Изобретение относитс к технике получени пористых заполнителей дл бетонных и железобетонных изделий и может быть использовано на предпри ти х сборного железобетона и на заводах , производ щих пористые заполнители ,The invention relates to a technique for the production of porous aggregates for concrete and reinforced concrete products and can be used in precast concrete plants and plants producing porous aggregates,
Известен способ обработки вспученного перлитового песка 1 путем перемешивани в течение 1,5-2 мин с кремнеорганическим веществом.A known method of treating expanded perlite sand 1 by mixing for 1.5-2 minutes with organosilicon material.
Недостатком его вл етс пониженна прочность заполнител и низка адгези к цементу.The disadvantage of it is reduced aggregate strength and low adhesion to cement.
Наиболее близким по технической сущности и достигаемому результату вл етс способ обработки пористых заполнителей pacfBojpaMH солей 2 .The closest in technical essence and the achieved result is a method of processing porous aggregates of pacfBojpaMH salts 2.
Недостатком его вл етс пониженна прочность и адгезионна способност к цементу.The disadvantage of it is reduced strength and adhesiveness to cement.
Цель изобретени - повышение прочности , создание поверхностной кольматации пор и повышение адгезии к цементу .The purpose of the invention is to increase the strength, create surface clogging of the pores and increase adhesion to the cement.
Поставленна цель достигаетс тем, что обработку осуществл ют растворами солей, образующими с гидроокисью кальци нерастворимые соединени , в течение 5-10 с, а затем известковым молоком в течение 8-12 с.This goal is achieved in that the treatment is carried out with solutions of salts that form insoluble compounds with calcium hydroxide for 5-10 seconds, and then with lime milk for 8-12 seconds.
Причем,в качестве растворов солей образующих с гидроокисью кальци нерастворимые соединени , используют/ сульфаты, или фториды,или карбонаты,или оксалаты или тартраты щелочноземельных металлов.Moreover, as solutions of calcium hydroxide-forming salts, insoluble compounds are used / sulfates, or fluorides, or carbonates, or oxalates or tartrates of alkaline earth metals.
Пример. Подогретый до 70-80 С керамзит сначала окунают на 8 с в раствор соли с концентрацией 200 г/л, а затем на 10 с в известковое молоко. В таблице приведена прочность заполнител и сцепление его с цементным камнем .Example. Heated clay heated to 70-80 ° C is first dipped for 8 s into the salt solution with a concentration of 200 g / l, and then for 10 s into the milk of lime. The table shows the strength of the aggregate and its adhesion with the cement stone.
Дл химической кольматации пор лекого заполнител используют M(f&0t, и другие химические реактивы, образующие с гидроокисью кальци нераствориMbie соединени , например сульфаты, фториды, карбонаты, оксалаты, тартраты многих металлов. В первую очередь по экономическим соображени м представл ют интерес растворимые соли железа и магни .M (f & 0t, and other chemical reagents that form with the calcium hydroxide insoluble Mbie compounds, such as sulfates, fluorides, carbonates, oxalates, and many metal tartarates, are used for chemical clogging of the pores of the exchanger.) iron and magnesium.
