Abstract

FIELD: manufacture of building materials. SUBSTANCE: concrete mixture has : cement 35-50 wt %; sand 35-55 wt %; superplastifier (sodium salt of the condensation product of naphtaline with formaldehyde); water to the balance. The mixture is prepared by grinding cement with superplastifier until specific surface of 6400-7000 sq.cm/g is obtained followed by mixing components under water to cement ratio 0.25-0.30. EFFECT: increased plasticity of mixture and strength of hardened pieces. 2 cl, 2 tbl

Использование: в промышленности строительных материалов, в частности при получении пластичных цементно-песчаных бетонных смесей для изготовления облицовочных изделий. Сущность изобретения: бетонная смесь содержит, мас.%: цемент 35,0 - 50,0; песок 35,0 - 55,0; суперпластификатор-натриевую соль продукта конденсации нафталинсульфокислоты с формальдегидом С-3 0,71 - 0,86; воду остальное. Способ получения этой бетонной смеси заключается в помоле цемента с суперпластификатором - натриевой солью продукта конденсации нафталинсульфокислоты с формальдегидом С-3 до удельной поверхности 6400 - 7000 см2/г и смешении компонентов смеси при водоцементном отношении 0,25 - 0,30. Достигаемым техническим результатом является повышение пластичности смеси и активности, особенно в ранние сроки твердения, что обеспечит высокую прочность изготавливаемых из этой смеси изделий. Кроме того, достигается повышение качества поверхности изготавливаемых изделий.Usage: in the building materials industry, in particular upon receipt of plastic cement-sand concrete mixes for the manufacture of facing products. The inventive concrete mixture contains, wt.%: Cement 35,0 - 50,0; sand 35.0 - 55.0; superplasticizer-sodium salt of the condensation product of naphthalenesulfonic acid with formaldehyde C-3 0.71 - 0.86; water the rest. The method of obtaining this concrete mixture consists in grinding cement with a superplasticizer - the sodium salt of the condensation product of naphthalene sulfonic acid with C-3 formaldehyde to a specific surface of 6400 - 7000 cm 2 / g and mixing the mixture components at a water-cement ratio of 0.25 - 0.30. Achievable technical result is to increase the ductility of the mixture and activity, especially in the early stages of hardening, which will provide high strength products made from this mixture. In addition, an improvement in the surface quality of manufactured products is achieved.
