Sakrete Lightweight Aggregate & Cement is a bagged structural concrete mix built around lightweight aggregate instead of normal stone. It is aimed at elevated slabs, walkways, steps, on-grade or suspended slabs, high-rise structural work and repairs where weight matters. Sakrete says it yields about 67% more volume per bag than standard concrete and is air-entrained for freeze/thaw resistance. Mixed as directed to ASTM C 387, it is rated above 4000 psi at 7 days and 5500 psi at 28 days, so it competes with standard bagged mixes on strength while cutting dead load.

This is a high-yield, high-strength mix of structural lightweight aggregate and cement. It is made for projects where weight is an issue, including elevated slabs and walkways, steps, on-grade or suspended slabs, and high-rise structural applications and repairs.
It gives 67% more volume than standard concrete and is air-entrained for improved freeze/thaw resistance. The mix has excellent workability. You can mix it in a mechanical concrete mixer or by hand in a wheelbarrow.
When used as directed and in accordance with ASTM C 387 Specification, the mix exceeds 4000 psi after 7 days and 5500 psi after 28 days.
