Description
В маосив НЫ:х гидротехнических железобетоИНых сооружени х должен Примен тьс специальный цемент .In the mains: HY: hydraulic engineering reinforced concrete structures must use special cement.
Дл получени бетона, удовлетвор ющего требованию водоиепрокицаемости , при-ходитс при ручной укладке расходовать от 280 до 300 кг цемента на кубический метр бетона, незащксймо от актиЕкости цемента. При таких количествах цемента в бетоне развй-ваютс весьма з-начительные температуры, вследствие большого выделени тепла в процессе гидратации портландцемента , а это, в свою очередь, влечет за собой нарушение монолиТНОсти; бетона и по вление тре . щи«.In order to obtain concrete that meets the requirement of water-proofing, it comes with manual laying to spend from 280 to 300 kg of cement per cubic meter of concrete, not dependent on the activation of cement. With such amounts of cement in concrete, very high temperatures develop due to the large amount of heat released during the process of hydration of Portland cement, and this, in turn, entails a violation of the monolith; concrete and the appearance of thre. shchi ".
С увеличением количества цемента , затраченного на один кубометр бетона, возрастают и усадоч;ные влени .With an increase in the amount of cement spent per cubic meter of concrete, shrinkage increases;
Таки1М образом требование плотности и. водонепроницаемости бетона гидротехнических железобетонных сооружений ведет к высоко-му расходу цемента, а это обсто тельcTBiO вл етс .щричиной нарушени монолитности бетона.Thus the requirement of density and. The waterproofness of concrete in hydraulic engineering reinforced concrete structures leads to a high cement consumption, and this circumstance TBiO causes a violation of the solidity of concrete.
Авторами, разработан способ поjtyHSHHiH трехкомпонентного цемента - в жущего, удовлетвор ющегоThe authors have developed a method for using three-component cement - imbued, satisfying
требовани м практики массивного железобетонного гидротехнического строительства, заключающийс в том, что смесь, состо щую -из портланд-цементного клинкера в количестве 40-60%, кислой гидра1влической добавки или доменного гранулированиото шлака в количестве 13-20% и 20-47% твердой инертной Породы, как-то: кварцевого песка , маршалита, твердого известн ка и др., подвергают совместному помолу с небольшой, Обычно прин той в цементном производстве, добавкой гиГ1са или хлористого кальци .the requirements of the practice of massive reinforced concrete hydraulic engineering, which consists in the fact that the mixture consisting of Portland cement clinker in the amount of 40-60%, acid hydraulically additive or blast furnace granulating slag in the amount of 13-20% and 20-47% solid inert Rocks, such as: quartz sand, marshalite, solid limestone, etc., are co-milled with a small, usually adopted in cement production, the addition of gig1ca or calcium chloride.
Активные и неактивные добавки могут быть введены В состав цемента и бетона различными способами, и поэтому примен емые компоненты можно подвергнуть отдельному помолу , после чего их нужно механически тщательно перемешать.Active and inactive additives can be introduced into the composition of cement and concrete in various ways, and therefore the components used can be subjected to separate grinding, after which they must be mechanically thoroughly mixed.
В з.ви:симост от условий производства , можно сначала приготовить смесь из любых двух компонентов , а затем третий компонент ввести в вИДе водной суспензии.In Z.VI: Simost on production conditions, you can first prepare a mixture of any two components, and then enter the third component in the form of an aqueous suspension.
Основна иде , использованна при раз работке способа получени гидротехничеокого цемента, заключаетс в том, что цемент этот должен по веем своим свойствам отвечать специальныМ и общестроительным требовани м массивных гидроThe main idea used in the development of a method for producing hydraulic engineering cement is that this cement should, in accordance with its properties, meet the special and general construction requirements of massive hydroelectric cement.
