The lightweight aggregate is an aggregate that weighs less than the usual rock aggregate and the quarry dust is a rock particle used in the concrete for the experimentation. The significant intention of the proposed technique is to frame a mathematical modeling with the aid of the optimization techniques. The mathematical modeling is done by minimizing the cost and time consumed in the case of ...
The limiting temperature is different for fly ash aggregate and quarry dust aggregate concrete. The limiting temperature of fly ash aggregate concrete is 300 °C and that of quarry dust aggregate concrete is 400 °C. This is due to the variation in the agglomeration process of fly ash and quarry dust in cold bonding process.

Further when fly ash is partially replaced with cement from 0 to 30% in mortar with 20% quarry dust (QF series), there is an overall increase in strength at 3 days, 7 days, and 28 days of age. The drop in compressive strength due to conversion reaction decreases with increase in fly ash content for a given water to powder ratio.
