The development of new type of high performance concrete, such as self- compacting concrete (SCC) or lightweight concrete (LWC) responds to some requirements of the construction industry. Due to the reduced weight LWCs have other advantages compared to normal-weight concrete, such as good fire resistance and improved heat insulation. Sintered fly ash aggregate is the best for the use in structural applications. In addition to the light weight aggregate fibres which are best known for resisting cracks, fatigue , bending , durability etc are also included to get more effective outputs from the members.
