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. %: цемент 22,0-40,0; микрокремнезем 3,0-4,0; пластификатор 0,3-0,9; базальтовое волокно длиной до 9 мм 1,5-2,0; кварцевый песок 55,0-60,0; вода - остальное [1].Known raw mix for the manufacture of concrete, containing, by weight. %: cement 22.0-40.0; silica fume 3.0-4.0; plasticizer 0.3-0.9; basalt fiber up to 9 mm long 1.5-2.0; silica sand 55.0-60.0; 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, базальтовое волокно длиной до 9 мм, кварцевый песок, воду, дополнительно включает 3% водный раствор перекиси водорода при следующем соотношении компонентов, мас. %: портландцемент 17,0-19,0; микрокремнезем 0,5-0,9; базальтовое волокно длиной до 9 мм 0,5-0,9; кварцевый песок 62,6-64,6; 3% водный раствор перекиси водорода 2,0-3,0; вода 14,0-15,0.The technical result is achieved in that the raw material mixture for the manufacture of concrete containing Portland cement, silica fume, basalt fiber up to 9 mm long, silica sand, water, additionally includes a 3% aqueous solution of hydrogen peroxide in the following ratio of components, wt. %: Portland cement 17.0-19.0; silica fume 0.5-0.9; basalt fiber up to 9 mm long 0.5-0.9; silica sand 62.6-64.6; 3% aqueous hydrogen peroxide solution 2.0-3.0; water 14.0-15.0.

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

Подготавливают, дозируют и смешивают портландцемент, микрокремнезем, кварцевый песок, базальтовое волокно, добавляют воду и 3% водный раствор перекиси водорода и вновь смешивают. Полученной бетонной смесью заполняют металлические формы, уплотняют смесь и выдерживают ее в формах до затвердевания. Затем изделия извлекают из форм.Portland cement, silica fume, silica sand, basalt fiber are prepared, dosed and mixed, water and a 3% aqueous solution of hydrogen peroxide 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.
