.e., increases by 49.30% from the initial value and further down drift is observed in both CBR and UCC values. The study infers that, the use of fly ash up to 10% is recommended to Stabilization of expansive subgrade soil by using fly ash

Alkali-activated artificial aggregates fabricated by red mud and fly

The aggregates were synthesized with red mud (RM), fly ash (FA), and a sodium silicate solution. The RM was supplied by the Zhongzhou branch of the Aluminium Corporation of China Limited (Henan, China) in the form of a slurry with an average water content of 37.8 wt%.White mud is residue discharged during the acid method in the aluminum extraction process from coal fly ash, and this material is harmful to the environment. The implementation of an environmentally friendly and valuable way to use white mud is a key factor restricting the commercial application of the acid method in the fly ash alumina Minerals Free Full-Text Green Conversion of Coal Fly Ash

Applied technique of the cemented fill with fly ash and fine-sands

Specimens with different cement/fly/ash tailings (sands) ratios were tested to obtain the strength values of the fill mass based on the analyses of both the chemical composition and physical and mechanical properties of fly ash. The compressive strength of specimens with a ratio of 1:2:8 (cement to fly ash to tailings) can reach 2 MPa after 90The EU-funded SMARTSAND project developed Lypors™, an advanced engineered, artificial sand material manufactured from fly ash for use in the construction industry. “It is a superior and cost-effective alternative to natural sand, crushed stones and lightweight fine aggregates, for use in the manufacture of advanced building materialArtificial sand provides green solutions for the construction
