Curing of cement based products such as concrete and mortar, is very important to achieve good strength and durable products. Fundamental Research on the Administrative Discretion Standard. This specification covers standard sand for use in the testing of hydraulic cements.
Small amounts of some surfactants or other contaminants will produce air voids in mortars with sand, graded sands or both. Statistical inference drawn from ANOVA testing showed that curing conditions had significant impact on strength development of the blended and unblended cement systems.
Standard sand ASTM C778 20-30
However the curing environment plays a pivotal role in the overall quality of cement based products in terms of strength development. Mark BediakoJ. The study recommends that testing of concrete and mortar samples and other research related works be performed in lime saturated water other than fresh water.

Sand shall meet the requirements with respect to grading, source of sand, c7788 absence of undesirable air entraining characteristics. Unfortunately in many parts of the world, water curing literally means curing in tap water. Both mortar specimens were cured under two different environment comprising of either water and lime saturated water.
