Chodabwitsa: Pambuyo powonjezera chochepetsera madzi, konkire siinalimba kwa nthawi yayitali, ngakhale kwa usana ndi usiku, kapena pamwamba pake imatulutsa 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 kusakanikirana 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 vuto lalikulu lakumira.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 nthunzi, 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.
