Concrete additives makemikari uye zvinhu zvakasanganiswa mu simenti kuti ichinje kushanda kwayo. Zviwedzerwa zvinopa bhenefiti chaiyo kune rimwe basa. Liquid additives inoshandiswa panguva yekukuya simende inovandudza simba resimende. Concrete bonding additive bonds yekare kongiri kune itsva yemukati nekunze mabasa semadziro capping uye resurfacing. Mavara ekuwedzera anopa kongiri kutaridzika kwakanaka. Chero basa ripi, kongiri zvinowedzera zvinobatsira kuti zviitwe.

Cold weather concrete ine zvimiro zvepamusoro kune kongiri inoiswa munzvimbo inopisa. Pakudziya kwakadzika, kunyange zvakadaro, kongiri inogadzika uye inowana simba zvishoma nezvishoma nokuti simenti haina hydrate nekukurumidza. Kuisa nguva inowedzerwa chinenge chikamu chimwe muzvitatu kune yega yega 10 dhigirii kuderera kwekongiri tembiricha kusvika ku40 madhigirii Fahrenheit. Kumhanyisa admixtures kunogona kubatsira kudzikamisa izvi zvinokonzeresa tembiricha yakaderera pakuseta uye kuwana simba. Ivo vanofanirwa kusangana nezvinodiwa zveASTM C 494, Yakajairwa Madiro eChemical Admixtures yeConcrete.

Jufu inopa kongiri yekuwedzera kune inotonhora mamiriro ekunze uye kongiri yekuwedzera yekudzivirira mvura, iyo inogona kushandiswa zvakanyanya muKuvaka.

Kuvaka Makemikari

Ndezvipi zvakanakira fine aggregate kongiri

1. Sezvo zvinhu zvakadaro zvine compactness yakanaka uye zvakanyanya kugadzikana panguva yekuvaka, kubudirira kwekugadzira kunovandudzwa zvikuru. Chinokosha ndechekuti usadedera mukugadzira, izvo zvinoderedza nguva yekudira uye kusimba kwebasa, uye zvakare kuderedza mutengo wevashandi.

2. Sezvambotaurwa, nokuti hapana chikonzero chekudengenyeka, hapana ruzha, uye maoko evanhu anogona kusununguka, izvo zvinonyanya kuvandudza kuchengetedzwa kwebasa uye kuvandudza mamiriro ekushanda.

3. Kubva pakuona kwehutano hwekuvaka, hapazovi nemabhubhu panzvimbo yekuvaka paunenge uchishandisa chinhu ichi, rega kugadzirisa. Panguva imwecheteyo, chiyero chayo chekusununguka chakanyanya kukwirira, kunyangwe mamwe maumbirwo akaomarara kana zvimiro zvine dense reinforcement zvinogona kudururwa nyore.

Ndedzipi dziviriro dzekusanganisa kongiri:

1. Musanganisi wekusanganiswa akashongedzerwa pasi pemamiriro akasiyana-siyana ezvinyorwa zvakasiyana, kwete izvozvo chete, asiwo zvinoenderana nemhando yezvigadzirwa zvakananga, kuitira kuti usarudze zvinhu zvakakodzera uye zvigadzirwa.

2. Kushandiswa kwechiteshi chimwe chete kana zviteshi zviviri zvinoenderana nebasa chairo. Kana yakawanda yekrete inoda kudururwa panguva imwe chete uye zvinodiwa zvehutano hwayo zvakanyanyisa, zviri nani kushandisa seti mbiri yemiti miduku yekusanganisa.
