The damp concrete mixture is poured into the mold, then pressed down into the mold by a weighted arm. The mix design used in manufacturing concrete blocks contains very little water since this is best for production.Ĭoncrete bricks are made in a brick press mold. Modern brick plants typically include water-reducing admixtures in the mix design, enhancing the block’s strength. What is a concrete block?Ĭoncrete blocks are made of cement, water, and aggregate (sand and stone). These robust building blocks are the mainstay of many large construction projects. Concrete BlockĬoncrete blocks are available in many shapes and sizes. Here, the hollows in the cinder block are often filled with reinforcement to enhance its structural integrity and longevity. Instead, they are used for lightweight applications, such as garden walls and creating raised garden beds. Since cinder blocks aren’t as robust as concrete blocks, they’re no longer used for weight-bearing construction projects. This high absorptivity is another reason for not using them to construct building walls – waterproofing the structure will be a potentially costly exercise. This means they can absorb far more water, further weakening their structure. These blocks are often categorized as lower-grade concrete blocks and are never used in weight-bearing applications.Ĭinder blocks are more porous than their concrete counterparts. Additional reinforcement and filler material are often added to this core to increase stability and strength. This makes them prone to warping, bending, or buckling under load, which requires expensive repairs.Ĭinder blocks are available in various shapes and sizes and typically have a hollow core. These blocks are far lighter than concrete blocks and aren’t very robust. What is it made of?Ĭinder blocks are made of cement, water, and a generous portion of coal cinders, hence the name. 3.4 Which is better for the foundation?Ĭinder blocks are old-fashioned construction units, pre-dating the concrete blocks we’re familiar with today.3.1 Strength: Which is stronger, cinder block or concrete block?.
