Concrete and mortar can be made from a mixture of masonry sand and either Portland cement or masonry cement. The addition of hydrated lime makes the concrete more plastic-like when it's wet and stronger and more durable after the concrete hardens. Masonry cement comes with lime already included.
For custom cement and mortar recipes, which result in concrete and mortar of varying strengths, Portland
and masonry cement are measured by the bag. A 94-pound bag is standard. Lime comes in 50-pound bags. Masonry sand is usually sold loose and delivered by a truck, and it's measured by the mounded shovelful.
The cement or mortar is mixed by first adding a portion of the water. The sand and cement are then poured into the water, and the mixture is stirred for several minutes. More water, cement or sand can be added if the mixture is too wet or dry.Learn more about Building Materials
