Abstract
Description
Изобретение относится к промышленности строительных материалов, в частности к производству бетонов.The invention relates to the construction materials industry, in particular to the production of concrete.
Известно введение в состав бетонной смеси водоудерживающих добавок в виде сухих гранул (порошка) [1]. Введение в таком виде полиакрилата натрия в состав бетонной смеси приводит к внутренним напряжениям в структуре получаемого бетона.It is known the introduction to the composition of the concrete mixture of water-retaining additives in the form of dry granules (powder) [1]. The introduction of sodium polyacrylate in this form into the concrete mix leads to internal stresses in the structure of the resulting concrete.
Задача изобретения состоит во введении полиакрилата натрия в состав бетонной смеси с повышением качества бетона.The objective of the invention is to introduce sodium polyacrylate in the composition of the concrete mixture with an increase in the quality of concrete.
Технический результат достигается тем, что способ подготовки полиакрилата натрия для введения в состав бетонной смеси, предусматривает замачивание гранул полиакрилата натрия в воде при температуре 15-40°С, выдерживание их до набухания в течение 24-36 часов с последующим измельчением до получения гелеподобной массы.The technical result is achieved by the fact that the method of preparing sodium polyacrylate for introduction into the concrete mixture involves soaking the sodium polyacrylate granules in water at a temperature of 15-40 ° C, keeping them until swelling for 24-36 hours, followed by grinding to obtain a gel-like mass.
Технический результат достигается также тем, что способ подготовки полиакрилата натрия для введения в состав бетонной смеси предусматривает замачивание гранул полиакрилата натрия в 3%-ном водном растворе перекиси водорода при температуре 15-40°С, выдерживание их до набухания в течение 24 или 36 часов с последующим измельчением до получения гелеподобной массы.The technical result is also achieved by the fact that the method of preparing sodium polyacrylate for introduction into the concrete mix involves soaking the granules of sodium polyacrylate in a 3% aqueous solution of hydrogen peroxide at a temperature of 15-40 ° C, keeping them until swelling for 24 or 36 hours subsequent grinding to obtain a gel-like mass.
Способ поясняется примерами.The method is illustrated by examples.
1. Полиакрилат натрия в виде гранул замачивают в воде при температуре 15°С и выдерживают до набухания (24-36 ч). Затем гранулы измельчают до образования гелеподобной массы.1. Sodium polyacrylate in the form of granules is soaked in water at a temperature of 15 ° C and maintained until swelling (24-36 hours). Then the granules are crushed to form a gel-like mass.
2. Полиакрилат натрия в виде гранул замачивают в воде при температуре 40°С и выдерживают до набухания (24 ч). Затем гранулы измельчают до образования гелеподобной массы.2. Sodium polyacrylate in the form of granules is soaked in water at a temperature of 40 ° C and maintained until swelling (24 hours). Then the granules are crushed to form a gel-like mass.
3. Полиакрилат натрия в виде гранул замачивают в 3%-ном водном растворе перекиси водорода при температуре 15°С и выдерживают до набухания (36 ч). Затем гранулы измельчают до образования гелеподобной массы.3. Sodium polyacrylate in the form of granules is soaked in a 3% aqueous solution of hydrogen peroxide at a temperature of 15 ° C and kept until swelling (36 h). Then the granules are crushed to form a gel-like mass.
4. Полиакрилат натрия в виде гранул замачивают в 3%-ном водном растворе перекиси водорода при температуре 40°С и выдерживают до набухания (24 ч). Затем гранулы измельчают до образования гелеподобной массы.4. Sodium polyacrylate in the form of granules is soaked in a 3% aqueous solution of hydrogen peroxide at a temperature of 40 ° C and kept until swelling (24 hours). Then the granules are crushed to form a gel-like mass.
Подготавливают, дозируют и смешивают в массовом соотношении 1:3 портландцемент и кварцевый песок, добавляют воду (при соблюдении водоцементного отношения 0,45-0,5), подготовленный полиакрилат натрия и вновь смешивают. Полученной бетонной смесью заполняют металлические формы, уплотняют смесь и выдерживают ее в формах до затвердевания. Затем изделия извлекают из форм. Введение подготовленного по предложенному способу полиакрилата натрия в количестве 0,5% от массы воды затворения в бетонную смесь вышеуказанного состава приводит к повышению прочности бетона (в возрасте 28 сут) до 15%, снижению его водопоглощения до 2,5 раз.Portland cement and quartz sand are prepared, dosed and mixed in a mass ratio of 1: 3, water is added (subject to a water-cement ratio of 0.45-0.5), the prepared sodium polyacrylate and mixed again. The resulting concrete mixture is filled into metal molds, the mixture is compacted and kept in molds until it hardens. Then the products are removed from the molds. The introduction of sodium polyacrylate prepared according to the proposed method in an amount of 0.5% by weight of mixing water into the concrete mixture of the above composition leads to an increase in concrete strength (at the age of 28 days) up to 15%, reduction in its water absorption up to 2.5 times.
