Benefits of Concrete Curing Testing in St. Louis, MO

According to a a definition offered by ACI Committee 308, curing refers to "the process by which hydraulic-cement concrete matures and develops hardened properties over time." The success of your project will partially be dependent on how the concrete cures and your ability to accurately test it. By storing your samples in a Darwin Chambers concrete curing box in St. Louis, MO, you can test to verify that your concrete:

  • Won't develop fissures, technically referred to as crazing
  • Has the required durability
  • Has the required water tightness
  • Is not susceptible to wearing down
  • Has better volume stability
  • Is not susceptible to freezing and thawing

In order to properly verify the above and have accurate readings, you You need to know the precisely the conditions the specimens were stored at. For that reason, we design and manufacture every concrete curing box to have a control resolution of 1°F. Other aspects are:

  • 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 you do not have to open the box
  • The plate is thermally protected from 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
  • Manufactured 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 produce samples and what conditions to store them under. 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 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 concrete.
  • The technician must run a slump test and an air test.
  • The cylinders must be placed in a concrete curing box where they will not be agitated and cannot exceed 80°F or go below 60°F.

Once you have a concrete sample, you must keep it well-preserved in a concrete curing box until you can perform both on-site and laboratory tests in St. Louis, MO to take a reading of the concrete's compressive strength:

  • On-site Test: A Schmidt hammer fires a spring-loaded mass at the concrete in order to measure the value of the rebound.
  • Laboratory Test: In a lab, the concrete will be placed in a device that places increasing amounts of pressure on each end of the sample until it cracks or breaks.
