EXPERIMENTAL STUDY ON HIGH STRENGTH SELF COMPACTING CONCRETE INCORPARETED WITH CARBON FIBRE

The Self - Compacting Concrete[ 1] is a concrete which flows and settles due to its own weight without segregation and bleeding .Self - Compacting Concrete is cast so that no additional inner or outer vibration is necessary for the compaction. It flows like “honey” and has a very smooth su rface level[2] after placing with regard to its composition, self - compacting concrete consist of the same components as conventionally vibrated concrete, which are cement, aggregate and water, with the addition of chemical and mineral admixtures in differe nt propositions. . In this study, the trial mix is carried out the cement content is partially replaced with i.e., micro silica that improve the flow ability and strengthening characteristics of the concrete. From these trials, which trial shows the maxim um Strength that is adopted as optimum mix based on both workability and strength criteria. That trial is chosen and fibers are added in it. Carbon fiber is added with 0.2% increment into the maximum strength attaining concrete mix i.e 0.2%, 0.4%, 0.6%, 0. 8%. The chemical admixtures used are High - Range Water Reducers (super plasticizers) and Viscosity Modifying Agents, which change the rheological properties of concrete. Cubes beam and cylinders is casted for determine the compressive strength, split tensil e strength and flexural strength.
