Partial cement Replaceable Material
An experimental program is conducted to develop new kinds of pozzolana from
other agricultural wastes apart from rice husk and rice straw. The study investigated the use of coconut husk, corn cob and peanut shell ash as cement replacement materials. A series of tests were performed to determine the chemical composition of coconut husk ash, corn -cob ash and peanut shell ash which are referred to as CHA, CCA and PSA respectively.
The mechanical properties of paste and mortar containing different percentages of ash replacement were investigated. Experimental results revealed that coconut husk ash and corn cob ash cannot be utilized as pozzolona while peanut shell ash can be classified as Class ‘C’ pozzolona according to ASTM Standards. Corn cob ash mortars possessed higher compressive strength. Among the four types of mortars tested for chemical attack, PSA mortars showed higher resistance against acidic attack.

High Performance Concrete
The current trend of use of superlatives in concrete technology may strike as
somewhat disconcerting to many .We had high strength concrete, hyperplasticiser, and
superplasticisers, very reactive Pozzolana, and now high performance concrete. It is difficult to imagine any concrete being manufactured and used, which is not intended to perform to the extent; high performance concrete is not a new material of construction.
