Iterambere mubwishingizi Bwiza bwa Pavement ya beto kuvanga ukoresheje petrography na licorescence microscope

Iterambere rishya muburyo bwiza bwa kaburimbo ya beto irashobora gutanga amakuru yingenzi yerekeye ubuziranenge, kuramba, no kubahiriza kode ya Hybrid.
Kubaka pavement ya beto birashobora kubona ibyihutirwa, kandi rwiyemezamirimo agomba kugenzura ubuziranenge no kuramba by'agatangwa. Ibi birori birimo guhura n'imvura mugihe cyo gusuka, gukurikiza ibikorwa byo gukiza, kugabanuka kwa plastike no guhangayikishwa namasaha make nyuma yo gusuka, no gukiza ibintu bitanga. Nubwo imbaraga zimbaraga hamwe nibindi bizamini byujujwe, injeniyeri birashobora gusaba gukuraho no gusimbuza ibice bya pavement kuko bihangayikishije niba ibikoresho byujuje ubuziranenge.
Muri iki kibazo, petrography nubundi buryo bwuzuzanya (ariko bwumwuga) burashobora gutanga amakuru yingenzi yerekeye ubuziranenge nubwiza bwivanga hamwe no kuba bahuye nibisobanuro byakazi.
Igishushanyo 1. Ingero za Microscope Microscope Micrographs ya beto kuri 0.40 W / C (hejuru yibumoso) na 0.60 w / c (hejuru iburyo). Igishushanyo mbonera cyibumoso cyerekana igikoresho cyo gupima kurwanya silinderi ya beto. Igishusho cyo hepfo iburyo cyerekana isano iri hagati yo kurwanya ingano na w / c. Chunumyo Qiao na Drp, isosiyete iganisha
Amategeko ya Aburamu yagize ati: "Imbaraga zo kunyerera zo kuvanga tarangwa na beto biragereranywa mu kigereranyo cy'ahantu h'amazi."
Porofeseri Duff BibAm yasobanuye bwa mbere isano iri hagati ya Ratio-c) n'imbaraga zitera ku mategeko ya Aburamu. " Usibye kugenzura imbaraga zo kwikuramo, igipimo cya sima y'amazi (w / cm) ubu gitoneshwa kuko kizimya gusimbuza sima ryakozwe na sima ryinyongera hamwe nibikoresho byinyongera byo kugurisha imisoro nko kuguruka. Nubuntu bwingenzi bwibintu bya beto. Ubushakashatsi bwinshi bwerekanye ko imvange zifatika hamwe na w / cm iri munsi ~ 0.45 ziraramba mubidukikije, nkibice byerekanwe na Freeze-Thew-Thaw Amazi meza cyangwa ahantu hirengeye muri SULFATE mu butaka.
Capillary Pores nigice cyihariye cyo gucika intege. Bagizwe n'umwanya uri hagati ya sima y'ibicuruzwa n'ibicuruzwa bya sima bidahwitse byahoze byuzuye amazi. ' Iyo insanganyamatsiko ya capillary ihujwe, amazi ava mubidukikije arashobora kwimuka binyuze kuri paste. Iyi ngingo yitwa kwinjira kandi igomba kugabanywa kugirango iramba. Ibikorwa bya imvange irambye ni uko eres ari igizwe aho guhuzwa. Ibi bibaho iyo w / cm munsi ya ~ 0.45.
Nubwo bigoye kugorana gupima neza w / cm ya beto akomeye, uburyo bwizewe burashobora gutanga igikoresho cyingirakamaro mu buryo bwo gukora iperereza ku kibanza cyacitse. Microscopy Microscopy itanga igisubizo. Nuburyo bukora.
Microsconce Microscopy ni tekinike ikoresha epoxy resin na fluorescent dyes kugirango imurikiremo ibisobanuro birambuye. Bikoreshwa cyane mubumenyi bwubuvuzi, kandi bifite kandi porogaramu zingenzi muri siyanse. Gahunda ya sisitemu yuburyo muri beto yatangiye hashize hafi imyaka 40 i Danemark [3]; Byari bisanzwe mu bihugu bya Nordic mu 1991 cyo kugereranya w / c ya beto akomeye, kandi yavuguruwe mu 1999 [4].
Gupima w / cm ibikoresho bishingiye kuri sima (ni ukuvuga nyirarume, minisiteri, hamwe na epoxy Inzira ikubiyemo inkoni ya beto cyangwa silinderi yaciwe ahantu nyaburanga (bita ubusa) hamwe nubuso bwa mm hafi 25 x 50 (1 x 2). Ubusa bwahagaze ku kirahure, gishyirwa mu cyumba cya vacuum, kandi epoxy resin yatangijwe munsi ya vacuum. Nkuko w / cm yiyongera, guhuza hamwe numubare wimbuto biziyongera, epoxy cyane izinjira muri paste. Dusuzuma urumuri munsi ya microscope, dukoresheje urutonde rwihariye rwo kuyungurura kugirango dushimishe doyes fluorescent muri epoxcent muri epoxy resin no kuyungurura ibimenyetso birenga. Muri aya mashusho, ahantu h'ibirabura byerekana ibipimo biterankunga hamwe na sima idahwitse. Uburozi bwa bibiri ni 0%. Icyatsi kibisi ni uburozi (ntabwo ari poroity), kandi poroity ni 100%. Kimwe muribi biranga icyatsi kibisi "ibintu" ni paste (Ishusho 2). Nka w / cm na capillary porotity yiyongereyeho beto, ibara ryicyatsi ryinshi rya paste rihinduka cyane kandi ryiza (reba Ishusho 3).
Igishushanyo cya 2. Micrographcence ya Flack yerekana ibice biterabwoba, amadozi (v) hanyuma wa Paste. Ubugari bwa Horizontal ni ~ 1.5 mm. Chunumyo Qiao na Drp, isosiyete iganisha
Igishushanyo cya 3. Micrographs za Micrograph zerekana ko uko W / Cm yiyongera, paste yicyatsi gahoro gahoro. Izi mvugo zirateshutse kandi zirimo kuguruka. Chunumyo Qiao na Drp, isosiyete iganisha
Isesengura ryishusho ririmo gukuramo amakuru menshi mumashusho. Ikoreshwa mubice byinshi bya siyansi, kuva kure yunvise microscope. Buri pigiseli mumashusho ya digitale ihinduka mubyukuri amakuru. Ubu buryo butwemerera guhuza imibare ku nzego zinyuranye zinyuranye zigaragara muri aya mashusho. Mu myaka 20 ishize cyangwa irenga, hamwe na mpinduramatwara mu mbaruka yo kubara na digitale, isesengura ry'ishusho rimaze guhinduka igikoresho gifatika (harimo na peteroli intobe nyinshi (harimo na peteroli zifatika) zishobora gukoresha. Dukunze gukoresha isesengura ryamashusho kugirango dupime umuhigo wa capillary yo gucibwa. Nyuma yigihe, twasanze hariho ibanga ryibarurishamibare rikomeye rihuza w / cm hamwe nuburozi bwa capillary, nkuko bigaragara mu ishusho ikurikira (Ishusho ya 4 n'Ishusho 5).
Igishushanyo cya 4. Urugero rwamakuru rwakuwe muri micrografiya ya fluorescence yibice bitoroshye. Iyi plaque yitegura umubare wa pigiseli kurwego rwahawe imvi zahawe amafoto amwe. Impinga eshatu zihuye na comgretrike (umurongo wa orange), paste (agace keza), nijwi ryuzuye (impinga zuzuye (impinga zuzuye iburyo). Umurongo wa paste wemerera imwe kubara ingano ya pore hamwe nibisanzwe. Chunu qiao na Driao, ingeso yisosiyete 5. Iyi ndama yo muri make urukurikirane rwa w / cm 95% mu ruvange ruvanze, isazi ivu ririnde. Chunumyo Qiao na Drp, isosiyete iganisha
Mu isesengura rya nyuma, ibizamini bitatu byigenga birasabwa kwerekana ko kuri beto kurubuga yubahiriza uburyo bwo kuvanga. Kubishoboka, shaka ibyingenzi byingenzi bivuye mubikorwa byujuje ibisabwa byose byemejwe, kimwe ningero ziva mubikorwa bifitanye isano. Ikositimu kuva kumiterere yemewe irashobora gukoreshwa nkicyitegererezo, kandi urashobora kuyikoresha nkibyenswa kugirango usuzume imiterere yimiterere ijyanye.
Mubyatubayeho, mugihe ba injeniyeri zifite inyandiko zibona amakuru yakuwe muri ibi bizamini, bakunze kwemera gushyira niba ibindi bintu byingenzi byubuhanga (nko kwikuramo imbaraga) byujujwe. Mugutanga ibipimo bifatika bya W / CM hamwe nibikorwa byo gushinga, turashobora kurenga ibizamini byerekanwe kumirimo myinshi kugirango tugaragaze ko imvange ivugwa ifite imiterere nziza.
David Rothstein, Ph.d., PG, fagiti ni umutware mukuru wa DRP, isosiyete iganisha. Afite imyaka irenga 25 ya petrologue umaze uburambe, kandi kugiti cye yashinjwa inshuro zirenga 10,000 kuva mumishinga irenga 2000 kwisi yose. Dr. Chunu qiao, umuhanga mu bya siyansi ya DrP, isosiyete iganishaho, ni geologiya n'ibikoresho umuhanga mu bihe birenga icumi mu bikoresho byo guhamya no gutunganya ibidukikije kandi bitunganijwe. Ubuhanga bwe burimo gukoresha isesengura ryishusho na microscopy yo kwiga iramba rya beto, hibandwa cyane kubyangiritse biterwa n'ubwinyungo, Alkali-Silicon
