Simende-jecha dhaka masonry zvidhina

Zvatinosiita mhinduro kuti rokuvaka simende-jecha mhando iri zvinoberekwa nokusanganisa mbiri huru zvinoriumba: jecha uye simende. Zvikuru mhinduro nokuti rokuvaka vari yemanyorero 1: 4 RESHIYO kana 1: 6. Chinangwa chipi mhinduro iri kurambidza misha paakapa zvidhinha kune mumwe. Naizvozvo, kuitwa nokuisa zvidhinha kuvaka zvakagadzirwa chete kaviri compressive mutoro uye misha. Ndokusaka ichi kuti mhinduro mhando dzakaondoroka. Mune zvimwe zviitiko, zvakadai mhinduro inogona kuwedzerwa nevhu kana madota, izvi zvimwe zvinoriumba kubvumira kupa mhinduro ine plasticity uye flowability. Mune zvisingawanzoitiki nguva zvinogona kushandiswa pachinzvimbo kwesuko Washing upfu kana sipo. Asi kana achiisa zvidhina , zvakadai musanganiswa dzichayerera kunyika yose iripo cheap car insurance pakati pezvitina, iyo ine kunambwa ayo chafariz insulating ehupfumi.

A mhinduro yakagadzirirwa nokuisa zvidhinha nyore: nokusanganisa dzinokosha zvokubikisa (ejecha jecha) rakaoma chimiro uye mune unozotevera vaiitawo pamberi kushandiswa nemvura. Zvinofanira pakarepo akagadzira shoma mhinduro (varumbidzwa vhoriyamu 25-30 litres). Asi kana pezvitina kuisa muitiro rinoitwa mune mumaoko mashoma, kana pfungwa nokukurumidza kushandisa yakawanda nguva unogona kuita pakarepo kukanya yakawanda yokupedza, uye inofanira kushandiswa uye chisanganiso sezvinodiwa.

Solution nokuti masonry sezvataurwa pamusoro apa, rakagadzirirwa kuti usasurukirwe dzezvimwe pakati nomumwe nezvidhinha, zvinogumbura kana matombo zvokuvakisa. Uye saka kunaka mhinduro paupenyu kuoma uye simba rose mamiriro uye nokudaro mukurumari unoshanda zvakananga.

Solution nokuti rokuvaka rinoumbwa zviviri yenhengo ndiyo fillers uye binders. Zvichienderana kunyorerana zvinoriumba kusiyanisa zvinogadzirisa mhepo okurapa, mvura okurapa, uyewo hydraulic. Yemanyorero kushandiswa masonry yokutanga mhando mhinduro. Zvichienderana uwandu binders mune mhinduro vari akakamurwa nyore uye zvakaoma kunzwisisa. The brickwork rinoshandiswa kazhinji nyore mhinduro. Panyaya iyi, iyo bhainda iri kana simende kana madota. The kunzwisisa mhinduro pamusoro binders zvinogona kushandiswa panguva Somuenzaniso, simende-lime, madota, simende, ivhu, etc. Izvi zvingaitwa kunzwisisa anechekuita chaiyo batira apo zvakakodzera kuti mhinduro yakanga yakakwirira epurasitiki ehupfumi.

A mhinduro brickwork asi dziya simba. The chakarurama Mucherechedzo akatsunga kana nemamwe mazwi mhinduro inokwanisa withstanding compressive zvinorema. Zvinogadzirisa akashandiswa batira, akaisa zvinotevera mamakisi: 0; 2; 4; 10; 25; 50; 75 uye 100. Kuti uwane chaiwo mabasa - hydro kuvaka uye chinokosha pakuvaka mhinduro ingashandiswa mavanga 150 uye 200. chiratidzo ichi kunoratidzwa ne zvinhu dzichangobva svezheottayavshego kana mhinduro kuti haana kugamuchira elasticity asi zvakakwana uye simba pamusoro nokuisa uye kuomesa. Kuongorora chiratidzo anobudiswa kwazviri mhinduro kuutio pamwe unopinza 7 cm. Uye mushure 28-denvnogo rokuti solidification rinoshandisirwa kwachiri compressive simba. The tembiricha yacho murabhoritari dzinosiyana 15 kusvika 25 Celsius kuti ndinoiitawo. Makavigwa kugadzirwa matatu mharidzo mhinduro uye fenzi dzinoitwa kumavambo akanya, pakati uye pakuguma vaiitawo kwacho.

Uyezve simba unhu dhaka masonry vanofanira mvura chengetedzo uye kutamira parameters. parameters izvi kubvumira mhinduro noruvara kuzadza dzose nzvimbo pamusoro vazvo, izvo zvinozoita kunotungamirira nani zvechadenga mhinduro uye coupling Zvidhinha (matombo) pemvura.
