Hydrated Lime Type S 50-Pound

Western Miracle Lime is Type S (Special) Dolomitic Hydrated Lime, also known as calcium magnesium hydroxide. The fine, white powder is produced by calcining high purity dolomitic limestone, followed by pressure hydrating and milling the lime. BASIC USE Western Miracle Type S Lime, when mixed with portland cement, sand, and water, is the key ingredient in the mixing of highly plastic workable mortar needed for durable, water resistant masonry. The capacity of a masonry mortar to retain satisfactory workability under the influence of masonry unit suction and evaporation rate depends on the water retentivity and setting characteristics of the mortar. Lime based mortars exceed minimum requirements for water retention and thus contribute to greater workability and plasticity. This enables the mortar to be spread easily into the cracks and crevices of the masonry units. Because of the workability of lime based mortars, there is better bond between mortar and masonry unit. Good bond is important for resistance to water penetration and resisting the flexing forces of wind and ground movement. Mortars made with portland cement and Western Miracle Lime exhibit superior bond values when tested according to ASTM 1072.
