Paper Title
Influence Of Mineral And Chemical Admixtures In Portland Pozzolona Cement Mortar Using River And Standard Sand
  C V S Nagendra,  K N Rukmini Florence

To fulfil the demands of cement and reduce the production of cement. In the present research, the supplementary cementious materials (SCMs) or mineral admixtures like fly ash, silica fume, metakaolin and ground granulated blast furnace slag(GGBS) are used in cement composite by partial replacement of cement about 20% and studied the properties of cement composite using river and standard sand. By adding this type of SCMs in cement the performance with regard to water requirement for consistency, setting time and preparation of cement mortar with and without addition of superplasticizer (SP) may demand less or more water as compared to cement alone. The present study gives the requirement of water at different stages of consistency and also the mechanical and durability properties of cement mortar are studied by preparation of mortarcubes.and in the present study PPC is used to determine the change in properties by addition ofadmixtures. In general, most expensive most expensive ingredient among construction materials is undoubtedly cement both economically and environmentally. Normally cement contains many ingredients like oxides of calcium(ca0),silica(sio2),aluminium(alo3),iron(fe203),magnesium(MgO) and alkali’s like Na2O and K20 and the main products of hydration of cement are calcium silicate hydrates(C-S-H).calcium hydroxides(CH),and calcium aluminate hydrates(C-A-H).The changes in addition of admixtures to cement affects the rate, quantity and quality of hydration products which eventually results in changes in the demand of water requirement, strength and durability property of the cement paste.
