Abstract
Изобретение относитс к строительным материалам, в частности к способам приготовлени пластифицирующих добавок, используемых в производстве бетонных и железобетонных изделий. Цель изобретени - замедление потери подвижности бетонной смеси во времени. Способ приготовлени пластифицирующей добавки включает обработку 3-10%-ного водного раствора сульфитно-дрожжевой бражки лессом при массовом соотношении (1:5)-(1:10) в течение 40-60 мин с последующим отделением осадка. Подвижность бетонной смеси при расходе добавки 0,5% от массы цемента через 200 мин составл ет 7 см, исходна подвижность - 23 см. 1 табл.The invention relates to building materials, in particular, to methods for preparing plasticizing agents used in the manufacture of concrete and reinforced concrete products. The purpose of the invention is to slow down the loss of mobility of the concrete mixture over time. The method of preparing a plasticizing agent involves treating a 3-10% aqueous solution of sulfite-yeast brews with loess at a mass ratio of (1: 5) - (1:10) for 40-60 minutes, followed by separation of the precipitate. The mobility of the concrete mix at a consumption rate of 0.5% by weight of cement after 200 minutes is 7 cm, the initial mobility is 23 cm. Table 1.
Description
Изобретение -относитс к строительным материалам, в частности к способам приготовлени пластифицирующих добавок, используемых в производстве бетонных и железобетонных изделий.The invention relates to building materials, in particular to methods for preparing plasticizing agents used in the manufacture of concrete and reinforced concrete products.
Цель изобретени - замедление потери подвижности бетонной смеси во времени.The purpose of the invention is to slow down the loss of mobility of the concrete mixture over time.
Пластифицирующую добавку готов т по следующей методике. В 3-10%-ный водный раствор сульфитно-дрожжевой бражки добавл ют сухой лесс, измельченный до фракции Ј0,14 мм и имеющий химический состав, мас.%: SiO 57,5; СаО 12,2; MgO 6,2; А1405-Fez03 5,6; S03 0,05; п.п.п. 18,45, и полученную, смесь перемешивают в течение 40-60 мин. Затем смесь отстаивают и отдел ют раствор от адсорбента. Бетонную смесь готов т из портландцемента М-400,The plasticizer is prepared according to the following procedure. In a 3-10% aqueous solution of a sulfite-yeast brew, dry loess is added, ground to a fraction of ,1 0.14 mm and having a chemical composition, wt%: SiO 57.5; CaO 12.2; MgO 6.2; A1405-Fez03 5.6; S03 0.05; ppt 18.45, and the resulting mixture is stirred for 40-60 minutes. The mixture is then settled and the solution is separated from the adsorbent. Concrete mix is prepared from Portland cement M-400,
гранитного щебн фракции 5-30 мм и гранитного песка фракции 0,14-5 мм при соотношении Ц:П:Щ, равном 1:1,7: :2,5, и В/Ц 0,45.crushed granite fraction 5-30 mm and granite sand fraction 0.14-5 mm with a ratio C: P: U equal to 1: 1.7: 2.5, and V / C 0.45.
Услови приготовлени пластифицирующих добавок по известному и предлагаемому способам, а также физико-механические характеристики бетонной смеси и бетона, полученные без добавки , с известной и предлагаемой представлены в таблице.The conditions for the preparation of plasticizing agents according to the known and proposed methods, as well as the physicomechanical characteristics of the concrete mix and concrete, obtained without an additive, with the known and proposed ones are presented in the table.
