Description
Znany sposób wytwarzania lekkiego betonu z zawierajacej wode mieszaniny drobno sproszkowa¬ nego materialu krzemowego z glina albo cemen¬ tem portlandzkim lub innym spoiwem hydraulicz¬ nym, albo glina i spoiwem hydraulicznym, polega na dodaniu do tej mieszaniny czynnika, wytwa-1 rzajacego gaz lub piane, i poddaniu jej dzialaniu pary. W celu umozliwienia odpowiedniego doboru gestosci i skurczu mieszaniny, jak równiez regu¬ lowania przebiegu reakcji pomiedzy woda a spoi¬ wem hydraulicznym albo glina, dodaje sie do tej mieszaniny materialu, zawierajacego cukier, lub innych substancji, posiadajacych wlasciwosci cu¬ kru.Do wyrobu mieszaniny uzywa sie drobno zmie¬ lonego piasku, zwyklej nie palonej gliny, glinki kaolinowej lub innych materialów, skladajacych sie glównie z krzemianów glinu i bardzo rozdrob¬ nionych zwiazków krzemowych.Poszczególne zwiazki krzemowe róznia sie znacznie podczas dzialania pary swoja aktyw¬ noscia i w celu nadania mieszaninie dostatecznej wytrzymalosci mechanicznej nalezy przy wyrobie betonu lekkiego wybrac zwiazek, który latwo wchodzi w reakcje z zawartym w mieszaninie materialem glinowym lub cementem.Na przyklad zwiazek fluoru z kwarcem, pod¬ dany wraz z cementem portlandzkim dzialaniu pary, reaguje okolo 7 razy latwiej niz szpat pol- ' ny, a aktywnosc czystego kwarcu jest znacznie wieksza niz aktywnosc nie palonej gliny. Wytrzy¬ malosc mechaniczna wyrobu, zawierajacego pia¬ sek z glina', jest wiec mniejsza niz wytrzymalosc wyrobu, wytworzonego z czystego piasku.Sposób wedlug wynalazku opiera sie na spo¬ strzezeniu, ze przez ogrzewanie lub wypalanie aktywnosc surowców, zawierajacych gline, mozna znacznie zwiekszyc. W przypadku uzycia miesza¬ niny krzemianów glinowych z kwarcem nalezy w tym celu ogrzewac je do temperatur, stosowanych przy wypalaniu cegiel. Wytworzony w ten sposób material lub zwyczajna zmielona cegla moze za-stapic czesciowo albo calkowicie stosowany do¬ tychczas normalnie material kwarcowy. Uzycie zmielonej cegly nie obniza wytrzymalosci mecha¬ nicznej wytworzonego betonu i nie zmusza do zwiekszania cisnienia pary przy obróbce cieplnej ani nie przedluza czasu obróbki.Sposób wedlug wynalazku umozliwia uzycie wypalonej juz gliny, cegly, odpadków z cegiel oraz pylu ceglanego do wyrobu lekkiego betonu, a wobec obojetnosci obróbki cieplnej na obecnosc zaprawy murarskiej moze byc zastosowany do wyrobu lekkiego betonu z gruzu, pozostalego po zniszczonych budynkach z cegly. PLA known method of producing lightweight concrete from a water-containing mixture of finely powdered silicon material with clay or Portland cement or other hydraulic binder, or clay and hydraulic binder, consists in adding a gas or foam generating agent to the mixture. , and subjecting it to steam. In order to enable the proper selection of the density and shrinkage of the mixture, as well as to regulate the course of the reaction between the water and the hydraulic binder or clay, material containing sugar or other substances having the properties of sugar are added to the mixture. finely ground sand, plain unburned clay, kaolin clay or other materials consisting mainly of aluminum silicates and very finely divided silicon compounds are used. The various silicon compounds differ greatly in the action of steam and in order to give the mixture its effect. sufficient mechanical strength, when producing lightweight concrete, choose a compound that easily reacts with the clay material or cement contained in the mixture.For example, a compound of fluorine with quartz, given with the action of steam with Portland cement, reacts about 7 times more easily than spatula. - 'ny, and the activity of pure quartz is much greater n and with the activity of unburned clay. The mechanical strength of a product containing clay sand is thus lower than that of a product made of pure sand. The method according to the invention is based on the notion that by heating or firing the activity of raw materials containing clay, it is possible to significantly increase . If a mixture of aluminum silicates with quartz is used, it should be heated to the temperatures used in the firing of bricks. The material produced in this way, or an ordinary ground brick, can partially or completely replace the normally used quartz material. The use of ground bricks does not reduce the mechanical strength of the concrete produced and does not force the steam pressure to increase during heat treatment, nor does it extend the processing time. Due to the indifference of heat treatment to the presence of masonry, it can be used for the production of lightweight concrete from rubble, left over from dilapidated brick buildings. PL
