Concrete is a standard building material used in construction, typically for foundations, and evidence of its use dates back to the construction of the Egyptian pyramids. Concrete mixes differ depending on the conditions that the end product will need to be able to withstand; from that point on, the perfect balance of ingredients can be determined and combined for the job at hand.
Buying concrete can be confusing when all of the different options are laid out, but concrete sales professionals can aid in identifying what additives and water content are necessary for any proposed structure.
Concrete is composed of different materials depending on the final intent of the structure. Typically, concrete consists of cement, ash, sand, chemicals and water, but other additives can be used to either make a stronger concrete or in some cases, a decorative concrete. A mix is created from those materials that can subsequently withstand the heavy loads of skyscraper foundations, housing foundations, or bridges and roads.
Aside from the basic cement and sand mix, the major components of water and chemicals aid in creating the correct mix for any job. Concrete has to cure in order to firm up and be a stable platform, and the water content is a key factor in the time required to properly cure and reach the appropriate strength rating. Chemicals can be added to speed the drying process, along with chemicals that can prevent corrosion, thicken concrete for slower pour rates, and even pigments to alter the color of the final product.
With all of these factors taken into consideration, finding the correct mix is essential for obtaining the proper strength in the final product. In the evolution of concrete over thousands of years, additives and chemicals have been discovered and mixed into the original formula to create concrete mixes that suit different purposes. Concrete sales can be confusing because of its many uses and forms, but understanding the end purpose for the materials and the requirements for workability helps to identify the properties required for the mix.
