Effect of Lightweight Aggregate on the Flexural Behaviour of Self Compacting Concrete Anand DEV BGa, Jayasree S. b. Abstract —SelfCompacting Concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight. Density of all types of concrete depends on the coarse aggregate .

THE VERSATILE LIGHTWEIGHT AGGREGATE MADE FROM POSTCONSUMER RECYCLED GLASS. Despite its low density, Poraver® is very resistant to pressure. It not only acts as thermal insulation but also absorbs sound, dimensionally stable over the long term, and resistant to fire, moisture and chemicals. Poraver® consists of recycled glass and is 100 % mineral.

The choice of aggregate is determined by the proposed use of the concrete. Normally sand, gravel, and crushed stone are used as aggregates to make concrete. The aggregate should be wellgraded to improve packing efficiency and minimize the amount of cement paste needed. Also, this makes the concrete more workable. Refer to Demonstration 3

Lightweight aggregate has a higher absorption than normal weight concrete. Because of this, prewetting of the aggregate is important, especially when lightweight concrete will be pumped. When lightweight aggregate is used in concrete, lightweight concrete results. The same batch plants and mixing procedures are used for lightweight concrete.
