Abstract: Growth in the construction industry is growing daily
and the demolition of the old structure creates massive quantities
of rubbles and from that 30-40% were coarse aggregate. Utilizing
of coarse aggregates through recycling helps to give economic
and sustainable development. The aim of this study is to achieve
high compressive strength with minimum wear effect of new
concrete made of recycled concrete aggregate. To achieve aim in
this study has been considered high strength of concrete mix
i.e.M40, M50 and M60 for compressive strength and for abrasion
test, considered mix of M50 and M60. A replacement percentage
for the compressive strength test was 0%(normal), 20%, 40%,
60%, and 80% while for abrasion test considering 0%, 20%, 40%
and 60% replacement ratio. This research helps to use recycled
concrete aggregate in construction sector.
Index Terms: abrasion test, compressive strength test of RCA,
recycled concrete aggregate, waste of concrete and recycling.
I. INTRODUCTION
The global demand for aggregate building per year is
approximately. 26.8billion tonnes. This shows that in the
construction industry, the aggregate has an important role.
Growth in urbanization and population forecast is increasing,
requiring a large amount of development of infrastructure.
According to the Central Pollution Control Board (CPCB)
Delhi report, a total of 48 million tons of solid waste is
generated in India, of which 14.5 million tons of waste is
generated from the construction and demolition sector, only
3% of waste is transferred to the embankment. Out of the total
construction demolition waste, there are 40 percent of
concrete, 30% of ceramics, 5% of plastics, 10% of wood, 5%
of metal, and 10% of other mixtures. 70-75% aggregates are
essential to the creation of concrete. Of this 60-67% is
aggregate, of course, and 33-40% is fine aggregate.
According to the Freedonia Group's latest investigation,
world demand for construction aggregates will increase to
51.7 billion metric tons in 2019 by 5.2 percent annually. From
the environmental point of view, there are emissions of
0.0046 million tons of carbon for the manufacture of natural
aggregates of 1 ton while only 0.0024 million tons of carbon
is created for 1 ton recycled aggregate.

Considering the global use of 10 billion tons of aggregate per
year for concrete production, the carbon footprint can be
intended for both the natural aggregate and the recycled
aggregate. Considering the current environmental impact, one
of the good options for the construction industry is recycled
aggregate for economic and sustainable development. Using
recycled aggregate by replacing parent concrete opens up a
new path for civil industry.
II. LITERATURE REVIEW
In 1977, Frondistou-Yannas (2) analyzed and compared the
mechanical properties of conventional concrete and concrete
containing pieces of concrete from demolition waste in the
place of natural coarse aggregate. The recycled aggregate
concrete has a compressive strength of at least 76% and
modulus of elasticity from 60% to 100% of the control mix.
Akbarnezhad, K. C. G. Ong, C. T. Tam3, and M. H. Zhang
(3) found that the properties of RCA and compressive
strength of RAC were observed to be mainly affected by the
mortar content of RCA. The mortar content of RCA was
depending on the size of the natural aggregates in the parent
concrete.
III. OBJECTIVE
The objective of this research to achieve high strength and
more durability against environmental effects. The concrete
mix was produced with 0%, 20%, 40%, 60% and 80%
replacement of natural coarse aggregate with recycled
concrete aggregate for multiple grades such as M40, M50 and
M60. Development of high-strength-durable concrete with
RCA for structural applications.
IV. METHODOLOGY
For the various mix proportions, the materials were used as
per standard specifications and its specifications given below.
Ordinary Portland cement 53 grade, from a single source
had been used throughout the investigation. The physical
properties of the cement which conformed to Indian Standard
IS 12269-2013 are listed in Table 1. The admixture used as
per IS 9103-1999. The natural coarse aggregate used in size
of 10mm and 20mm. with hammering on cube the RCA take it
out in size of 10mm and 20mm. Design mix to be carried out
according to IS 10262 - 2009 standards. Concrete cube
compression test performing as per IS 516-1959. Curing and
testing of concrete
specimens were performed
in college laboratory only.
