Cement and concrete are not the same thing, but concrete does have cement as a primary ingredient.
In its most basic form concrete is made of cement, water, sand, and stone. Cement is a very fine powder made from limestone, sand, clay, and iron ore. In the right proportions these ingredients are crushed and super-heated in a kiln to form "clinker". The clinker is crushed again with the correct amount of gypsum and other ingredients and the result is a fine powder that we call cement.The strength of concrete comes from the reaction between water and the chemical compounds in cement referred to as hydration. The aggregates in concrete (sand and stone both coarse and fine) serve to add volume only and are not active ingredients in the hydration process.
Schuster Concrete ships what we call Ready-Mixed Concrete. When you place an order for concrete we match your requirements with a specific mix design from our database. The mix constituents are sent to batch panels that load all the raw materials into a drum which mixes the concrete. By the time the truck arrives at your job the product is sufficiently mixed and ready to pour. Each load is custom made for your application according to a specific mix design only moments before the truck leaves for your home or job. The batching of the raw materials in their specific quantities is done by computer, guaranteeing accurate products and reproducible mixes.
Concrete is one of the most versatile building materials used in construction today. In the 1960’s concrete construction challenged steel structure construction in the United States. Rather than large steel girders and steel decking, reinforced concrete was used to make building columns and decks in high rises. This economical building method is used more than ever today.
Part of the versatility of concrete is its wide availability and wide range of applications. In addition to large building construction, concrete is often used in residential applications for driveways, house foundations and walls, as well as many others. Concrete is often used for paving and curb and gutter applications. Precast concrete refers to the process of filling pre-made molds with concrete to produce a variety of things such as drainage piping or underground vaults. Tilt-up concrete construction is a building process often used in large warehouses with a large flat floor and semi-identical wall sections. Construction crews pour a large flat floor then spray a non-stick film onto the floor. The wall sections are actually formed on top of the floors and "tilted up" into place using a crane.
The reaction between water and cement gives concrete its strength. The important water-to-cement ratio is responsible for the strength of the finished product. Concrete strength is usually measured by its compressive and flexural strength in Pounds per Square Inch (PSI). When you order a "Bag" mix you’re really ordering a specific quantity of cement per cubic yard of concrete. Using some conversion factors you can translate between the two.
It takes time for concrete to achieve its full strength. They say that the innermost concrete poured in the Hoover Dam is still hardening to this day! Often concrete is measured for strength at intervals of 7 days, 14 days, 28 days, and sometimes 56 days. We assume that the 28 day strength test will be an accurate measurement of the final strength of the product.
Your account representative can help you determine what strength of concrete you need. As you can imagine, cement is a costly material in the production of concrete. We tailor specific mixes to specific applications so that you can successfully accomplish the goals of your project in an economical way.
Weather conditions are often the enemy of concrete. Extremely hot dry weather causes concrete to set up very quickly, making it difficult to place and finish. Extremely cold weather can cause the top layer of concrete to freeze and flake off, often ruining hours of hard work and thousands of dollars worth of material. Rain can make concrete difficult to finish as the rain washes away the smooth creamy layer that finishing trowels bring to the surface, exposing the aggregate. That’s a lot to worry about. Thankfully, extra products can help.
During the summer months you can also substitute ice for a percentage of water in the mix in order to lower the core temperature of the concrete and slow the hydration rate. This helps counteract the effects of the air temperature and the heat contained in the raw materials. Ask your account representative about adding ice to your mix.
During the winter months we substitute regular water with heated water to increase the core temperature of the concrete to prevent freezing and allow more time for the hydration process to take place.
Concrete inherently contains entrapped air of less than 3% by volume as a result of the mixing process. Air Entraining Admixtures are used to entrain air contents of 4-8% by volume of concrete. Entrained air is necessary to protect concrete that is exposed to freeze/thaw cycles in a saturated state. These microscopic entrained air bubbles capture water and allow it to freeze and thaw without deteriorating the concrete.
Retarder is used to decrease the hydration rate of cement, thus giving you or your contractor more time to place and finish our products before the concrete begins to set. Retarder can be well worth your additional investment. It provides an added measure of workability and reduces the rate of heat increase produced by the hydration process. Consider adding retarder on hot, dry days to slow the set rate, allowing for a better finish. Also consider adding retarder if you need more than 30 minutes to unload the truck (i.e. if you’re going to be using buckets or wheelbarrows to transport the concrete from the truck to your work area). By adding retarder to your mix you can expect to retard the set time by 1.5 hours to 8 hours depending on the dosage that you order. You can use retarder for just about any concrete application.
Water reducers are often used to increase the workability and the strength of concrete. It makes concrete "wetter" without adding water. If you’re pouring plain concrete and find that it’s difficult to place or pump, you may be tempted to ask the driver to add additional water to the mix. Beware that by adding water you could be reducing the compressive strength of the finished product. If, however, you choose to add a water reducer, you can expect a more workable product with the benefit of needing less water to make it "wet". The result is a high-strength mix that can be pumped at a 4"-6" slump. You can also achieve a strength gain over traditional concrete when poured at the same slump.
Your account rep can suggest an appropriate dosage if you’re interested in adding water reducer to your mix.
Accelerators are often used in cold weather to speed up the setting time of concrete. In cold weather it’s often helpful to add accelerators to speed up the cement hydration therefore increasing the initial set of the concrete. Always take great care when pouring concrete in cold temperatures. You’re account rep or salesperson can help you determine the appropriate amount of accelerator for your application.
Accelerators can also be used in high-early mixes, or mixes that require high strength in a short amount of time. Concrete contractors on high rise projects often use high-early mixes when pouring columns and decks to produce enough strength in 7 days to pour the next elevated deck and columns rather than waiting for 14 or 28 day compressive strength. This facilitates the rapid building schedules that general contractors often require.
Concrete itself is a relatively safe material with which to work, however, the delivery and placement of concrete can have some inherent dangers. You can mitigate most risk by taking a few simple precautions:
