Przedmiot wynalazku niniejszego sta¬ nowi sposób wyrobu cementu z zuzli i in¬ nych zwiazków krzemiankowych w postaci naturalnej lub odpadków róznych fabryka- cyj.Znane sa liczne sposoby otrzymywania cementu przez oddzialywanie wzajemne wapna oraz materjalów zawieraijacych w swym skladzie kwas krzemowy i w tym ce¬ lu szczególnie czesto stosuje 'sie zuzle wielkopiecowe. Zawsze jednak wychodzo¬ no dotychczas z zalozenia, ze w gotowym cemencie pod wplywem wilgoci musi zajsc miedzy skladnikami kwasnetmi i zaisadowe- mi czyli miedzy krzemianami i wapnem wymiana (reakcja wzajemna), aby gotowy cement zyskal nalezyta trwalosc.Proponowano przeto mielenie ziarni¬ stych zuzli wielkopiecowyh wraz z wapnem gaszcnem, przyczem stosowano otrzymy¬ wane droga granulacji zuzle z pewna za¬ wartoscia wody, gdyz z jednej strony oba¬ wiano sie wysychania ziaren (zuzli), z dru¬ giej zas strony wychodzono z zalozenia, ze domieszane wapno zrace z woda pochodza¬ ca z zuzli wytwarza pewna ilosc cieplika, który wywiera wplyw na zwiazki krzemo¬ we i nadaje mieszaninie wlasciwosci ce¬ mentu. Stosowano równiez odciaganie wo¬ dy zapomoca wapna w celu suszenia pro¬ duktu ziarnistego. Posunieto sie jeszcze dalej w tym kierunku, uwazano bowiem za korzystne dodawanie po zmieleniu do mie¬ szaniny ziarnistej masy oraz wapna wodyw znaczniejszych nawet ilosciach w wypad¬ kach, gdy masa rzeczona stracila jej zbyt wiele, wskutek dluzszego lezenia.Pokazuje sie jednak, ze mozna wytwo¬ rzyc cement wysokogatunkowy i dajacy sie przechowywac przez okresy czasu nader dlugie z wysuszonych w zupelnosci zuzli - wielkopiecowych lulb mater jalowi innych, równiez obfitujacych w zwiazki kwasu krzemowego (jako to inne zuzle hutnicze, kamien kotlowy lub martwica, tras i podob¬ ne miaterjaly), mielac je nadizwycziaj mialko z wapnem palonem niegaszoinem. Pokazalo sie, ze trwalosc na przechowywanie mate- rjalu zalezy w silnym stopniu od braku wodzianu wapnia w mieszaninie. Mozna równiez zemlec oddzielnie czesci skladowe i nastepnie zmieszac; korzystniejsze jest jednak mielenie wspólne Wszystkich czesci skladowych.Zamiast wapna zracego o wyzszej lub nizszej procentowosci mozna równiez sto¬ sowac i wapno hydrauliczne, o ile jednak nie zawiera ono krzemianów. Samo sie przez sie rozumie, ze do cementu mozna, jak zwykle, dodac przy mieleniu od 1 do 5% gipsu.Cecha istotna wynalazku jest warunek, aby czesci skladowe cementu zarówno kwa¬ sne jak i zasadowe byly (w znaczeniu tech- nicznem) pozbawione wody, PLThe subject of the present invention is a method of producing cement from waste and other silicate compounds in the natural form or waste from various factories. There are many methods of obtaining cement by the interaction of lime and materials containing silicic acid, and for this purpose. bad blast furnaces are particularly often used. Until now, however, it has always been assumed that in the finished cement, under the influence of moisture, there must be an exchange between the acid and base components, i.e. between the silicates and the lime (mutual reaction), so that the finished cement gains its proper stability. of blast furnaces together with slak lime, while the obtained granulation method was used poorly with a certain water content, because on the one hand, the grains (slags) were both supposed to dry out, and on the other hand, it was assumed that the mixed lime would the water from the mold produces a certain amount of heat, which affects the silicon compounds and gives the mixture cement properties. Draining of the water with lime was also used to dry the granular product. Even more significant amounts of water were added in this direction, since it was considered advantageous to add water after grinding to the mixture of granular mass and lime, even in cases where the mass in question had lost too much of it as a result of prolonged resting. to produce a high-quality cement that can be stored for very long periods of time from completely dried slags - blast furnace or material to others, also rich in silicic acid compounds (such as other bad smelting stone, boiler stone or necrosis, trass and similar materials ), by grinding them, add the flour to the ground with non-smoked lime. It has been shown that the storage stability of the material is highly dependent on the absence of calcium hydrate in the mixture. You can also grind the components separately and then mix them; However, it is preferable to grind all the components together. Instead of a higher or a lower percentage of roughened lime, hydraulic lime can also be used, provided it does not contain silicate. It goes without saying that the cement may, as usual, be mixed with 1% to 5% of gypsum during grinding. An essential feature of the invention is that the cement components, both acidic and alkaline, are (technically) free from water, PL
