Description
Изобретение относитс к промьшшен- ности строительных материалов и может быть использовано в различных отрасл промышленности и гражданского строительства . Известен способ активации воды затворвни бетонной смеси путем обработ ки ее ультразвуком 1. Наиболее близким к изобретению вл етс способ активации воды затворени бетонной смеси путем обработки ее магнитным полем, напр женностью 1750 Э 2. Недостатком известного способа обработки воды затвс енн бетонной снеси вл етс низка прочность бетона . Цель изобретени - повышение прочности бетона. Поставленна цепь достигаетс тем что согласно способу активации воды затрорени бетонной смеси путем магни ной обработки, магнитную обработку осуществл ют при напр женности магнитного пол 2,0-2,5 Э и дополнительно воду затворени обрабатывают ультразвуком интенсивностью 15-25 вт/см и частотой 15-30 кГц. П р и м ер. Готов т бетонные смеси из портландцемента старооскольского н Воскресенского заводов М 400, гранитого щебн крупностью 5-20 мм и речного песка с модулем крупности 2,1 следуницего состава: Цемент 375-390 кг/м Крупный заполнитель до 950 кг/м Вода170-220 л/м Воду затворени предварительно подвергают активации магнитным полем, ультразвуком и совместным одновременным воздействием магнитного пол и ультразвука. Продолжительность активахщн во всех трех случа х одинакова. Бетонную смесь сразу после перемешивани с активированной водой укладываютThe invention relates to the construction materials industry and can be used in various industries and civil engineering. The known method of activating the water of mixing concrete mix by treating it with ultrasound 1. The closest to the invention is the method of activating the mixing water of the concrete mix by treating it with a magnetic field of 1750 Oe 2. The disadvantage of the known method of treating water of the concrete condensate is low concrete strength. The purpose of the invention is to increase the strength of concrete. The delivered chain is achieved by the fact that according to the method of activating the water of splashing the concrete mixture by means of magnesium treatment, the magnetic treatment is carried out at a magnetic field strength of 2.0-2.5 Oe and additionally the mixing water is treated with an ultrasound intensity of 15-25 W / cm and a frequency of 15 -30 kHz. P r and m er. Concrete mixes are prepared from Portland cement of the Star of Oskol n Voskresensky mills M 400, crushed granite with a particle size of 5–20 mm and river sand with a modulus of particle size 2.1 of the following composition: Cement 375–390 kg / m Large aggregate up to 950 kg / m Water 170–220 L / m. The mixing water is preliminarily subjected to activation by a magnetic field, ultrasound, and simultaneous simultaneous exposure to a magnetic field and ultrasound. The duration of the activity is the same in all three cases. Concrete mixture immediately after mixing with activated water is placed
в форму и подвергают уплотнению ударным способом при амплитуде 3,5 мм и частоте соударений 250 уд/мин 4 мин, после чего через нейлоновую тканьinto the mold and subjected to compaction by the impact method with an amplitude of 3.5 mm and a frequency of collisions of 250 beats / min for 4 minutes, then through a nylon fabric
производ т вакуумирование при давлении 0,75-0,9 4-5 мин.vacuuming is performed at a pressure of 0.75-0.9 4-5 minutes.
Результаты испытаний прочности образцов приведены в таблице.The results of testing the strength of the samples are given in the table.
Примечание Водоотделение содержани (в Note Water separation content (in
Экономический эффект от внедрени способа по изобретению составл ет 1 руб. на 1 м бетона. Совместна магнитна и ультразвукова обработка воды затворени позвол ет повысить прочность бетона.The economic effect from the implementation of the method according to the invention is 1 rub. on 1 m of concrete. The combined magnetic and ultrasonic treatment of the mixing water increases the strength of the concrete.
