Who Uses Concrete Maturity?

Builders, contractors, subcontractors, suppliers, and testing firms who need to quickly evaluate when in-place concrete reaches a desired strength will use the maturity method.

Owners, engineers, and architects often specify maturity as an option or requirement in project specifications to increase revenue, safety, and competitiveness.

Builders

Builders (general contractors, construction managers, etc.) use maturity to:

Meet Specifications

Many projects allow the use of maturity as an option for evaluating strength in the field, so builders should understand the benefits of the maturity method and be prepared to implement it.

Increase the potential for monetary bonuses

Maturity monitoring saves time and improves the quality of the final product—this can translate to overall project cost savings.

Increase safety

Builders who use maturity monitoring on their projects are implementing a method that can help prevent structural failure.


With maturity monitoring, builders can estimate their concrete’s in-place strength in real time. Builders use maturity monitoring to prove their concrete is achieving strength quickly in the field, allowing them to expedite the project’s construction schedule. Speeding up the construction schedule can often translate into bonuses. Bonuses can offset the cost of the project and ultimately result in savings for the contractor.

Maturity monitoring can expedite schedules by allowing:

  • Earlier post-tensioning procedures
  • Earlier removal of formwork
  • Earlier application of heavy loads (e.g., traffic or multi-story construction)

When builders use maturity to evaluate the in-place strength of concrete, they require less cylinder specimens for overall quality control during construction. This can result in even more project cost savings.

Builders can use maturity to improve construction methods at joints and during cold weather placements. Improved construction methods will result in better quality, which ultimately minimizes the potential need for repair or reconstruction. Minimized repair and reconstruction before a project is finished or while it is still under warranty can result in overall project cost savings.


Owner agencies, architects, or engineers may require a builder to use maturity in order to ensure that their in-place concrete is reaching required strength. Builders who use the maturity method don’t have to rely solely on concrete samples tested in a laboratory environment—instead, they can track the progress of their actual concrete placed in the field.

When an owner, architect, or engineer decides to allow the option to implement maturity on a job, they will state the requirements in the job specifications. When maturity is not required or stated as an option, builders who are familiar with the benefits of maturity monitoring may ask the project owner or engineer to approve the maturity method so they can save time and money on the project.

Subcontractors and Suppliers

Concrete subcontractors and suppliers use maturity to:

Meet specifications

If specifications require maturity, subcontractors or suppliers may need to implement it.

Rise above the competition

Concrete subcontractors and suppliers looking to gain an edge in the industry offer mixes with accompanying maturity curves. This helps the subcontractor or supplier provide a mix that specifically meets the customer’s needs for a particular project. Customers already familiar with maturity will appreciate the service; customers who are not familiar with it are offered the chance to learn more about the benefits of maturity monitoring. Monitoring concrete maturity can give concrete subcontractors or suppliers an advantage over those who do not.

Testing Firms

Testing firms specify or recommend maturity monitoring to:

Meet specifications

Many projects now require maturity monitoring. Testing firms can offer their services for this early on in the project planning to capture the work instead of the contractor implementing maturity on their own.

Rise above the competition

Firms that are looking for an edge in the industry may discuss maturity monitoring with their clients as a value add service. Also, with more and more projects specifying or allowing maturity, firms with experience in maturity monitoring will have a distinct advantage over their competitors.

Increase likelihood of re-hire by clients

Maturity monitoring may expedite construction schedules, leading to increased profits for the owner and builder. If a firm recommends maturity and uses it to increase profits for an owner or builder, that owner or builder may be more likely to hire that firm again.


When a project’s specifications do not mention maturity monitoring, many firms might not think to recommend maturity to a contractor or owner—especially if they are unfamiliar with maturity or are reluctant to adjust their standard operations.

Firms that are familiar with the advantages of maturity monitoring can provide superior service by recommending maturity to their clients, saving them time and money and improving quality control and assurance.

Owners and Owner Agencies

Owners specify maturity monitoring on their projects to:

Increase safety

When concrete strength is verified by maturity monitoring, owners can be more confident that their concrete’s in-place strength is adequate, which will reduce the potential for structural failure that may lead to damage, injury, or death.

Increase profits

Maturity monitoring allows contractors to know the moment their in-place concrete has reached sufficient strength so they can move on quickly to the next phase of construction. Owners often use this advantage of maturity monitoring to expedite construction schedules—which can amount to millions of dollars saved on a project.

Engineers and Architects

Engineers and architects specify maturity on their projects to:

Increase revenue

Maturity monitoring may expedite construction schedules, leading to increased profits for the owner and builder—those savings may make the owner or contractor more likely to hire that engineering or testing firm again if they are the ones who are proactive about the implementation.

Rise above the competition

Firms that are looking for an edge in the industry may discuss maturity monitoring with their clients as a value add service. Also, with more and more projects specifying or allowing maturity, firms with experience in maturity monitoring will have a distinct advantage over their competitors.

Increase safety

Maturity monitoring can verify that in-place concrete is reaching adequate strength and help prevent accidents or damage caused by putting loads on concrete prematurely.

When using the maturity method, construction teams can estimate real-time strength gain of in-place concrete on the job site. There’s no need to waste valuable construction time waiting for the strength of standard test specimens to catch up to the in-place concrete.

Without maturity monitoring, in-place concrete strength is estimated by performing compressive cylinder tests in a laboratory. Relying solely on lab tests requires several specimens and can waste valuable time if a project’s in-place concrete reaches sufficient strength before standard test intervals. In the construction business, time is money.

To save time and money on a project, the construction team monitors maturity to quickly determine when concrete has reached its required strength.

Key Maturity Benefits

  • Concrete strength can be evaluated in real-time.
  • Less time is spent waiting for test specimens to catch up to concrete strength.
  • The number of test specimens required for QC and potentially QA will decrease.
  • Tendons may be stressed, forms and shores may be stripped and removed, and loads may be applied sooner than otherwise anticipated.
  • Expedited schedules may result in bonuses.
