三.Non coagulation phenomenon
Chodabwitsa: Pambuyo powonjezera chochepetsera madzi, konkire siinalimba kwa nthawi yayitali, ngakhale kwa usana ndi usiku, kapena pamwamba pamakhala slurry ndikutembenukira chikasu.
Kusanthula zifukwa:
(1) Mlingo wambiri wa wochepetsera madzi;
(2) Kugwiritsa ntchito kwambiri ma retarders.
Terms of kuthetsa:
(1) Osapitirira 2-3 mlingo wovomerezeka, ngakhale kuti mphamvu yachepa pang'ono, kuchepetsa mphamvu za masiku 28 ndizochepa, ndipo kuchepetsa mphamvu kwa nthawi yaitali kumakhala kochepa;
(2) Pambuyo pokhazikitsa komaliza, moyenerera onjezani kutentha kwa machiritso ndikulimbitsa kuthirira ndi kuchiritsa;
(3) Chotsani gawo lomwe linapangidwa ndikuthiranso.
四.Chochitika chochepa kwambiri
Chodabwitsa: Mphamvu ndizochepa kwambiri kuposa zotsatira za mayeso a msinkhu womwewo, kapena ngakhale konkire yakhazikitsidwa, mphamvuyo ndi yochepa kwambiri.
Kusanthula zifukwa:
(1) Kuwonjezeredwa mochulukira kwa mpweya wopatsira madzi wochepetsera madzi kumabweretsa mpweya wochuluka mu konkire;
(2) Kugwedezeka kosakwanira mutatha kusakaniza ndi mpweya wochepetsera madzi;
(3) Kusachepetsa madzi kapena kuwonjezera chiŵerengero cha simenti ya madzi m’malo mwake;
(4) Wonjezerani kuchuluka kwa triethanol yowonjezeredwa.
Terms of kuthetsa:
(1) Kutengera njira zina zolimbikitsira kapena kuthiranso;
(2) Limbikitsani positi kugwedera;
(3) Chitanipo kanthu kuti muthetse zifukwa zomwe tafotokozazi.
五.Kutaya msanga kwa kugwa
Chodabwitsa: Konkire imasiya kugwira ntchito mwachangu, ndipo pakatha mphindi 2-3 zilizonse mutatha kutulutsidwa mu thanki, kutsika kumachepa ndi 1-50 mm, ndipo pamakhala chodabwitsa chomira pansi. High slump konkire ndi sachedwa chodabwitsa ichi.
Kusanthula zifukwa:
(1) Zochepetsera madzi sizitha kusinthika ku simenti yogwiritsidwa ntchito;
(2) The thovu anadzetsa mu konkire mosalekeza kusefukira, kuchititsa madzi evaporation, makamaka ntchito mpweya entraining madzi kuchepetsa wothandizila;
(3) Kutentha kwakukulu kosanganikirana konkire kapena kutentha kwa chilengedwe;
(4) Kutsika kwa konkire ndikokwera kwambiri.
Terms of kuthetsa:
(1) Pezani chifukwa chake ndikuchitapo kanthu kuti muthetse;
(2) Pogwiritsa ntchito njira yosakaniza positi, wochepetsera madzi amawonjezedwa 1-3 mphindi mutasakaniza konkire kapena ngakhale musanathire, kenaka musakanizenso;
(3) Samalani kuti musathire madzi.
六.Mgwirizano wokhazikika
Pambuyo kuthira, padzakhala ming'alu yaifupi, yowongoka, yotakata, komanso yosazama mu konkire isanayambe komanso itatha.
Kusanthula zifukwa:
Pambuyo powonjezera zochepetsera madzi, konkire imakhala yowoneka bwino, sichimatuluka magazi ndipo sizovuta kukhazikika kwathunthu, nthawi zambiri zimawoneka pamwamba pazitsulo zazitsulo;
Terms of kuthetsa:
Ikani kupanikizika kwa ming'alu isanayambe komanso itatha kukhazikitsidwa koyambirira kwa konkire mpaka itatha.
