Oluludaka: zesi kokufanelekileyo ukuba umxube

zokwakha Modern Kunzima ukucinga ngaphandle kokusetyenziswa izinto ezifana lwesamente. Le kwakhiwe kangako, nto leyo eye eziliqela iimpawu kunye neempawu ezenza kube jikelele.

Ukusebenzisa zesamente

Cement udaka, umyinge ogama ziqendu zichazwa yi injongo yaso, zisetyenziselwa iinjongo ezahlukeneyo. Okokuqala, oko - licandelo ibalulekileyo ngekhonkrithi ngokusekelwe lwesamente; Okwesibini, isitena ngokuqhelekileyo uyibeke phezu lwesamente. Phakathi kwezinye izinto, ngaphandle grout akakwazi ukwenza ukuba i-ajenda yale screed emgangathweni okanye iindonga udaka.

Ukudalwa grout

Kuya kufuneka ukuba isamente eneneni owomileyo, isanti, amanzi kunye aggregate entle ukulungiselela isamente yodidi oluphezulu. Olinganise kweekhomponenti ezingundoqo - isanti kunye nesamente - oscillate, ngokubanzi kwi uluhlu ukususela 1: 2 ukuya 1: 6. Kuxhomekeka izixa indlela enemitha izithako, isisombululo uba iipropati ezithile. Umzekelo, ukuba isisombululo ekwakuthululwa eninzi nesanti, oko kubonisa amandla aphezulu, kodwa silahlekelwe kwi plasticity kunye ductility. Ukuba isamente ibe isisombululo kunambathisa kakhulu ukuwina ductility, kodwa kuya kuba ngaphantsi kakhulu ngamandla. Ngoko ke, xa oluludaka lwesamente iveliswa, olinganise ezikhethiweyo eliphakathi - 1: 3 okanye 1: 4.

isisombululo production

Ukuze axove umgangatho isisombululo kunye izithako yayo zixubene ngendlela owomileyo. Kuyimfuneko ukuba licandelo ngamnye umgangatho ophezulu, eyomileyo, uphuqeka kwaye ngaphandle amaqhuma. Kungenjalo umxube owomileyo kuya kuba yimfuneko ukuba anele okanye usile lunamahlwili amhlophe. Ngoku, xa umxube owomileyo ulungele, yongeza amanzi: bawagalele kancinane, likuxhoxhela ngokukhawuleza. Kukholelwa ukuba amanzi guquki ezaneleyo xa unyityilikiswa kufana cream: ke usele ukuba imizuzu eli-15, emva koko inokusetyenziswa ezinye iinjongo.

Noko ke, xa Isisombululo isamente engumxube, olinganise ingahluka kancinci - umzekelo, xa lime igalelwe kuyo. Olu phawu akunyusi kuphela plasticity yesisombululo, kodwa amandla ayo. Standard ratio isamente: isanti: ekalika - 1: 5: 2.

kwezithako

Ukunika isisombululo yazo naziphi na iimpawu ezongezelelweyo, ongeziweyo idla ngokusetyenziswa udaka lwesamente. Oku plasticizers, modifiers ifuthe, superplasticizers, amanzi kunye arhente ukomeleza zombala. Ulwabiwo wolongezelelo ngalinye plasticizers ezicacileyo kunye modifiers nefuthe ukuphucula ukushukumiseka yesisombululo, ukwenza isamente elastic ngakumbi ziyilungele uhlobo oluthile yokusebenza (umz, ngokuthayilisha). Ukuba zingangenwa kuyimfuneko ukunciphisa ifuthe ukufuma namanzi phezu zesamente kunye eziphathekayo; arhente abalwazi kwandiswe amandla. Ke ukuba lo mbala, akunamsebenzi ukwenza nawuphi na umsebenzi ngaphandle yobuhle: isetyenziswa kuphela isisombululo bala kwindawo lombala ethile. Xa udibanisa ubumdaka kulo oluludaka, olinganise kufuneka yabonakala ngqo ngakumbi, ukuze bonakalise mxube ngokwayo kwaye ngokuqinisekileyo akubeki engozini amandla kwesakhiwo, ukuba isisombululo iyaveliswa leyo.

Ukuxuba isamente, uthathe ingqalelo yokuba ngokukhawuleza bakubamba: kwiyure enesiqingatha, yena ligqunywe uqweqwe okuqinileyo. Ngoko ke, kungcono okuxuba iinxalenye ezincinane phambi nje ukusetyenziswa.
