Durability Performance of Locally Produced Self-Compacting Concrete.

      Аннотация: Self-compacting concrete (SCC) flows under its own weight thereby requires no ?compaction. One of its requirements is high cement content, making it a major ?contributor to greenhouse gases. To reduce the contribution to these gases and also ?harness the benefits of SCC, there is need for a portion of the cement, 'the culprit' to be replaced by locally ?available supplementary cementitious materials – limestone powder (LSP) and natural ?pozzolan (NP). LSP and NP have proven to be a very good filling agent and highly ?pozzolanic respectively, thereby improving the microstructure of the developed ?concrete. In order to study the feasibility of using the SCC with the locally available ?materials?, mechanical and durability properties of the produced SCC were tested. The ?results proved satisfactory and therefore furnished in the book.?
