Learn About Masonry Cement
Especially made for mortar, masonry cement is used for building buildings! They can be used for bricks, blocks or stones but not for concrete masonry work. Masonry cement is also need for making stucco. A special blend of sand and water goes into making masonry cement for making the bind strong and durable. Not only for strength, but this cement is also considered aesthetically appealing to a lot of builders. It resists erosion and ruin and stands the test of time.
The origin of masonry cement lies in its ability to save time as compared to hydrated lime and Portland cement which called for on-site preparations. Masonry cement is a blend of Portland cement clinker, hydraulic lime filler and different kinds of additives. It is manufactured in controlled environments of factories. It also goes through a number of quality checks before being sent to the market for sale. In the U.S.A., masonry cement has to adhere to the standards of the American Society for Testing and Materials (ASTM) to be sold in the market. The function of the additives added during the manufacturing process is providing durability and also the features of acting as a water-repellent. Additives also add colors.
Masonry Cement Mixture
As mentioned above, in order to make masonry cement, Portland cement is mixed with a plasticizing element. For certain kinds of masonry cement, hydraulic cement is used instead of Portland cement. Plasticizing material mixed into any cement will give rise of masonry cement. Additives are added according to the purpose of the masonry cement since different additives add different characteristics.
Types of Masonry Cement
There are different kinds of masonry cements each of which have differing features and are used for different works.
According to American Society for Testing and Materials, main types of masonry cement are three and these are – M, S and N. Type M are used in mortars for building structures which carry a lot of weight and also paving masonry and below grade level masonry. Type S is also used for similar purposes. The type N is for general purpose mortars which can be used for the construction of walls and structures which do not carry much weight.
Manufacturing of Masonry Cement
Manufactured in a plant with strict observation, masonry cement is ensures quality. There is varying strength levels with which the cement is made and the choice of the cement will depend on the type of the structure being built. While some structures may call for a stronger quality of masonry cement, others might require a softer one. Governmental rules and guidelines determine the choice of building materials.
What Decides a Masonry Cement is good?
Good masonry cement will be scooped with ease and can be applied with a trowel. However, the working conditions of the cement also determine how good it stays. The way of mixing the mortar decides the utility of the masonry cement – if kept too dry, the bond will not take place. Also, users must keep in mind that the mortar cannot be used post 2 hours of mixing. The final responsibility of course lies with the mason.
