Description
(54) СПОСОБ ИЗГОТОВЛЕНИЯ ДОБА.ВКИ ДЛЯ ЦЕМЕНТА(54) METHOD OF MANUFACTURING AN EXTENSION FOR CEMENT
отходы шахтных кислых вод, превращают в порошок и обжигают в течение 15 мин при 300,1 400 и 500°С.Mine acidic waste water is ground into powder and calcined for 15 minutes at 300.1,400 and 500 ° C.
Химический состав шламовых отходов до и после обжига при 500° приведен в табл. 1.The chemical composition of the sludge waste before and after calcination at 500 ° is given in Table. one.
Таблица 1Table 1
4,038,510,5 7,5 До обжига После обжига при ,543,Б12,4 9,04,038,510,5 7,5 Before firing After firing at, 543, B12.4 9.0
Цементные смеси готов т перемешиванием предварительно изготовленной смеси портландцемента марки 300 (90% и продукта обжига шламов (10%) с песком Вольского карьера в соотношении 1:3 и водой, вз той в количестве 40% от массы цемента с добавкой, образцы из цементных смесей с известной добавкой и по изобретению готов т по стандартной методике дл цементнопесчаных образцов.Cement mixtures are prepared by mixing a prefabricated mixture of Portland cement brand 300 (90% and sludge calcining product (10%) with Volsk open pit sand in a ratio of 1: 3 and water taken in an amount of 40% by weight of cement with an additive; samples from cement mixes with the known additive and in accordance with the invention is prepared according to the standard procedure for cement-sand samples.
Результаты физико-механических испытаний образцов бетона с известной добавкой (1) и по изобретению (2-4) приведены в табл.2.The results of physico-mechanical tests of samples of concrete with a known additive (1) and according to the invention (2-4) are given in table 2.
Таблица2Table 2
По данным испытаний, приведенным в таблице, использование в цементных композици х предлагаемых добавок повьшает прочность составов более чем на 30% по срашнению с прототипом.According to the test data given in the table, the use of the proposed additives in the cement compositions increases the strength of the compositions by more than 30% compared to the prototype.
