TDR-28型混凝土快速凍融試驗節能環保型產品簡介

TDR-28型混凝土快速凍融試驗節能環保型試(shi)(shi)驗采(cai)用(yong)水(shui)凍(dong)(dong)水(shui)融(rong)(rong)(rong)法,把符合(he)外觀要(yao)(yao)求(qiu)的(de)(de)(de)(de)(de)100×100×400的(de)(de)(de)(de)(de)混(hun)凝(ning)土(tu)試(shi)(shi)件(jian)(jian)(jian)和(he)測(ce)溫試(shi)(shi)件(jian)(jian)(jian)放(fang)進試(shi)(shi)件(jian)(jian)(jian)桶中(zhong),用(yong)17～23℃的(de)(de)(de)(de)(de)水(shui)浸泡4天(tian)，然后把試(shi)(shi)件(jian)(jian)(jian)桶放(fang)入凍(dong)(dong)融(rong)(rong)(rong)試(shi)(shi)驗槽中(zhong)，用(yong)循(xun)環(huan)的(de)(de)(de)(de)(de)冷凍(dong)(dong)液對(dui)試(shi)(shi)件(jian)(jian)(jian)反(fan)復進行(xing)降(jiang)(jiang)溫和(he)升溫，周期性(xing)(xing)(xing)地把試(shi)(shi)件(jian)(jian)(jian)內放(fang)的(de)(de)(de)(de)(de)水(shui)進行(xing)凍(dong)(dong)結和(he)融(rong)(rong)(rong)化。混(hun)凝(ning)土(tu)試(shi)(shi)件(jian)(jian)(jian)每做25次(ci)凍(dong)(dong)融(rong)(rong)(rong)循(xun)環(huan)試(shi)(shi)驗，都要(yao)(yao)測(ce)量(liang)(liang)1次(ci)重(zhong)量(liang)(liang)和(he)相(xiang)(xiang)對(dui)動彈(dan)性(xing)(xing)(xing)模(mo)量(liang)(liang)。當相(xiang)(xiang)對(dui)動彈(dan)性(xing)(xing)(xing)模(mo)量(liang)(liang)下降(jiang)(jiang)至初始值的(de)(de)(de)(de)(de)60％或質(zhi)(zhi)量(liang)(liang)損失(shi)率達(da)5％時(shi)，即認為(wei)試(shi)(shi)件(jian)(jian)(jian)已達(da)破壞，并以(yi)相(xiang)(xiang)應的(de)(de)(de)(de)(de)凍(dong)(dong)融(rong)(rong)(rong)循(xun)環(huan)次(ci)數(shu)作為(wei)該(gai)混(hun)凝(ning)土(tu)的(de)(de)(de)(de)(de)抗凍(dong)(dong)等(deng)級(ji)。如果試(shi)(shi)件(jian)(jian)(jian)凍(dong)(dong)融(rong)(rong)(rong)至預定(ding)的(de)(de)(de)(de)(de)循(xun)環(huan)次(ci)數(shu)，而相(xiang)(xiang)對(dui)動彈(dan)性(xing)(xing)(xing)模(mo)量(liang)(liang)或質(zhi)(zhi)量(liang)(liang)損失(shi)率均未達(da)到(dao)上述(shu)指(zhi)標，可認為(wei)試(shi)(shi)驗的(de)(de)(de)(de)(de)混(hun)凝(ning)土(tu)抗凍(dong)(dong)性(xing)(xing)(xing)已滿足(zu)(zu)設計(ji)(ji)要(yao)(yao)求(qiu)。根據凍(dong)(dong)融(rong)(rong)(rong)循(xun)環(huan)次(ci)數(shu)及相(xiang)(xiang)應的(de)(de)(de)(de)(de)相(xiang)(xiang)對(dui)動彈(dan)性(xing)(xing)(xing)模(mo)量(liang)(liang)可計(ji)(ji)算出混(hun)凝(ning)土(tu)耐(nai)久性(xing)(xing)(xing)系數(shu)，供設計(ji)(ji)選材時(shi)參(can)考(kao)。因(yin)此(ci)，在動彈(dan)性(xing)(xing)(xing)模(mo)量(liang)(liang)，質(zhi)(zhi)量(liang)(liang)損失(shi)率和(he)耐(nai)久性(xing)(xing)(xing)系數(shu)為(wei)評定(ding)指(zhi)標的(de)(de)(de)(de)(de)混(hun)凝(ning)土(tu)抗凍(dong)(dong)試(shi)(shi)驗中(zhong)，本(ben)裝(zhuang)置是(shi)*的(de)(de)(de)(de)(de)試(shi)(shi)驗設備。可滿足(zu)(zu)國內外各(ge)相(xiang)(xiang)關行(xing)業設計(ji)(ji)、研究、施工的(de)(de)(de)(de)(de)需要(yao)(yao)。
