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...

8 cze 2023 · This study presents a comparative analysis of laboratory-produced masonry mortars, compacted using four different methods, namely manual tamping and tapping and mechanical jolting and vibration, all of which are specified in masonry and cement-specific standards.
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.
chemical analysis on the materials in historic mortars. Acid dissolution/separation of binder from aggregate is the simplest method, and allows the determination of the chemical composition of the acid-soluble binder and, after separation, information on the mortar’s aggregate.
