Description

Изобретение относится к промышленности строительных материалов, в частности к производству мелкозернистых бетонов.The invention relates to the construction materials industry, in particular to the production of fine concrete.

Известна сырьевая смесь для изготовления мелкозернистого бетона, содержащая портландцемент, кварцевый песок, водоудерживающую добавку [1].Known raw mix for the manufacture of fine concrete containing Portland cement, quartz sand, a water-retaining additive [1].

Задача изобретения состоит в повышении прочности мелкозернистого бетона.The objective of the invention is to increase the strength of fine-grained concrete.

Технический результат достигается тем, что сырьевая смесь для изготовления мелкозернистого бетона, содержащая портландцемент, кварцевый песок, водоудерживающую добавку, воду, в качестве водоудерживающей добавки содержит полиакрилат натрия при следующем соотношении компонентов, мас. ч.: портландцемент 24-26; кварцевый песок 74-76; полиакрилат натрия 0,01-0,1; вода 11-15.The technical result is achieved in that the raw mixture for the manufacture of fine concrete containing Portland cement, quartz sand, a water-retaining additive, water, as a water-holding additive contains sodium polyacrylate in the following ratio of components, wt. h: Portland cement 24-26; silica sand 74-76; sodium polyacrylate 0.01-0.1; water 11-15.

Составы сырьевой смеси приведены в таблице.The composition of the raw mix is shown in the table.

Компоненты дозируют в требуемых количествах. Полиакрилат натрия замачивают в воде, выдерживают до набухания и измельчают до образования гелевидной массы. Все компоненты смешивают и подготавливают сырьевую смесь, которой заполняют металлические формы. Смесь уплотняют и выдерживают в формах в течение суток, затем изделия извлекают из форм и направляют на склад готовой продукции.The components are dosed in the required amounts. Sodium polyacrylate is soaked in water, kept until swelling and crushed to form a gel-like mass. All components are mixed and a raw material mixture is prepared, with which metal forms are filled. The mixture is compacted and kept in molds for a day, then the products are removed from the molds and sent to the finished goods warehouse.
