Abstract
Self-compacting concrete which does not require external compaction because it becomes levelled and compacted under its self-weight. This study is focused to investigate the durability parameter of self compacting concrete produced with value obtained with trial done, optimum of 12.5% of the cement (by mass) replaced by fly ash and dolomite powder. For these mixtures compressive strength (cube) will be studied at the age of 43,58,73,88 days with same water powder ratio (0.45). Also tested for durability properties like, water absorption, sulphate attack, chloride attack, acid resistance and sorptivity test. Superplasticizer like polycarboxylic ether (PCE) are used to improve the workability and durability characteristics. The cement replacement concrete achieved superior performance in the fresh and mechanical tests should be compared with the conventional concrete.
