Chemical Admixtures Portland Cement Association

Retarders keep concrete workable during placement and delay the initial set of concrete. Most retarders also function as water reducers and may entrain some air in concrete. Accelerating admixtures increase the rate of early strength development, reduce the time required for proper curing and protection, and speed up the start of finishing

Proper Method for Curing Concrete eHow

In addition, there are curing additives and admixtures, such as a product called Barrier-1, that can be mixed into the wet concrete, allowing it to cure as it dries without additional steps. However, some of these additives are cost prohibitive for the average home renovator and are more practical for contractors who do large-scale or frequent

Tips for Curing Concrete in Cold Weather

Jan 07, 2021 The process of curing concrete becomes more challenging in cold weather since, to properly set and reach maximum strength, fresh concrete must be protected from freezing for at least the first 24 hours, or until it reaches a minimum strength of 500 pounds per square inch (psi).  Concrete that freezes at an early age can lose much of its overall strength.

Role of Concrete Curing Portland Cement Association

Curing Concrete Test Specimens Curing of concrete test specimens is usually different from concrete placed during construction. American Society for Testing and Materials (ASTM) has developed two standards for making and curing concrete specimens. ASTM C192 6 is intended for laboratory samples while ASTM C31 7 is intended for field samples

The 28-Day Myth National Precast Concrete Association

Oct 28, 2013 While there are curing compounds that can be applied to concrete to keep the moisture in, we are not aware of any additives that can be applied to a concrete curing tank that will increase strength gain. Once your mix has been poured and has began curing, little else can be done besides making sure it is in a moist environment.

Curing Concrete How Long it Takes & How To Cure The

May 08, 2020 When concrete is first placed for a slab, bleed water rises as the concrete mixture settles. During this period (initial set), if the bleed water is evaporating from the surface faster than it is rising out of the concrete then you need to do some initial curing or else you are likely to end up with plastic shrinkage cracks.
