1. Ibikubiye mu ngingo n'aho ishyirwa mu bikorwa riherereye
Ubu buryo bugaragaza igikoresho n'intambwe z'imikorere kugira ngo hamenyekane uko sima ya sima ikora.
Ubu buryo bukoreshwa mu kugena uko sima ya Portland imeze nk'ivu ry'ibirunga, sima ya Portland ivanze, sima isanzwe ya Portland ivanze n'ivu ry'ibirunga, sima ya Portland ivanze n'ibindi bintu byagenewe gukoresha ubu buryo.
2. Amahame ngenderwaho
Uburyo bwo gupima imbaraga za sima ya GB177
Umucanga usanzwe wa GB178 wo gupima imbaraga za sima
Icyitegererezo gisanzwe cya JBW 01-1-1 ku bijyanye n'uko sima ya sima igenda itemba
3. Uburyo bwo kumenya uburyo amazi agabanuka mu gipimo cya mortiweri ni ubu bukurikira:
3.1 Ibikoresho n'ibikoresho
A. Imvange y'ibumba;
B. Ameza yo gusimbuka (hagomba kongerwaho isahani y'ikirahure ifite ubugari bwa mm 5);
C. Udupira two gufunga icyuma: dukozwe mu byuma, dufite umurambararo wa mm 20, uburebure bwa mm 185;
D. Ifu y'urukiramende rwaciwe n'igipfundikizo cy'ibumba: Ingano y'ifu y'urukiramende rwaciwe n'igipfundikizo cy'ibumba, uburebure ni 60±0.5mm, umurambararo wo hejuru φ 70±0.5mm, umurambararo wo hasi 100±0.5mm, igipfundikizo cy'ibumba kigomba guhuzwa n'ifu y'urukiramende rwaciwe n'igipfundikizo cy'ibumba, ifu y'urukiramende rwaciwe n'igipfundikizo cy'ibumba cyakozwe mu byuma;
E. Umugenga (urugero rwo gupima rwa mm 300) cyangwa calipers zifite urugero rwo gupima rwa mm 300;
F. icyuma gishyushya.
G. Ingano y'imiti (ipima garama 1000, ipima garama 1).
3.2. Uburyo bwo gupima
3.2.1 Gupima ikoreshwa ry'amazi ya mortiweri
A. Pima garama 300 za sima na garama 750 z'umucanga usanzwe hanyuma ubisuke mu isafuriya yo kuvanga, tangira kuvanga, ongeramo amazi buhoro buhoro nyuma yo kuvanga mu gihe cy'amasegonda 5, hanyuma ubishyiremo mu gihe cy'amasegonda 30. Hagarika kuvanga mu gihe cy'iminota 3 nyuma yo gutangira imashini. Kuraho imashini ku byuma hanyuma ukureho isafuriya yo kuvanga.
B. Mu kuvanga sima icyarimwe, ukoresheje igitambaro gitose, shyiramo agatambaro ko ku meza, fata inkoni yo gukamura, gabanya ifu izunguruka hanyuma upfuke urukuta rw'imbere rw'ikirahure, hanyuma ubishyire hagati mu kirahure, upfukishe igitambaro gitose.
C. Urusenda ruvanze rugabanywamo ibice bibiri byihuse mu ibumba, urwego rwa mbere rushyirwa ku ibumba ry’ibumba rifite uburebure bwa bibiri bya gatatu, aho inkingi yo gufunga kuva ku nkengero kugeza hagati ishyirwamo inshuro cumi n’eshanu, hanyuma ishyirwamo urwego rwa kabiri rw’ibumba, rushyirwamo santimetero ebyiri hejuru y’ibumba ry’uruziga, inkoni imwe y’umuzenguruko igakora inshuro cumi n’eshanu. Mu gihe ushyira umucanga no gufunga, kanda agakoresho k’ibumba gafata umusenyi n’intoki kugira ngo wirinde kugenda.
D. Nyuma yo gukanda, kuramo igipfundikizo cy'ibumba, koresha agapira ko gukata ibumba rinini kurusha ibumba rigufi hanyuma uhanagure neza, hanyuma uzamure buhoro buhoro ibumba rizunguruka rihagaze hejuru. Huza intoki n'umugozi w'uruziga kugira ngo ameza asimbuke inshuro mirongo itatu ku muvuduko wa rimwe mu isegonda.
E. Nyuma yo gukubita, koresha calipers kugira ngo upime umurambararo w'amazi yo hasi ya mortical, kandi ufate agaciro mpuzandengo ka diameter ebyiri zigororotse nk'uko mortical ikwirakwira iyo amazi akoreshejwe, agaragazwa muri mm. Iyo mortical reference diffusivity ari 140±5mm, amazi akoreshwa ni uko mortical reference diffusivity ikoreshwa.
3.2.2 Dukurikije uburyo bwa 3.2.1, ikoreshwa ry'amazi ya mortiweri hamwe n'ikintu kigabanya amazi ryageze kuri mm 140±5.
3.3. Igipimo cyo kugabanya amazi cya mortiweri yavuwe kibarwa ku buryo bukurikira:
Igipimo cyo kugabanya amazi cya mortiweri (%) = (W0-W1) / W0 ×100
Aho, w0 — amazi akoreshwa (g) iyo ikwirakwizwa rya mortiweri y’icyitegererezo ari 140±5mm;
W1 — Ikoreshwa ry'amazi (g) iyo ikwirakwizwa rya mortiweri hamwe n'ikintu kigabanya amazi ari 140±5mm.
Agaciro k'igipimo cyo kugabanya amazi ni agaciro k'ikigereranyo cy'ibipimo bitatu.
