COMMAND Center to Exhibit at The Precast Show

COMMAND Center will be exhibiting at The Precast Show in Denver, Colorado at booth 2560. The show runs from February 22 to 24 in the Colorado Convention Center.

Precast teams use COMMAND Center to reliably log and monitor concrete temperature data, identify maximum and minimum temperatures to reduce the risk of DEF, analyze temperature differentials between defined locations within the element and reduce worksite hazards with rugged, minimized cable lengths.

We’ll demonstrate how to use our free, powerful software on both Windows and iOS devices, with wired and wireless data transfer options. A 10 percent discount is available for orders made at the show.

The Precast Show is the largest precast-specific trade show in North America and the one place where you can find the industry’s most important suppliers and foremost equipment experts under one roof. The Precast Show is sponsored by the National Precast Concrete Association and the Precast/Prestressed Concrete Institute, with additional collaboration from the Canadian Precast Prestressed Concrete Institute and the Cast Stone Institute. For more information, visit their website.

COMMAND Center is exhibiting at the first Canadian Concrete Expo in Toronto, Ontario in booth 459.

COMMAND Center is exhibiting at the first Canadian Concrete Expo in Toronto, Ontario. The show will be held from February 7 to 8 in the International Centre. COMMAND Center is located in booth 459.

Visit our booth to learn how COMMAND Center can help save you millions of dollars and countless hours of construction time by tracking the maturity and internal temperature of fresh, in-place concrete.

We’ll demonstrate how to use our free, powerful software on both Windows and iOS devices, with wired and wireless data transfer options. A 10 percent discount is available for orders made at the show.

COMMAND Center allows you to choose between Nurse-Saul and Arrhenius maturity functions to easily and automatically create a maturity curve, view data in the field to know if you’ve met strength requirements, share data immediately from the field, and create professional PDF reports. COMMAND Center’s state-of-the-art maturity meters come in any length you need and do not require initialization. The system is compatible with multiple readers for reading and analyzing sensor data onsite, and the comprehensive software is free.

COMMAND Center has complimentary VIP passes available. If you are interested in attending the show, please contact us for a pass.

Canadian Concrete Expo is an industry only trade show that will feature over 250 exhibiting companies on 200,000 square feet of exhibit space. CCE will create commerce, partnerships, education, face-to-face meetings with exhibitors and on-site product comparisons to an attending national audience representing Canada’s $8 billion per year concrete industry.

Florida Department of Transportation Requires Use of Maturity in Road and Bridge Projects

As outlined in the Standard Specifications for Road and Bridge Construction for opening to traffic, the Florida Department of Transportation (FDOT) requires the submittal of a strength-maturity relationship curve as determined by FM 3-C1074 during design mix verification. The state specifications also allow the contractor to use maturity in lieu of compressive strength cylinder testing every 24 hours before detensioning, and allows precast manufacturers to use maturity for determining form removal and handling strengths.

FDOT first required the use of maturity in its July 2016 specifications. Previously, maturity was allowed as an alternate to a protection set of concrete cylinders.

FDOT’s growing acceptance of the maturity method is due in part to a University of Florida study of maturity published in April 2014. The study, sponsored by FDOT, investigated the effectiveness and reliability of the maturity method to determine early-age strength of concrete in slab replacement applications.

Report: Slab replacement maturity guidelinesThe study began by examining the effectiveness of four different maturity monitoring devices; COMMAND Center, intelliRock, COMA meter, and Humboldt. After thoroughly testing the devices under various curing temperatures, researchers found COMMAND Center to be “the most effective system” because of its “accuracy, resolution, response time, and convenience of use.” The researchers then moved forward with the study using only COMMAND Center.

Researchers ran a set of lab experiments “to evaluate the possible effects of different placement and curing environments on the predicted strength of concrete from the maturity method and to determine the most appropriate procedure to be used to obtain accurate predicted strength of concrete.” They evaluated the Nurse-Saul and Arrhenius maturity functions, and concluded Arrhenius was most consistent under various curing conditions.

In the third and final section of the study, researchers conducted field studies to evaluate the effectiveness and reliability of the maturity method for predicting early-age concrete for slab replacement applications. The results indicated that “the maturity-strength prediction showed great accuracy” when the same concrete preparation time was applied to the concrete batches.

The study concluded that “the maturity method using the Arrhenius maturity function was found to be quite reliable and convenient for use in predicting the early-age compressive strength of concrete in slab replacement applications.” Because of the reliability and convenience, researchers recommended using maturity “to estimate the early-age compressive strength of concrete in slab replacement applications.”

FDOT’s January 2018 Standard Specifications for Road and Bridge Construction are currently available and will be implemented on all projects open for bidding from January 1 to June 30, 2018.

CDOT Adds Maturity Meter Requirement to Road and Bridge Construction SpecificationsThe Colorado Department of Transportation added a maturity meter requirement to its 2017 Road and Bridge Construction Specifications that took affect on October 1. The specs require for acceptance the use of the maturity method to determine concrete strength for removal of forms and falsework, loading of piers and abutments, opening of bridge decks and concrete pavement to traffic, and backfilling structures.

Several other states also include maturity in their specifications for various applications, including Texas, Alabama, Colorado, Idaho, Iowa, Kansas, Minnesota, Missouri, Montana, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Utah, Virginia, Washington, West Virginia, and Wisconsin.

What is Maturity?

Concrete maturity is a relationship between concrete temperature, time, and strength gain. It is a nondestructive test method that allows teams to evaluate concrete strength in real-time at their job site. There are many benefits to knowing real-time concrete strength gain including increased safety, expedited construction schedules, and improved construction methods. Knowing in-place concrete strength gain offers assurance that concrete has met adequate strengths for continued construction in cold weather, thus improving overall job safety. Maturity offers the potential to prove concrete has achieved adequate strength sooner than anticipated by traditional acceptance testing alone (i.e., cylinder or beam breaks).  This can lead to stressing tendons, removing formwork, and applying loads sooner, and as a result, expediting construction schedules. Measuring real-time strength gain of in-place concrete can be an indicator of mix consistency and lead to a better-quality product, thereby improving construction methods.
