Vst\u00fapte do hry s odpenova\u010dom bet\u00f3nu - t\u00edto chlapci s\u00fa ako tabletka na schladenie va\u0161ej bet\u00f3novej zmesi. S\u00fa to chemik\u00e1lie, ktor\u00e9 odstra\u0148uj\u00fa otravn\u00e9 vzduchov\u00e9 bubliny a zabezpe\u010duj\u00fa, \u017ee v\u00e1\u0161 bet\u00f3n bude siln\u00fd, hladk\u00fd a pripraven\u00fd vydr\u017ea\u0165. S bet\u00f3nov\u00fdmi vecami sa zaober\u00e1m u\u017e roky a poviem v\u00e1m, \u017ee ke\u010f si raz osvoj\u00edte odpe\u0148ova\u010de, budete sa \u010dudova\u0165, ako ste mohli stava\u0165 bez nich.<\/p>\n
\u010co presne je odpenova\u010d bet\u00f3nu? Predstavte si to takto: ke\u010f \u0161\u013eah\u00e1te bet\u00f3n, m\u00e1te cement, vodu, piesok, \u0161trk a mo\u017eno aj nejak\u00e9 pr\u00edsady. Pri mie\u0161an\u00ed a pumpovan\u00ed sa do zmesi dost\u00e1va vzduch, ktor\u00fd vytv\u00e1ra penu. Pena nie je len ne\u0161kodn\u00e9 \u0161umenie; oslabuje bet\u00f3n t\u00fdm, \u017ee v \u0148om vznikaj\u00fa dutiny, ktor\u00e9 m\u00f4\u017eu nesk\u00f4r praskn\u00fa\u0165 alebo do\u0148 prenikn\u00fa\u0165 voda. Odpe\u0148ova\u010d je v podstate povrchovo akt\u00edvna l\u00e1tka alebo zmes zl\u00fa\u010den\u00edn, ktor\u00e9 pri kontakte s bet\u00f3nom tieto bubliny rozb\u00edjaj\u00fa. Je to ako prida\u0165 kvapku mydla na riad do mastnej vody - puf, pena sa rozpadne. V\u00e4\u010d\u0161ina odpenova\u010dov je tekut\u00e1, \u013eahko sa do nej naleje a p\u00f4sob\u00ed r\u00fdchlo bez toho, aby naru\u0161ila ostatn\u00e9 vlastnosti bet\u00f3nu.<\/p>\n
Na\u010do sa s t\u00fdm tr\u00e1pi\u0165? Po prv\u00e9, v\u00fdrazne zvy\u0161uje silu. Bez dodato\u010dn\u00fdch vzduchov\u00fdch vreciek m\u00f4\u017ee v\u00e1\u0161 bet\u00f3n dosiahnu\u0165 vy\u0161\u0161iu pevnos\u0165 v tlaku - v niektor\u00fdch pr\u00edpadoch hovor\u00edme a\u017e o 20-30% vy\u0161\u0161ej pevnosti. To znamen\u00e1 menej opr\u00e1v v bud\u00facnosti, \u010do v\u00e1m u\u0161etr\u00ed peniaze a bolesti hlavy. Okrem toho poskytuje vynikaj\u00faci povrch. Videli ste niekedy na doske tie \u0161kared\u00e9 dierky alebo drsn\u00e9 povrchy? Odpe\u0148ova\u010de ich vyhladia, tak\u017ee bud\u00fa vyzera\u0165 ako profesion\u00e1lne. A pre \u013eud\u00ed v stavebn\u00edctve je to zmena v oblasti \u010derpate\u013enosti. Spenen\u00e1 zmes upch\u00e1va \u010derpadl\u00e1 a hadice ako nikto in\u00fd, ale s odpenova\u010dom te\u010die ako po masle. A \u010do sa t\u00fdka \u017eivotn\u00e9ho prostredia? Niektor\u00e9 modern\u00e9 s\u00fa ekologick\u00e9, s n\u00edzkym obsahom prchav\u00fdch organick\u00fdch l\u00e1tok, tak\u017ee v\u0161ade nevyp\u00fa\u0161\u0165ate nepr\u00edjemn\u00e9 chemik\u00e1lie.<\/p>\n
Ako tieto veci vlastne funguj\u00fa? Je to trochu vedeck\u00e9, ale nie raketov\u00e1 veda. Penidlo sa rozprestiera na povrchu penov\u00fdch bubl\u00edn, \u010d\u00edm zni\u017euje povrchov\u00e9 nap\u00e4tie. To sp\u00f4sob\u00ed, \u017ee bubliny praskn\u00fa alebo sa spoja do v\u00e4\u010d\u0161\u00edch, ktor\u00e9 \u013eah\u0161ie unikn\u00fa. Predstavte si to, ako ke\u010f rob\u00edte diery do bal\u00f3nikov - vzduch jednoducho vylet\u00ed von. K\u013e\u00fa\u010dom je na\u010dasovanie: prid\u00e1vate ho po\u010das mie\u0161ania, zvy\u010dajne po po\u010diato\u010dnom zmie\u0161an\u00ed, aby neinterferoval s in\u00fdmi pr\u00edmesami, ako s\u00fa superplastifik\u00e1tory. Ak je jej pr\u00edli\u0161 ve\u013ea, m\u00f4\u017ee d\u00f4js\u0165 k nadmern\u00e9mu napeneniu a strate spracovate\u013enosti; ak je jej pr\u00edli\u0161 m\u00e1lo, pena sa dr\u017e\u00ed na mieste. Profesion\u00e1li ho zvy\u010dajne d\u00e1vkuj\u00fa v mno\u017estve 0,1% a\u017e 1% pod\u013ea hmotnosti cementu, ale v\u017edy si najprv skontrolujte etiketu alebo vysk\u00fa\u0161ajte mal\u00fa d\u00e1vku.<\/p>\n
Existuje nieko\u013eko typov v z\u00e1vislosti od toho, s \u010d\u00edm sa zaober\u00e1te. Odpe\u0148ova\u010de na b\u00e1ze silik\u00f3nu s\u00fa ve\u013emi popul\u00e1rne, preto\u017ee s\u00fa \u00fa\u010dinn\u00e9 vo vysoko alkalickom prostred\u00ed, ako je bet\u00f3n. Maj\u00fa dlh\u00fa \u017eivotnos\u0165 a dobre sa vyrovn\u00e1vaj\u00fa s teplom, \u010do je ide\u00e1lne na zalievanie v hor\u00facom po\u010das\u00ed. Potom m\u00e1te nesilik\u00f3nov\u00e9, napr\u00edklad na b\u00e1ze miner\u00e1lneho oleja alebo alkoholu, ktor\u00e9 s\u00fa lacnej\u0161ie a skvel\u00e9 v pr\u00edpadoch, ke\u010f by silik\u00f3ny mohli sp\u00f4sobi\u0165 \u0161kvrny alebo probl\u00e9my s kompatibilitou. Existuj\u00fa aj pr\u00e1\u0161kov\u00e9 odpe\u0148ova\u010de, ktor\u00e9 s\u00fa vhodn\u00e9 na such\u00e9 zmesi alebo prefabrik\u00e1ty. Ak sa zauj\u00edmate o ekologick\u00fa v\u00fdstavbu, h\u013eadajte mo\u017enosti na biologickej b\u00e1ze z rastlinn\u00fdch olejov - tie sa ujali, preto\u017ee s\u00fa udr\u017eate\u013en\u00e9 a neohrozuj\u00fa v\u00fdkon.<\/p>\n
V re\u00e1lnom svete sa tieto odpe\u0148ova\u010de objavuj\u00fa v\u0161ade. Vezmite si napr\u00edklad beton\u00e1rne: denne vy\u010derpaj\u00fa tony bet\u00f3nu a odpenova\u010de udr\u017euj\u00fa n\u00e1kladn\u00e9 aut\u00e1 v pohybe bez zdr\u017eania. Pri ve\u013ek\u00fdch projektoch, ako s\u00fa mosty alebo v\u00fd\u0161kov\u00e9 budovy, kde je potrebn\u00e9 bet\u00f3n dokonale rozvibrova\u0165 a skonsolidova\u0165, odpe\u0148ova\u010de zabezpe\u010duj\u00fa, aby nedo\u0161lo k zachyteniu vzduchu, ktor\u00fd by oslabil kon\u0161trukciu. Dokonca aj pri samonivela\u010dn\u00fdch podlah\u00e1ch alebo dekorat\u00edvnom bet\u00f3ne zabra\u0148uj\u00fa t\u00fdm bublinkov\u00fdm nedokonalostiam, ktor\u00e9 kazia estetick\u00fd dojem. Spom\u00ednam si, ako som pom\u00e1hal kamar\u00e1tovi s podlahou v gar\u00e1\u017ei - bez odpe\u0148ova\u010da vyzerala ako \u0161vaj\u010diarsky syr. Pridal som kvapku a bum, bol zrkadlovo hladk\u00fd.<\/p>\n
Ale hej, nie je to v\u0161etko slne\u010dn\u00e9. Mus\u00edte ich spr\u00e1vne pou\u017e\u00edva\u0165. Pred\u00e1vkovanie m\u00f4\u017ee sp\u00f4sobi\u0165, \u017ee zmes bude pr\u00edli\u0161 hust\u00e1 a \u0165a\u017eko sa bude umiest\u0148ova\u0165, alebo dokonca sp\u00f4sob\u00ed odde\u013eovanie. V\u017edy ju jemne premie\u0161ajte, aby ste sa vyhli vytv\u00e1raniu v\u00e4\u010d\u0161ej peny ironicky. A skladujte ich spr\u00e1vne - mimo dosahu mrazu alebo extr\u00e9mneho tepla, inak by sa mohli oddeli\u0165 a strati\u0165 \u00fa\u010dinnos\u0165. Ak ste v tomto smere nov\u00e1\u010dik, za\u010dnite s odpor\u00fa\u010daniami v\u00fdrobcu alebo sa porozpr\u00e1vajte s dod\u00e1vate\u013eom; maj\u00fa zasv\u00e4ten\u00e9 tipy.<\/p>\n
Celkovo mo\u017eno nie je odpenova\u010d bet\u00f3nu najbizarnej\u0161\u00edm n\u00e1strojom v k\u00f4lni, ale je nevyhnutn\u00fd pre ka\u017ed\u00e9ho, kto to mysl\u00ed v\u00e1\u017ene so stavbou, ktor\u00e1 vydr\u017e\u00ed sk\u00fa\u0161ku \u010dasom. Nabud\u00face, ke\u010f budete ma\u0165 na kolen\u00e1ch vyliate bet\u00f3ny, vysk\u00fa\u0161ajte ich - v\u00e1\u0161 chrb\u00e1t (a pe\u0148a\u017eenka) v\u00e1m po\u010fakuj\u00fa. Kto by povedal, \u017ee rozb\u00edjanie bubl\u00edn m\u00f4\u017ee by\u0165 tak\u00e9 d\u00f4le\u017eit\u00e9? Stavajte \u010falej, priatelia!<\/p>\n
