Abstract

Concrete is a versatile material and can be extended to applications requiring to perform in aggressive environments. In these environments, concrete should be highly durable for longer service life. The present thesis is an effort directed towards the achieving high performance in concrete by using RHA as supplementary cementitious material. To achieve high Strength in the concrete, it is necessary to have better understanding of the behavior of constituent materials. Thus, the behavior of RHA in concrete in terms of efficiency was assessed through the results available from literature. A mix design method was suggested and a wide range of concretes varying from 85-87Mpa with replacement levels varying from 0 to 15 Percentage were attempted. These concretes could be produced with the mixing, compaction, curing procedures conventionally used and with the available RHA. A maximum strength of about 86Mpa was obtained which compares well or was even better with the results reported hitherto in literature.
