Description

Изобретение относится к области производства строительных материалов и касается составов сырьевых смесей для изготовления кирпича, который может быть использован для постройки малоэтажных зданий. The invention relates to the field of production of building materials and relates to compositions of raw mixtures for the manufacture of bricks, which can be used for the construction of low-rise buildings.

Известна сырьевая смесь для изготовления кирпича, включающая, вес.ч.: древесные опилки 2; кварцевый песок 2; портландцемент 2; известковое тесто 3 [1].Known raw mix for the manufacture of bricks, including, parts by weight: sawdust 2; silica sand 2; Portland cement 2; lime dough 3 [1].

Задача изобретения состоит в повышении морозостойкости кирпича, получаемого из сырьевой смеси.The objective of the invention is to increase the frost resistance of the brick obtained from the raw mix.

Технический результат достигается тем, что сырьевая смесь для изготовления кирпича, включающая древесные опилки, кварцевый песок, портландцемент, дополнительно включает лигносульфонат технический модифицированный ЛСТМ-2 или ЛГМ при следующем соотношении компонентов, мас.%: просеянные через сито №5 древесные опилки 5,0-7,0; кварцевый песок 62,75-69,8; портландцемент 25,0-30,0; лигносульфонат технический модифицированный ЛСТМ-2 или ЛГМ 0,2-0,25, при водоцементном отношении 0,5-0,55. В таблице приведены составы сырьевой смеси.The technical result is achieved by the fact that the raw material mixture for making bricks, including wood sawdust, quartz sand, Portland cement, additionally includes a technical modified lignosulfonate LSTM-2 or LGM in the following ratio of components, wt.%: Wood sawdust sifted through sieve No. 5 5.0 -7.0; silica sand 62.75-69.8; Portland cement 25.0-30.0; Technical modified lignosulfonate LSTM-2 or LGM 0.2-0.25, with a water-cement ratio of 0.5-0.55. The table shows the composition of the raw mix.

Лигносульфонат технический ЛСТМ-2 представляет собой продукт взаимодействия натриевых лигносульфонатов с мочевино-формальдегидной смолой. Лигносульфонаты ЛСТМ-2, ЛГМ выпускаются промышленностью для приготовления пластичных смесей [2].Technical lignosulfonate LSTM-2 is a product of the interaction of sodium lignosulfonates with a urea-formaldehyde resin. LSTM-2, LGM lignosulfonates are produced by the industry for the preparation of plastic mixtures [2].

Компоненты смеси дозируют в требуемых количествах, смешивают. Из полученной смеси формуют (по литьевой технологии с применением форм) кирпич. Готовые изделия выдерживают в формах до отверждения, после чего извлекают из форм и отправляют на склад готовой продукции.The components of the mixture are dosed in the required quantities, mixed. Brick is formed from the resulting mixture (by injection technology using molds). Finished products are kept in molds until cured, after which they are removed from the molds and sent to the finished goods warehouse.
