They are lighter thanks to the holes, which can be advantageous when wiring or running pipes through them. When creating boundary walls and other huge buildings, hollow blocks are employed, which have holes that occupy more than one-quarter (typically more than half) of its cross-sectional area. You would never want to attempt to walk on flooring with holes in it. Fully solid blocks are frequently utilised for paving operations and other tasks requiring stability and endurance. Solid Concrete Blocks vs Hollow Concrete BlocksĬoncrete blocks come in hollow and solid varieties, which are the two most common types used in construction. However, concrete blocks are more likely to slide and crack when the foundation shifts than bricks due to their higher moisture content and greater size. Concrete blocks are larger than bricks, thus the mortar joints holding them together need less cement to keep them together. Everything from the Roman Colosseum to the Chinese Great Wall was constructed with cement.Īn alternative to brickwork in construction, concrete blocks have both benefits and drawbacks. It is believed to have been found for the first time in what is now Israel and dates back roughly 12 million years. The formation of a type of naturally occurring cement from the interactions of limestone and oil shale actually marks the beginning of the history of concrete. Concrete is made by mixing water and cement, a powder made of limestone, clay, and other materials, into the mixture. About three 3 parts out of 4 of what we find in concrete are other materials, like sand, gravel, and stone. Concrete is created using cement as a component. Below, we'll go into more detail about the many varieties of concrete blocks, often called as CMU or concrete masonry units.Ĭoncrete and cement are also frequently used interchangeably. These two varieties of concrete blocks can be utilised for a variety of tasks in addition to wall construction.Īs you'll see, not every solid concrete blocks are completely solid, but they are more solid than hollow concrete blocks. Concrete blocks can be classified into two main types hollow and solid.
