Synopsis "Fiber Reinforced Self Compacting Concrete (in English)"
Self-compacting concrete (SCC) is a new concrete technology developed during last two decades and it has become very popular in the construction industry. Filling ability, Passing ability and Resistance against segregation & bleeding, are the main properties of Self-compacting concrete. The main problem in designing of SCC is the selection of appropriate ingredients. All super plasticizers and viscosity modifying admixtures (VMA) are not compatible with any kind of cement. An experimental investigation has been undertaken to produce Self-compacting mortar and Self-compacting concrete to understand cement-plasticizers or admixture compatibility problem. Further,the harden properties of SCC was improved by addition of polypropylene fibers. The common problem associated with the use of fiber in concrete is the reduction in workability. However, the flow properties for SCC can be achieved in presence of fiber using new generation plasticizers and additives.The present research also describes the manufacturing process and rheological aspects of newly developed fiber reinforced self compacting mortar
