Description
Изобретение относитс к промышленности строительных материалов и може быть и спользовано при изготовлении и ремонте футеровок тепловых агрегатовThe invention relates to the building materials industry and can be used in the manufacture and repair of linings of thermal units.
Цель изобретени - повылюние тер- мостойкости.The purpose of the invention is to increase heat resistance.
Пример. В качестве аглопори- тового заполнител используют щебе- ночно-песчаную смесь фракций 10-20, 5-10 и 0-5 мм при соотношении 0,46: :О,20:О,34 по объему. Марка аглопо- рита по насыпной плотности фракций 10-20, 5-10 и 0-5 мм соответственно 700, 800 и 1000, марка по прочности дл фракций 10-20 и 5-10 мм 250 и 350Example. As an agloporitic aggregate, a crushed stone – sand mixture of fractions 10–20, 5–10 and 0–5 mm is used at a ratio of 0.46:: O, 20: O, 34 by volume. The grade of agloporite by bulk density of the fractions 10-20, 5-10 and 0-5 mm, respectively, 700, 800 and 1000, the grade by strength for the fractions 10-20 and 5-10 mm 250 and 350
Тонкодисперсный гранит получают помолом гранитных отсевов - отходов крупностью от О до 5 мм, получаемых при распиловке и дроблении гранита, до удельной поверхности 2500 - 3000 см2/г.Fine granite is obtained by grinding granite screenings - waste with a grain size from 0 to 5 mm, obtained by sawing and crushing granite, to a specific surface of 2500 - 3000 cm2 / g.
Химический состав аглопорита,гранитных отсевов и феррохромового шла- г.а приведен в табл. 1.The chemical composition of agloporite, granite screenings and ferrochromic slag is given in table. one.
Бетонную смесь приготавливают в смесителе принудительного действи , куда сначала дозируют все сухие компоненты и перемешивают в течение 1- 2 мин. Затем в смеситель заливаютThe concrete mixture is prepared in a forced-action mixer, where all dry components are first metered and mixed for 1–2 minutes. Then the mixer is poured
жидкое стекло плотностью 1,38 г/см liquid glass with a density of 1.38 g / cm
и перемешивают смесь до полной одноand mix the mixture to complete one
