\u201eNa nemenovanej stavbe, ktor\u00fa som svojho \u010dasu dozoroval, do\u0161lo k\u00a0z\u00e1mene triedy bet\u00f3nu vplyvom chybnej verb\u00e1lnej objedn\u00e1vky. Zistil som to pri kontrole dodacieho listu od \u0161of\u00e9ra domie\u0161ava\u010da. Beton\u00e1\u017e som ihne\u010f zastavil a prizval som si hlavn\u00e9ho stavbyved\u00faceho. Zistili sme, \u017ee sa stala verb\u00e1lna chyba pri objedn\u00e1van\u00ed bet\u00f3nu. Zamestnanec stavebnej firmy telefonicky objedn\u00e1val a\u00a0\u017eiadal tak\u00fd ist\u00fd bet\u00f3n ako naposledy. Len\u017ee nevedel, \u017ee naposledy jeho kolega objedn\u00e1val pre in\u00fa stavbu bet\u00f3n slab\u0161ej triedy. Do\u0161lo ku komunika\u010dnej chybe,\u201c vysvet\u013euje \u0160\u00e1riczki, ktor\u00fd dozoroval napr\u00edklad aj rekon\u0161trukciu ko\u0161ick\u00e9ho Kulturparku pred 13 rokmi v\u00a0r\u00e1mci EHMK. <\/p>\n

\u010do by sa stalo, ak by v\u00a0stavbe ostal slab\u0161\u00ed bet\u00f3n.<\/p>\n

Pod\u013ea medializovan\u00fdch inform\u00e1ci\u00ed m\u00e1 by\u0165 probl\u00e9mov\u00e9 prv\u00e9 nadzemn\u00e9 podla\u017eie, ktor\u00e9 vraj nie je postaven\u00e9 z\u00a0bet\u00f3nu s\u00a0pevnos\u0165ou 60 megalpascalov (MPa), ako malo by\u0165, ale z\u00a0bet\u00f3nu s\u00a0pevnos\u0165ou 30 MPa. Ak\u00fd je medzi nimi rozdiel? Je bet\u00f3n s\u00a0pevnos\u0165ou 60MPa dvojn\u00e1sobne pevnej\u0161\u00ed?<\/p>\n

Hodnota v\u00a0megapascaloch vyjadruje z\u00e1kladn\u00fa charakteristiku pevnosti bet\u00f3nu. Medzi triedou pevnosti 60 a\u00a030 s\u00fa e\u0161te \u0161tyri \u010fal\u0161ie triedy, a\u00a0to 37, 45, 50 a\u00a055 MPa.

Ak je preuk\u00e1zan\u00e9, \u017ee sa stala t\u00e1to chyba pri stavbe nemocnice, je to ve\u013emi zl\u00e9, preto\u017ee dan\u00fd kon\u0161truk\u010dn\u00fd prvok nesp\u013a\u0148a z\u00e1kladn\u00e9 podmienky statickej stability, a\u00a0t\u00fdm p\u00e1dom je kvalita stavby neakceptovate\u013en\u00e1.<\/p>\n

Je to dobr\u00fd a\u00a0kvalitn\u00fd bet\u00f3n, ktor\u00fd sa pou\u017e\u00edva do stien a\u00a0stropn\u00fdch dosiek pokia\u013e statik vyhodnot\u00ed, \u017ee je vhodn\u00fd pre za\u0165a\u017eenie konkr\u00e9tnej kon\u0161trukcie.

Bet\u00f3n s\u00a0pevnos\u0165ou 30MPa sa pou\u017e\u00edva na menej za\u0165a\u017eovan\u00e9 prvky ako bet\u00f3n s\u00a0pevnos\u0165ou 60MPa, samozrejme. Ned\u00e1 sa univerz\u00e1lne poveda\u0165, \u017ee men\u0161ie stavby si vy\u017eaduj\u00fa slab\u0161ie bet\u00f3ny a\u00a0v\u00e4\u010d\u0161ie stavby silnej\u0161ie bet\u00f3ny.
