Abstract

Изобретение относится к составу комплексной суперпластифицирующей добавки для бетонов и строительных растворов и может найти применение при производстве бетонных и железобетонных изделий и конструкций. Технический результат - повышение сохраняемости бетонной и растворной смеси с комплексной добавкой. Добавка для бетонов и строительных растворов, включающая суперпластификатор нафталинформальдегидного типа и натрийкарбоксиметилцеллюлозу, содержит в качестве суперпластификатора нафталинформальдегидного типа С-3 или Полипласт СП-1 при следующем соотношении компонентов, мас.%: указанный суперпластификатор 95-99, натрийкарбоксиметилцеллюлоза 0,5-5.The invention relates to the composition of the complex superplasticizer additives for concrete and mortars and may find application in the manufacture of concrete and reinforced concrete products and structures. The technical result is to increase the persistence of concrete and mortar mix with a complex additive. Additive for concrete and mortar, including naphthalene formaldehyde-type superplasticizer and sodium carboxymethylcellulose, contains C-3 naphthalene formaldehyde-type superplasticizer or Polyplast SP-1 as a superplasticizer in the following ratio of components, wt.%:
