Concrete blocks are made from the same ingredients used in poured concrete walls -gravel (called aggregate), sand, Portland cement and water. Lightweight blocks are sometimes called cinder blocks because fly ash (cinders), a waste product from industrial combustion, is used as a partial substitute for heavier ingredients like sand and aggregate. The hollow cores in most CMUs make the block more economical and easier to handle. The cores can be filled with concrete, sand or foam insulation to improve strength, thermal mass or insulation value.
Contrary to popular opinion, a Hudson block foundation isn’t inferior to a poured concrete foundation, providing that it’s been properly built. Both types of masonry require steel reinforcement and must be laid on a strong, stable footing. Good drainage and damp proofing details are essential.
