12 in. x 8 in. x 16 in. Hollow Concrete Blocks
The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 38-43 lb (17.2-19.5 kg). In general, the concrete mixture used for blocks has a higher percentage of sand and a lower percentage of gravel and water than the concrete mixtures used for general construction purposes. This produces a very dry, stiff mixture that holds its shape when it is removed from the block mold. With a variety of sizes, in both hollow and solid shapes, concrete blocks are an ideal material for building projects or as supports for a host of uses.
