![]() ![]() These concrete blocks were so heavy that one person could not carry them on their own! Palmer designed the first hollow concrete block in the United States, and by 1900 Palmer patented his design. The recipe that Aspdin created is what we know as cement today-what he patented is known as Portland cement. In 1824, modern-day concrete was patented by British cement manufacturer, Joseph Aspdin. Roman architecture during this time required sturdy building materials, making concrete a great option for their infrastructure and buildings. The Romans used materials sourced locally to produce concrete. Historians even believe that the pyramids were constructed partially out of basic concrete.Īs early as 200 A.D., Romans were using concrete mortar. The earliest usage of primitive concrete blocks is attributed to the Romans, Greeks, and Egyptians. The use of concrete dates back centuries. When these ingredients are mixed together, a chemical reaction occurs and the result is concrete. The only aggregates used in concrete blocks are finely crushed stones or sand-like cement. Aggregates that are used to make both cinder and concrete blocks include:Īggregates are anywhere from 60 to 75 percent of all concrete and cinder blocks so it is important that these aggregates are clean, strong, and hard.Ĭoncrete blocks are composed of air, water, cement, and aggregates. Depending on the aggregate that is used, it affects the block’s overall strength. The type of aggregates that can be used in blocks varies. Concrete blocks have a higher percentage of cement in them than cinder blocks do. It’s rarely used on its own and it is typically used to bind the aggregates together. Cement is a binder that sets, hardens, and binds materials together. Concrete is a composite material that includes cement. ![]() The words ”cement” and “concrete” are frequently used interchangeably, but they are in fact different. However, there are some differences between the two blocks, the main being what type of aggregate is used in them and we’ll break that down further. The ingredients in concrete blocks and cinder blocks are relatively similar-water, cement, and aggregate. The Ingredients in Concrete and Cinder Blocks ![]() However, the ingredients and percentage of cement and aggregate differ between cinder and concrete blocks, resulting in concrete blocks being much stronger than cinder blocks and more useful for sturdier jobs. Both of these masonry blocks use the same three ingredients: water, cement, and aggregate. Concrete BlockĬinder blocks and concrete blocks are nearly the same thing. The reality is, there is very little difference between the two, and it really depends on what you’re using the blocks for. You may be wondering what the difference is between the two as you start your next construction venture. Cinder blocks and concrete blocks are both used by professionals and do-it-yourselfers for a wide variety of projects. ![]()
