Description
(54) КЛИНКЕР ДЛЯ ПОЛУЧЕНИЯ РАСШИРЯЮЩЕГОСЯ ЦЕМЕНТА мрамор 83,5 вес.% и сульфатные отходы - фторо гипс - 2,5 вес.%. После совместного помола сырьевую смесь брикетируют и подвергают обжигу при 200-1300 С с изотермической выдержкой 45 мин. В результате обжига в интервале температур 12(Ю., 1230-1260 С, ПбО-ООО С получают соответствошо, клинкеры К-1, К-2, К-3. . В . 1 приведен минералогический состав клинкеров. Таблица 1 Продолжение табл.1 Сульфоалюминат кальци 20,015,010,0 Сульфат кальци 8,0.5,53,0 Окись кальци 5,03,01,0 Фторалюминат кальци йО,07,55,0 Полученный клинкер размапьшают до удельной поверхности 3000 совместно с природным гипсом. В табл. 2 приведены .показатели прочности при сжатии расшир ющегос цемента. В табл. 3 приведена степень расширени цемента. Таблнца2(54) CLINKER FOR OBTAINING EXTENDING CEMENT marble 83.5 wt.% And sulphate waste - fluorine gypsum - 2.5 wt.%. After co-grinding, the raw mix is preformed and fired at 200-1300 ° C with isothermal aging for 45 minutes. As a result of roasting in the temperature range of 12 (Yu., 1230-1260 C, PBO-LLC C is obtained respectively, clinkers K-1, K-2, K-3.. V. 1 shows the mineralogical composition of the clinkers. Table 1 Continued Table. 1 Calcium sulfoaluminate 20,015,010,0 Calcium sulphate 8,0.5,53,0 Calcium oxide 5,03,01,0 Calcium fluoroaluminate, 07,55,0 The resulting clinker is mottled to a specific surface 3000 together with natural gypsum. Table 2 shows . The compressive strength indicators of expanding cement Table 3 shows the degree of expansion of the cement.
Таблица 3Table 3
Результаты испытаний, представленные в таблицах , иллюстрируют повышение прочности цемента в 3-х и 7-ми суточном возрасте при тверденни в воде на 30% и 25%, прн воздушно-влажном твердении (относительна влажность 50%) на 60% и 50%, н увеличение относительного удлинени на 20-30%.The test results presented in the tables illustrate an increase in the strength of cement at the 3rd and 7th day old at 30% and 25% hardening in water, 60% and 50% air-wet hardening (relative humidity 50%), n an increase in the relative elongation of 20-30%.
