Abstract: Due to the day by day innovations and developments in construction field, the global consumption of normal concrete is very high, which gives more self-weight to the structure. To reduce this self-weight lightweight concrete mixes are being adopted where weight saving is an important factor. Lightweight concrete is made by either omitting the fine aggregate from the mix (or) by replacing some (or) all the normal weight aggregate with light weight aggregate. Another way for making concrete light by inclusion of air.
In this experimental study we are going to study the compressive, tensile and flexural strength, durability properties of lightweight concrete which is achieved by eliminating the fine aggregate content. No-Fines Concrete is a method of producing light weight concrete by omitting the fines from conventional concrete. Concrete manufacturing involve consumption of ingredients like cement, coarse aggregate, water, chemical admixtures like WRA/HRWR, mineral admixtures like fly ash, ground granulated blast furnace slag (GGBS) etc. Coarse aggregate of size passing through 20mm and retained on 12.5mm is used. Using the above material lightweight aggregate concrete of M40 grade is being manufactured and tested against strength and durability properties. The Mix design is based on BIS method and the ingredients are batched on volumetric basis.
Keywords: No-Fines Concrete, GGBS, fly ash, compressive, tensile and flexural strength, durability.
