The potential for increased efflorescence was also investigated.
While Portland cement continues to be commonly used in new constructions of brick and concrete, it is not recommended in the repair and restoration of brick and stone-built structures originally built using lime mortar. Lime mortar is more porous than cement mortars, and it wicks any dampness in the wall to the surface where it evaporates.
Portland cement is about 30% clay-based, while lime is usually about 5% clay. However, there are three basic strengths of lime mortar, depending on the amount of clay present. The closer the clay percentage gets to 30%, the closer it is to a Portland cement, since the strength will be the same.
Overview Information Lime is a citrus fruit. The juice, fruit, peel, and oil are used to make medicine. Oil pressed from the crushed fruit is known as "distilled lime oil."
Addition of lime in curing tanks. Q. Why is it important to add lime to water in curing tanks? A. The reason for adding lime to the water is to prevent calcium carbonate from leaching out of the concrete as the cylinders are cured. The requirements can be found in the latest edition of ASTM C511. References: ASTM C511. Topics in Concrete: Testing
