Normal weight or lightweight concrete
Did you know?
WebLightweight aggregate: Lightweight aggregate is often defined as any aggregate with a dry loose bulk density of less than 1200 kg/m 3.Lightweight aggregates are used to produce lower density concretes, which are advantageous in reducing the self-weight of structures and also have better thermal insulation than normal weight concrete. Web8 de jun. de 2009 · An important question always is how much this will cost. Lightweight aggregate concrete is about $20 to $30 per cubic yard higher than a normal weight mix. For internal curing, you may only be replacing about a third of the aggregate with lightweight so it may only add an extra $10 per cubic yard.
WebFurthermore, wastes can be utilised to generate lightweight concretes. In this article, a variety of studies conducted by researchers to develop lightweight concrete by employing a variety of feasible light weight aggregates are addressed..
