What is the lightest type of concrete?

Types of Lightweight Concrete

• Lightweight Aggregate Concrete. Ad.
• Aerated Concrete. Aerated concrete has the lowest density, thermal conductivity and strength.
• No Fines Concrete.

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.

What does Lightweight concrete weigh?

While normal-weight concrete mixes typically weigh 145 to 155 pcf, lightweight concrete typically weighs 110 to 115 pcf. Structural lightweight concrete commonly has 28-day compression strengths comparable to normal-weight concretes.

Is lightweight concrete cheaper than normal 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.

Does light weight concrete crack?

A new report by the Virginia Transportation Research Council in the USA has shown that lightweight concrete decks exhibit fewer cracks than their conventional counterparts. “These properties tend to reduce cracking in the concrete and are highly desirable in bridge decks,” said the report.

Can you nail into GypCrete?

As gypcrete is more brittle and has lower compressive strength, it won’t hold the nail at all.

Is gypcrete lightweight concrete?

Since gypsum concrete (GypCrete) properties are designed for interior usage, lightweight concrete cementitious properties are better for exterior usage. The mixture creates lightweight concrete with a density between 20 to 120 pcf, which allows for even pours over exterior surfaces.

What can be made out of lightweight concrete?

Our lightweight aerated concrete ornamentation products can be produced in a wide range of finishes, such as marble, sandstone, slate of any color. The product range includes columns, bench tops, ledges, arches, tiles etc – anything which can be cast in molds.

What are the applications of litebuilt lightweight concrete?

The multitude of applications for LITEBUILT® lightweight concrete include: aerated lightweight concrete blocks and lightweight tilt-up panels, foamed concrete floor screeds, sound and thermal insulation, geotechnical and ornamental concrete applications.

What is the density of structural lightweight concrete?

What is Lightweight Concrete? Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).

Why do they use lightweight concrete in Mexico?

In Mexico we have a saying that “we build our homes so we have to go outside in the summer to be fresh, and in the winter we go outside to catch the rays of sun to be warm”. Lightweight concrete can help this situation by making available materials for more comfortable homes.
