Concrete Cylinder Curing
The hydration and hardening that takes place during the first several days is extremely important. If the concrete is dried too rapidly from evaporation or shrinkage, the result could be insufficient strength and greater shrinkage cracking. Minimized cracking can be achieved by reducing stress prior to curing. Proper curing with the right equipment will result in increased strength and lower permeability, even if the surface dries prematurely.
Tight control over the temperature and humidity is critical during the curing period. Accelerated curing techniques are sometimes used for higher strength results, involving heating so that the hydration process occurs more quickly.
ASTM C31/C31M designates the standard practice for making and curing concrete test specimens in the field. Specifically this covers proper procedures for making cylinder and beam specimens from concrete samples for a construction project, as well as the transportation, storage and curing of samples.
Humboldt’s concrete cylinder curing products were designed and developed for accurate and repeatable results and in compliance with appropriate ASTM and AASHTO standards.
