Abstract: The construction industry in India is growing at a rapid pace to meet the housing demand and
other infrastructure requirements. The construction industry needs sustainable structures and
self-compacting concrete (SCC) is actively considered for many projects due to the several
benefits it offers including faster project cycle times. Moreover, structures involving thin
precast sections and highly congested reinforcement require SCC for ease of placing and
finishing. Production of SCC with locally available resources such as crushed sand as fine
aggregate, is a real challenge faced by concrete experts in India as the materials have variable
property across different regions of the country. The concept of construction using shear wall
technology is prevalent in the housing sector in India, where the thickness of walls varies
between 100 mm and 200 mm, and SCC is often the favoured choice. In this paper two
project case studies have been presented where SCC is produced with locally available
materials at Chennai and Mumbai. The Chennai SCC is of compressive strength grade M30
whereas the Mumbai SCC is M70. It is interesting to note that despite the fact that the two
mixes do not strictly conform to the EFNARC requirements, they have been used
successfully and in terms of pumpability, fillability and finish characteristics they are second
to none. This is also supported by typical applications in India for mass concrete pours and
aesthetic requirements of fair finish face concrete.
