Concrete is most widely used in the construction industry and now-a-days Self compaction concrete is used because of its easy flow able properties and reduction in construction time. Self compacting concrete (SSC) is a basic type of concrete that does not required any kind of compaction or vibration. SCC was first developed by Okamura in Japan during the year 1980. This type of concrete flows easily around the reinforcement and into all corners of formwork and also it saves time, labor and energy. Different admixtures are used to produce effective self compacting concrete (SCC). The workability characteristics of SCC will be evaluated by the following tests like Slump Flow, V- Funnel, L-box Test. Many researches were carried out around the world with regards to different applications on properties and mix proportions. This paper includes the literature reviews related to behavior of self compacting concrete also deals with the strength and behavior of self compacting concrete using fibrous materials and mineral admixtures.

Septic system plays a major role in sanitary disposal activities. In developing country it is very essential for proper disposal of wastes for providing clean environment. In our country the government has adopted scheme, “CLEAN INDIA”,. For achieving this aim, the septic system is necessary to construct in each and every residential, commercial buildings and public areas. Septic tank systems are a type of simple onsite sewage facility.But groundwater pollution may occur and can create a problem. Usage of mobile septic tank can be helpful to avoid such problem. In this present investigation an idea has been arrived and the septic tank constructed by the way which have been tested for 10 days for decomposition using microbes. The term ‘septic’ refer to the anaerobic bacteria environment that develops in the tanks which decomposes or mineralizes the water discharged into the tank. The rate of accumulation of sludge is faster than rate of decomposition. So in our project we have used microbes for decomposition.In urban areas, construction of septic tanks are easier. But in rock exposures, the septic tanks cannot be constructed easily. In this paper, the problem is solved by giving an idea as solution by providing a “MOBILE SEPTIC TANK”. This will be helpful and eliminate such problems.
