Frequently Asked Questions

1. Will the color of the concrete change as it cures?
2. What is a slump?
3. What is a tamp used for?
4. How long does it take for concrete to dry enough to walk on?
5. How long does it take for concrete to cure enough to drive on?
6. Should I put cure or water on the concrete?
7. Do I need base course for subgrade?
8. What is a control/construction joint and where are they needed?
9. What is an expansion board and where are they needed?

Will the color of the concrete change as it cures?

Yes it will become lighter as it cures.

What is a slump?

The slump refers to the consistency of the concrete. (how wet or dry the mix is)

What is a tamp used for?

A tamp is used to blend the aggregate downward into the mix and bring the “cream” to the top. The use of a tamp will provide a more workable mix and allow for a proper finish.

How long does it take for concrete to dry enough to walk-on?

Wind, humidity, and sunlight are all factors in how long it takes for concrete to dry.

How long does it take for concrete to cure enough to drive-on?

Again, wind, humidity, and sunlight are all factors but the standard is 5-7 days.

Should I put cure or water on the concrete?

Yes, after the initial 12 hours, applying cure or water for 5 days every morning and night is recommended.

Do I need base course gravel for subgrade?

Only if you are raising the elevation of the pour. The base course gravel will need to be compacted.

What is a control/construction joint and where are they needed?

It is a groove joint used to control concrete cracking. They are needed no more than 1.5 x the width.

What is an expansion board and where are they needed?

It is material placed in the concrete to allow for expansion and contraction of the concrete. They are needed if you have 2 sides that are constricted, parallel, and it is also recommended if you have 3 sides combined.

Glossary of Concrete Terms

Accelerator – Chemical substance added to a concrete mix that reduces the set time by increasing the rate of hydration.

Aggregate – Concrete is a mixture of water, Portland cement, and aggregates (sand and / or stone). Sand is considered a fine aggregate, while any stones are coarse aggregates.

Bull Float – a tool comprising a large, flat, rectangular piece of wood, aluminum, or magnesium usually 8 inches wide and 48 inches long and a handle 4 to 16 feet in length used to smooth unformed surfaces or freshly placed concrete.

Cubic Yard – Unit of measure for ready mix concrete. Concrete is ordered, sold, and batched by volume.

Curing – The maintenance of the proper moisture and temperature of concrete is its early stages that desired properties may develop.

Portland cement – A hydraulic cement that sets and hardens by chemical interaction with water.

Sack mix – The amount of sacks of cement in a cubic yard of concrete. Specified when ordering, concrete is typically referred to as a 5 sac mix. The sacks of cement needed in a mix are usually specified in either the plans or the specifications of a project. More sacks = more strength.

Screeding – The operation of forming a surface by the use of a screed or strike-off and screed guides. (typically, the forms)

Set time – A measurement in hours and minutes of the hardening of concrete to resist a measure of penetration.

Slump – A measure of consistency of freshly mixed concrete, measured in inches. It is the distance that freshly mixed concrete subsides when a conical mold (slump cone) is lifted from the test specimen. Increasing the slump is typically done by increasing the batch water. This method also will begin to erode the strength of the concrete is the slump is raised higher that its designed level.

Sub grade – The prepared and compacted soil made to support a structure or pavement system.

Volumetric mixer – A concrete mixer that measures and produces plastic ready mix concrete by volume rather than weight. Volumetric mixers meter their concrete output as they produce the concrete, also known as continuous batching.
