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 - повышение 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 агар при следующем соотношении компонентов, мас.ч.: портландцемент 24-26; кварцевый песок 74-76; агар 0,05-0,5; вода 12-14.The technical result is achieved in that the raw mix for the manufacture of fine concrete containing Portland cement, quartz sand, a water-retaining additive, water, as a water-holding additive contains agar in the following ratio of components, parts by weight: portland cement 24-26; silica sand 74-76; agar 0.05-0.5; 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. Портландцемент смешивают с кварцевым песком. Агар растворяют в воде, которую добавляют в смесь сухих компонентов. 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. Portland cement is mixed with quartz sand. Agar is dissolved in water, which is added to the mixture of dry components. 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.
