| Abstract: | Large quantities
of waste materials and by-products are generated from manufacturing processes,
service industries and municipal solid wastes. As a result, solid waste
management has become one of the major environmental concerns in the world. This paper presents a laboratory study to advance a step-wise
procedure to proportion plain and slag concrete mixes with burnt coal cinder
waste as coarse aggregate. When coarse aggregate characteristic strength is
lower than the concrete strength required, conventional methods such as British
Method, ACI or any standard code cannot be used directly. From the observation
of failed samples, it is evident that failure of the sample is predominantly by
aggregate crushing than usual bond failure observed in the case of conventional
crushed aggregate. To analyze the data, concrete is regarded as composite of
cement mortar matrix and coarse aggregate. With the concrete and matrix
strengths and their respective volume fractions as input parameters, the
characteristic strength is determined from linear law of mixtures. Using again
the same law, the matrix strength required to realize higher or at par strength
to that of the characteristic aggregate strength is calculated. To arrive at
water-cement ratio for matrix strength the generalized Abrams’ law is employed.
