Mix Proportion

In this paper, expanded polystyrene (EPS) lightweight concrete (LWC) was investigated. The mainaim was to design EPS LWC with the specified density of 1200 kg/m3 according to standard concretemix proportion. Mix proportion included total replacement of the conventional coarse aggregate bymaximum possible amount of EPS beads, which ensures concrete workability and prescribeddensity. The results demonstrated that exactly defined mixture-proportioning and casting procedureare required to achieve designed density. For designed EPS LWC mixture properties of freshlymixedconcrete and hardened concrete were analyzed. Based on test results it is concluded thatdesigned EPS LWC can be used for structural-insulating purpose such as floors and roofs.

The Stability

A country's advancement for the most part relies upon the advancement of transportation of the nation. As Flexible pavement is significantly used in India, it is significant that means must be taken to expand the life of the bituminous mix. Flexible pavement is frequently exposed to issues like rutting, cracking, and other failures due to repeated traffic loads. In this paper, the main aim of the study is stabilization of bituminous mix with CNSL and comparing the results with the conventional bituminous mix. The material used for the present study is VG-30 grade bitumen, CNSL, Lime and Natural Coarse Aggregate. In this research study, the CNSL as a replacement to bitumen by 2%, 4% and 6% and finally the stability of the bituminous mix and stability of the partial replaced bitumen by CNSL are compared by conducting Marshal Stability test.From the experimental investigation it has been proved that 2% addition of CNSL gave better stability and the flow value was higher for addition of 4% CNSL when compared to conventional mix.
