Write a 10 page essay on PRODUCING SELF-COMPACTING USING WASTE MATERIALS.

Self-compacting concrete are considered as “the most revolutionary development in concrete construction for several decades” (EFNARC). The idea of SCC originated in Japan and has been adapted to other nations such as Europe. The development of SCC is an economic approach to offset the increasing lack of skill labour. It contributes to the economy such that it offers faster construction, easier placing, reduction of manpower on site, offers flexibility in design, improved durability, better surface finishes, thinner concrete sections and safer working environment. SCC is a practical application for the construction site work and the precast concrete works.

The test for the self-compactability of the SCC measures its quality. The contributory factors include, the influence of coarse aggregate depending on spacing size, the role of mortar as the fluid in flowability of the fresh concrete, the role of mortar as the solid particles, and the influence of the coarse aggregate regarding the shape, grading and content. The employment of SCC is beneficial to construction because it eliminates the vibration noise as well it is cost-efficient for the cost of vibration compaction. The wide use of the SCC is an innovation in the concrete construction technology such that the SCC are reliable, durable concrete structures with minimum maintenance requirement (Okamura, and Ouchi, 2003).

The development of SCC as a solution to the labour scarcity offered benefits to the structural concrete industry as it develops higher quality concrete with optimum workability and overcomes problems related to dust and noise. The workability property of the SCC is achieved primarily due to the high content of fine aggregates and the chemical mixtures. Various relevant studies are now introduced into the construction industry promoting the use of recycled materials for applications of SCC. This innovation is practically new, where standards of SCC with made up of recycled materials
