How is the strength of concrete measured?

How is the strength of concrete measured?

Concrete is one of the world’s strongest materials and comes in various strengths to meet a wide range of needs so how is the strength of concrete measured? At Doncaster Quickmix, we have been a leading supplier of concrete for many years. You can count on us to meet your concrete needs and supply the strength that you require. When you’re working on a construction project, you need to ensure the concrete that you’re using is tough enough to withstand the loads that it will be supporting. Concrete is measured by the weight it can withstand after being laid, cured, and dried for 28 days.

How strong is concrete? How is strength measured?

Concrete In Doncaster

Most people measure the compressive strength of concrete to determine how tough it is and how well it will withstand loads. Cylindrical concrete specimens are broken in a machine when compressive strength is tested. Compressive strength is measured in psi (pounds per square inch). Measuring compressive strength tells us whether a concrete mixture meets the requirements of a specific task. The higher the psi is, the stronger the concrete is. Stronger concrete does normally cost more, but it also has more longevity.

Typical strength requirements

Most projects require a minimum of 2,5000 psi. Concrete structures located in colder parts of the world require a higher psi. This is because they need to survive a larger number of freeze and thaw cycles. Concrete walls normally need a psi rating of 3,000 to 5,000 psi, with pavements requiring 4,000 to 5,000. Compressive strength is typically tested after a week and re-tested after four weeks. The American Concrete Institute has defined the highest strength of concrete as concrete offering a compressive strength of over 6,000 psi.

Tensile strength of concrete

Measuring the tensile strength of concrete tells us how well concrete can resist breaking or cracking when it’s under tension. If a tensile force is bigger than the tensile strength of the concrete, cracks are likely to form. Concrete often has a lower tensile strength than compressive strength. This in turn is why concrete structures facing considerable tensile stress often have to be reinforced with materials noted for high tensile strength. Steel is an example of this kind of material.

The role of water in concrete

Concrete is stronger when there’s less water in the mix. A strong concrete mix will have a low water-to-cement ratio alongside strong aggregate. Hydration enables concrete to reach its full strength. Cement and water must undergo this chemical reaction for high strengths to be achieved. 

Do you need to reinforce concrete?

Big construction projects often require steel reinforcing mesh. Reinforcement is also carried out using steel rods known as reinforcing bars. Sometimes, the mesh is used alongside these bars. Mesh and rebars don’t rust inside the concrete. This is because the curing of the concrete protects the reinforcements from oxygen. Not all concrete projects require reinforcement. The projects that do need steel reinforcement tend to be large ones. Cracking can often be prevented if the mesh is used to reinforce the concrete. Concrete slabs that are likely to face a heavy workload and lots of traffic are more likely to require reinforcement.

Common applications for concrete

Concrete DoncasterConcrete remains the most commonly used manmade material on the planet. As well as being used to construct roads and buildings, it is also used to build bridges, drains, pavements, and kerbs, as well as many other structures. The main materials used to create concrete include Portland cement, water, and aggregate. The aggregate can come in the form of rock, sand, and gravel. A workable paste is created when the materials are mixed together. This becomes harder over time. The material has remained popular around the world for several reasons. It has a long life and requires little maintenance. Concrete is also cheaper than many other materials used for construction projects. It can be shaped with ease before it hardens and it is non-combustible.
