Description
Легкие искусственные заполнители дл бетона в том виде, в каком, они обычно примен ютс , имеют р д недостатков.Lightweight artificial aggregates for concrete, as they are commonly used, have a number of disadvantages.
Коте, и доменные вспл чеиные шлаки («термозит), керамзитовый П1,ебе11ь и , облада си.чьно развитой поверхностью и раковистой структурой, образуют е иементиым тестом ма.Ю пластичную бетонную смесь. Поэтому получение достаточно удобообрабатываемоГ массы св зано с больншм перерасходом в жущих.Kote, and blast furnace slag (“thermal deposit”), expanded clay P1, fume and, having a highly developed surface and a shell structure, form the cement concrete mixture with its own dough. Therefore, the production of a sufficiently workable mass is associated with the over-expenditure in the population.
Кроме того, поверхность перечисленных заполнителей представл ет собой сеть открытых пор, что, в свою очередь. вызывает лишний расход цемента и создает новьниенную водопс1моп1аемость заполнителей , ухудша качество изделий.In addition, the surface of the listed aggregates is a network of open pores, which in turn. causes extra cement consumption and creates new water consumption of aggregates, worsening the quality of products.
ОписываелизШ способ производства заполиителей дл бетона дает возможность изготовл ть легкие заполнители , . лишенные указанных недостатков.The method of producing fillers for concrete allows for the manufacture of lightweight aggregates,. deprived of these disadvantages.
Сущность и особенность иредлагаемого способа заключаетс в том, что в процессе изготовлени легких заполнителей в период их остывани , после термической оораоотки, в интервале тет шератур от 400 до 250 их в, водным раствором барды сульфит-целлюлозных щелоков. Благодар образоваппю при указанных тепшературах полимеров лигносульфоновых кислот и пропсход щему одноБрег 1енно процессу ,1еин к дупнр 1они1 ripn: receii в барде, на частицах пористого заполнител образхетс тонкий слой полимеров. Наличие этого сло .сохран ющегос благодар адсорбционным сила.м и в из:мельченном продукте, звеличивает пластичность бетонной смеси, что дает возможность уменьшить расход в л-сущего вещества па 10 - 15 i .The essence and peculiarity of the proposed method lies in the fact that in the process of manufacturing lightweight aggregates during their cooling, after thermal heating, in the range of tetrature from 400 to 250 of them, with an aqueous solution of bards of sulfite-cellulose liquors. Due to the formation of a lignosulphonic acid polymers and a single process that is heated, 1 ein to the 1n1 ripn: receii in bard, a thin layer of polymers forms on the porous filler particles. The presence of this layer, which is conserved because of the adsorption forces and in the: ground product, makes the concrete mixture plasticize, which makes it possible to reduce the consumption of n-substance pa 10 - 15 i.
Вместе с тем, некоторое уменьиюние ,1иофильиости зано.мннте.г уменылает водспоглсн1С и;е бегска и иовышает его долговечность.At the same time, a certain decrease in the volume of filthiness of zo.mnnte.g reduces water consumption and its efficiency and increases its durability.
Барда разбавл етс водой в соотношении 1:5 (но весу). Получаемый раствор слунчит дл увлажнени заполнител из расчета 150 л указанного раствора на 1 г занолиите .т . Это соответствует примерно 0,25j сухого вешества лигиосульфоновых полимеров по весу в жущего в бетонной смеси.The bard is diluted with water in a 1: 5 ratio (but by weight). The resulting solution will be used to moisten the aggregate at the rate of 150 liters of this solution per 1 g of zonolitol. T. This corresponds to approximately 0.25j of dry weight of the polyosulfonic polymers by weight permeating in the concrete mix.
