Concrete Mix


Strong, Versatile and Durable Concrete  


The strength, versatility and durability of concrete makes it a very common building product. There are many different types of concrete from which to choose, and additives make a wide range of colors possible. Larger projects like driveways can be labor intensive, but smaller jobs like setting fence posts or mailboxes are relatively easy. Knowing how to handle concrete and which type is right for the job at hand will help you achieve the best possible results. Shop for concrete mix and concrete tools at The Home Depot.
 
As you shop for concrete mix, consider:
 
What is the difference between concrete and cement?
What types of premixed concrete are available?
How much concrete will it take to complete your project?
What steps can you take to ensure concrete safety?
 

Concrete and Cement


Concrete and cement are not interchangeable terms. Concrete is a mixture of sand, gravel, water and cement. Cement refers to the dry powder substance to be combined with other components that form various types of concrete once mixed together. The gravel component is sometimes referred to as crushed rock or aggregate. Mixing these ingredients in the right proportion is essential to producing durable, high-quality concrete.
 

Premixed Concrete  


There are a number of very useful, specialized premixed concretes readily available in case you do not want to mix your own concrete, that are a simple and economical way to produce the right concrete for any job. All you have to do is add the right amount of water. Once you know what type of concrete you want to use, take careful measurements of the area you’re working on to ensure you have enough concrete to finish the job.

Making your own concrete requires time and effort, but it can save you money. To make standard concrete, mix 1 part Portland cement, 1.5 parts gravel, 1 part sand with .5 parts water. Use water that is clean and free from acid, alkaline, sulfate and oil. Test consistency by using the back of a shovel to create a smooth surface. Then, use the side of the shovel to create a groove. If the surface remains smooth and the sides of the groove hold their shape, your concrete is ready.
 
If you cannot create a distinct groove, add more water. If the groove caves in, mix in more dry ingredients. Mixing concrete in a wheelbarrow provides an easy way to move it around the jobsite.
 

Safety


You'll want to take certain safety precautions while you work to avoid injuries such as back strain, or irritation of the eyes, skin and lungs. Concrete is caustic, meaning the chemical elements it contains have corrosive properties that can irritate or burn your skin if you come in direct contact with it. Knee pads will help you stay comfortable over the course of long jobs.
 

• Use a mask to filter out concrete dust and avoid working in poorly ventilated areas
• Wear waterproof gloves and boots to protect hands and feet
• Use your legs to lift heavy concrete to reduce strain on your back
