Abstract
FIELD: building materials. SUBSTANCE: mixture has, wt.-%: cement 32.7-38.0; sand 47.86-52.80; superplasticizer on the basis of condensation product of naphthalenesulfoacid sodium salt with formaldehyde (C-3) 0.34-0.38; water glass 0.33-0.38; vinyl acetate 0.33-0.38, and water - the rest. Properties: compression strength of concrete after 7 days is 28.0 MPa, concrete adhesion to the steel surface is 8.2 MPa, water absorption is 5.0%. Concrete mixture is used in steel tube protective coating making. EFFECT: enhanced quality of concrete mixture proposed. 1 tbl
Description
Изобретение относится к строительным материалам, в частности к составам мелкозернистых бетонных смесей, используемых при изготовлении защитных покрытий стальных труб. The invention relates to building materials, in particular to compositions of fine-grained concrete mixtures used in the manufacture of protective coatings for steel pipes.
Цель изобретения - снижение водопоглощения, повышение прочности бетона и его адгезии к стальной поверхности. The purpose of the invention is to reduce water absorption, increase the strength of concrete and its adhesion to a steel surface.
Бетонную смесь готовят путем перемешивания портландцемента М = 400, песка и воды затворения с суперпластификатором С-3, жидким стеклом и винилацетатом в скоростном смесителе. A concrete mixture is prepared by mixing Portland cement M = 400, sand and mixing water with S-3 superplasticizer, liquid glass and vinyl acetate in a high-speed mixer.
Составы бетонных смесей (известные и предлагаемые), а также их физико-механические свойства представлены в таблице. The compositions of concrete mixtures (known and proposed), as well as their physical and mechanical properties are presented in the table.
