Funda iziSeko ngaphambi kokubeka iMyalelo.
Ngaba ulungele ukulungisa ukukhonkxa ikhonkrithi ? Ukuba ucinga njalo, phinda ucinge kabini. Unokwenza umyalelo wokudibanisa ukungalunganga, ukunciphisa imali engenayo okanye ukunika umkhiqizo ongeyena umxube wokudibanisa ukhonkrithi. Lapha siye salungiselela uluhlu lweengcebiso ezivelisayo eziza kukunceda ngaphambi kokuyalela ukudibanisa ukukhonkxa kwekhonkrithi.
I-Ready Mix I-Concrete Force
Enye yezona zinto zibaluleke kakhulu ngaphambi kokuyalela ukudibanisa ukukhonkxa kwekhonkrit wazi ukwazi okufunekayo okunamandla .
Ngokuqhelekileyo, ikhonkrithi eqinisiweyo ephakathi kwama-3 500 ukuya ku-4,000 i-psi isetyenziswe ngokunyathela kunye ne-slabs kwibanga; phakathi kwama-3 500 ukuya ku-5,000 i-psi kwi-slabs ezimisiwe, imizila kunye neebhanki; kunye neendonga kunye neentsika zifuna ukuba phakathi kwama-3,000 ukuya kuma-5,000. Xa ikhonkrithi engaqinisekisiwe isetyenzisiwe amandla ahlukeneyo kuya kufuneka. Ukuba uyisebenzisayo ngeenyawo kunye neendonga, amandla ekhonkrit of 2,500 psi anganelanga ixesha eliphakathi kwe-4,000 ukuya ku-5,000 psi liyadingeka ukuze kwenziwe iipayipi. Ikhonkrithi yangaphandle esetyenziselwa ukuphucula ekhaya kufuneka iyalwe ngamandla avela phakathi kwama-3 500 ukuya kuma-4 500 psi.
Amaqumrhu aKhonkcisiweyo okuThengisa
I-aggregate ephezulu kakhulu kufuneka icaciswe xa kulungiswa ukudibanisa ikhonkrit. Ukuba usebenzisa i-aggregate enkulu ebunqamlekileyo kwisiqendu esiphantsi apho umgangatho wensimbi uphakamileyo, ngoko unokuba ungena kwiingxaki ezinkulu ngenxa yobusika. Ubuninzi bobuninzi obudibeneyo obunikwe umyalelo kufuneka bubekwe yi-American Concrete Institute Standard (ACI) kwaye kuxhomekeke kwisithuba sokuqinisa intsimbi , ngaphakathi kweefom zefomathi kunye nezihlanganisi ezikhoyo.
Ubuninzi bobuninzi abuyi kudlulela i-1/5 inqanaba elincinci lomgangatho wangaphakathi kwaye akuyi kuba mkhulu kune-¾ ulwahlulo phakathi kwee-re bars. Ngokuqhelekileyo, unjiniyela wezakhiwo uya kunika isikhokelo kunye nolwalathiso ngokubhekiselele kwisilinganiselo esipheleleyo.
I-Ready Mix Concrete Slump
I-Slump yinto ehambelana nekhonkrit xa ikwafakwa .
I-Slump iya kucaciswa ngokuphantsi nangona iya kuhluka ngokuxhomekeka kwendawo yokwakha, uhlobo lwefomathi, kunye ne-slope okanye indawo apho iya kufakwa khona. Iiplitshi ziyakunikwa imilinganiselo ye-ACI nangona singakwazi ukuncomela oku kulandelayo:
- Udonga olusisiseko olusisiseko kunye namanyathelo okuhamba: Ukuhluma kuya kuba phakathi kwama-2 no-5 intshi
- Izilwanyana, ii-caissons: ubuncinane be-1 intshi, ubuninzi bee-intshi ezine-intshi
- I-Slabs, imitha, iikholomu zokwakha kunye neendonga eziqinisiweyo: ubuncinane obu-3 intshi kunye ne-6 intshi ephezulu
- Iipravements: ubuncinane be-2 intshi kunye ne-intshi e-3 intshi
- Ubunzima beekhonkrithi: Ubuncinane be-1 intshi kunye nobukhulu obungama-3 intshi
UkuLungisa ukuThengiswa kweMixikiti
Ikhonkrit Ready Mix iqhelekelelwe ngamagidiyubhi okanye ii cubic metres. Iloli eliqhelekileyo liyakwazi ukuhambisa phakathi kwe-9 ukuya kwe-11 ii-cubic yards amandla angaphezu kwamanani angaphantsi angakholelwa kwakhona, kodwa uya kuhlawula ngokukhawuleza amandla okusala kweloli engasetyenziswa. Isixa sokunikwa kwekhonkrithi siya kuxhomekeka nalapho kuya kufakwa khona kunye nefom esebenzisiweyo. Njalo uvumele ikhonkrithi ethile, esivame ukuhluka phakathi kwama-5 ukuya kwe-10 ekhulwini lekhonkrete eyongeziweyo. Kwindawo yokubeka indawo emacaleni, phinda ubude obude amaxesha ububanzi obuninzi, ezinyaweni, kwaye ulwahlule ngo-27. Le mali iya kuba yileyitiyiti efunekayo yekhonkrit efunekayo.
Xa usebenzisa i-cylindrical shape, efana nekholomu, ulinganise ubude bayo, wande ngo-3.14, ngoko ke ngekwere yendawo ye-cylindrical, uze uhlule ngo-27.
Ezinye Iingcebiso eziPhambili eziPhambili eziPhambili
Khumbula ukwazi kwakhona ukuba usebenzisa i- mix mix , cacisa ukuba indawo engakanani indawo yokusebenza isuka kwisityalo se-batch, ixesha lokufika lekhonkrithi oyicelayo, ukukhethwa kweemoto zamakhonkco, ukucacisa ukuba ufuna i-fiber okanye iplastiki, ukuba ukhonkrithi uza kubeka njani (ukukhangela, umpompo, i-barbarrow, njl.), umxube omoya okanye ongenawo umoya , umyinge we-mix mix ready, umntu oqhagamshelana naye, inombolo ye-ID yomxube wekhonkrithi kunye nenjongo yekhonkrithi. Ekugqibeleni, yazisa ikhonkrit batch imimiselo yendawo apho ukuxuba okulungele ukubekwa khona (umthambeka, uhla lwephahla, indawo ephantsi, isiseko, uphahla) okanye nayiphi na inkcazelo efanelekileyo enokuchaphazela ishedyuli yokuphalaza.
