Ibikoresho bya tekinike ya Basalt Fibre yaciwe imirongo ya beto

IRIBURIRO RY'IBICURUZWA

Beto, nkibikoresho byubwubatsi bikoreshwa cyane mubwubatsi bwa gisivili, bifite imiterere yubukanishi, ariko hamwe nogukomeza kwiyongera kwimikoreshereze yubuhanga bwubuhanga, ibitagenda neza mubintu byibanze byubukorikori bigenda bigaragara buhoro buhoro. Bitewe nimbaraga nke zingirakamaro ziranga kimwe cya cumi cyimbaraga zo kwikuramo, bikavamo abanyamuryango ba tensile bakunze gucika, bigabanya mu buryo butaziguye uburebure bwibigize, bikagabanya urugero rwo gushyira mubikorwa Ibikoresho bya betos. Kunoza imikorere yubuhanga buranga ibintu bifatika no gukemura ibibazo mugukoresha beto, intiti zagiye zitezimbere imikorere yaibikoresho bifatika kumyaka myinshi kandi yageze kubisubizo byintambwe -cyiciro, nko kongeramo ibivanze, guhindura igipimo cyo kuvanga, kunoza imikorere nuburyo bwo kubungabunga.

1. Ibikoresho byo kwipimisha nuburyo bwo kwipimisha

P. O 42.5 sima isanzwe ya silikatike yatoranijwe, ifite 28d yo kwikuramo imbaraga za 48.3MPa na 28d flexural imbaraga za 8.2MPa. umucanga wo hagati ufite modulus nziza ya 2.5-2.6 yakoreshejwe nkigiteranyo cyiza, hamwe nubucucike bugaragara bwa 1996kg / m3. gukomeza kumenagura ibuye ryajanjaguwe rya 5-27mm ryakoreshejwe nkigiteranyo cyuzuye, hamwe n'ubucucike bugaragara bwa 2737kg / m3. Ikigereranyo cyo kugabanya amazi cya 40% cyakoreshejwe. 40% ya aside ya Sika polycarboxylic yakoreshejwe cyane kugabanya amazi. Uburebure bwa basalt fibre yaciwe imirongo ni nka 30mm, diameter ya monofilament igera kuri 15um, ubucucike ni 2.7g / cm3, modulus ya elastique ni 95-120MPa, imbaraga zingana ni 3300-4500MPa, naho kurambura kuruhuka ni 2,5-30.%.

Ibyangombwa bifatika bikoreshwa muri iki kizamini byerekanwe mu mbonerahamwe ya 1. Ikizamini cyo kwikuramo gishyirwa mu bikorwa hakurikijwe ibipimo ngenderwaho byuburyo bwo gukanika imiterere ya beto isanzwe. Ikizamini cyo kwikuramo gikoresha 100 × 100 × 100mm kubigero kibic, ingero 3 muri buri tsinda, gukiza bisanzwe 28d.

2. T.ni intambwe

(1) banza uhanagure igice cyikizamini kugirango gipimwe nyuma yo kugenzura isura no gupima ingano, neza kuri njye. Ubusumbane bwubuso bwikigereranyo bugera kuri 100mm, ikosa ntirirenza 0.5mm, kandi ubuso bwikurikiranya hamwe no kudahuza perpendicularity ntibigomba kuba birenze ibisabwa kurwego rwa dogere 1;

. Fungura imashini yikizamini, mugihe isahani yo hejuru-isahani hamwe nigice cyikizamini gifunze, hindura inkunga, kugirango imbaraga zibe imwe;

(3) uburyo bwo gupakira kugirango bukomeze kandi bumwe, umuvuduko wo gupakira utwara 12kN / s-18kN / s; (4) andika umutwaro ntarengwa, wuzuye kuri 0.1MPa.

3. Ibisubizo by'ibizamini no gusesengura

Nkuko bigaragara ku mbonerahamwe ya 2, 7d compressive imbaraga za beto hamwe no kwiyongera kwa Basalt fibre irerekana ibiranga idahindutse kugabanuka gahoro gahoro, biterwa ahanini no kongeramo fibre ya basalt, muri fibre na sima byakozwe mumbere kugirango bitange ubuso budakomeye, kandi hamwe no kwiyongera kwa fibre ivanze, ubu bwoko bwintege nke bukomeje kwiyongera, bityo imbaraga zo kwikuramo cubic mubisanzwe bikomeza kugabanuka. Imbaraga za 28d zo gukanda za beto hamwe no kwiyongera kwa dosiye ya basalt fibre yerekana inzira yo kwiyongera kwambere hanyuma kugabanuka, impamvu yo kwiyongera kwambere ni umubare muto wa dopedfibre gira uruhare muguhuza kurwego runaka mukugabanya kugabanuka kwimiterere ya beto ubwayo, mugihe kimwe, byongera ubuso bwintege nke ugereranije nimbaraga za 28d kwiyongera kugirango bibe bike cyane, ibyo mubikorwa rusange byimbaraga ziyongera.

4. Ibisubizo

Urebye kubububasha bwo kwikuramo imbaraga, mugihe ihuzabikorwa rya basalt fibre ivanze igera kuri 1-1.5% kubijyanye nijanisha ryijwi, imbaraga za 7d na 28 cubic compressive imbaraga za shortcut fibre beto yongerewe kurwego runaka ugereranije nu beto idafite fibre ivanze.
