Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
Isihloko: IiFom qhina zinxulunyaniswa nokuba yeyiphi iNqobo yeConcrete?
(IiFom qhina zinxulunyaniswa neyiphi iNkonkrithi?)
Njengoko ishishini lokwakha liqhubeka nokukhula, ikhonkrithi ibe yenye yezona ntlobo zixhaphakileyo zezixhobo ezisetyenziswa kumsebenzi wokwakha ehlabathini lonke. Iyaziwa ngokuhlala kwayo, amandla, kunye nokumelana neemeko zemozulu ezinzima. Nangona kunjalo, ayizizo ezi mpawu zomzimba kuphela ezenza ikhonkrithi idume kakhulu njengoko idlala indima ebalulekileyo ekudaleni izakhiwo ezahlukeneyo kunye nemisebenzi esiyisebenzisa yonke imihla..
Enye yezona zinto zibalulekileyo zekhonkrithi yimodulus yokuqina. Oku kubhekiselele kwindlela enokugotywa ngayo okanye ukubunjwa ngokulula ngayo. Imodyuli ye-elasticity ichatshazelwa zizinto ezahlukeneyo ezifana nobudala, ukwakheka, kunye neemeko zokusetyenzwa. Imodyuli ephezulu ikhonkrithi kulula ukugoba kunemodulus ikhonkrithi ephantsi ngenxa yoxinzelelo oluphezulu lwempendulo. Ukongeza, imodyuli yokwaluka ichaphazela ukumila kunye nenkangeleko yeziqwenga zekhonkrithi xa zibekwe kunye.
Omnye umba obalulekileyo wekhonkrithi yi-porosity yayo. I-Porosity ibhekiselele ekubeni singakanani na isithuba esithathwa yi-aggregate okanye umgubo kwisithuba esithile. Ipesenti ephezulu ye-porosity ithetha ukuba umoya okanye amanzi amaninzi angahamba kwizinto eziphathekayo, ukuyenza yomelele kwaye ixhathise ukufuma. I-Porosity iphenjelelwa zizinto ezifana nodidi lwe-aggregate esetyenzisiweyo, ubume bekhonkrithi, kunye neemeko zokusingqongileyo.
Ikhonkrithi ikwasetyenziswa ngokuqhelekileyo ukukwazi kwayo ukubamba kunye nokwandisa ngexesha lenkqubo yokufakwa kwamanzi. Le propati yenza ukuba ilungele izakhiwo zekhonkrithi ezifuna ukubonakaliswa kwamanzi amaninzi. Ngaxeshanye, ukukwazi ukwandisa ngexesha lenkqubo ye-hydration kwakhona kwenza ikhonkrithi ivumelane nokutshintsha kweqondo lokushisa kunye nokufuma, ukwenza ukuba ilungele iimeko zemozulu ezahlukeneyo.
Ukongeza kwezi mpawu zomzimba, ikhonkrithi yomelele kakhulu kwaye iyamelana nokuhlwa. Ukonakala kwenzeka xa iintsimbi nezinye izinto zidibana namanzi kunye neoksijini. Ikhonkrithi yenziwe kusetyenziswa izinto ezikumgangatho ophezulu kwaye zinyangwa ukunqanda ukurusa kunye nokwakheka kweeasidi, iyenza ikwazi ukumelana nomhlwa. Oku kwenza kube lukhetho oluluncedo kwizicelo apho umonakalo wamanzi uxhalabisa.
Nangona kunjalo, ngelixa ikhonkrithi yenzelwe ukumelana neemeko ezinzima, alinazo iziphene. kukuba ixhomekeke ekuqhekekeni kunye nokuphuka phantsi koxinzelelo olunzima okanye impembelelo. Ukunciphisa lo mngcipheko, abaqulunqi bahlala besebenzisa ubuchule obunjengokuqinisa ikhonkrithi, amandla oomatshini, kunye neenkqubo zokuxhasa umthwalo oguquguqukayo.
Ekugqibeleni, ukufumaneka kweentlobo ezahlukeneyo zemixube yekhonkrithi yenye into ebalulekileyo emisela ukusebenza kwezakhiwo eziphathekayo. Iindidi ezahlukeneyo zinamandla ahlukeneyo, m ye hydration, kunye namazinga omisa, zonke zichaphazela ukukwazi kwekhonkrithi ukufezekisa iipropati ezijoliswe kuzo. Ngoko ke, kubalulekile ukukhetha uhlobo oluchanekileyo lomxube wekhonkrithi ngokusekelwe kwiimfuno ezithile zeprojekthi.

Ukuququmbela, ikhonkrithi yinxalenye ebalulekileyo yoshishino lokwakha, kunye nomzimba wayo, zobugcisa, kunye neempawu zombutho zidlala indima ebalulekileyo ekumiseleni ukusebenza kwayo nokuguquguquka. Ukuqonda ubudlelwane phakathi kwefomu, imodyuli, i-porosity, ulwandiso, ukumanzisa, kunye nokuhambelana nemathiriyeli kubalulekile ekuyileni izakhiwo zekhonkrithi ezisebenzayo ezihlangabezana neemfuno zabaxumi abohlukeneyo.
