Surkhi in construction is an artificial pozzolana which is produced from clay by burning and grinding it. Surkhi powder is quite used in the construction industry. It is artificial pozzolana obtained after burning the or burnt clay balls at a specified temperature. Surkhi was used in other countries too, but with other names: India
Calcium fly ash. Generally speaking, fly ash is made up of agglomerates of fine particles ranging from gray to black. The main constituents being silica and alumina, the average density is close to g / cm3. The specific surface area varies between 2000 to 4000 cm21g, and the density of dry fly ash in bulk varies from 550 to 900 kg / m
For the experimental study, the asreceived pulp mill fly ash (PFA) and a fly ashbased geopolymer synthesized by alkalisilicate activation method, were incorporated as cement substitutes in the RE mixtures. Initially, the local soil was collected and characterized by important index and engineering properties.
The global flyash market was valued at US Bn. in 2020, and it is expected to reach US Bn. by 2027 with a CAGR of % during the forecast period. Fly ash, also known as flue ash or coal ash, is a coal combustion product made up of particulates (fine particles of burned fuel) and flue gases that are discharged from coalfired boilers.

The use of fly ash a recovered resource reduces the depletion of natural resources It also reduces the energy intensive manufacturing of portland cement This reduction in energy leads to less emissions of greenhouse gases The use of a ton of fly ash to replace a ton of cement saves enough electricity to power an average american home for 24 days.
Fly ash (FA) was washed with distilled water followed by drying at 100C for 24h. Dried FA was mechanically activated using high energy planetary ball mill (Retsch PM100, Germany) in an agate grinding jar using agate balls of 5 mm ball sizes for 5, 10 and 15 hours with 250 rpm rotation speed. The ball mill was loaded with ball to powder
29/08/2019The specific surface of fly ash and GGBS are and m 2 /g respectively and both these materials are nonplastic in nature. Owing to greater specific surface area of fly ash, a mix containing higher fraction of fly ash, requires more amount of alkaline solution to lubricate the particle surface and thus it exhibits greater consistency
