In this paper self compacting concrete (SCC) is prepared using different size of aggregate i.e. using maximum size of aggregate (MSA) 20 mm and 10 mm. The packing of aggregate depends on the grading of aggregate, and therefore different aggregate size results in different packing. If packing of aggregate is more, paste available for flow will be more. So in present study SCC mixes are prepared keeping paste volume and aggregate volume constant but varying the fine aggregate (FA) and coarse aggregate (CA) proportions in total aggregate. Various such blending of FA: CA like 60:40, 55:45, 52:48 are taken for both only 20 mm MSA and only 10 mm MSA. Total 6 different combinations are tried to check effect of packing of aggregates on the fresh and hardened properties of SCC. It is observed that higher packing density results in higher slump flow. Compressive strength, Slump flow and T500 time of SCC mix are checked and presented in this paper.

—Cold formed steel sections are extensively used in Industrial and many other non-industrial constructions in World wid. It is relatively a new concept in India. So, here in this research, an attempt is being to carry out the comparison between hot rolled and cold formed steel sections. The results shall be checked with the ultimate goal of reducing the tonnage. Structural analysis and design shall be carried out in STAAD.Pro.V8i SS6 by Bentley systems because of its strong analysis engine, easy graphic user interface and universal acceptability.

It is proven that fines are important constituent to produce self compacting concrete (SCC). Comparing to conventional concrete more fines are added in SCC. Cement, fly ash and any filler material finer than 125 micron are considered as powder or fines. Amount of fines affects the fresh and hardened properties of the self compacting concrete. Fine aggregate used in the production of concrete also has some fines in it. In this paper effect of sand fines on fresh and hardened properties are investigated and presented. SCC mix were prepared by varying sand fines content from 6.9% in sand to 0 % and all other mix constituent were kept constant. Fresh properties like slump flow, T500 time and hardened properties like compressive strength were found.
