Important Concrete Mixing and Purchasing FactorsThe Basic Ingredients All concrete consists of four basic ingredients; Portland cement, sand, gravel or crushed rock, and water. The intended purpose of the concrete will dictate the proportions of these ingredients. A reliable concrete contractor or ready mix concrete producer will be knowledgeable about which mixing ratio will be proper for any given project. Concrete Mixing Almost every ready mixed concrete producer offers a warranty that concrete will cure to a specific density and hardness. Be sure to get a guarantee in writing in the event of a faulty batch requiring removal and re-pouring; provided at the producer’s expense. Which Purchase Option is Best for Me? Cost is another important factor for homeowners planning a project involving concrete construction; including concrete flooring, a concrete driveway, or a concrete patio. Skyrocketing concrete prices have necessitated many homeowners to consider handling concrete pouring for large-scale projects themselves. Concrete for any concrete masonry project can be purchased in one of several ways: * Premixed bags of dry concrete mix – just add water according to instructions on the bag. For large projects such as a concrete floor, this may be the most expensive way to purchase concrete. However, for small projects such as setting fence posts, this may be the most economical means. * Delivered ready mix concrete – a good option for large projects. Brought right to the job site, wet and ready to pour in a cement mixer truck. Expect to pay a delivery charge as well as a premium price per cubic yard of product. Shop competitors for the best price and warranty. * Haul-it-yourself ready mix concrete – an option offered by some ready mix producers. Can be a good money-saving option. However, you will need the means to haul it; trailer mount mixers are available for rental. Shop competitors for rental and concrete prices. * Portland cement – purchased in bulk to mix with the other ingredients at the job site. This may be the most cost-effective way for a large project, but keep in mind you will need a concrete mixer. You will also need to know how to mix Portland cement using the proper ratio of other ingredients required.
