Production of self-compacting concrete (SCC) using local materials

Abstract

Nearly all concrete currently used in building and civil engineering construction requires compaction to achieve the required strength and durability. The prevailing method for compaction is vibration of the freshly placed concrete. However, vibration generates delays and over costs in projects. Moreover, it is a serious health hazard on and around construction sites. The main goal of the project is to develop a new vibration-free concrete to lower the overall cost (including technical and social costs) of in situ cast concrete construction. The project will focus on the mix-design process, taking into account properties of local materials. Thus, it will be possible to control the properties of the SCC at the fresh and the hardened stage and to minimise the cost of production. The use of self compacting concrete will: • Promote the development of a more rational concrete production • Accelerate the construction process • Significantly reduce the technical cost of in situ cast concrete construction • Improve the quality, durability and reliability of concrete structures • Improve health and safety on and around the construction site
