You need to be confident that your concrete is curing correctly for the best results in your project. By storing your samples in a Darwin Chambers concrete curing box in San Francisco, CA, you can test to make sure that your concrete: Won't degrade and have fissures, technically called crazing Has the required durability Has the correct water tightness Is impervious to erosion Is resistant to shrinkage, which causes cracks Is impervious to freezing and thawing While the workers who prepare the concrete test cylinders and the San Francisco, CA lab the test is sent to will be accountable for a large percentage of the accuracy of the testing, their reports will not be accurate 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 samples were stored at. For that reason, we design and manufacture every concrete curing box to have a control resolution of 1°F. Other features include: In-field protected storage of concrete test specimens and dependable heating Comes with comfort grip no-crush handles for easy carrying No need to open to see temperature reading or set point of thermostat No overheating Digital controls Measuring resolution: 0.5°F Control setpoint: 73°F Data retention: Yes Xtreme technology uses an insulated lid and extra insulation on the interior 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 USA How to Take Concrete Curing Samples in the Field in San Francisco, CA ASTM and ACI have stringent instructions for how concrete samples are taken and stored in a concrete curing box. To ensure compliance, 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 representative of the concrete poured on-site, 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 concrete. The technician must carry out a slump test and an air test. The specimens must be kept in a concrete curing box where they will not be disturbed and are kept within 60°F and 80°F at all times. Once you have a concrete cylinder, you must keep it well-preserved in a concrete curing box until you can carry out in-field tests and send samples to a lab in San Francisco, CA to measure the concrete's compressive strength: In-Field Test: A Schmidt hammer fires a spring-loaded mass at the concrete in order to measure the value of the rebound. 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 specimen can hold up against.
