What Kind Of Concrete Can I Have Delivered?
Any! Fulford & Jones, Inc. uses volumetric concrete mixers that can pour a wide range of concrete, from residential concrete for driveways to flowable fill for utility projects. If you’re unsure what your project needs, contact us today.
How Do I Know If I’m Ordering The Right Concrete?
- The concrete’s use, such as a driveway or commercial parking lot;
- The amount of concrete needed to complete the project;
- Whether the concrete needs admixtures [or additives]; and
- Worksite accessibility, such as a gate code.
How Do I Know How Much Concrete To Order?
How Long Can The Concrete Stay In The Mixer Before It’s Poured?
Because we use volumetric concrete mixers, the concrete doesn’t mix until we — or you — say to mix it. All concrete mixes fresh on-site then pours within minutes. It also allows us to change the mix design for another area without leaving then returning, which may unnecessarily hold up project work.

What’s The Difference Between Cement & Concrete?
While many people use these terms interchangeably, there are differences between them, and concrete being the correct term for itself.
One of several ingredients in concrete, cement is a powder comprising 10 percent to 15 percent of the mix by volume. A paste forms when water is added, triggering a chemical reaction known as the hydration process.
It is the by-product of the hydration process between the cement powder and water, which then bonds with the aggregates.
Why Does My Concrete Change Color The Next Day?
A color change generally means the concrete is undergoing the curing process, with the material taking on a lighter color.
Can The Temperature Affect My Concrete?
Yes! The chemical reaction needed to hydrate the cement is temperature-sensitive. If the air temperature is near or below 32°F, then:
- The cement won’t hydrate at a fast enough rate;
- The water used in the concrete may freeze; and/or
- The concrete won’t set and develop its designed strength.
On the other hand, temperatures above 90°F generally cause:
- Rapid cement hydration;
- Premature concrete setting, which inhibits proper placement and finishing.
Ideally, temperatures will be between 50°F and 85°F for concrete placement.
How Does Concrete Gain Strength?
It initially gains during the hydration process as water and cement blend together then continues as the concrete cures in subsequent days. Final compressive strength is generally measured after 28 days.
My Concrete Has Stains — How Can I Get Rid Of Them?
Depending on what the stain is, either a particular chemical or water mixture is used to dissolve it for removal.
A variety of means are frequently used, such as flame cleaning, grinding, planing, sandblasting, scabbling, and shot blasting.
