Abstract

Fine Aggregate is one of the important ingredients of concrete. However dredging of Sand from river beds is hazardous to the environment. This has made the Government to restrictions on the use of river sand in construction. Such cases leads use of crushed sand as an alternative to river sand, due to angular shape and rough texture it gives better bond strength. Compaction of normal concrete is impossible at the place of dense reinforcement where needle vibrator can not reach, at that place Self Compacting Concrete is effective to reach at every corner of formwork, and get compact by its self weight. In design of structures, shear strength of concrete is very important for calculating the quantity of shear reinforcement. Shear strength of concrete depends upon Compressive strength. In this present work an attempt is made to study the shear strength of River Sand Self Compacting Concrete with varying the percentage of shear reinforcement by 0 %, 0.25 % and 0.50 % at shear plane of Push-off specimen. Load-deflections variations of SCC with River sand and SCC with Crushed sand are also studied. For compressive and shear test of 100 mm ×100mm cube and 150 mm ×150 mm × 450 mm push-off specimen were used. In this experimental study it is observed that the shear strength of CSSCC becomes more than RSSCC at same w/c ratio.
