Question: We're thinking of developing a 6inchthick precast concrete residential wall system made with lightweight aggregates. For good insulating properties we want a low density and high Rvalue, but we also need to reach an adequate compressive strength. How are concrete density, Rvalues, and ...

Lightweight Insulating Concrete. Microphoto showing pumice vesicles. It's the naturegiven physical makeup of pumice—essentially a foamed stone—that gives pumice concrete both its light weight and insulative qualities. PUMICE CONCRETE (not to be confused with PumiceCrete®) is composed of Portland cement, pumice rock, pumice sand, pumice ...

May 09, 2018· Lightweight concrete may not be as structurally sound as traditional concrete, but it can be useful in some projects where weight is more important than strength. To make this concrete, combine 8 parts cement, sand and lightweight aggregate with 5 parts water.

The use of lightweight concrete dates back to as early as the eighteenth century, and as advances in building and construction technology have increased, so has the use of lightweight concrete as the benefits of lighter dead load concrete have become apparent.

Lightweight concrete instead uses a variety of alternate aggregate materials that may include more porous rock like pumice, manufacturing byproducts like fly ash or slag, or clay, shale or slate that has been treated with a heat process that expands the material and …

Lightweight Concrete. Lightweight concrete, weighing from 35 to 115 pound per cubic foot, has been used in the United States for more than 50 years. The compressive strength is not as great as ordinary concrete, but it weathers just as well.

Litecrete lightweight precast concrete is manufactured using local pumice aggregate. The pumice provides both inbuilt insulation and a 40% weight reduction compared to standard precast concrete. The product can be used in both residential and commercial construction.
