Description

Изобретение касается составов сырьевых смесей, используемых в производстве кирпича для малоэтажного строительства.The invention relates to compositions of raw mixtures used in the manufacture of bricks for low-rise construction.

Известна сырьевая смесь следующего состава, мас.%: фосфогипс 15,0-40,0; кремнистая осадочная порода 25,0-50,0; топливная зола 30,0-45 [1].Known raw mixture of the following composition, wt.%: Phosphogypsum 15.0-40.0; siliceous sedimentary rock 25.0-50.0; fuel ash 30.0-45 [1].

Задачей изобретения является повышение водостойкости кирпича, полученного из сырьевой смеси.The objective of the invention is to increase the water resistance of the brick obtained from the raw mix.

Технический результат достигается тем, что сырьевая смесь для производства кирпича, содержащая фосфогипс и топливную золу, дополнительно включает нарезанное на отрезки 3-10 мм стекловолокно при следующем соотношении компонентов, мас.%: фосфогипс 45,0-52,0; топливная зола 47,0-50,0; стекловолокно 1,0-5,0.The technical result is achieved in that the raw material mixture for the production of bricks, containing phosphogypsum and fuel ash, further includes cut into pieces of 3-10 mm fiberglass in the following ratio of components, wt.%: Phosphogypsum 45.0-52.0; fuel ash 47.0-50.0; fiberglass 1.0-5.0.

В таблице приведены составы сырьевой смеси для производства кирпича.The table shows the composition of the raw mix for the production of bricks.

В составе керамической массы используют фосфогипс, состоящий на 80-90% из двуводного сульфата кальция с примесями фосфатов, фторидов и кремнезема. Топливная зола имеет состав, мас.%: SiO2 40,7; Al2O3 15,8; Fe2O3 13,5; CaO 8,9; MgO 4,3; Na2O+K2O 3,8; SO3 1,4; п.п.п.8,5.As part of the ceramic mass, phosphogypsum is used, consisting of 80-90% of two-water calcium sulfate with impurities of phosphates, fluorides and silica. Fuel ash has a composition, wt.%: SiO 2 40.7; Al 2 O 3 15.8; Fe 2 O 3 13.5; CaO 8.9; MgO 4.3; Na 2 O + K 2 O 3.8; SO 3 1,4; pp. 8.5.

Компоненты дозируют в требуемых количествах. Фосфогипс смешивают с топливной золой и предварительно нарезанным на отрезки длиной 3-10 мм стекловолокном. Массу увлажняют до 23-26% и формуют из нее кирпич, который выдерживают при температуре 15-25°С в течение 1-3 сут., а затем упаковывают.The components are dosed in the required amounts. Phosphogypsum is mixed with fuel ash and glass fiber pre-cut into 3-10 mm lengths. The mass is moistened to 23-26% and a brick is formed from it, which is held at a temperature of 15-25 ° C for 1-3 days, and then packaged.
