Potential Use of Fly Ash for Developing Angular-shaped Aggregate

The prices of aggregate are increasing in India due to the massive demand for natural infrastructure development. An attempt has been made check feasibility past developed technique developing angular-shaped light-weight fly ash coarse from three different types ashes. In this study, effects binder content, water content and hot bath curing temperature on compressive strength blocks, as well impact value prepared ash-binder mixes were investigated. A relationship between also suggested predict based block. For making aggregate, it was found that with CaO 0.71%-3.85% requires higher than required 10.45%. resulting lightweight aggregates ashes have a compacted structure angular shape good interlocking. results mechanical properties test showed meets criteria Indian code specifications structural concrete aggregate.
