When the dosage of fly ash increased to 30 g per 100 ml of mud sample, the curve tend to gentle. In the case of low dosage, that the effect of improving sludge dewatering performance for fine fly ash is more obvious than coarse fly ash, with the increase of dosage of fly ash, the ability of improving specific resistance for the coarse and fine
ing glass powder content as 25% of fly ash. The slump value obtained for normal fly ash based geopolymer concrete was 48mm while the slump value obtained for 25% glass powder replacement was 79mm which was 65% higher than normal fly ash based geopolymer concrete. The increase in workability with the increase in glass
Fly ash is a fine powder which is a by product from burning pulverized coal in electric generation power plants. The fly ash produced by coalfired power plants provide an excellent prime material used in blended cement, mosaic tiles, and hollow blocks among others.

In this investigation, cement, fine aggregate, coarse aggregate, ClassC fly ash and glass powder (90µ) has been used. Ordinary Portland cement of grade 53 was used in this investigation confirming to the standards of ACI544:IR96. The maximum size of the coarse aggregate was .
powder as a industrial waste and Fly ash as a pozzolana material. The established benefits substitution marble powder and fly ash by cement to make concrete such as economic, saving landfill, Reduce CO2 emission by the use of less cement. The amount of marble powder .
In addition, after processing and grinding the total cost of glass powder might be increased up to BDT/kg. Therefore, considering price of a 50kg cement bag as 450 BDT, replacing 10 and 20% cement by glass powder can reduce its price by 7% and 14% respectively. Fig. 7 gives cost and compressive strength comparison.
Hydrated fly ash is a material currently used to make aggregate for flexible base material. Hydrated fly ash is produced by allowing the powder fly ash from coal power plants to cure with moisture. The hydrated (cured) fly ash becomes a stiff material and is crushed to form an aggregate. When properly processed, the hydrated fly ash
