INTRODUCTION. The formulation of existing hardened mortars is often needed for conservation work. Laboratory analysis can provide a detailed description of mortar composition and aggregate gradation to provide appropriate proportions for repointing and rebuilding mortar.
1 cze 2013 · The mixing of solid materials with water is one of the most important steps in the preparation of mortars. The mixing procedure interferes with both fresh and hardened properties. The ABNT NBR...

In order to design a restoration mortar with properties and composition similar to the original mortar, it is important to analyze the historic mortar in several ways. A combination of analyses give information about the mixing ratio between binder and aggregates, chemical composition of the mortar, additives, tool marks, application technique etc.
In addition to the mineralogical characterisation of components of binder and aggregate in historic mortars, it is sometimes necessary to perform a chemical analysis on the materials in historic mortars.
We propose the method of design of mortars on the basis of dry mixes that consists of six stages: Composing the task for design (design assignment) of the mortar on the basis of a dry mix with substantiation of the main specifications: processing, physico-mechanical, and engineering-performance ones.
12 sty 2022 · Several research studies are available in the international literature on the study of restoration mortars, and particularly, the relationship between the raw materials selected, the mortar mix design, and the developed mortar characteristics.
