Imiterere ya tekiniki ya Basalt Fiber strips scated beto

INTANGIRIRO Y'IBICURUZWA

Beto, nk'ibikoresho by'ubwubatsi bikoreshwa cyane mu bwubatsi bw'ubwubatsi, ifite imiterere myiza ya mekanike, ariko uko ikoranabuhanga ry'ubwubatsi rikomeza kwiyongera, inenge z'imiterere yayo y'ibanze ya mekanike zigenda zigaragara buhoro buhoro. Bitewe n'imbaraga nke zo gukurura za kimwe cya cumi cy'imbaraga zo gukanda, bituma ibice bigize inzira yo gukanda bikunze kwangirika, ibyo bigabanura mu buryo butaziguye kuramba kw'ibice, bigagabanya uburyo bwo gukoresha Ibikoresho bya betos. Kugira ngo kunoze imikorere ya sima mu buhanga no gukemura ibibazo byo gukoresha sima, intiti zagiye zinoza imikorere yaibikoresho bya sima imyaka myinshi kandi byageze ku musaruro ku cyiciro, nko kongeramo ibivange, guhindura igipimo cyo kuvanga, kunoza uburyo bwo gukora n'uburyo bwo kubungabunga.

1. Ibikoresho byo gupima n'uburyo bwo gupima

P. O 42.5 sima isanzwe ya silicate yatoranijwe, ifite imbaraga zo gukanda za 28d za 48.3MPa n'imbaraga zo gukanda za 28d za 8.2MPa. Umucanga uringaniye ufite modulus nziza ya 2.5-2.6 wakoreshejwe nk'umusemburo muto, ufite ubucucike bugaragara bwa 1996kg/m3. Ibuye ryasenyutse rihoraho rya 5-27mm ryakoreshejwe nk'umusemburo muto, ufite ubucucike bugaragara bwa 2737kg/m3. Hakoreshejwe igipimo cyo kugabanya amazi cya 40%. Hakoreshejwe 40% bya aside polycarboxylic ya Sika igabanya amazi neza cyane. Uburebure bwa udutsi twaciwemo fibre ya basalt ni nka mm 30, umurambararo wa monofilament ni hafi 15um, ubucucike ni 2.7g/cm3, modulus yo gushisha ni 95-120MPa, imbaraga zo gukurura ni 3300-4500MPa, kandi uburebure mu gihe cyo kuruhuka ni hafi 2.5-30%.

Ibipimo byakoreshejwe muri iki kizamini bigaragazwa mu mbonerahamwe ya 1. Ikizamini cyo gukanda gishyirwa mu bikorwa hakurikijwe Standard for Test Methods of Mechanical Properties of Ordinary Beton. Ikizamini cyo gukanda gikoresha ingero za kibe 100 × 100 × 100 mm, ingero 3 muri buri tsinda, ingero zisanzwe zo gukanda 28d.

2. Tni intambwe

(1) banza uhanagure igice cy'igerageza kigomba gupimwa nyuma yo gusuzuma uko gisa no gupima ingano, neza kuri njye. Ubusumbane bw'ubuso bw'ingero bugera kuri mm 100, ikosa ntirirenze mm 0.5, kandi ubuso bw'ingero n'ubudahangarwa bw'aho biri ntibigomba kurenza ibisabwa by'urugero rwa dogere 1;

(2) umurongo w'icyitegererezo cy'imashini igerageza uhujwe n'igice cyo hagati cy'icyuma gipima munsi y'imashini igerageza. Fungura imashini igerageza, iyo igice cyo hejuru cy'igipimo n'igice cy'igerageza bifunze, hindura inkingi, ku buryo imbaraga ziba zimwe;

(3) uburyo bwo gupakira bugumana uburyo buhoraho kandi bungana, umuvuduko wo gupakira ikizamini ungana na 12kN / s-18kN / s; (4) kwandika umutwaro ntarengwa, utarenze 0.1MPa.

3. Ibisubizo by'ibizamini n'isesengura

Nkuko bigaragara ku mbonerahamwe ya 2, imbaraga zo gukanda za sima za 7d hamwe n'ubwiyongere bwa Basalt Imigozi igaragaza imiterere y’uko idahinduka ikagabanuka buhoro buhoro, ahanini biterwa no kongeramo imigozi ya basalt, mu migozi na sima byakozwe aho bihurira kugira ngo bikore ubuso butoroshye, kandi uko ingano y’imigozi ivangwa, ubwo bwoko bw’ubuso buto bukomeza kwiyongera, bityo imbaraga zo gukanda za cubic zikomeza kugabanuka mu buryo busanzwe. Ingufu zo gukanda za sima za 28d hamwe n’ubwiyongere bw’ingano ya basalt zigaragaza icyerekezo cyo kwiyongera bwa mbere hanyuma kikagabanuka, impamvu y’ubwiyongere bwa mbere ni ingano nto ya dopedinsinga za basalt bigira uruhare mu guhuza ku rugero runaka mu kugabanya guhindagurika kwa sima ubwayo, mu gihe kimwe byongera ubuso butoshye ugereranyije n’ubwiyongere bw’imbaraga bwa 28d bukaba buke cyane, ibyo bikaba mu mikorere rusange y’imbaraga byiyongera.

4. Ibisubizo

Ukurikije imbaraga zo gukandagira mu buryo bwa cubic, iyo imvange y'udusimba twa basalt igera kuri 1-1.5% ukurikije ingano y'ubwinshi, imbaraga zo gukandagira mu buryo bwa cubic 7d na 28 z'uburyo bwa cubic 20. fibre ya basalt beto yongerwa ku rugero runaka ugereranije n'iya beto idafite fibre ivanze.
