Abstract
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 замоченный до набухания в 3% водном растворе перекиси водорода и измельченный до образования гелевидной массы полиакрилат натрия при следующем соотношении компонентов, мас.ч: портландцемент 24-26; кварцевый песок 74-76; указанный полиакрилат натрия 0,1-1,5; вода 12-14.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 hydrogen peroxide soaked to swelling in a 3% aqueous solution and crushed to form a gel-like mass of sodium polyacrylate in the following ratio components, parts by weight: Portland cement 24-26; silica sand 74-76; the specified sodium polyacrylate 0.1-1.5; water 12-14.
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 3% водном растворе перекиси водорода, 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 a 3% aqueous solution of hydrogen peroxide, 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.
