How the concrete cures and the accuracy of the tests is vital to the success of your project. By keeping your samples in a Darwin Chambers concrete curing box in Charlotte, NC, you can test to demonstrate that your concrete: Won't develop cracks, also referred to as crazing Has the required durability Has the correct water tightness Is not susceptible to wearing down Is impervious to shrinkage, which causes cracks Is impervious to freezing and thawing In order to properly verify the above and have accurate tests, you You need to know the precisely the conditions the samples were stored at. For that reason, we design and manufacture every concrete curing box to have a control resolution of 1°F. Other aspects include: On job site protected storage of concrete test specimens and reliable heating Comes with comfort grip no-crush handles for easy carrying Exterior controls and readings so the box can remain closed No overheating Digital controls 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 Low CO2 insulation for reduced carbon emissions from foam manufacturing Produced in the United States How to Take Concrete Curing Samples in the Field in Charlotte, NC ASTM and ACI have strict standards for how concrete samples are taken and stored in a concrete curing box. To ensure you are complying with regulations, you must take the following steps: The procedure must be carried out 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 note a precise reading of the temperature of the ambient air and the specimen. You must conduct a slump test and an air test. The samples must be kept in a concrete curing box where they will not be agitated and are kept within 60°F and 80°F at all times. After the slump and air tests, you must perform in-field tests and send samples to a lab in Charlotte, NC to take a reading of the concrete's compressive strength: In-Field 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: A compressive strength lab test will apply force to each end of the cylinder until it breaks to see how much pressure the concrete can withstand.
