History Of Concrete

The History of concrete goes back to the Bronze Age. The Greeks used a natural substance called “limestone,” which they mixed with water and clay. They were not as advanced as other cultures in their concrete-building methods, but their technique proved to be quite successful. By the year 200 B.C., the Romans were perfecting the art of building with concrete. They began to use loose rocks and materials, as well as mortar and cosmetic bricks with cement. Then they developed hollow blocks. If you are looking for Grand Rapids concrete contractors call Grand Rapids Concrete Co at 616-344-5968.

The history of concrete can be traced back to 6500 BC, when the Nabataean traders developed a method to make a type of hydraulic cement. The Nabataeans used this material to construct buildings and other structures in a short amount of time. This technology was eventually used by the Romans for their aqueducts and underground cisterns. The Romans eventually modernized the process, and bonded the cement together with a gel created during the tamping process.

During the Roman period, concrete was used in buildings and civil engineering. Unlike the modern-day construction techniques, the Romans could withstand substantial weathering, earthquakes, and crashing waves. The first great project using this material was the Sebastos Harbor in 23 BC. This structure, which is nearly 2,717 feet tall, was commissioned by King Herod of Judea, who wanted to boost the economy of his kingdom. This was the first high-rise to be built using reinforced concrete, and the Burj Khalifa is the tallest structure in the world.

The ingredients used to make concrete are a mix of coarse and fine aggregates. These ingredients add strength to the material and are the main ingredient. These are sand, gravel, crushed stone, and recycled concrete. A fourth major ingredient is entrained air. The amount of air in the mix should range from one percent to nine percent. However, it’s important to add a higher proportion if you live in an area with freezing temperatures.

How Concrete Is Made

The process of making concrete is similar to that of making mud crafts. The mixture of sand, gravel, crushed stone and water will harden and create a paste. The proportion of water and cement will determine the strength of the concrete. The coarseness and fineness of the aggregates are important factors when creating concrete. The finer the aggregates, the more dense and solid the final product will be. To prevent this problem, coarse aggregates are generally smaller than 0.2 inches in size.

The first step in making concrete is blending the dry materials together. Once these materials are combined, the cement is added. Water is then added. During this process, the cement particles grow and link with each other and with the aggregates. When the water content of the concrete mixture is too high, the resulting concrete will be too weak. Engineers play with the ratio to make sure the mix is as strong as possible.
