I-Concrete enamandla ngakumbi nge-Smart Fibers

PVA fibers are a smart option for improving cement and concrete. Le misonto eyenziweyo ixutywa kakuhle kanye kwikhonkrithi emanzi. Banceda ukulawula iintanda ezidala ngexesha lokoma kunye nokuqina. Ngokungafaniyo nentsimbi, Iintsinga zePVA azidusi . Oku kuthetha ubomi obude kwisakhiwo sakho.

Iikontraka ziquka iifiber zePVA ukuya kwimigangatho, imiphezulu eludongeni, iziqendu, kunye neendlela. Iintsinga zilinganisa izixhaso ezincinci ngaphakathi kwekhonkrithi. Babamba umbandela kunye xa kukho uxinzelelo okanye intshukumo. Oku kunciphisa i-fractures yomhlaba kwaye igcina indawo ephezulu. Uphucula ukuqina ngaphandle komsebenzi owongezelelweyo.

Kulula ukuyisebenzisa, Iziphumo ezinkulu

You can mix PVA fibers right into your normal concrete set. Akukho zixhobo zikhethekileyo okanye amanyathelo afunekayo. Iintsinga zisasazwa ngokulinganayo kwaye zibophe kakuhle kunye ne-samente paste. Bakhulisa ukuxhathisa isiphumo kunye namandla. Kwanamaleko abhityileyo ekhonkrithi agqibe ekubeni athembeke ngakumbi.

Ezi fayibha zikwanceda kwishotcrete kunye nomsebenzi weprecast. Bayicutha ilahleko ebuyela kwi-rebound ngexesha lokufafaza. Oko konga izinto kunye nexesha. Kwaye kwakhona, banciphisa amathuba okuqhekeka kweentanda zeplastiki– imiba eqhelekileyo kwimozulu efudumeleyo okanye eyomileyo.

Yakhiwe Ukugqibela, Yenziwe Yalula

PVA fiber admixtures offer actual worth. Banyusa ukusebenza ngelixa begcina amaxabiso ehlisiwe.
