Description

Изобретение относится к составам масс для изготовления силикатного кирпича, строительных блоков.The invention relates to compositions of the masses for the manufacture of silicate brick, building blocks.

Известна сырьевая смесь для изготовления силикатного кирпича, содержащая, мас.%: известь 6,0-8,0; кальцито-волластонитовая руда 10,0-20,0; кварцевый песок - остальное [1].Known raw mix for the manufacture of silicate brick, containing, wt.%: Lime 6.0-8.0; calcite-wollastonite ore 10.0-20.0; quartz sand - the rest [1].

Задача изобретения состоит в повышении прочности изделий.The objective of the invention is to increase the strength of products.

Технический результат достигается тем, что сырьевая смесь для изготовления силикатного кирпича, включающая негашеную известь, кальцито-волластонитовую руду, кварцевый песок, согласно изобретению дополнительно содержит пемзовый песок при следующем соотношении компонентов, мас.%: негашеная известь 8,0-9,0; измельченная до прохождения через сетку №0,63 кальцито-волластонитовая руда 8,0-9,0; измельченный до прохождения через сетку №0,63 пемзовый песок 8,0-9,0; измельченный до прохождения через сетку №0,63 кварцевый песок - остальное.The technical result is achieved in that the raw mixture for the manufacture of silicate brick, including quicklime, calcite-wollastonite ore, quartz sand, according to the invention additionally contains pumice sand in the following ratio of components, wt.%: Quicklime 8.0-9.0; crushed before passing through the mesh No. 0.63 calcite-wollastonite ore 8.0-9.0; crushed before passing through the mesh No. 0.63 pumice sand 8.0-9.0; crushed quartz sand before passing through mesh No. 0.63 - the rest.

Компоненты дозируют в требуемых количествах. Кальцито-волластонитовую руду, кварцевый песок, пемзовый песок по отдельности измельчают до прохождения через сетку №0,63, смешивают с молотой (до остатка не более 10% на сите №008) негашеной известью (I-II сорт), затем добавляют воду, вновь смешивают и выдерживают до полного гашения извести. Из полученной смеси с влажностью 6,5-7,5% прессуют под давлением 15-17 МПа кирпич, который подвергают автоклавной обработке в атмосфере насыщенного пара при давлении 0,9-1,1 МПа и температуре 175-180°С в течение 6-7 ч.The components are dosed in the required amounts. Calcite-wollastonite ore, quartz sand, pumice sand are separately crushed before passing through a mesh No. 0.63, mixed with ground (to a residue of not more than 10% on a mesh No. 008) quicklime (grade I-II), then water is added, again mixed and kept until the lime is completely extinguished. From the mixture with a moisture content of 6.5-7.5%, a brick is pressed under pressure of 15-17 MPa, which is autoclaved in a saturated steam atmosphere at a pressure of 0.9-1.1 MPa and a temperature of 175-180 ° C for 6 -7 hours
