INNOVATIVE CONCRETE PAVEMENT BY USE OF COARSE AGGREGATE
Abstract
An attempt has been made in this research to produce pavement concrete with innovative
coarse aggregate. Steel slag is a byproduct and waste material produced in steel industries. This kind
of solid waste material creates disposal problem and environmental effects. Demand of concrete
and consequently the aggregate demand was rising fatly. Hence, it is necessary to find other
substitute for aggregates. Experiments were conducted to determine the compressive strength,
Young’s modulus, flexural strength, Poisson’s ratio, Abrasion resistance and impact strength of
concrete with different percentage of steel slag aggregate. Pavement design is carried as per IRC:
58-2002.The results specify that with the rise in percentage of steel slag aggregate the strength
decreases when compared to the normal concrete, but at the same instant the strength satisfied the
grade (M40) concrete up to 50% replacement of steel slag. Increase of steel slag from 10% to
100% showsimprovement in Impactstrength as compared with normal concrete. However use of this
kind of materials in road construction, will reduce the cost of construction, leads to alternate the
conventional material and makes the environment pollution free.
