Strength of Concrete (PSI)

Concrete Strength: What is the Compressive Strength of Concrete? The strength of concrete is measure in terms of pounds per square inch (or PSI). PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression. 1.) 2500-3000 PSI Most concrete has a PSI rating of 2500 to 3000.

Concrete mixer

A concrete mixer is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works, portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens. An alternative to a machine is mixing concrete by hand. This is usually done in a wheelbarrow; however, sever

How to Order Concrete

A concrete contractor usually gets the concrete delivered to the site at the proper water to cement ratio (because the plant won’t send out a knowingly defective product), and then the contractor adds water to achieve a more plastic or workable mix.

Quick Cure

Curing is a process by which a gel is formed to “glue” all of the ingredients together. Curing is more than simply hardening of the concrete. Fully cured concrete results from a chemical reaction (known as hydration) between the water and cementitious ingredients of a concrete mix. During this hydration process, calcium silicate hydrate ...

Concrete Driveway Construction - Thickness, Rebar & More

Apr 07, 2020 · Thickness is the major factor (even more than the strength of the concrete) in determining a driveway's structural capacity. Place concrete at a minimum thickness of 4 inches . Increasing the thickness from 4 inches to 5 inches will add approximately 20% to your concrete cost, but will also boost your driveway's load-carrying capacity nearly 50% , according to the Tennessee Concrete Association.

Testing Pervious Concrete| Concrete Construction Magazine

The container is filled with pervious concrete in two equal lifts and each lift is compacted by 20 blows with a Standard Proctor Hammer. The pervious concrete is then struck off flush and the bucket is weighed both with the pervious inside and empty. The concrete's weight is divided by the volume (multiplied times 4) and the result is the density.

Ready-mix concrete

Concrete has a limited lifespan between batching / mixing and curing. This means that ready-mixed concrete should be placed within 30 to 45 minutes of batching process to hold slump and mix design specifications in the USA, though in the UK, environmental and material factors, plus in-transit mixing, allow for up two hours to elapse.
