FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil and gas production industry, namely to expanding oil wells, and can be used for cementing inter-column space in oil and gas wells, and also to the construction sphere for fastening elements of building structures, anchor bolts, decor elements. Composition of the plugging action contains Portland cement and quartz sand with a grain size of not more than 2.5 mm. Quartz sand with chalcedony is pretreated with a stream of accelerated electrons with an absorbed dose of 600 kGy. Composition has the following component ratio, mass%: Portland cement 36–40, quartz sand 60–64.
EFFECT: technical result of the invention is an increase in linear expansion, tensile strength in bending.
