Review on No Fine Concrete

The main objective of this project is to develop traditional or conventional concrete and simultaneously motivate the people about light weight concrete. This focuses on tests such as Compressive test only. The results obtained are interesting and useful to compare the results with that of traditional concrete. The main focus of this concrete is to low density and thermal conductivity, ultimately there Is reduction of dead load, faster building rate in construction and lessen haulage and handling costs. No-fine concrete is produced by using ordinary Portland cement, coarse aggregates, and water. This concrete is tested for its properties, such as slump value, porosity and compressive strength. The results showed that porosity has significant effect on compressive strength of no-fine concrete. The normal concrete has a density of 2500 kg/ m3, the major contributions to the density of concrete is the high specific gravity of coarse aggregate. In the present study, an attempt has been made to partially replaced coarse aggregate and fully replaced fine aggregate by lighter weight material to achieve concrete of lighter density. Coarse aggregate was replaced by blast furnace slag in various trial percentages.
