Ruvara rwegranite uye kusarudzwa kwematombo ekushandisa michina yekugadzirwa kwemaindasitiri.

Muminda yekuvaka nemaindasitiri, granite inoshandiswa zvakanyanya nekuda kwekuoma kwayo, kuwanda kwayo, kuramba acid nealkali, uye kuramba mamiriro ekunze. Izvi zvinotevera ongororo yakadzama yekuti ruvara rwegranite runokanganisa here kuwanda kwayo uye kuti ungasarudza sei granite yakasimba mumunda wemidziyo yemagetsi.
Hukama huripo pakati peruvara nehuremu hwegranite
Granite inonyanya kuumbwa nezvicherwa zvakaita se quartz, feldspar ne mica, uye ruvara rwayo runoenderana nemhando uye huwandu hwezvinhu zviri mairi. Kubva pamaonero ehuwandu, pane hukama hwakati pakati peruvara nehuremu, asi haisi hukama hwakananga hwechikonzero.

 

Kusiyana kwehuwandu hwezvicherwa: Ruvara rwakajeka granite, yakaita segrey-white uye flesh-red, inowanzova ne quartz ne feldspar. Maminerari maviri aya ane huwandu hwakanyanya uye hwakagadzikana. Huwandu hwe quartz hunotangira pa 2.6 kusvika 2.7g/cm³, nepo hwe feldspar hunosiyana kubva pa 2.5 kusvika 2.8g/cm³ zvichienderana nerudzi rwayo. Kuwanda kwemaminerari akadaro kunotungamira mukuwedzera kwehuwandu hwe granite ine ruvara rwakajeka. Granite yakasviba, yakaita sedema negirini, inowanzova nehuwandu hwakawanda hwe iron ne magnesium minerals pamwe chete nemaminerari akasviba akadai se amphibole ne biotite. Huwandu hwe amphibole hunenge 3.0-3.4g /cm³, uye hwe biotite hunenge 2.7-3.1g /cm³. Zvisinei, kana granite yakasviba iine zvimwe zvinhu zvesimbi zvinorema (senge iron ne manganese), huwandu hwayo huchawedzera.

 

Mwero wekugadzika kwekristaro uye simba remaumbirwo: Dzimwe nguva ruvara runogona kuratidza mutsauko uripo pakati pehuwandu hwekugadzika kwekristaro uye maumbirwo egranite. Granite ine mwero wekugadzika kwekristaro uye maumbirwo akakora ine ruvara rwakafanana uye rwakagadzikana, uye huwandu hwayo hwakakwirawo. Izvi zvinodaro nekuti zvicherwa zvakarongwa zvakanaka uye zvine huremu hwakakura pahuwandu hweyuniti. Granite ine mwero wekugadzika kwekristaro uye maumbirwo akareruka inogona kunge iine mavara asina kujeka uye asina kuenzana, maburi mazhinji emukati, uye huwandu hwakaderera.
Kusarudzwa kwegranite mumunda wezvishandiso zvemaindasitiri zvakarurama
Muminda yemidziyo yekugadzirwa nemazvo, zvinodiwa pakugadzikana kwegranite zvakanyanya. Kazhinji, granite yakakodzera inosarudzwa nekufunga zvinhu zvakawanda:

Kuumbwa kwemaminerari uye chimiro: Granite ine huwandu hwakawanda uye kupararira kwakafanana kwequartz nefeldspar ndiyo inosarudzwa. Rudzi urwu rwegranite rune chimiro chakasimba chemukati, chinogona kuderedza zvinobudirira kukanganiswa kunokonzerwa nekuchinja kwekumanikidzwa kwemukati uye kuve nechokwadi chekushanda kwakasimba kwenguva refu kwemidziyo. Panguva iyi, granite ine mwero wekristaro, zvidimbu zvidiki uye zvakafanana, uye chimiro chakakora ndiyo sarudzo inosarudzwa. Munguva yekushandiswa kwenguva refu uye kushandiswa kwesimba, inogona kuchengetedza kururama zviri nani uye kuderedza kukanganisa kwekuchinja kwayo pakururama kwemidziyo.

Zviratidzo zvekushanda: Granite inofanirwa kuve ne mwero wakaderera wekupinza mvura, kazhinji pasi pe0.5%, kudzivirira matambudziko akadai sekuwedzera kwehuwandu uye kudzikiswa kwesimba rinokonzerwa nekupinza mvura, izvo zvinogona kukanganisa kururama kwemidziyo. Kuwedzerwa kwekupisa kunofanirwa kunge kwakaderera. Zvakanaka, inofanira kunge iri pasi pe8×10⁻⁶/℃ kuderedza shanduko dzehukuru hunokonzerwa nekushanduka kwetembiricha. Pamusoro pezvo, simba rekumanikidza rinofanira kunge rakakwira, kazhinji kupfuura 150MPa, kuve nechokwadi chekuti inogona kutsungirira masimba akasiyana-siyana panguva yekushanda kwemidziyo.
Mhando dzinokurudzirwa dzinonzi: Jinan Green Granite, Indian Black, South African Black nedzimwe granite nhema, dzine ruvara rwakasviba, dzakakora, dzine mwero wakaderera wekuwedzera kwekupisa uye dzinoramba kupfeka zvakanaka, uye dzakakodzera mabhesi emidziyo yekutarisa yemaziso ine zvinodiwa zvakanyanya kuti ive chaiyo uye yakagadzikana. Granite chena yeSesame, ine ruvara rwakajeka, zvidimbu zvemineral zvakafanana, uye kuomarara uye simba rakawanda, inoshandiswa zvakanyanya mumidziyo yekugadzira machipisi emagetsi uye inogona kusangana nezvinodiwa zvekuisa zvinhu nemazvo uye kushanda kwenguva refu kwemidziyo.

Mukupedzisa, kunyangwe paine hukama hwakati pakati peruvara nehuremu hwegranite, pakusarudza granite mumunda wemidziyo yekugadzirwa kwemagetsi, zvakakosha kufunga zvakawanda zvakaita sekuumbwa kwemaminerari, chimiro, uye hunhu hwemuviri kuti uve nechokwadi chekuti michina yacho yakanyatsogadzirwa uye yakagadzikana.
