1. Ibintu bikubiyemo nurwego rwo gusaba
Ubu buryo bugaragaza ibikoresho nintambwe zo gukora kugirango hamenyekane amazi ya sima.
Ubu buryo burakoreshwa mukumenya amazi ya marimari ya sima ya Portland, sima ikomatanya Portland, sima isanzwe ya Portland ivanze nivu ryibirunga, sima ya Portland sima nubundi bwoko bwa sima yagenewe gukoresha ubu buryo.
2. Ibipimo ngenderwaho
GB177 Uburyo bwo gupima imbaraga za sima
GB178 Umusenyi usanzwe wo gupima imbaraga za sima
JBW 01-1-1 Icyitegererezo gisanzwe cyamazi ya sima
3. Uburyo bwo kumenya igipimo cyo kugabanya amazi ya minisiteri nuburyo bukurikira:
3.1 Ibikoresho n'ibikoresho
A. Kuvanga Mortar;
B. Gusimbuka kumeza (isahani yikirahure 5mm igomba kongerwamo);
C. Akabari ka cilindrical: kakozwe mubikoresho byicyuma, diameter 20mm, uburebure bwa 185mm;
Д.
E. Umutegetsi (gupima intera 300mm) cyangwa kaliperi ifite uburebure bwa 300mm;
F. spatula.
G. Kuringaniza ibiyobyabwenge (bipima 1000g, kumva 1g).
3.2. Uburyo bwo gukora ibizamini
3.2.1 Gupima ikoreshwa ry'amazi ya minisiteri
A. Gupima sima 300g n'umucanga usanzwe 750g hanyuma ubisuke mu nkono ivanze, tangira kuvanga, shyiramo amazi gahoro nyuma yo kuvanga kuri 5s, hanyuma ubishyiremo muri 30. Hagarika kubyutsa 3min nyuma yo gutangira imashini. Kuraho minisiteri kuri blade hanyuma ukureho isafuriya.
B. Mu kuvanga minisiteri icyarimwe, hamwe nigitambaro gitose uhanagura ameza yo gusimbuka kumeza, inkoni ya ramming, ukata cone izengurutswe hamwe nurupapuro rutwikiriye urukuta rwimbere, hanyuma ubishyire hagati yisahani yikirahure, yuzuyeho igitambaro gitose.
C. Imvange ivanze ihita igabanywamo ibice bibiri mubibumbano, igice cya mbere gishyirwa kumurongo wa cone hafi ya bibiri bya gatatu by'uburebure, hamwe numurongo wogusimba kuva kumpande kugera hagati ugashyiramo kuringaniza inshuro cumi nagatanu, hanyuma ugashyirwa kumurongo wa kabiri wa minisiteri, ugashyirwa kuri santimetero ebyiri hejuru yububiko, inkoni imwe ya silindrike ikubita inshuro cumi n'eshanu. Mugihe urimo gupakira umucanga no gutombora, kanda cone ya troncate ipfa mukuboko kugirango wirinde kugenda.
D. Nyuma yo kuyikuramo, kuramo igifuniko, koresha spatula kugirango ukureho marimari iri hejuru yikibumbano cya cone cyaciwe hanyuma uhanagure neza, hanyuma uzamure buhoro buhoro uruziga ruzengurutse hejuru. Fata amaboko hamwe n'uruziga rw'uruziga kugirango ameza yo gusimbuka asimbuke inshuro mirongo itatu ku gipimo kimwe ku isegonda.
E. Nyuma yo gukubitwa, koresha Calipers kugirango upime ikwirakwizwa rya diameter yo hepfo ya minisiteri, hanyuma ufate impuzandengo yikigereranyo cya diametero ebyiri perpendicular kuri mugenzi wawe nkuko ikwirakwizwa rya minisiteri iyo amazi akoreshejwe, yerekanwe muri mm. Iyo minisiteri ya minisiteri ikwirakwizwa ni 140 ± 5mm, gukoresha amazi nugukoresha amazi yo gukwirakwiza minisiteri.
3.2.2 Ukurikije uburyo 3.2.1, gukoresha amazi ya minisiteri hamwe nogukoresha amazi bigera kuri 140 ± 5mm.
3.3. Igipimo cyo kugabanya amazi ya minisiteri yatunganijwe kibarwa kuburyo bukurikira:
Igipimo cyo kugabanya amazi ya minisiteri (%) = (W0-W1) / W0 × 100
Aho, w0 - gukoresha amazi (g) mugihe ikwirakwizwa rya minisiteri ari 140 ± 5mm;
W1 - Gukoresha amazi (g) mugihe ikwirakwizwa rya minisiteri igabanya amazi ni 140 ± 5mm.
Agaciro k'igabanuka ry'amazi ni imibare isobanura agaciro k'ibitegererezo bitatu.
