Grout and Mortar

What is the difference between grout and mortar? Can mortar or concrete be used for grout? The main difference between mortar and grout is the amount of water in the mix. Grout must be made with enough water to make it pourable or pumpable but not with so much water that the grout components segregate. Grout slump generally should be between 10 1/2 to 11 inches. Mortar, on the other hand, should contain only enough water to produce a smooth, plastic, "buttery" consistency that sticks to the trowel and is easy to spread. Mortar and grout also contain different ingredients. Mortar often contains hydrated lime; grout usually contains little if any hydrated lime (ASTM C 476, Specification for Grout for Masonry, allows up to 1/10 part lime to 1 part cement). In addition, coarse grout contains larger aggregates than mortar or fine grout. Mortar should not be substituted for grout unless the substitution is allowed by the architectural specifications. Mortar often is too stiff to flow around steel into small cavities or cores without leaving voids. These voids not only reduce strength but also can lead to water leakage problems. Mortar often is used to slush collar joints instead of filling collar joints with grout. This practice is convenient to masons but has disadvantages.
