Abstract
Since ancient times, limestone has been known as an inexpensive and reliable building material. However, there are problems associated with the restoration of historical buildings made of this natural stone. In this paper, the object of study is Crimean nummulitic limestone of natural origin and nummulitic limestone treated with stone-strengthening composition Oxal NK100. The purpose of this scientific work is practical confirmation of the improvement of the physical and mechanical parameters of nummulitic limestone, such as a decrease in porosity and an increase in strength, after its treatment with Oxal NK100. A review of literature on the problem of durability and the study of the physical and mechanical properties of limestone is presented. The porosity and strength of both types of limestone were determined experimentally, and the obtained data were analyzed. It was revealed that the composition Oxal NK100 increases the strength characteristics of the stone and slightly affects its porosity. Conclusions about the effectiveness of the use of stone-strengthening composition are made.
