“…In [13][14][15][16][17] it was proposed to use calcium hydrosilicates synthesized using diatomite as an active additive. X-ray diffraction analysis revealed that the mineralogical composition of a additives based on synthesized calcium hydrosilicates synthesized using diatomite is represented by calcium hydrosilicates of the tobermorite group, C-S-H (II) solution, quartz, kaolinite and hydrogalites (Fig.…”

Information is given on the possibility of using additives based on calcium hydrosilicates synthesized using diatomite and amorphous aluminosilicates as modifying dry mortar in the formulation. The data of the analysis of mineralogical composition of the investigated additives are given, the influence of additives on the change in the plastic strength of the lime test and the content of free lime is revealed. The kinetics of the change in the strength of lime samples was studied, which confirmed that the investigational additives possess a structuring effect and can be used as modifying agents.

“…In [ 22 , 23 , 24 ], it was proposed to use synthesized calcium silicate hydrates (CSH) to increase the durability of lime coatings. A lime composition has been developed for finishing and restoring the walls of buildings in the form of a dry mixture containing a filler based on CSH and allowing to obtain mortar mixtures with a water-retaining capacity of 98–99%, drying time of 15–20 min, pot life 1–1.5 h. Coatings based on the proposed dry mortar (DM) are characterized by a vapor permeability coefficient of 0.05 mg/m·h·Pa, adhesion strength of 0.6–0.9 MPa, compressive strength of 3–4 MPa.…”

Lime materials are in great demand for the restoration of the walls of historical buildings. However, lime coatings have insufficient resistance during operation. The purpose of this work was the modification of lime mortars with silicic acid sol in order to obtain more durable crystalline materials for construction purposes. A technology has been developed for obtaining a silica-containing additive, which consists in passing a liquid glass solution with a density of 1.053 kg/m3 through a cationic column and obtaining a silicic acid sol with a pH of 3–4 and a charge of (−) 0.053 V. The regeneration time and the amount of sol have been determined. Regularities of change in the radius of particles of silicic acid sol depending on age are determined. It is established that at an early age (up to 5 days), the radius of sol particles can be determined in accordance with the Rayleigh equation, and at a later age, in accordance with the Heller equation. The results of the calculation show that at the age of 1–5 days, the radius of the sol particles is 17.1–17.9 nm, and then the particles become coarser and the particle radius is 131.2–143 nm at the age of 19 days. The work of adhesion of silicic acid sol to lime and the heat of wetting are estimated. It is shown that the work of adhesion of water to lime is 28.9 erg/cm2, and that of the sol is 32.8 erg/cm2. The amount of heat Q released when lime is wetted with SiO2 sol is 15.0 kJ/kg, and when lime is wetted with water, it is 10.6 kJ/kg.
