Description

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

Известна сырьевая смесь для изготовления бетона, содержащая, мас.%: портландцемент 25,0-30,0; микрокремнезем 3,0-4,0; кварцевый песок 55,0-60,0; пластификатор 0,3-0,9; базальтовое волокно длиной 0,3-0,9; вода - остальное [1].Known raw mix for the manufacture of concrete, containing, wt.%: Portland cement 25.0-30.0; silica fume 3.0-4.0; silica sand 55.0-60.0; plasticizer 0.3-0.9; basalt fiber 0.3-0.9 long; water - the rest [1].

Задача изобретения состоит в повышении морозостойкости бетона.The objective of the invention is to increase the frost resistance of concrete.

Технический результат достигается тем, что сырьевая смесь для изготовления бетона, содержащая портландцемент, микрокремнезем, кварцевый песок, воду, дополнительно включает замоченный в воде до набухания и измельченный до образования гелеподобной массы полиакрилат натрия при следующем соотношении компонентов, мас.%: портландцемент 23,0-23,3; микрокремнезем 4,5-5,0; кварцевый песок 59,0-59,9; указанный полиакрилат натрия 0,1-0,2; вода 12,0-13,0.The technical result is achieved in that the raw mix for the manufacture of concrete, containing Portland cement, silica fume, silica sand, water, further includes soaked in water until swelling and crushed to form a gel-like mass of sodium polyacrylate in the following ratio, wt.%: Portland cement 23.0 -23.3; silica fume 4,5-5,0; silica sand 59.0-59.9; the specified sodium polyacrylate 0.1-0.2; water 12.0-13.0.

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

Figure 00000001

Полиакрилат натрия в виде гранул замачивают в воде (используют часть воды для затворения) и выдерживают до набухания (примерно 1 сутки). Затем гранулы измельчают до образования гелеподобной массы. Подготавливают, дозируют и смешивают портландцемент, микрокремнезем, кварцевый песок, добавляют воду, подготовленный полиакрилат натрия и вновь смешивают. Полученной бетонной смесью заполняют металлические формы, уплотняют смесь и выдерживают ее в формах до затвердевания. Затем изделия извлекают из форм.Sodium polyacrylate in the form of granules is soaked in water (use part of the water for mixing) and incubated until swelling (about 1 day). Then the granules are crushed to form a gel-like mass. Portland cement, silica fume, silica sand are prepared, dosed and mixed, water, prepared sodium polyacrylate are added and mixed again. The resulting concrete mixture is filled into metal molds, the mixture is compacted and kept in molds until it hardens. Then the products are removed from the molds.
