Treatment of material surfaces with bacterial solutions to initiate the deposition of calcium carbonate. Review
Introduction. Surface treatment plays an important role in protecting decorative stone and concrete from the effects of harmful environmental factors. To protect stone surfaces, dietary supplements in the form of carbonatogenic bacteria, the product of which is calcium carbonate, can be used.Materia...
