Why You Need Concrete Curing Testing in Minneapolis, MN

Based on a report from ACI Committee 308, curing is "the process by which hydraulic-cement concrete matures and develops hardened properties over time." How the concrete cures and the accuracy of the tests will go a long way in the success of your project. By keeping your samples in a Darwin Chambers concrete curing box in Minneapolis, MN, you can test to verify that your concrete:

  • Won't develop cracks, technically referred to as crazing
  • Has the correct strength
  • Has the needed water tightness
  • Is not susceptible to abrasion
  • Is not susceptible to shrinkage, which causes cracks
  • Is resistant to freezing and thawing

While the experts who prepare the concrete test cylinders and the Minneapolis, MN lab the test is sent to will be accountable for a large portion of the accuracy of the testing, their readings will not have any value if the reliability of the sample is put at risk because the concrete was not stored correctly. You need to know the precisely the temperature and humidity the specimens were stored at. That's why we design and manufacture every concrete curing box to have a control resolution of 1°F. Other features are:

  • In-field protected storage of concrete test specimens and dependable heating
  • Comes with comfort grip no-crush handles for easy carrying
  • Exterior controls and readings so the box can remain closed
  • The plate is thermally protected from overheating
  • Digital temperature controller
  • Reading resolution: 0.5°F
  • Control setpoint: 73°F
  • Data retention: Yes
  • Xtreme technology uses an insulated lid and extra insulation in the walls
  • EZ-Clean top wipes clean and the lead-resistant channel drain makes it easy to empty any excess water without tilting the cooler
  • Eco-friendly manufacturing through reduced carbon emissions
  • Made in the United States

Correct Procedures for Concrete Curing Samples in the Field in Minneapolis, MN

ASTM and ACI have stringent standards for how concrete samples are taken and stored in a concrete curing box. To ensure you are adhering to regulations, you must take the following steps:

  • The concrete must be made, cured, and tested by an ACI-Certified Grade 1 Concrete Field Technician.
  • The concrete cylinder must be a "representative sample," made up of at least two samples.
  • The technician must take an accurate reading of the temperature of the ambient air and the specimen.
  • The worker must conduct a slump test and an air test.
  • The cylinders must be kept in a concrete curing box where they will not be perturbed and cannot exceed 80°F or go below 60°F.

After the slump and air tests, you must conduct both in-field and laboratory tests in Minneapolis, MN to test the concrete's compressive strength:

  • In-Field Test: A small device, known as a Schmidt hammer, measures the rebound of a spring-loaded mass that is shot against the surface of the concrete.
  • Laboratory Test: In a lab, the concrete will be placed in a machine that places increasing amounts of pressure on each end of the cylinder until it cracks or breaks.
