Kev Tshawb Fawb Hauv Kev Tshawb Fawb Txog Frost Resistance ntawm Basalt Fiber Concrete, Txhim Kho Lub Tsev Ua Haujlwm nyob rau thaj tsam txias Northern
Tsis ntev los no, cov kev kawm tseem ceeb tau ua nyob rau hauv kev tshawb fawb txog Frost tsis kam ntawm basalt fiber ntau pob zeb. Cov kev tshawb fawb tau pom tias kev sib koom ua ke basalt fiber ntau tuaj yeem txhim kho qhov Frost tsis kam ntawm pob zeb, muab cov kev daws teeb meem tshiab los daws qhov kev puas tsuaj ntawm Cov Khoom Siv Ua Haujlwm tshwm sim los ntawm khov-thaw cycles nyob rau hauv txias qaum teb cheeb tsam ntawm Tuam Tshoj.
Nyob rau hauv cheeb tsam txias heev ntawm sab qaum teb Tuam Tshoj, khov-thaw cycles yog ib qho tseem ceeb ua rau pob zeb tsim deterioration. Kev puas tsuaj rau pob zeb ua los ntawm khov thiab thawing tau dhau los ua hnyav zuj zus txhua xyoo, ua rau kev tshawb fawb txog kev tiv thaiv kev tiv thaiv ntawm cov pob zeb tseem ceeb heev. Basalt Fiber ntau, vim nws cov khoom zoo heev, tau dhau los ua cov khoom tseem ceeb rau kev txhim kho Frost tsis kam ntawm pob zeb.
Tam sim no, kev tshawb fawb feem ntau suav nrog kev ntsuas lub voj voog khov-thaw los ntsuas qhov ntsuas tsis zoo xws li cov txheeb ze dynamic elastic modulus, huab hwm coj poob, compressive zog, thiab flexural zog ntawm basalt fiber ntau pob zeb, tshawb xyuas nws cov Frost tsis kam. Cov txiaj ntsig tseem ceeb suav nrog:
-
Tus txheeb ze Dynamic Elastic Modulus: Kev koom ua ke ntawm basalt fiber ntau tuaj yeem txo qis tus nqi qis ntawm tus txheeb ze dynamic elastic modulus ntawm pob zeb, nrog cov ntsiab lus fiber ntau uas ua rau qeeb qeeb.
-
Compressive Strength thiab Flexural Strength: Qhov ntxiv ntawm basalt fiber ntau tuaj yeem txo qis tus nqi ntawm compressive thiab flexural zog, nrog rau qhov zoo tshaj plaws los tiv thaiv khov nyhuv pom ntawm fiber ntau ntawm 0.15% ~ 0.20%.
-
Synergistic nyhuv nrog Cua-Entraining Agents: Basalt fiber ntau ua kom pom kev sib raug zoo nrog cov neeg ua haujlwm hauv huab cua, thiab qhov sib ntxiv ntawm cov neeg ua haujlwm huab cua tuaj yeem txhim kho cov Frost tsis kam ntawm cov pob zeb.
Txawm hais tias cov kev tshawb fawb uas twb muaj lawm tau lees paub qhov zoo ntawm cov basalt fiber ntau ntawm cov te tiv thaiv ntawm cov pob zeb, cov kev tshawb fawb tam sim no feem ntau tsom rau cov khoom siv kho tshuab tom qab lub voj voog khov-thaw, nrog rau kev tshawb fawb tsis txaus ntawm Frost resistance mechanism thiab lwm yam khoom. Tsis tas li ntawd, cov xwm txheej uas tau txiav txim siab hauv kev sim yog qhov txwv. Cov kev tshawb fawb yav tom ntej yuav tsum tau ua tib zoo xav txog ntau yam xws li tus naj npawb ntawm cov voj voog khov-thaw, ib puag ncig cov av noo, thiab ntsev tov concentration kom zoo dua ntsuas qhov Frost tsis kam. basalt fiber ntau pob zeb.
Cov kws tshaj lij qhia tias kev tshawb fawb ntawm basalt fiber ntau pob zeb muab kev txhawb nqa tseem ceeb rau kev txhim kho kev ua haujlwm ntev ntawm lub tsev cov qauv hauv cov cheeb tsam txias sab qaum teb. Nws yuav tsum tau siv dav hauv kev lag luam xws li txuas hniav, txoj kev, thiab hydraulic engineering yav tom ntej.
