Description
Изобретение относитс к технологии производства строительных материалов и может быть использовано при производстве бетона.The invention relates to the production technology of building materials and can be used in the production of concrete.
Наиболее близким к предлагаемому вл етс способ приготовлени бетонной смеси , включающий обработку заполнител водным раствором продуктов конденсации нафталинсульфокислоты с формальдегидом или алкилнафталинсульфокислоты с формальдегидом , или сульфированного продукта конденсации меламина с формальдегидом.Closest to the present invention is a method for preparing a concrete mix, which includes treating the aggregate with an aqueous solution of naphthalene sulfonic acid condensation products with formaldehyde or alkyl naphthalene sulfonic acid with formaldehyde, or sulfonated condensation product of melamine with formaldehyde.
Однако технологи обработки сложна, так как включает сначала перемешивание заполнителей с 50-70% раствора пластификатора , затем высушивание при 20-70°С и введение остальных 30-50% раствора. Концентраци продуктов конденсации велика - 5-50%. Повышение прочности недостаточно - не выше 27%.However, processing techniques are complex, as they first involve mixing the aggregates from a 50-70% plasticizer solution, then drying at 20-70 ° C and introducing the remaining 30-50% solution. The concentration of condensation products is high - 5-50%. Increased strength is not enough - no higher than 27%.
Целью изобретени вл етс упрощение технологии, экономи пластификатора, сокращение длительности пропаривани бетона.The aim of the invention is to simplify the technology, save the plasticizer, reduce the duration of concrete steaming.
Пример. Гранитный щебень фракции 5-20 мм и кварцевый песок с Мкр 1,1 тщательно перемешивают с 80-90% воды затворени , содержащей 10 2% по отношению к заполнителю продуктов конденсации нафталинсульфокислоты с формальдегидом или алкилнафталинсульфокислоты с формальдегидом , или сульфированного продукта конденсации меламина с формальдегидом в течение 1,0-1,5 мин, затем ввод т цемент и оставшиес 10-20% воды затворени и осуществл ют окончательное перемешивание.Example. Granite crushed stone of 5–20 mm fraction and quartz sand with Mkr 1.1 is thoroughly mixed with 80–90% of water containing 10–2% with respect to aggregate of naphthalene sulfonic acid condensation products with formaldehyde or alkyl naphthalene sulfide with formaldehyde, or sulfated melamine condensation product with formaldehyde for 1.0-1.5 minutes, then cement and the remaining 10-20% of the mixing water are introduced and the final mixing is carried out.
Состав бетонной смеси кг/м3: щебень 1220, песок 670, цемент 326, .55-0,57, в зависимости от подвижности смеси. O.K. 5 см. Размер образцов 100x100x100 мм. Режим пропаривани 2+6+2 и 2+5+2 ч. Испытани бетонной смеси и образцов бетона провод т по стандартным методикам.The composition of the concrete mix kg / m3: crushed stone 1220, sand 670, cement 326, .55-0.57, depending on the mobility of the mixture. O.K. 5 cm. Sample size 100x100x100 mm. The steaming mode is 2 + 6 + 2 and 2 + 5 + 2 hours. Concrete and concrete samples are tested by standard methods.
Результаты испытаний представлены в таблице.The test results are presented in the table.
