Ndinofanira Kushandisa Mutengo Wakavhenganiswa Soro S?
Kupa simba rakakura rekumanikidzika , kupfuura 1800 psi, uye nepamusoro-soro yakasimba simba, musanganisi wemhando yemhando S ndicho chigadzirwa chakanakisisa chinofanira kushandiswa mumasoni kana pasi pegorosi. Iyo inoita zvakanyatsonaka kurwisa ivhu revhu, mhepo kana pasi pemamiriro ezvinhu emhepo. Izvi zvinogona kushandiswa kune zvidzidzo pasi pegorosi, somuenzaniso, nheyo dzemadziro, masvingo, kuchengetedza masvingo, kushambidza kwemvura, uye brick patios uye prick pavements. Nyora S s mortars inofanirwa kuva neusingasviki 1800 psi, uye mikana yavo inowanzopa simba pakati pe 2300 kusvika 3000 psi.
Nzira Yokushandisa Rudzi R Mortar?
Tora M mortar mix ine yepamusoro yePortland cement uye inokurudzirwa kutakura mitoro, masonry pasi pegorosi, nheyo, kuchengeta masvingo uye driveways. Mhando inosanganiswa yemhando M ichagovera inenge 2 500 pounds pamasendimita inch compressive power.
Chimiro M mortar nemasimba ayo akakwirira asi kusakoshesa kuisa nekuisa chisimbiso kunogona kuva sarudzo yakaipa kune imwe nzvimbo yebasa uye izvo zvinodiwa mune imwe. Tora M inoshandiswa nerombo nokuti simba redu rinomiririra iyo yedombo iri kushandiswa.
Mari yeMarara: ASTM Zvido
Masonry matope anotsanangurwa neASTM C 270, Tsanangudzo yeMatari yeChikwata Chekuita. Matope anoongororwa neASTM C 780, Kuongorora Kwekugadzirwa Kwekutanga uye Kwekuvaka kweMarara kune Chikwata Chekuita. Kutevera musangano weASTM inowanzodiwa simba rekumanikidzika yemhando imwe yemhando ndeyokuti:
