Abstract
Изобретение относитс к производству строительных материалов, в частности к способам приготовлени добавок, используемых в производстве бетонных и железобетонных изделий. Цель изобретени - повышение прочности бетона при нормальных и естественных услови х твердени . Добавку получают путем обработки стеблей хлопчатника 0,5-1,0%-ным раствором едкого натра при массовом соотношении стебли хлопчатника: окись натри 1:0,2-0,5. Прочность бетона с добавкой при нормальных и естественных услови х твердени после 28 сут 52,9 и 45,9 МПа, контрольного образца 34,2 и 28,7 МПа соответственно. 1 табл.The invention relates to the production of building materials, in particular, to methods for preparing additives used in the manufacture of concrete and reinforced concrete products. The purpose of the invention is to increase the strength of concrete under normal and natural hardening conditions. The additive is obtained by treating the cotton stalks with a 0.5-1.0% sodium hydroxide solution at a mass ratio of cotton stalks: sodium oxide 1: 0.2-0.5. The strength of concrete with the addition under normal and natural conditions of hardening after 28 days is 52.9 and 45.9 MPa, the control sample is 34.2 and 28.7 MPa, respectively. 1 tab.
Description
Изобретение относитс к производству строительных материалов, в частности к способам приготовлени добавок , используемых в производстве бетонных и железобетонных изделий.The invention relates to the production of building materials, in particular, to methods for preparing additives used in the manufacture of concrete and reinforced concrete products.
Целью изобретени вл етс повышение прочности бетона при нормальных и естественных услови х твердени .The aim of the invention is to increase the strength of concrete under normal and natural hardening conditions.
Добавку по предлагаемому способу готов т следующим образом.The additive according to the proposed method is prepared as follows.
К измельченным до фракции менее 5 мм стебл м хлопчатника добавл ют 0,5-1%-ный раствор едкого натра, затем полученную смесь кип т т в течение 40-60 мин. и- после охлаждени смеси раствор отдел ют от волокнистой массы фильтрованием.A 0.5-1% sodium hydroxide solution is added to the cotton stalks, crushed to a fraction less than 5 mm, then the mixture is boiled for 40-60 minutes. and after cooling the mixture, the solution is separated from the pulp by filtration.
Бетонную добавку готов т на основе портлавдцемента, гранитного песка фракции 0,14-5 мм и гранитного щебн фракции 5-20 мм при следующем соотношении компонентов Ц:П:Щ 1:1,7:3,45 и ,45. Добавку ввод т в бетонную смесь с водой затворени в количестве 0,05-0,5% от массы цемента (на сухой продукт).Concrete additive is prepared on the basis of portland cement, granite sand fraction of 0.14-5 mm and granite rubble fraction of 5-20 mm in the following ratio of components C: P: Sch 1: 1.7: 3.45 and 45. The additive is introduced into the concrete mix with mixing water in an amount of 0.05-0.5% by weight of cement (per dry product).
Примеры выполнени способа и свойства бетонных смесей и бетона с пред- лагаемой добавкой представлены в таблице .Examples of the method and properties of concrete mixes and concrete with the proposed additive are presented in the table.
