Optimization of repair mortar used in masonry restoration

Abstract

Deterioration of ancient masonry is a contemporary problem. The initial properties of the masonry material that determine its durability, deterioration and degree of preservation have led to the appearance of different approaches towards choosing the technology for restoring masonry. The success of any restoration is largely determined by its compatibility with the original materials used, which requires, as a rule, a complex and long process of selecting their composition. One of the main technological approaches in the science of restoration materials is to search for the optimal composition of the material within a given time limit. This paper presents an approach which uses a large number of variables within strict boundary conditions. The solution to this problem can be found in the field of mathematical modelling using experiment planning methods. The paper presents a method developed for mortar optimization which makes it possible to obtain the desired result within a relatively short period of time.

Research of the Possibility of Creation of a Multipurpose Complex Additive for Dry Mixtures

“…Studying the literary sources [4][5][6][7][8][9][10][11][12], it can be summarized that it is often possible to increase the solidification rate by including alkali and alkaline earth metals in the mixtures. The final recipe is selected in each case separately [13][14][15][16][17][18][19][20].…”
