Abstract: Bulk utilization of coal ash as repository in light weight cementitious matrix composites using both peat ash as a binder and Manufactured Coal Ash Aggregates (MCAA) is an effective means of achieving carbon neutrality . MCAA are lighter in weight than conventional granite aggregates and can be used for production of structural grade concretes. Coalash is pozzolanic and capable of utilizing both heat and calcium hydroxide generated during hydration process of portland cement. Hence it has been used as partial cement replacement materials (CRM) as per the codes.
