Usually, a type s mix has a high compressive strength of between 2,300 and 3,000 psi. Type n mortar mix, which contains one part portland cement, one part lime and six parts sand, is a medium compressive-strength mortar of at least 750 psi and can achieve 28-day strength between 1,500 and 2,400 psi.
What Is the Difference Between Type S and Type N Mortar?
Mortar is a workable paste used to bind construction materials together and fill gaps between them. It is composed of a binding agent, typically cement, and an aggregate, which is usually a combination of sand and small stones.
There are two main types of mortar: Type S and Type N. The main difference between Type S and Type N mortar is the compressive strength, with Type S mortar being the stronger of the two.
Type S mortar is a general–purpose mortar that can be used for most masonry projects. It is typically used for above–grade walls, structural masonry, and applications where a higher compressive strength is required.
Type S mortar is also suitable for use in cold weather, as it has a slower setting time than Type N mortar. Type N mortar is a versatile all–purpose mortar that can be used for most masonry projects.
It is typically used for below–grade walls, non–structural masonry, and applications where a lower compressive strength is sufficient.
Type N mortar is also suitable for use in hot weather, as it has a faster setting time than Type S mortar. Both Type S and Type N mortar are available in premixed form, or you can mix your own using
