Description
W celu nadania warstwie betonowej, nakladanej na powierzchnie drogi, wiek¬ szej trwalosci, stosuje sie dotychczas szklo wodne, które jednak nie wsiaka do wne¬ trza warstwy, poniewaz zwykly beton nie zawiera porów, przepuszczajacych wode.Wskutek tego zwiekszenie trwalosci jezdni osiaga sie tylko na jej powierzchni, która jest równiez gladka. Jako powloke stosu¬ je sie równiez mieszanine szkla wodnego z cementem, woda i kamieniem.Warstwa betonowa, nakladana na po¬ wierzchnie drogi przy wykonywaniu jej wedlug wynalazku, sklada sie z szutru, pia¬ sku, cementu, mielonego szkla lub podob¬ nego materjalu i stosunkowo wielkiej ilo¬ sci wody. Taki beton po stwardnieniu po¬ siada otwory, przez które szklo wodne wsiaka do wnetrza warstwy.W celu nadania trwalosci betonowi mie¬ sza sie cement z mielonem szklem (mielo¬ nym kwarcem, mielona porcelana, mielo- nemi odpadkami palonego magnezytu, do¬ lomitu, wapnia), który to materjal wiaze chemicznie wolny CaO, zawarty w cemen¬ cie. Po nasiaknieciu szklem wodnem po¬ wstaje nadzwyczaj trwala warstwa z mie¬ szaniny glinianów, zelaza, wapnia i krze¬ mianów, która waze równiez chemicznie NaX), zawarty w szkle wodnem, i nadaje betonowi wielka wytrzymalosc na sciera¬ nie. Oprócz tego stwardnienie masy wyma-ga krótszego czasie a beton taki nie jest wrazliwy na dzialanie dcwasów.' W^cfelu 'otr^yma^la betonu miesza sie cem,qHt z wyzej wymieniona maczka i wo¬ da, a otrzymana zaprawe — z szutrem (gruzem, piaskiem lub podobnym jnaterja¬ lem)". Mase te ubija sie lub walcuje, a po wyschnieciu (w przyblizeniu po 24 godzi¬ nach) nasyca sie ja szklem wodnem, prze- siakajacem zupelnie warstwe.W celu zwiekszenia porowatosci beto¬ nu stosuje sie szuter lub piasek o okraglych ziarnach, jak równiez dodaje sie do beto¬ nu nieco wieksza ilosc wody, wskutek cze¬ go po zwiazaniu powstaje wieksza ilosc o- tworów. Konieczne ilosci cementu sa mniejsze, niz przy dotychczas stosowanych sposobach, poniewaz cement dodaje sie w pewnej ilosci jedynie w celu wyzyskania jego wlasciwosci hydraulicznych, a reszte cementu zastepuje sie maczka.Przyklad. Mieszanina 1,25 m3 szutru 15 x 25 mm, 100 kg maczki, 250 kg cemen¬ tu, 0,65 m3 piasku 0—6 mm, 170 1 wody na 1 m3 ubitego betonu wymaga w przyblize¬ niu 100 kg szkla wodnego o 35°Be. Zamiast pewnej czesci piasku mozna zastosowac o- pilki zelazne. PLIn order to make the concrete layer applied to the road surface more durable, water glass has hitherto been used, but it does not stick to the inside of the layer, because ordinary concrete does not contain pores that allow water to penetrate. on its surface, which is also smooth. A mixture of water glass with cement, water and stone is also used as a coating. The concrete layer applied to the road surfaces in the process according to the invention consists of gravel, sand, cement, ground glass or similar material. and relatively large amounts of water. Such concrete, after hardening, has holes through which the water glass of the plug into the interior of the layer. , calcium), which material binds chemically free CaO contained in the cement. After impregnating with water glass, an extremely durable layer of a mixture of aluminates, iron, calcium and silicates is formed, which also chemically weighs NaX), contained in the water glass, and gives the concrete a great resistance to abrasion. In addition, the mass hardening requires a shorter time and the concrete is not sensitive to acid attack. The concrete is mixed with cement, the above-mentioned flour and water, and the mortar obtained - with gravel (rubble, sand or similar jnaterial) ". The mass is compacted or rolled, and after drying (approximately after 24 hours) it is saturated with water glass, penetrating the layer completely. In order to increase the porosity of concrete, gravel or sand with round grains is used, and a slightly larger amount is added to the concrete. water, as a result of which, after setting, more holes are formed.The necessary amounts of cement are smaller than in the methods used so far, because cement is added in a certain amount only to exploit its hydraulic properties, and the rest of the cement is replaced by flour. A mixture of 1.25 m3 of 15 × 25 mm gravel, 100 kg of flour, 250 kg of cement, 0.65 m3 of sand 0-6 mm, 170 l of water per 1 m3 of compacted concrete requires approximately 100 kg of water glass with 35 ° Be. Iron nails can be used instead of some sand. PL
