Investigation on Self Compacting Concrete Utilizing Recycled Brick Aggregates and Steel Fibers
摘要
Self-compacting concrete (SCC) is virtually entirely deaerated while it flows in the form work and can flow and consolidate under its own weight. It is sufficient to fill the areas of all shapes and sizes without causing bleeding or segregation. Because of this, SCC is especially helpful in places where total compaction is not feasible. The concrete gets fail mostly, as a result of faulty concrete compaction. To avoid this type of problems self-compacting concrete is the best solution. Numerous studies have been conducted in SCC using waste recycled aggregates. The purpose of this research is examine the compressive, tensile and flexural characteristic of SCC added with Recycled Brick Aggregates (RBA). In order to find the correct combination proportion, several testing were carried out on the properties of SCC in its fresh condition employing mix proportions, adjusting the percentage of RBA and Steel Fibers (SF) in addition to acceptable dosages of Super Plasticizer (SP). In the result it was observed that flexural strength of SCC was increased at 0.5% addition of steel fibers and 25% coarse aggregate replacement with RBA.
