Ikalika-pozzolan isamente: imveliso kunye nokusetyenziswa

clinker izinto isamente Pozzolan luhlobo olungumgubo kunye nomphetho kwiipropati, lisekelwe ekhoyo kunye nezongezelelo ezahlukeneyo. Weight ezuza isakhiwo eplastikini zoqhagamshelwano ngamanzi kwaye Ukuguqulwa kolwelo phezu omiswe.

production

Xa izityalo ezizodwa eyenziwe yekalika-pozzolan isamente, imveliso leyo endinga indlela yokwenziwa umjikelo opheleleyo. Ngokungafaniyo kwezi zakhiwo kwimizi kukuba yokuba gumbi lokugaya kusetyenziswa ukugaya nezongezelelo omisa. Benza njengoko zizinto zendalo izimbiwa - gliezh, diatomite, Kungenzeka ukusebenzisa iimveliso ze imveliso yezamandla.

A nobuninzi kwezinto ezongezelelweyo equlethwe ezifana eziphathekayo, njengokuba isamente pozzolan. Yenziwe ngoobani kunye umyinge izithako eziphembelela iimpawu zokusebenza. Ukutshintsha ixesha Ukuqinisa ngexesha egqugqisayo gypsum idityaniswe, isixa-mali salo kufuneka abe ngaphezulu kwe-3% of ubunzima iyonke.

isakhiwo

okuguba Iyonke, ukuba indlela uthandwayo lemveliso yekalika-pozzolana isamente, inomsebenzisi eyahlukileyo ngohlobo ukugaya clinker kunye gypsum nezimbiwa elements esebenzayo lokusila ekhethekileyo multi. Phambi ezi izithako batyunyuzwa, wazisa kwinqanaba ukufuma ezifunekayo igubu yokomisa. Kubalulekile ukuphawula ukuba ukunyusa umlinganiselo yesabelo kwezithako kunciphisa iindleko eziphathekayo.

inkqubo isamente Ukuqinisa ikalika-pozzolana uvakalelo utshintsho obushushu. Kwiqondo lobushushu ukuya ku 14 degrees umxube waphawulwa Ukuqinisa kade. Le nkqubo ngokoqobo ime xa lobushushu kokugquma na izinyuko-5. Ngenxa yale nzima kakhulu ukusetyenziswa kwezinto kwixesha abandayo kwisithuba evulekileyo.

Xa pozzolan lwesamente efanayo ndandingaziqondi kakhulu ngokukhawuleza kwiqondo lobushushu eliphezulu kwaye esiphakame kunesiqhelo Portland isamente. Ukwandisa ukusebenza kumacandelo eyenziweyo, zingakotshwa phantsi unyango olunye ubushushu kubushushu kuluhlu degrees 80-90.

Ubuhle nobubi

isamente Pozzolan, iimpawu ezivumela ukuba zenze ngexesha Ukuqinisa izinto ezifana calcium hydrosilicate hydroaluminate kunye ezahlukeneyo impembelelo encinci kunaleyo eqalisiweyo isamente eqhelekileyo inika ukuxhathisa nangakumbi iimpembelelo saline kunye namanzi acocekileyo. Phakathi ezilungileyo kubalulekile ukukhumbula oku kulandelayo:

• pozzolan isamente luphawulwa ukuyilwa neentanda ezimbalwa;
• olukumgangatho ophezulu adhesion ukuya izinto eziphathekayo wezifundo;
• Ukuphathwa lula;
• iimpawu ekwakheni ubuhlobo kakhulu;
• Lo mxube pozzolanic buyeyona ubungakanani enkulu ngekhonkrithi okanye udaka kunye ukuselwa olufanayo eziphathekayo kunye nezinye iindidi kwimixube.

Kodwa ke ngaphandle ethile:

• imfuneko yokusebenzisa ngakumbi amanzi udonga;
• yokugcina elide kunciphisa umsebenzi izinto eziqulathwe.

Oko Ufanele Ukwazi

Ngaphandle isamente ayenzi nayiphi na iprojekthi isakhiwo, lo gama eRashiya ihamba phambili ekuvelisweni kwale nto. Naziphi na iinguqulelo zayo kubume uluhlu amachiza kuba kudidi silicates, le additive ekhoyo kwi ekwakhiweni ngokohlobo lesilicon dioxide. Njengesiseko inke- clinker isamente nto imiselwe yekalika nodongwe, badubula elidlulileyo. umhlaba Diatomaceous lisebenza elubhorha. Senziwe ngexesha imveliso kunye nokusetyenziswa uthuli isamente kukungakhuseleki elide ebangela uphuhliso bronchitis yaye kwiimeko ezinqabileyo - pneumoconiosis, walungiselela excess lesilicon dioxide umaleko, osekwe lwesamente pozzolanic.

Silicosis luhlobo kakhulu lwe pneumoconiosis kabanzi kunazo ezifunyenwe ngexesha kuphuhliso esebenzayo zobunjineli kunye noshishino kwemigodi ngenxa yokuba kokwakhiwa ukusebenza kuchaphazela inani elikhulu zwi uthuli. Esi sifo ixhaphake kakhulu kubantu ezinxulumene ukuhluzwa lenyengane, uphuhliso imigudu, yodongwe zokwakha kunye nemixube eliyinjubaqa.

Ezinye iindlela zemveliso

Pozzolan isamente, ogama iipropati nabo baxhomekeke kwi-nkqubo, singenziwa kuphela kwizityalo kodwa kwiziza zokwakha i ngokwabo usebenzisa izibonelelo nokutshixiza-yokomisa. Bona yomile kunye neeminerali, ngaba umhlaba kunye oxutywe kobukhulu, mhlawumbi nokutshixiza ngaxeshanye izithako. Oku kunciphisa ingxinano yezithuthi, kuthuthwa kuphela izinto clinker nezimbiwa ngokwabo ziveliswa kwindawo yokwakha. Phakathi eziluncedo enjalo njengobuchule kufuneka kuqwalaselwe amathuba yokutshintsha ubume izinto esandul ezenziwe kunye fillers. Kodwa ke ukusetyenziswa kwezibonelelo ezizodwa bugwetyelwe kuphela zokwakha ininzi kakhulu.

Pozzolan isamente: sebenzisa

Izinto ezininzi ezisetyenziswayo kakhulu abazifumene zokudalwa ufakelo lwesamente nezinto eziphathekayo komhlaba kunye nokusetyenziswa kwamanzi, nto leyo siyasebenzisana sulfate kunye namanzi amatsha. Ngaba isetyenziselwe neencindi kunye isakhiwo, bume leyo ebonakala ngamazinga aphezulu ukufuma. Kwakhona ukusetyenziswa kuxhaphakile izakhiwo zobunjineli ngesanti kubunzulu baphantsi yabhalwa vnutrimassivnogo eziphathekayo.

Sebenzisa izakhiwo concrete ezisentlabathini kulinganiselwe ngenxa iimpawu ukunganyangeki iqabaka ephantsi, ingakumbi emoyeni kunciphiso Ukuqinisa. Oku kusekelwe nokomisa nkqi, onako ukuyeka inkqubo Ukuqinisa kwaye kungakhokelela ekubeni shrinkage ebalulekileyo. Kwakhona indalo engathandekiyo lweziqalelo noshowo pozzolan yesamente, ukuba zisetyenziswa phantsi thawing ngamaxesha athile kunye neGauteng, omisa kunye ukuxovwa.

amandla

Pozzolan ukwakheka isamente, iimpawu, izicelo ezibonelela amandla ezinomahluko lweziqalelo olwalusele, ixesha elide, oko kubangelwa isixa ngecalcium silicate kwakhiwa. Ngokuba izinto esibonakala ukunyuka elide ngamandla ngenxa Ukwehla ubunzima iyonke net ngesamente, yonke into igalelo izithako ezongezelelekileyo. Ukukhawulezisa lukhuni ukuphilisa kuqatshelwe ngokuhlanganisa oxide calcium dust esebenzayo, izinto ezibonakalayo amandla efanayo kwamanye grout lwesamente. Ngoko ke, kokuhlala ixesha elide kwindawo efumileyo.

imfuno ebangwayo yamanzi

Pozzolan isamente, olusekelwe phezu diatomite kunye Tripoli, zibandakanya imfuno yamanzi banda, okukhokelela ixesha kancinci of Ukuqinisa lokugqibela. Ukwenza isamente oluludaka imali efunekayo zolwelo kwandisa ngokuxhomekeke wezimbiwa izinto esebenzayo. zokunciphisa kwayo iqatshelwe phambi kwezithako kwi ukwakhiwa tuff kunye kwingoma.

Ukwanda kwemfuno yamanzi ayinqweneleki kuba inegalelo kwingcungela ngakumbi olu hlobo zesamente kuthelekiswa namanye. Ukongeza nothuthu ayitshintshi umlinganiselo wokubanzi efunekayo ukuba axube. Oku kungenziwa ugalelwe kunye zombini umxube eziphathekayo kunye ngokwayo isamente. Umgangatho zokufunda hayi yancitshiswa nokuba uthuthu uya kutshintshwa kuze kufakwe inxaxheba.
