How the concrete cures and the accuracy of the tests is vital to the success of your project. By using a Darwin Chambers concrete curing box in St. Louis, MO, you can test to establish that your concrete: Won't have cracks, also known as crazing Has the correct durability Has the appropriate water tightness Is resistant to abrasion Is impervious to shrinkage, which causes cracks Is resistant to freezing and thawing While the experts who prepare the concrete test cylinders and the St. Louis, MO lab the test is sent to will be responsible for a considerable 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 of a poor concrete curing box. You need to know the exact temperature and humidity under which the samples were kept. That's why we design and manufacture every concrete curing box to have a control resolution of 1°F. Other specifications are: In-field protected storage of concrete test specimens and reliable heating Comes with comfort grip no-crush handles for easy carrying No need to open to read or set temperature No overheating Digital temperature controller Reading resolution: 0.5°F Control setpoint: 73°F Ability to preserve data Xtreme technology uses an insulated lid and extra insulation on the siding EZ-Clean top wipes clean and the lead-resistant channel drain makes it easy to empty any excess water without tilting the cooler Low CO2 insulation for reduced carbon emissions from foam manufacturing Made in the USA Correct Procedures for Concrete Curing Samples in the Field in St. Louis, MO ASTM and ACI have stringent standards for how to make samples and what humidity and temperature to store them at. To ensure compliance, you must take the following steps: The procedure must be conducted by an ACI-Certified Grade 1 Concrete Field Technician. The concrete cylinder must be a "representative sample," made up of two different samples from the middle of the concrete load. The technician must take a precise reading of the temperature of the ambient air and the sample. The technician must perform a slump test and an air test. The specimens must be stored in a concrete curing box where they will not be perturbed and cannot exceed 80°F or go below 60°F. In addition to the slump and air tests, you must perform both on-site and laboratory tests in St. Louis, MO to test the concrete's compressive strength: On-site Test: A small device, known as a Schmidt hammer, fires a spring-loaded mass with a defined energy against the surface and reads how elastic or strong the concrete is. Laboratory Test: In a lab, the concrete will be placed in a machine that places increasing amounts of pressure on each end of the concrete until it cracks or breaks.
