FIELD: chemistry.
SUBSTANCE: invention relates to production of building materials, particularly compositions and methods of impregnating fibre-cement articles. The water-repellent composition for impregnating fibre-cement articles contains, wt %: polyphenylethoxy siloxane 25-75, kerosene 75-25. In the method of impregnating fibre-cement articles with a water-repellent composition, involving coating and drying, the water-repellent composition used is said composition; coating is carried out on open air for 5.5-7 hours or by vacuum treatment for 4-5 minutes, and drying is carried out at temperature of 50-60°C until achieving constant mass.
EFFECT: low water-absorption of fibre-cement slabs and high strength thereof in a water-saturated state.
