What is a brick mortar?
Mass mortar is a building material that is used as a binding agent for masonry work. It is used to connect bricks, concrete blocks or stones and keep them firmly in place over time. The meat mortar begins like a strong paste, then over time dries or heals to form a thick material that is almost as hard and strong as the stone itself.
There are three basic formulas for creating brick mortar. The most widespread is Portland cement mixture, which includes Portland cement, water and sand. Newer versions are used by polymers such as latex or resin, to complement the natural binding substances in the cement. This material, known as polymer cement mortar, is more resistant and resistant to damage than traditional Portland cement mixtures. Finally, some installer still rely on classic lime mortar made of limestone, brick dust and water.
During construction, the masonry of mortar on the upper and sides of each stone. Excess material is removedIvepovrch material. Another mortar can be added to balance the appearance of the structure, then the tools are used to create a smooth or rounded joint line inside the mortar before drying.
Mass mortar is also used to repair or restore existing structures. The old mortar is shouted and replaced by fresh material in a process known as "tuck" or "direction". In buildings, which were originally designed using lime mortar, it is important to stick to the mixture based on lime to avoid problems with moisture in areas where old and new mortar mixtures interact.
The American Society for Testing and Materials (ASTM) is an international organization that creates the most used standards for construction products, including mortar. The ASTM C270 “Standard Mortex specifications for unit masonry” is used throughout the world to standardize and categorize various Mortar types. By thatThe publication can be divided into four categories, each of which is accidentally named using a different letter found in the word "mason". Each type is characterized by its strength and durability, which is based on components and at the moisture level contained in each mixture.
type N is the most commonly used variety and is designed for all normal above -ground applications. It is the most affordable of all four types and has an average level of strength and hardness. Type S is used in the applications under the class, such as foundations and basements, while type M is designed for extremely heavy loads. The type o mortar is mainly used for the direction of existing walls, although it can also be used in applications that are subject to very low temperatures due to its low moisture content.
