Cement mortar is much stronger than lime mortar. 4)special mortar, 1) according to binding material depends on several factor like working condition , hardening , temperature and moisture condition following type are:-, A) cement mortar Mortars use as the plaster or impermeable covering for walls and roofs. B) Lime mortar:- in this type of mortar lime is used as binding material lime mortar has high plasticity and it can be easily place and it posses good binding and cohesiveness with the surface but it hardens very slowly ,lime mortar have two types fat lime and hydrated lime. Plastering also provides a satisfactory base for painting, distempering, white washing, or colour washing. Strength, durability, and many other factors depend on the relative amounts and properties of the individual components. This article concerns the physical and chemical properties of cement, as well as the methods to test cement properties. after mixing mortar is stone like material as a result of hardening .binding mortar does not contain coarse aggregate it has only fine aggregate that is sand. in this type of mortar gypsum is used for binding material. Sand, on the other hand, eliminates or reduces cracks produced by the contraction of cement while it sets. Different methods are used to plaster concrete surfaces such as dense concrete, low-weight concrete and mixed concrete surfaces. Following types are commonly used. Above 50 MPa, the term High Performance Concrete is used (50 MPa corresponds to a force of 50 tonnes acting on a square with sides of ten centimetres). Cracks should not be developed in the joint formed by mortar. Copyright © 2020 CivilSir Therefore, the properties of a good mortar must be investigated. Required fields are marked *.

The production of Portland cement (OPC) is increasing annually worldwide by 9% and about 4 billion tons is produced. Resistance to aggressive chemicals in the atmosphere, such as acid rain, is also of concern. The plaster is typically manufactured as a dry powder and then worked to form a stiff paste by mixing in waterbefore application. 3. Cement, a popular binding material, is a very important civil engineering material. Higher workability concretes are easier to place and handle but obtaining higher workability by increasing water content decreases strength and durability. Though the terms are often used synonymously, cement, concrete, and mortar are actually three distinctly different materials: 1) fat lime :- it has agent material like calcium oxide and it hardening depend on loss of water and absorption of carbon dioxide from environment. 3.2 Freezing and thawing resistance.
