Description

The invention relates to the construction materials industry.

Known concrete mixture, including, by weight. h: Portland cement 1.0; fine aggregate (ash and slag) 3.6-9.7; shredded plastic (polyethylene foam) 0.024-0.009; water 0.6-1.1 [1].

The objective of the invention is to increase the strength of concrete.

The technical result is achieved in that the concrete mixture, including Portland cement, fine aggregate, shredded plastic, water, contains chopped rings and / or half rings with a thickness of 3 ± 1 mm, polypropylene pipes with a diameter of 20 mm or 32 mm, and fine aggregate, as chopped plastic - quartz sand in the following ratio of components, wt. h: Portland cement 21.45; silica sand 64.23-66.63; polypropylene pipes cut with rings and / or half rings with a thickness of 3 ± 1 mm with a diameter of 20 mm or 32 mm 0.8-3.2; water 11.105.

The compositions of the concrete mixture are shown in the table.

Spent, defective polypropylene pipes with a diameter of 20 mm or 32 mm (for water supply) or their scraps are cut into rings and / or half rings. The thickness of the rings or half rings is 3 ± 1 mm.

To prepare the concrete mixture, raw materials are prepared and dosed. Portland cement (M500), quartz sand, cut into rings and / or half rings with a thickness of 3 ± 1 mm, the polypropylene pipes are mixed, water is added and mixed again. The resulting concrete mixture is placed in metal (pre-lubricated with machine oil) molds and left to solidify. Then the products are removed from the molds and transported to the finished goods warehouse.
