Description
Введение в цементные строительные растворы мокрой присадки- шлама иылевидных и гидравлических добавок известно.Introduction to cement mortars wet additives - sludge and slush and hydraulic additives is well known.
Согласно изобретению предлагаетс шлам подвергать предварительной обработке разного рода электролитами, вызывающими коагул цию ультрамикроскопически.х частиц добавок и вследствие этого измен ющими гранулометрический состав последних. В результате такой обработки при смешении шлама добавок с цементом раствора i бетона улучшаетс гранулометрический состав в целом.According to the invention, sludge is proposed to be pretreated with various kinds of electrolytes that cause the coagulation of ultramicroscopic particles of additives and, as a result, alter the granulometric composition of the latter. As a result of this treatment, by mixing the sludge additives with the cement of the concrete solution i, the particle size distribution as a whole is improved.
Наиболее простой и доступный электролит - гашена известь, которую ввод т в шлам в любом виде в небольшом количестве (от 0,5 до 2%). Оптимальное количество электролита устанавливаетс предварительным экспериментом дл каждого отдельного случа .The simplest and most accessible electrolyte is slaked lime, which is introduced into the slurry in any form in a small amount (from 0.5 to 2%). The optimum amount of electrolyte is established by preliminary experiment for each individual case.
В отличие от обычной мокрой присадки добавок к бетону и растворам предлагаемый способ дает существенное изменение подвижности бето1шой массы и растворов и позвол ет снизить в них значение водоцементногс фактора без ущерба дл их удобообрабатываемости и удобоукладываемости . Это позвол ет устранить перерасход пуццоланового портландцемента и других двух-и трехкомпонентных цементов в бетоне, вызываемый большой водопотребностью дл прида1и бетону и раствору той же подвижности , как и в случа х применени обычного портланд-цемента.Unlike conventional wet additives for concrete and mortars, the proposed method significantly changes the mobility of concrete mass and mortars and makes it possible to reduce the value of water-cement factor in them without affecting their workability and workability. This eliminates the overrun of pozzolan Portland cement and other two- and three-component cements in concrete, caused by high water demand to give concrete and a solution of the same mobility as in the case of using ordinary Portland cement.
