Study of Concrete Modified With Artificial Cold Bonded Pelletized Light Weight Silica Fume Aggregates
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 4
Abstract
The recent advancements in the construction industry necessitate the development of new materials which have high performance than the ordinary conventional concretes. In the present scenario light weight aggregate has been the subject of extensive research which affects the strength properties of cement concrete. Light weight aggregate concrete has become more popular in recent advancements owing to the tremendous advantages, it offers over the conventional concrete but at the same time light in weight and strong enough to be used for. Lightweight concrete has been successfully used since the ancient Roman times and it has gained its popularity due to its lower density and superior thermal insulation properties. Compared with normal concrete, light weight concrete can significantly reduce the dead load of structural elements, which makes it especially attractive in multi-storey buildings. The most important characteristic of light weight concrete is its low thermal conductivity as this property improves with decreasing density. In this present experimental investigation an attempt is planned to be made to study the strength properties and the behaviour at elevated temperature of light weight aggregate concrete, with Silica Fume pellets is considered. The Silica Fume pellets are prepared by mixing silica fume with lime and cement as binders by using Pelletization machine. The variables considered are five percentages of silica fume aggregate replacing the conventional coarse aggregate i.e. 0%, 25%, 50%, 75% and 100% with 28 days curing period.
