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.%: глину монтмориллонитоваую 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 молотый уголь, молотый доломит, глину монтмориллонитовую, дополнительно содержит карбоксиметилцеллюлозу и молотый доменный шлак, при следующем соотношении компонентов, мас.%: указанный уголь 5,0-6,0; указанный доломит 30,0-35,0; карбоксиметилцеллюлоза 0,05-0,1; указанный доменный шлак 5,0-7,0; глина монтмориллонитовая - остальное.The technical result is achieved in that the mixture for the production of porous aggregate containing ground coal, ground dolomite, clay montmorillonite, additionally contains carboxymethyl cellulose and ground blast furnace slag, in the following ratio, wt.%: The specified coal is 5.0-6.0; said dolomite 30.0-35.0; carboxymethyl cellulose 0.05-0.1; the specified blast furnace slag 5.0-7.0; montmorillonite clay - the rest.
В таблице приведены составы шихты.The table shows the composition of the charge.
В составе шихты для производства пористого заполнителя используют глины монтмориллонитовые, включающие Al-монтмориллонит и Fe-монтмориллонит (нонтронит). Удельная поверхность глины монтмориллонитовой 2500-3500 см2/г.Montmorillonite clays, including Al-montmorillonite and Fe-montmorillonite (nontronite) are used in the mixture for the production of porous aggregate. The specific surface area of montmorillonite clay is 2500-3500 cm 2 / g.
Доменный шлак характеризуется следующим химическим составом, мас.%: SiO2 36,0-41,0; Al2O3 8,0-11,0; FeO 0,2-0,7; CaO 40,0-48,0; MgO 6,0-10,0; MnO 0,1-1,0; SO3 0,5-2,2.Blast furnace slag is characterized by the following chemical composition, wt.%: SiO 2 36,0-41,0; Al 2 O 3 8.0-11.0; FeO 0.2-0.7; CaO 40.0-48.0; MgO 6.0-10.0; MnO 0.1-1.0; SO 3 0.5-2.2.
Компоненты сырьевой смеси дозируют в требуемых количествах. Уголь, доломит, доменный шлак размалывают до удельной поверхности 2500-3500 см2/г, в данном случае до 3200 см2/г, добавляют глину монтмориллонитовую, карбоксиметилцеллюлозу и смешивают. Полученную шихту увлажняют до 20-25%, в данном случае увлажняют до 25%, формуют из нее пластическим способом гранулы, которые сушат и обжигают при температуре 900-1000°С, в данном случае при 950°С.The components of the raw mix are metered in the required quantities. Coal, dolomite, blast furnace slag are ground to a specific surface of 2500-3500 cm 2 / g, in this case up to 3200 cm 2 / g, montmorillonite clay, carboxymethyl cellulose are added and mixed. The resulting mixture is moistened up to 20-25%, in this case, moistened up to 25%, granules are dried from it, which are dried and fired at a temperature of 900-1000 ° C, in this case at 950 ° C.
