Abstract
Используетс в промышленности строительных материалов при производстве портландцемента. Сущность изобретени ; в предложенном способе приготовлени добавку в цемент получают обжигом при 500- 700°С в течение 15 мин смеси глиежа и каолиновой глины в соотношении 1:1. Обожженную добавку охлаждают до 100°С и обрабатывают в течение 15 мин 30%-ной серной кислотой в количестве 15% от массы добавки. В жущее готов т совместным помолом 5% добавки и 95% клинкера и гипса. Прочность образцов в возрасте 28 сут при сжатии 61,7-62,4 МПа при изгибе 7,2 - 7,8 МПа. 2 табл.Used in the building materials industry in the production of Portland cement. Summary of the Invention; In the proposed method of preparation, an additive to cement is obtained by calcining at 500-700 ° C for 15 minutes a mixture of giegel and kaolin clay in a 1: 1 ratio. The calcined additive is cooled to 100 ° C and treated for 15 minutes with 30% sulfuric acid in an amount of 15% by weight of the additive. The slurry is prepared by joint grinding of 5% additive and 95% clinker and gypsum. The strength of the samples at the age of 28 days under compression is 61.7-62.4 MPa when bending 7.2 - 7.8 MPa. 2 tab.
Description
Изобретение относитс к технологии получени в жущих строительных материалов при производстве в жущих.This invention relates to a process for the production of building materials in a living process.
Цель изобретени - повышение прочности цемента и расширение сырьевой базы дл производства добавки.The purpose of the invention is to increase the strength of cement and expand the raw material base for the production of the additive.
При осуществлении способа добавку в цемент получают обжигом при 500-700°С в течение 15 мин смеси глиежа и каолиновой глины в соотношении 1:1. При этом глиеж предварительно измельчают до остатка на сите №008 11-12%, а каолиновую глину до 3-4%. Обожженную добавку охлаждают до 100°С и обрабатывают в течение 15 мин 30%-ной серной кислотой в количестве 15% от массы добавки.In the process, an additive in cement is obtained by calcining at 500-700 ° C for 15 minutes a mixture of gliagea and kaolin clay in a 1: 1 ratio. At the same time, gliege is pre-crushed to residue on sieve No. 008 11-12%, and kaolin clay up to 3-4%. The calcined additive is cooled to 100 ° C and treated for 15 minutes with 30% sulfuric acid in an amount of 15% by weight of the additive.
Портландцемент с добавкой в лабораторной чиаровой мельнице путем совместного помола клинкера, гипса и добавки до остатка на сите № 008-9-10%. Ввод добавки в цемент составил 5% от массы цемента.Portland cement with an additive in a laboratory chiar mill by co-grinding of clinker, gypsum and additives to sieve residue No. 008-9-10%. Input additives in cement was 5% by weight of cement.
Химические составы исходных компонентов и обожженных добавок приведены в табл. 1.The chemical composition of the starting components and calcined additives are given in table. one.
Результаты физико-механических испытаний , проведенные по ГОСТ 310.4-81, представлены в табл. 2.The results of physical and mechanical tests conducted according to GOST 310.4-81 are presented in table. 2
Результаты испытаний показывают, что цемент с добавкой, приготовленной по предлагаемому способу, имеет прочность при сжатии в 28 сут 61,7-62,4 МПа, при изгибе 7,2-7,8 МПа, тогда как прототип соответственно 56,7 и 6,1 МПа.The test results show that the cement with the additive prepared by the proposed method has compressive strength at 28 days 61.7-62.4 MPa, with bending 7.2-7.8 MPa, while the prototype, respectively, 56.7 and 6 , 1 MPa.
