“…Different types of masonry damage accumulate over the years: destruction of the surface layers and facing, the formation of cracks and voids, local deformations leading to solidity of the masonry and weakening of the cross section. All this results in the appearance of emergency conditions (Belentsov et al, 2017;Kharitonov et al, 2019;Formisano and Marzo, 2017;Giordano et al, 2018), which can be corrected by replacing all the masonry elements, strengthening the masonry surface or restoring the stone (Forster et al, 2011;Pauletta et al, 2018;Ribilotta et al, 2019). The initial properties of the masonry material and the degree of its deterioration mean that there are a lot of possible combinations with regard to the technological methods and materials required for its restoration (Heravi et al, 2018;Myasnikova and Pervunina, 2019;Šoukal et al, 2016;Kalina et al, 2018;Gailitis et al, 2019).…”

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.

Issues of development of compositions of injectable materials on inorganic basis for underground and transport construction are considered in the paper. Inorganic binders for aqueous suspensions for strengthening of low-strength sandy and debris soils by injection into the fortified massif are proposed. The use of silica gel in combination with hydrated lime for injectable aqueous suspensions is justified. The influence of superplasticizer on the technological properties of suspensions is shown. The properties of micro-cement of different compositions are presented. Optimal ratios of components were determined. The following properties of aqueous suspensions have been studied: viscosity, sedimentation and penetrating power. The viscosity was up to 40 s, sedimentation up to 1.4%. Soil-concrete obtained by injecting the aqueous suspension based on composite binders has the compressive strength in the range of 3.3-6.2MPa.

Nowadays, it is acknowledged that the use of mineral additives based on ground slag is one of ways of resource saving and improvement of technical properties of cement composites. Mineral additives with fineness similar to the Portland cement fineness are often used to replace part of Portland cement. Two kinds of ultra-fine ground granulated blast furnace slag that differ in composition and fineness were studied in the paper. Water-reduction due to effect of super plasticizer in slag-Portland cement compositions with amount of slag up to 70% was studied. The results of reduction of binder quantity per 1 kg of chemical admixture due to significant water-reduction are obtained and analysed. Correlations depending on kind, amount and fineness of slags, as well as depending on mineralogical composition of Portland cement were stated. The ultra-fine mineral additives based on ground slag with high specific surface area can be used for significant reduction of compositional binder.
