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. Web1 de jan. de 2004 · ACI 213 goes on to note that the abrasion resistance of structural lightweight concrete can be improved by combining the lightweight coarse aggregate with a hard fine aggregate or by applying a natural sand-portland cement or iron-aggregate dry shake to the surface of the concrete.
