The main function of the curing compound （curing agent） is to coat the surface of the concrete to form a dense film to isolate the surface of the concrete from the air, prevent the evaporation of moisture, and make the concrete use its own moisture to maximize the hydration of the admixture.
Concrete curing is just not placement and finishing, it requires care and attention so that concrete serves its purpose Concrete under water curing and curing under freezing conditions means taking care of factors like moisture content, the type of cement used, and the use of additives to speed up or slow down the evaporation rate from the concrete surface Even in extremely hot conditions .

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.
Curing plays an important role on strength development and durability of concrete. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time.
Concrete admixtures are natural or manufactured chemicals or additives added during concrete mixing to enhance specific properties of the fresh or hardened concrete, such as workability, durability, or early and final strength. For over.
CureFAST Cement Additive uses carbon nanotubes to fill in the micropores at the nanoscopic level between cement particles, sand and gravel. When concrete cures, instead of leaving voids which would cause defects and damage, the nanotubes create carbon bonds alongside the dry particles strengthening the entire admixture.
