Abstract
This review paper presents a comprehensive comparative analysis of various studies conducted on the shear strength of Self-compacting Concrete (SCC) and Normally Vibrated Concrete (NVC) in order to determine the sustainability and affordability of SCC as a construction material. Compaction is the main factor in concrete production. NVC needs compaction and vibration to remove the entrapped air which is both expensive and time-consuming. But SCC has flow ability and passing ability. Although SCC takes a greater amount of paste content, thereby raising the cost of building material, yet the use of such waste material as fly ash, silica, etc. comes in handy as paste content. Thus, the advantages offered by SCC in terms of increased strength as well as cost reduction makes it a highly desirable construction material. The review has selected the works of some eminent scholars on concrete and has analyzed them through individual as well as comparative perspective. A close analysis has helped filter out relevant works for the current study. This process of selection has proved helpful to include most standard works available in the review. Major findings have been enlisted at the end and ways to improve concrete behaviour have been suggested. Doi: 10.28991/cej-2021-03091661 Full Text: PDF
Highlights
It is a well-known fact that shear capacity is one of determining factors in robust building construction
The findings suggested that Self-Compacting Concrete (SCC) is workable when its water binder ratio varies between 0.35 to 0.42
SCC is more cost-effective and environment-friendly as it uses fly ash, silica, etc. as ingredients. It has another peculiar advantage over normal concrete in that it does not need vibrator to settle the paste content, thereby saving time in the preparation of concrete
Summary
It is a well-known fact that shear capacity is one of determining factors in robust building construction. This capacity is generated by beams having longitudinal structure aided by stirrups which produces a high compression force and tension reinforcement [1,2,3]. With the advancement in civil engineering technology, extensive research has been carried out on shear capacity of concrete structures, proposing various models/designs [4,5]. Self-Compacting Concrete (SCC) has emerged as a promising building material considering its low cost and high performance. It is the latest generation concrete having both low and high grades. The present paper attempts to document some of the prominent models and designs in order to select the best out of them
