Concrete provides the foundation for most construction projects. But what makes this aggregate so reliable, and how is its strength measured? If you’re about to place an order for recycled concrete, here’s a guide to help you learn which type is best for your project.

What Is PSI & How Does It Relate to Recycled Concrete?

PSI stands for pounds per square inch and is used for measurements such as tire pressure and wastewater flow. It’s also used to determine how much pressure hardened concrete can withstand before breaking. Normally, concrete ranges between 2,500 and 5,000 PSI. However, some engineered varieties can reach 10,000 PSI or higher. 

Which PSI Is Right for Me?

Therefore, most contractors use concrete mixes with a 2,500 PSI. Since such recycled concrete is lower in strength than other types, it’s also less expensive.

For general construction, contractors stock up on 3,000 PSI concrete. However, when constructing the foundation of a home or building—which must withstand the weight of the entire structure and the objects inside it—they’ll need 3,500 PSI concrete or higher. Driveways, bridges, and other areas that might need to support large loads—such as heavy-duty construction vehicles, RVs, or dumpsters will need 4,000 to 5,000 PSI concrete.
