Hallow concrete blocks are made of Portland cement and aggregate; high-density blocks may contain sand and gravel, whereas low-density blocks may contain industrial waste instead of aggregate.

Aerated concrete is used to make lightweight hollow blocks. The hollow concrete blocks are prepared, hardened, and cured before being transported to the job site, and they are a very durable and strong product.
