General
- Ready-mix
concrete (RMC) is a ready-to-use material, with predetermined
mixture of cement, sand, aggregates and water. RMC is a type of
concrete manufactured in a factory according to a set recipe or as
per specifications of the customer, at a centrally located batching
plant.
- Ready-mixed
concrete’s ubiquitous use as a building material is largely because
of two advantages. It is cheap. It also allows great diversity in
design and function, because in its fluid form, it can be poured
into molds of any shape.
Process
- The raw
materials (sand, aggregate, cement) through automatic the mixing
machine become ready-mixed concrete.
- Ready Mixed
Concrete is manufactured under computer-controlled operations and
transported and placed at site using sophisticated equipment and
methods.
Technology
- Ready-Mix
Concrete (RMC) offers high-tech solutions to the needs of the public
works and construction industries. It allows these industries to
build ever-longer bridges, ever-higher buildings, tunnels, dams,
etc.
- The basic
process for making ready-mixed concrete has not changed for the past
60 years: dry raw materials are measured, loaded into a bin, mixed,
placed into a truck, and water is added (sometimes the order of the
last two steps is interchanged).
Market
- The RMC
market, which has grown from 2.65 lakh cubic metre in the first half
of 2002-03 to 3.99 lakh cu.m in the corresponding period of the
current fiscal, will be the "segment to vouch for in the future.
- The growth of
RMC is predominantly driven by demand from the metro cities. In
cities like Mumbai, the mandatory use of RMC is in construction of
flyovers provided the requisite impetus to growth, according to an
ICRA analysis. RMC is particularly useful when the building activity
is located in congested sites where little space is available for
siting the mixer and for stock piling of aggregates. The use of RMC
is also advantageous when only small quantities of concrete are
required or when concrete is to be placed only at intervals.
- The
ready-mixed concrete industry’s faster-than-average growth in total
factor productivity has been reflected in real ready-mixed concrete
prices. The ready-mixed Bureau of Labor Statistics PPI index saw
average annual price growth that was 0.2 percentage points lower
than annual CPI growth over 1958-2006
