Systems simenti, kongiri, uye mongwe inogona kuvhiringidza kune avo vari kutanga kunze, asi musiyano wekushamwaridzana pwere yakanaka (isina kumbobvira yashandiswa ndega), dhaka yakagadzirwa neSimende nejecha, uye kongiri yakagadzirwa simende, jecha, uye gravel. Kuwedzera kune avo akasiyana-siyana, mashandisiro avo zvakare akasiyana chaizvo. Kunyangwe vabhizinesi vanoshanda nezvinhu izvi zuva nezuva vanogona kuvhiringidza mazwi aya mumutauro wecoluquial, sekusimerwa kunowanzoshandiswa kurevesa kongiri.
Simende
Simende chisungo pakati pevakongiri uye dhaka. Iyo inowanzogadzirwa nedombo, ivhu, shells uye silica jecha. Izvo zvinhu zvinopwanywa uye zvobva zvasanganiswa nezvimwe zvinosanganiswa, kusanganisira iron ore, uye wobva waomesa kusvika pamadhora mazana maviri nemakumi manomwe emakore. Izvi zvinyorwa, anonzi clinker, ivhu rakakura hupfu hwakanaka.
Iwe unogona kuona cement inotaurwa seye portland cement. Imhaka yekuti yanga yatanga kugadzirwa muEngland muzana ramakore rechi 19 neLeids Monon Joseph Aspdin, akafananidza ruvara kusvika pamatombo kubva kuchitsuwa chePortland, kubva pamahombekombe eEngland.
Nhasi, simendi yePortland ichiri chinhu chinowanzoitwa simende. Icho "hydraulic" simende, iyo ingori zvinoreva kuti inogadzika uye inoomesa kana ichisanganiswa nemvura.
Kongiri
Pasi rese, kongiri inowanzoshandiswa sehwaro hwakasimba uye huwandu hwenhengo ye chero mhando yechivako. Izvo zvakasiyana pakureva kuti zvatanga semusanganiswa wakareruka, unobva wazova mvura, elastic zvinhu zvinogona kuumba chero furu kana chimiro, uye pakupedzisira chave dombo, sezvinoita zvinhu zvakaoma izvo zvatinodaidza kongiri.
Concrete ine simende, jecha, gravel kana imwe yakanaka kana coarse aggregates. Kuwedzerwa kwemvura kunoita kuti ive iyo simende, iyo ndiyo chinhu chakakosha kusunga musanganiswa pamwe chete kuti ugadzire chinhu chakasimba.
Iwe unogona kutenga yakagadzirirwa-yakagadzirwa kongiri inosanganisa mumabhegi ayo musanganiswa musanganiswa, jecha, uye gravel pamwechete, uye zvese zvaunoda kuti uite mvura.
Izvi zvinobatsira kumapurojekiti madiki, senge ancharing fenzi posts kana zvimwe zvifeve. Zvemapurojekiti makuru, iwe unogona kutenga mabhegi eiyo simende uye uzvisunge nejecha uye uzvipe muvhiri kana mumwe mudziyo wakakura, kana kuraira premixed kongiri uye yakadururwa uye yakadururwa.
Dhaka
Dhaka rakagadzirwa nejecha nejecha. Kana mvura ikasanganiswa neichi chigadzirwa, simende inoitwa. Nepo kongiri inogona kushandiswa yega, dhaka inoshandiswa kusungirwa zvidhinha, dombo, kana zvimwe zvakaoma mamiriro ezvinhu pamwechete. SEmining Sinosanganisira, saka, nenzira kwayo, zvinoreva kushandiswa kwesimbe kusanganisa dhiri kana kongiri.
Mukuvakwa kwezvidhinha patio, motsi dzimwe nguva inoshandiswa pakati pezvidhinha, kunyangwe mune ino kesi hazvishandiswe. Mumatunhu ekumusoro, semuenzaniso, maumbwa anokanganisa zviri nyore munguva yechando, saka zvidhinha zvinogona kungoiswa pasi pamwechete, kana jecha rakawedzerwa pakati pavo.
