Lexinene eziphathekayo

Eziphathekayo i zokwakha ngumntu, efumaneka yi ekubumbeni Ukuqinisa elandelayo esisiso ezikhethiweyo kunye nomxube ubunjwe. Le ibandakanya zesamente okanye ezinye izinto ezibophelelayo, kwakunye lokubolekwa ecikizekileyo ontlakantlaka kongezwe kwamanzi. Kwezinye iimeko, apho kufuneka okhethekileyo lexinene eziphathekayo, umzekelo, asphalt iteknoloji eziphathekayo, amanzi added, kwaye ukusetyenziswa kwezithako ezizodwa.

amalungelo yayo nokusingqongileyo, kwakunye nokufumaneka ngento ekrwada omkhulu base. Kuyenzeka ukuba balisebenzise kwiimeko ezahlukeneyo yokusebenza. Oko kubizwa ngokuba izinto ezahlukahlukeneyo ukuba isetyenziswa kakhulu kuzo zonke iinkalo kunye namacandelo zokwakha. Kuyinto afana nobushushu enganyangekiyo, isandi abaninzi yaye baziphathe radiation yenyukliya.

Ukuxuba njengentlabathi, isamente, amanzi kunye uhlalutye ivumela ukufumana lexinene wacela eziphathekayo. Umlinganiselo iya kuxhomekeka kwisiqulatho sokufuma zesanti zegrabile, grade isamente kunye amaqhezu. Kwezinye iimeko, kuya kuchaphazela isixa nokwakhiwa nezongezelelo :. Izigxothi Amanzi, plasticizers, njl Umzekelo, ukufumana lexinene M200 eziphathekayo, wasebenzisa isamente grade 400.

Enye kunazo kwale nto ratio ngamanzi-isamente. Kukho uxhomekeke ngqo yamanzi / lwesamente. Oko kukuthi, inowuthi ratio, ngokuqina eziphathekayo. A izinto ukuba ukuxinana 200, inobunzima obukhulu (oko kukuthi kuphela "umnatha"). Lufikelela 2400 kg / m3. Oku kakhulu umthwalo-zithwele izakhiwo eziphathekayo, iintsika zayo, nemivalo yayo, njl imali encinane kakhulu amanzi lexinene eziphathekayo iphezulu kwaye kukho plasticity eliphantsi. Isetyenziswa ngenxa izixhobo, indawo eyimfama ngeenxa zonke endlwini njalo njalo.

Kukho enye impazamo ezidla yenza xa kuxutywa isisombululo. Ishishini unokwakhela kudla kongezwa imali ngokugqithiseleyo amanzi, nto leyo kunciphisa lexinene i ebambekayo kwandisa ukuhamba yayo. Oku kunciphisa kakhulu amandla ayo.

Eziphathekayo iye yokwahlukanisa yaso, endiwenziweyo ngenjongo, iintlobo fillers kunye yokuhlanganisa, iimeko ephilisa, nesakhiwo sayo. Ngesivumelwano, ungakhetha eqhelekileyo (ukuba izakhiwo yoluntu mveliso) kunye ezizodwa (ukwakhiwa kwendlela, yokugquma thermal, ulungiselo ubuciko umsebenzi) eziphathekayo.

Xa uhlobo Umatshini oko udaka, silicate, isamente, shlakoshchelochnyh (asphalt, okanye polimernbeton plasto-). Forms yesixa zayo nazo ezahlukeneyo: aneentunja, exineneyo ngqo, kunye nemixholo yawo - ezinqinileyo, amafutha kunye yorhwebo. Kwakhona, isakhiwo sayo inokuba lubuyisela kwintsunguzi, aneentunja, incindi kunye Pore enkulu. iimeko ephilisa abantu ilandelayo: zendalo, umphunga ephilisa phantsi koxinzelelo umoya okanye esisodwa.

Isalathisi iphambili iimpawu eziphathekayo - ngamandla alo compressive. Le ichaza udidi eziphathekayo. Umzekelo, lexinene i-B25 eziphathekayo. Oku kuthetha ukuba ama-95% yale iklasi iya ukumelana kuxinzelelo ka 25 MPA. Oko kukuthi, incwadi "B", kwaye amanani abonisa uxinzelelo ukuba ukwazi ukumelana olungundoqo megapascals. Ukubala isibonisi yamandla, ekufuneka ukuba ube imiba regulatory akhawunti amandla compressive. Kufanelekile ukuba B25 eziphathekayo mninzi. Ubudala ikhonkrithi ngokwemiqathango kwiklasi, iya kumiselwa amandla compressive yaye ingcinezelo yezihlunu, nto leyo wabelwa kwenye sigaba kuyilo. Zithathelwa ingqalelo iindlela kunokwenzeka sokwakha kunye noyilo imithwalo kubume kunye neemeko lukhuni eziphathekayo.

Ukuxinana kwezi concrete 25 ezilungele Iizilebhu floor, iziseko eziluqilima, nezitya zokutshiza. Oku ngoyena usetyenziswa rhoqo ezi iinjongo eziphathekayo. Ukongeza, ukusetyenziswa abakhi izinto ezinjalo kunye nezinye izakhiwo unoxanduva indawo. ingxinano obubambekayo 25 iqinisekisa Obusemagqabini ubunjani zezakhiwo igqityiwe, ngokuxhomekeka ke ukuba imveliso uthenge iyahambelana ngokupheleleyo iinkcukacha ashicilelwe.
