Abstract
Description
Изобретение относится к производству пористых заполнителей для бетонов.The invention relates to the production of porous aggregates for concrete.
Известна шихта для производства пористого заполнителя, содержащая, мас.%: глина монтмориллонитовая 35,0-38,0; уголь 5,0-6,0; доломит 36,0-50,0 [1].A known mixture for the production of porous aggregate, containing, wt.%: Clay montmorillonite 35,0-38,0; coal 5.0-6.0; dolomite 36.0-50.0 [1].
Задачей изобретения является повышение прочности пористого заполнителя, полученного из шихты.The objective of the invention is to increase the strength of the porous aggregate obtained from the mixture.
Технический результат достигается тем, что шихта для производства пористого заполнителя, содержащая глину монтмориллонитовую, уголь, доломит, дополнительно содержит соду кальцинированную при следующем соотношении компонентов, мас.%: глина монтмориллонитовая 69,0-79,0; уголь 5,0-6,0; доломит 15,0-20,0; сода кальцинированная 1,0-2,0.The technical result is achieved in that the mixture for the production of porous aggregate containing montmorillonite clay, coal, dolomite, additionally contains soda ash in the following ratio, wt.%: Montmorillonite clay 69.0-79.0; coal 5.0-6.0; dolomite 15.0-20.0; soda ash 1.0-2.0.
В таблице приведены составы шихты.The table shows the composition of the charge.
В составе шихты для производства пористого заполнителя используют шины монтмориллонитовые, включающие Al-монтмориллонит и Fe-монтмориллонит (нонтронит) с удельной поверхностью 2500-3500 см2/г. Компоненты сырьевой смеси дозируют в требуемых количествах. Уголь и доломит размалывают до удельной поверхности 2500-3000 см2/г, добавляют глину монтмориллонитовую, соду кальцинированную и смешивают. Полученную шихту увлажняют до 20-25%, формуют из нее пластическим способом гранулы, которые сушат и обжигают при температуре 900-1000°С.Montmorillonite tires, including Al-montmorillonite and Fe-montmorillonite (nontronite) with a specific surface of 2500-3500 cm 2 / g, are used as a part of the mixture for the production of porous aggregate. The components of the raw mix are metered in the required quantities. Coal and dolomite are ground to a specific surface of 2500-3000 cm 2 / g, montmorillonite clay, soda ash are added and mixed. The resulting mixture is moistened to 20-25%, granules are formed from it in a plastic way, which are dried and calcined at a temperature of 900-1000 ° C.
При приготовлении образцов шихты, имеющей составы, представленные в таблице, уголь и доломит размалывают до крупности 2700 см2/г, шихту увлажняют до 27%, а сушку и обжиг гранул ведут при температуре 950°С.When preparing samples of the mixture having the compositions shown in the table, the coal and dolomite are grinded to a particle size of 2700 cm 2 / g, the mixture is moistened to 27%, and the granules are dried and fired at a temperature of 950 ° C.
