Abstract

The present research works aims at the production of self compacting concretes with higher strength and durability by utilizing cement replacement and fibre reinforcement. Generally SCC has more powder content than the normal concrete to enhance their fluidity and hence to minimize the cement utilization, zeolite and silica fume has been used as cement replacement at 15% each by weight of cement. To provide flexibility, natural fibres (sisal and Prosopis juliflora) have been used at 1% by cement weight. Using expansive agents CaO and MgO with wide ranging proportions (0%, 2%, 4%, 6%), the fluidity is enhanced due to the dispersive effect produced by these agents. The utilization of super-plasticizers was also be reduced due to the expansive agents thereby the construction cost is reduced. The shrinkage resistance of the concrete was improved with high flexural strength with increasing expansive agent additions upto 1.5%. The developed self compacting concrete mixes containing expansive agents can also be commercialized for use in specific applications.
