Building Mortar

masonry mortarMortar is an important building materials in our daily life. It is mainly composed of cementing materials, fine aggregates, water, mixtures and additives in a proper proportion that can be widely used to in many engineering and decorative projects, for example, it can bind stones, bricks, blocks together and fills the gaps in brick walls and the joints in large wall panels and various components walls and the joints in large wall panels and various components an an adhesive. It also can plaster brick walls, floors, and structural beams and columns. In addition to these, it is suitable to inlay natural stone, artificial stone, ceramic tiles and mosaic tiles.

The main composition of building mortar: 1. Cementing materials mainly including ordinary cement, furnace-slag cement, masonry cement and fly-ash cement with 4-5 times strength grade (that refers to the compressive strength value of 28d) are generally used to produced mortar. However, the specific cement varieties you want to use should be selected in line with the practical requirements and the strength grades should be chosen according to those of the mortar. In addition, lime, gypsum and clay can also be used as the cementing materials for mortar and they can be mixed with cement to prepare mixed mortar to save cement and improve the workability of mortar; 2. Fine aggregates that refers to the sand with the same construction requirement as the sand in concrete production. In order to ensure the quality of the mortar, the sand should be clean and the impurities content in sand should not be too high. To sum up, it should live up to the building industry standard; 3. The Clean water without harmful impurities should be adopted to mix mortar generally the same as the water requirement for concrete; 4. Adding moderate amounts of mixtures and additives can improve the workability and other construction properties of mortar or save cement, such as some inorganic fine mixtures, such as lime paste, clay paste, and fly ash. Lime should precipitate, and fly ash should be ground, for a better effect. And the types, mixing amount, and physical properties of additives should be determined by test.

surface mortarThe main classifications of building mortar in projects: Based on different purposes, it can be classified into 1. Masonry mortar--binds bricks, stone, and construction blocks together into a whole masonry; 2. Surface mortar-- is also called plaster mortar that is plastered on the surface of buildings in a thin layer to protect them, increase their durability, and also smooth their surfaces and make them clean and artistic. It can be classified into ordinary surface mortar, waterproof mortar, decorative mortar and special surface mortar according its different functions; 3. Special mortar that has certain special functions in building industry by adding unique additives that can improve its physical or chemical properties such as water-proof mortar, heat-insulated mortar, corrosion-resistant mortar, and sound-absorbing mortar; Based on different cementing materials in the formula, it can be divided into cement mortar, lime mortar, gypsum mortar, mixed mortar and polymer cement mortar. The commonly used mixed mortar includes cement lime mortar, cement clay mortar and lime clay mortar.
