Description
Предлагаемый способ имеет целью сравнение консистенций цементных растворов дл производственных надобностей , возникающих при подводном бетонировании по методу „восход щего раствора (см. статью проф. В. И. Дмитриевского , помещенную в газете «Техника от б окт бр 1935 г.). Прилагаемый чертеж иллюстрирует схему определени .The proposed method aims at comparing the consistencies of cement mortars for production needs arising from underwater concreting using the method of rising mortar (see the article by Prof. V. I. Dmitrievsky, published in the newspaper “Technique from October 6, 1935). The attached drawing illustrates the definition scheme.
Широка стекл нна Ц-образна трубка наполн етс через воронку испытуемым цементным раствором, причем выше мениска раствора в коротком колене U-образной трубки заключен воздух . Осторожно действу зажимом 3 на резиновой части короткого колена, довод т мениск до уровн нулевой черты на шкале. Дополн ют воронку до черты Л-А, открыва зажим 3, и, заметив врем на секундомере, позвол ют мениску цементного раствора подн тьс до 25-го делени шкалы; определив врем , потребное дл прохождени раствором определенного пути (независимо от диаметра трубки и, следовательно, объема перемещающегос раствора), наход т относительную консистенцию раствора. Сравнив полученную разность отсчетовThe wide glass U-tube is filled through the funnel with test cement, with air enclosed above the meniscus of the solution in the short bend of the U-tube. I carefully act with clip 3 on the rubber part of the short bend, bringing the meniscus to the level of the zero line on the scale. Complete the funnel to the L-A trait by opening the clamp 3, and, noticing the time on the stopwatch, allow the meniscus of the cement slurry to rise to the 25th scale division; Having determined the time required for the solution to pass a certain path (regardless of the tube diameter and, consequently, the volume of the moving solution), find the relative consistency of the solution. Comparing the resulting sample difference
по секундомеру с такой же разностью, полученной при испытании эталонного раствора, суд т о пригодности раствора дл подводного бетонировани по методу „восход щего раствора. Способ может оказатьс полезным также в цементной и Керамической промышленности при определении косвенным путем в зкости шламма (при пониженной против нормальной влажности) и пластичности глины (при повышенной влажности). Следует заметить, что закон Пуассейл к способу неприменим вследствие отсутстви капилл рности в U-образной трубке . Этим способ отличаетс от способа , осуществл емого на вискозиметрах Оствальда или Уббелода.A stopwatch with the same difference obtained by testing a reference solution is judged on the suitability of the solution for underwater concreting according to the method of an upward solution. The method may also be useful in the cement and ceramic industries when determining indirectly the viscosity of sludge (at low versus normal humidity) and clay plasticity (at high humidity). It should be noted that the Poissal law is not applicable to the method due to the absence of capillary in the U-shaped tube. This method differs from the method carried out with Ostwald or Ubbelohd viscometers.
Предмет изобретени .The subject matter of the invention.
Способ определени консистенции цементных растворов при бетонировании под водой по методу восход щего раствора , отличающийс тем, что консистенцию и пригодность цементного раствора определ ют по скорости подъема его внутри U-образной трубки с произвольным диаметром под действием посто нного давлени . ,The method of determining the consistency of cement mortars during concreting under water using the method of upward mortar, characterized in that the consistency and suitability of cement mortar is determined by the speed of lifting it inside the U-shaped tube with an arbitrary diameter under the action of constant pressure. ,
