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 снижении расхода цемента в составе сырьевой смеси для изготовления бетона.The objective of the invention is to reduce the consumption of cement in the composition of the raw mix for the manufacture of concrete.

Технический результат достигается тем, что сырьевая смесь для изготовления бетона, содержащая цемент, заполнитель, пластификатор, воду, в качестве заполнителя включает андезитовую муку, в качестве пластификатора - суперпластификатор С-3 и дополнительно полиэтиленсилоксан при следующем соотношении компонентов, мас. %: портландцемент или шлакопортландцемент 17,2-20,3; андезитовая мука 62,0-64,0,0; суперпластификатор С-3 1,1-1,3; вода 14,0-15,0; полиэтиленсилоксан 2,2-2,4.The technical result is achieved in that the raw mix for the manufacture of concrete, containing cement, aggregate, plasticizer, water, includes andesitic flour as a filler, C-3 superplasticizer and additionally polyethylene siloxane in the following ratio of components, wt. %: Portland cement or slag Portland cement 17.2-20.3; andesite flour 62.0-64.0.0; superplasticizer C-3 1.1-1.3; water 14.0-15.0; polyethylene siloxane 2.2-2.4.

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

Подготавливают, дозируют и смешивают портландцемент или шлакопортландцемент, андезитовую муку, добавляют воду, суперпластификатор С-3 (получаемый на базе продуктов конденсации нафталинсульфокислоты и формальдегида [2]), полиэтиленсилоксан 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 or slag Portland cement, andesitic flour are prepared, dosed and mixed, water, C-3 superplasticizer (obtained from the condensation products of naphthalenesulfonic acid and formaldehyde [2]) are added, polyethylene siloxane 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.
