Mortars for Masonry and Rendering Choice and Application
(1995) In Building Issues, Vol 7- Abstract
- Choosing the right mortar for the job, and applying it correctly, gives a strong structure requiring less maintenance. A common problem is using too much cement in the mix, which is unnecessarily expensive and has technical disadvantages. Another common problem is using too thick a layer of rendering, which increases the risk of flaking and
cracking.
A masonry wall must meet several requirements. The most important are: adequate strength, impermeability, good durability. These requirements imply certain specific standards for the: masonry unit (bricks, blocks, stones), mortar interaction between masonry units and mortar.

A masonry wall must meet several requirements. The most important are: adequate strength, impermeability, good durability. These requirements imply certain specific standards for the: masonry unit (bricks, blocks, stones), mortar interaction between masonry units and mortar.
Rendering has several functions, such as: to protect the building from external climatic and mechanical stresses,
to create an aesthetically pleasing appearance, to create a smooth surface for a final finish.
This study describes how to choose the correct mortar for different tasks, considering factors such as the characteristics of the base, how absorbent and strong it is, the weather during application, and the moisture load in the wall. Recommendations are given for the properties of the components (binder, aggregate and water), mixing, and estimating the amounts needed for typical masonry and rendering jobs. Recipes for standard mortars, giving the proportions of lime, cement and sand, are presented in a table with notes on their appropriate uses. How to use mortars is described in detail, in particular the rendering system, that might consist of three layers of different mortars, applied over a period of several days. (Less)
