DEVELOPMENT OF HIGH STRENGTH SELF CONSOLIDATING CONCRETE CONTAINING FLY ASH AND GGBS

Abstract

Self-consolidating/compacting concrete (SCC) is used in a wide range forpurpose of construction of high raised buildings, pavements and industrial applications which may be suitable to a highrange of temperatures to support fire resistance. The meaning of standard temperatures on the properties of self-compacting concrete is necessary. This presents the reports of laboratory experimental investigations carried out in order to study on the development of High performance and high Strength Self Consolidating Concrete containing/using GGBS, fly ash, and cement as a binder and its effect on the compressive strength of concrete at standard water-cement ratio in self-compacting concrete. It is found that the compressive strength of self-compacting concrete decreases with increasing in temperature. It is compared with normal-strength self-compacting concrete to possess a larger amount of compressive strength of concrete which is exposed to high strength temperature. In the experiment, flyash was varied by 5%, 15%, 25%, and 35%. GGBS was kept constant at 20% for all mixes. Cement was proportioned as 75%, 65%, 55%, and 45% respectively. The mechanical properties of the self compacting concrete are Compressive strength, Split Tensile Strength, and Flexural properties were examined by replacing VMA with conplast 430.
