Cost Implications of Lightweight Concrete The material unit cost of lightweight concrete is typically higher than that of normal-weight concrete, but the unit cost usually is more than offset by the overall reduction in concrete volume and steel tonnage for the structural system.

How much does lightweight concrete cost?
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.
Is lightweight concrete cheaper than normal concrete?
In contrast to traditional concrete, lightweight concrete has higher water content. ... As a result, many believe normal concrete to be cheaper compared to LWC. However, projects made with normal concrete require additional material for framing, cladding, and steel reinforcements – ultimately increasing the overall cost.
What are the disadvantages of light weight concrete?
Disadvantages of Lightweight Concrete:
The only disadvantage of Lightweight Concrete is that the depth of carbonation that is, the depth at which corrosion can occur within the right conditions is almost twice that of conventional concrete.
What is lightweight concrete used for?
Structural lightweight concrete has been used for bridge decks, piers and beams, slabs and wall elements in steel and concrete frame buildings, parking structures, tilt-up walls, topping slabs and composite slabs on metal deck.
