Some studies on steam cured fly ash-lime bricks

Fly ashes, collected from different sources, were mixed with lime in various ratios and compacted in the form of bricks. The bricks were subjected to steam curing for different time periods to develop optimum strength in them through the reaction between fly ash and lime. Free lime content, compressive strength, bulk density and water absorption tendency of these bricks were measured as a function of compaction pressure. The kinetics of the water absorption and desorption tendency of the steam cured compacts was studied.
