Concrete Stamping

Decorative concrete has becoming very popular amongst homeowners all over the world. In some parts of the world, they are just now starting to see it on driveways, patios, sidewalks and more.

In California it has been around for many of years. It started out with simply using tools to make impressions in the wet cement. (like cookie cutters) Now it has grown to many different patterns and ways of making a decorative finish including turning your old into new.

New concrete can be colored to almost any color you want by adding pigments to the concrete. The concrete can then be stamped or broom finished. Old slabs can be acid stained, overlayed, stained with colored sealers and splattered finished.

Concrete Stamps

There are different styles and types of stamps, when stamping first came out the stamps had thin impressions because most people figured if they were too thick or deep it would cause surface cracks. Since then they have started making them with some pretty deep grout lines.

 

 

Concrete is revered as one of the most durable construction materials known to man. However, without proper knowledge you may find that your next concrete project has failed to live up to your expectations. Cracks, discoloration, dusting, scaling, shrinkage, and blisters are just some of the problems that may occur if you do not begin with the proper concrete mix. In order to prevent many future problems, you need to ensure that you begin with the best concrete formula for your needs. You should also take the steps necessary to ensure that you have used adequate techniques to lessen the chance of future troubles. Once you begin to understand the science behind working with concrete, you'll find that you encounter fewer problems.

 

A combination of gravel, stone, sand, water, air, and cement are used to formulate concrete. The type of cement used is called Portland cement. Portland cement is comprised of limestone, and other ingredients such as shale and clay. The limestone and other ingredients are placed into a kiln and fired until it becomes fused. The result is known as a clinker and is the main ingredient in concrete. There are different types of Portland cement and each of these is used in various concrete formulas. Depending upon the nature of the construction, the project being completed, and the type of conditions the finished construction project will face, one of five types of Portland cement will be used to create concrete.

 

When cement and water are combined it creates a paste. This in itself does not form concrete. In addition to the cement and water, materials known as aggregates must be added to create a chemical process known as "hydration." When hydration occurs, the cement and water bond with the aggregates and become a solid form, or concrete. The process of hydration, as well as the selected aggregates, is vital to the process that formulates concrete.

 

Aggregates are the building blocks of concrete. They create the bulk of material that will enable the concrete to become a solid structure. Aggregates come in a variety of sizes. These include fine and coarse types. The combination of the aggregates used will determine the type of concrete that is formed after hydration takes place. Depending on the type of aggregate used, their location or the way they are distributed will have a direct effect on both the strength and density of the finished concrete. Because concrete can be both malleable or pliable as well as enduringly strong, concrete can be used to create a wide variety of buildings and structures.

 

When mixing concrete, it is imperative that you have the perfect proportions. If not, you'll find that the finished concrete will not be strong or durable. It is best to mix your concrete with about sixty to seventy percent aggregate, ten to fifteen percent should be cement, fifteen to twenty percent should be water, and between five and eight percent will be entrained air.

 

Since hydration is the key process that creates concrete, it may be surprising to discover that any type of water is fine for creating the reaction. However, when it comes to choosing aggregates, it is important that special attention is given to choosing the best ones for the type of concrete you are planning to make. When mixing concrete your objective will be to create good concrete that will then be properly cured. First, you will need to choose your type of Portland cement. As mentioned before, there are five types of Portland cement that are used for making concrete. The ASTM, or the American Society for Testing and Material governs the types of cement. They are Type 1, Type II, Type III, Type IV, and Type V.

 

Type I cement is a general or all purpose type of cement. It is the most common and used frequently for sidewalks, and masonry projects. It does not require special additives and takes about twenty-eight days to reach its full strength.

 

Type II cement takes longer to reach full strength than does Type I cement. Type II typically takes about forty-five days to reach full strength and is used for drainage structures. This type of cement is more resistant to sulfate than Type I cement and is recommended for areas that have higher sulfate concentrations.

 

Type III cement takes about one week or less to reach full strength. This type of cement is also more prone to cracking and shrinking, but due to its fast reaching strength, it is a good choice for many construction projects.

 

Type IV cement takes the longest time to reach full strength, usually reaching its’ maximum durability in ninety days or three months. Type IV cement is preferred for use in construction buildings or structures that are very large in size.

 

Finally, Type V cement provides the most resistance against sulfate and reaches full durability in sixty days, or two months. It is preferable for use in areas or locations that have very high sulfate concentrations. In addition to the five types of Portland cement there is another specially formulated cement that is used for creating concrete; air entrained cement.

 

Air entrained cement is used for pavements and other construction needs in cold climates as it is resistant to freezing, thawing, and scaling. Concrete that is used in freezing climates must be able to endure the harsh conditions as well as chemicals that are typically used to remove frost and ice. Sometimes the special mixture is added to Portland cement, types I, II, and III to increase their durability and ensure that they are freeze and thaw resistant.

 

Once concrete has hardened, it must be cured. The curing process is critical to ensuring that the concrete will complete the hydration process and reach its full level of hardness and durability. The curing process involves using moisture or water to ensure that the concrete hardens at its most durable form. It’s important to cure the concrete form with the method that is most appropriate for the climate. The water is added to ensure that the hydration process completes. Without water, hydration will not occur. By taking the time to ensure that you have the proper ingredients, mixture, and cure your concrete forms correctly, you can make certain that your concrete will be extremely strong and durable.
