Ready-mix mortar chinhu chakakosha chekuvaka chinoshandiswa mumhando dzakasiyana dzezvirongwa zvekuvaka.Musanganiswa wesimende, jecha, mvura, uye dzimwe nguva lime.Musanganiswa wakagadzirwa kuti ushandiswe kune zvidhinha, zvidhinha, uye zvimwe zvinhu zvekuvaka kuti zvisunge pamwechete.Nekudaro, kuti uwane zvakanyanya kubva pazvinhu izvi, zvinodikanwa kuwedzera makemikari ekuwedzera kuti uvandudze mashandiro, kusimba uye processability.Muchinyorwa chino, tichatarisa zvikonzero nei makemikari ekuwedzera achidikanwa mudhaka rakagadzirwa-yakasanganiswa.
1. Kuwedzera kusimba kwezvivakwa
Kugara kwechivako kunokanganiswa zvakanyanya nekusimba kwedhaka.Kuti uvandudze simba, kunamatira uye kudzivirira mvura kwedhaka, makemikari anowedzera anofanira kushandiswa.Zvimwe zvokuwedzera zvakagadzirirwa kubatsira dhaka kuti ridzivirire chando, munyu, uye kusvibiswa kwemaindasitiri izvo zvingangokuvadza dhaka nekufamba kwenguva.Kuwedzerwa kwemakemikari aya kunobatsira kuita kuti dhaka rive rakasimba, pakupedzisira rinowedzera hupenyu hwechivako.
2. Kuvandudza kushanda kwedhaka
Kushanda (workability) zvinoreva kureruka uko dhaka rinoparadzirwa, kuumbwa nekuchekwa.Makemikari anowedzera anobatsira kuvandudza kushanda uye kuenderana kwedhaka uye kuona kuti inoramba ichienderana mukati mekuita basa rekuvaka.Izvi zvinowedzera zvinobatsira kudzora mhepo yemukati, viscosity uye nguva yekuisa yedhaka, zvichiita kuti zvive nyore kune vavaki kushandisa chigadzirwa pasina kuoma.Nekuvandudza kushanda, vavaki vanogona kuwana zvirinani kupedzisa uye mhedzisiro ichave yakanaka.
3. Wedzera simba rekubatanidza
Kusimba kwechisungo chedhaka zvakare chinhu chakakosha mukugara kwechivako.Mishonga yemakemikari inowedzera kusimba kwechisungo chedhaka nekuvandudza kunamatira kwayo kune zvidhinha, zvidhinha, uye zvimwe zvekuvaka.Ichi chinhu chinoita kuti dhaka rirambe kushushikana sehuremu hwechivako, njodzi dzinongoitika dzoga kana kudengenyeka kwenyika.Kusimba kwechisungo chedhaka kunobata zvinhu zvekuvakisa zvakasimba uye zvisingachinji, kuve nechokwadi chekuti chimiro chinoramba chakagadzikana muhupenyu hwayo hwesevhisi.
4. Deredza kuderera kwedhaka
Sezvo dhaka rinooma, rinoderera zvishoma, zvichiita mikaha pakati pezvidhinha nemabhuroko echivako.Aya mapeji anogona kuva nengozi kana akasazadzwa sezvo anogona kunetesa chimiro uye kubvumira mvura kupinda mukati. Mishonga yemakemikari inoderedza kuderera kwedhaka, zvichiita kuti zvidhinha nezvinhu zvibatane zvakasimba pamwechete.Kuderedza shrinkage zvakare kunoderedza mukana wekutsemuka uye kuputika nekufamba kwenguva.Shrinkage-inoderedza dhaka inogadzira kunyange kudzvanywa kugovera, izvo zvakakosha kuti ive nechokwadi chekuti chimiro chinoramba chakagadzikana muhupenyu hwayo hwesevhisi.
5. Kuvandudza kusamira kwemamiriro ekunze
Kukwanisa kwedhaka kutsungirira mamiriro ekunze ndechimwe chinhu chinokosha pakusimba kwaro.Mamiriro ekunze ekunze akadai semhepo ine simba, kunaya kwemvura uye kunyorova kwakanyanya kunogona kukanganisa zvakanyanya kusimba kwedhaka uye pakupedzisira chivakwa.Makemikari anowedzera akagadzirirwa kubatsira dhaka kuramba aya mamiriro ekunze.Semuenzaniso, zvimwe zvinowedzera zvinogona kubatsira dhaka kusapinda mvura uye kudzivirira kunyura kwemvura, nepo zvimwe zvinogona kudzivirira dhaka kubva pakupisa kwakanyanya.Nekuwedzera kwekudzivirira kwemamiriro ekunze, dhaka rinochengetedza simba rayo uye kuvimbika kunyange mumamiriro ekunze akaoma.
6. Deredza mari yekuvaka
Makemikari ekuwedzera anogona zvakare kuderedza mitengo yekuvaka nekuvandudza zvivakwa zvedhaka uye kuderedza yakazara nguva yekuvaka.Nekuvandudza kushanda uye kuenderana kwedhaka, vavaki vanogona kushanda nekukurumidza uye zvakanyanya, vachidzikisa zvakanyanya mutengo wevashandi pamapurojekiti.Pamusoro pezvo, kuderedzwa kuderera uye kuvandudzwa kwesimba rezvisungo zvinobatsira kudzivirira kugadzirisa zvinodhura uye kugadzirisa mune ramangwana.Nekudzikisa mutengo wekuvaka, makemikari ekuwedzera anopa mhinduro inokwanisika kuti ive nechokwadi chekugara kwezvivakwa.
Kuwedzerwa kwemakemikari ekuwedzera kune yakagadzirira-yakasanganiswa dhaka kwakakosha pakusimba uye kuita kwechivako chako.Makemikari anowedzera anowedzera simba, kunamatira, kushanda uye kuramba kwemamiriro ekunze kwedhaka, kuderedza shrinkage uye pakupedzisira kuve nechokwadi chehupenyu hurefu hwechimiro.Iko kushandiswa kwezvinowedzera kunobatsirawo kuderedza mari yekuvaka uye kuwedzera aesthetics yese yechivakwa.Naizvozvo, makemikari ekuwedzera anodiwa mumatope akagadzirira-akavhenganiswa kuti awane yakakwirira-mhando, yakasimba, uye yakanaka zvimiro.
