Description
Obecnie znanych jest kilka sposobów wytwarzania mas porowatych z materja¬ low mineralnych posiadajacych zdolnosc wiazania, przyczem proces ten odbywa sie przy pomocy metali, które w obecnosci wody wytwarzaja gazy.Metale uzywane dotad w tym celu ma¬ ja rózne wady, które czynia je niezdatne- mi do praktycznego uzytku. Zgóry trzeba wykluczyc takie metale, jak cynk, magnez, zelazo i t. d., które dzialaja w wyzej poda¬ ny sposób tylko przy podwyzszonej tempe* raturze, a przy temperaturze normalnej wytwarzaja gazy tylko w obecnosci alka- ljów lub pewnych chlorków, jak np. chlo¬ rek wapnia, niezaleznie od tego czy mate- rjalem alkalicznym jest w danym wypad¬ ku wapno zawarte w cemencie, czy alka- lja dodane jako specjalna domieszka. W tych warunkach zmieniaja sie skladniki ce¬ mentu, który staje sie przez to gorszy.Odpowiednim do omawianego celu móglby byc glin, który silnie rozdrobnio* ny rozklada wode przy temperaturze nor¬ malnej i byl wielokrotnie zalecany do wy* robu betonu komórkowego, lecz ma te wa* de, ze w obecnosci pewnych domieszek (np. najmniejszych sladów alkalicznych solikwasu krzemowego), wystepujacych w ce- meiicie dosc czesto- glin powleka sie war¬ stwa ochronna* niedopuszczajaca dziala¬ nia wody. Uzywajac glinu, trzeba zatem stosowac domieszki niedopuszczajace do zobojetnienia glinu (pewne sole i podobne substancje), lecz domieszki te wplywaja niekorzystnie na wlasciwosci cementu.Z innych metali, które nadawalyby sie do tego celu, wspominano juz w literatu¬ rze bar i wapn,i które reaguja z woda juz przy temperaturze zwyczajnej. Bar nie na¬ daje sie jednak dla celów praktycznych z powodu wysokiej ceny a pozatem jest przy normalnej temperaturze, równie jak wapn. tak miekki, ze nie mozna go rozdrabniac w pozadanym stopniu, a tern samem nie moz* na go równomiernie mieszac z masa.Teoretycznie idealnym srodkiem bylby wapn, bo niewielka ilosc wodorotlenku wapnia, powstajaca przy jego utlenianiu, nie wplywa szkodliwie na wlasciwosci ce* mentu.W mysl wynalazku niniejszego uzywa sie zatem wapnia, lecz w celu usuniecia jego wlasciwosci niepozadanych, wymie¬ nionych wyzej, nie stosuje sie go w stanie czystym, lecz w postaci stopów z innemi odpowiednio dobranemi metalami, jak ma¬ gnez i cynk. Stopy takie mozna bardzo do¬ kladnie proszkowac, tak ze mieszanie ich z masa nie przedstawia zadnych trudnosci.Dlugosc okresu wywiazywania gazów moz* na regulowac zmieniajac odpowiednio sto¬ sunek wagowy- skladników stopu i stopien jego rozdrobnienia. Tern samem mozna re* gulowac czas trwania szkodliwego okresu pomiedzy zakonczeniem gazowania i po* czatkiem twardnienia cementu i dostoso¬ wywac go do fakosci uzytych materjalów mineralnych.Zamiast stopów wapn-cynk i wapn- magnez mozna tez uzywac potrójnego sto* pu wapn-magnez*cynk. Zawartosc wapnia powinna wynosic od 70 do 80%, lecz na" wet stopy zawierajace o polowe mniej wapnia sa jeszcze skuteczne, jakkolwiek dzialanie ich jest mniej dokladne. PLAt present, several methods are known to produce porous masses from mineral materials having the ability to bind, but the process is carried out with metals which, in the presence of water, generate gases. me for practical use. It is necessary to exclude such metals as zinc, magnesium, iron, etc., which operate in the above-mentioned manner only at elevated temperature, and at normal temperature produce gases only in the presence of alkali or certain chlorides, such as, for example, chlorine. Calcium, irrespective of whether the alkaline material is lime contained in the cement or an alkali added as a special admixture. Under these conditions, the cement components change, which makes the cement worse. A suitable clay for the purpose in question could be clay, which decomposes water very finely at normal temperature and has been repeatedly recommended for the production of aerated concrete, but has Also, the disadvantage is that in the presence of certain impurities (eg the smallest traces of alkali silicic acid) present in the coal, quite often aluminum is coated with a protective layer which does not allow the action of water. When using aluminum, it is therefore necessary to use admixtures that prevent the neutralization of the aluminum (certain salts and similar substances), but these admixtures adversely affect the properties of the cement. Other metals that would be suitable for this purpose have already been mentioned in the literature of barium and lime, and which react with water already at ordinary temperature. However, barium is not suitable for practical purposes because of its high price, and is otherwise at normal temperature, just like lime. so soft that it cannot be crushed to the desired degree, and the same cannot be mixed evenly with the mass. Theoretically, the ideal solution would be lime, because the small amount of calcium hydroxide generated during its oxidation does not adversely affect the properties of the cement Calcium is therefore used in the context of the present invention, but in order to remove its undesirable properties, mentioned above, it is not used in its pure state, but in the form of an alloy with other appropriately selected metals, such as magnesium and zinc. Such alloys can be very finely powdered, so that mixing them with the mass does not present any difficulties. The length of the gas release period can be adjusted by changing the weight ratio of the alloy components and the degree of its fragmentation, respectively. The same can be used to regulate the duration of the harmful period between the end of the gassing and the beginning of the cement hardening and adapt it to the quality of the mineral materials used. Instead of the calcium-zinc and calcium-magnesium alloys, you can also use the triple calcium-magnesium alloy * zinc. Calcium content should be between 70 and 80%, but even alloys containing half the calcium are still effective, although their action is less accurate.
