"Nonetheless, the application of a curing compound
in construction is needed to facilitate the hydration process of the concrete as well as mitigate the moisture loss-induced distress."
The concern with the faster curing compound
is the scorch time.
The TC12-28, meanwhile, will be used to apply "a tined finish to the concrete or a full coverage of liquid curing compound
, ensuring that the freshly paved concrete cures properly in the Middle East temperatures".
. Rock Cure O2P water based concrete curing compound
complying with ASTM C-309 (ASTM, 1999b), Type 2, Class A was used in this study.
Pros often skip the plastic and spray on a waxy liquid "curing compound
" to slow down evaporation.
The Spray Thick[TM] Curing Compound
Sprayer is designed to spray up to 35 percent solids.
The surface must be kept wet by either constant "misting" or applying a curing compound
designed to form a membrane on the surface.
B- A pigmented curing compound
is sprayed on damp concrete.
The 2016 Missouri Concrete Conference, May 3-4 on the Rolla campus, will feature presentations covering steel or macro synthetic fibers in concrete; impact of air pollution control on fly ash; proper curing techniques and materials; soil stabilization and full-depth reclamation; new American Concrete Institute pavement construction guide; lithium silicate curing compound
; floor slabs and toppings; practical applications of resistivity testing; the Super Air Meter; city and county pavement management programs; and, Missouri Department of Transportation bridge girder specifications.
