Inkcazo ye-Concrete Admixture: IFayibha ye-PVA yokuSebenza ngokuPhakamileyo iFayibha eFanelweyo eQiniswayo kwiSicelo seSeismic

Isishwankathelo sento

I-PVA fiber yintsinga eyenziwe ngepolymer eyenziwe nge-polyvinyl alcohol. It is specially designed for use in high performance fiber reinforced concrete (HPFRC). This admixture substantially enhances the sturdiness, i-ductility, and split resistance of concrete. These high qualities are crucial in structures located in earthquake-prone locations.

Imfihlo ibandakanya

The fiber has high tensile strength and solid bonding with the cement matrix. It uniformly disperses in the concrete mix without clumping. This ensures regular performance throughout the structure. The product is alkali-resistant, so it remains steady and effective gradually inside concrete. It also does not wear away, unlike steel fibers, that makes it excellent for long-lasting longevity.

IiNgcaciso zobuGcisa

– Ubungakanani: 6 mm uya 18 mm
– Ubungakanani: 20 ukuya 40 iimicrometers
– Ukuqina kokuqina: ≥ 1,600 MPa
– Elastic modulus: ≥ 40 GPA

Oku kugcina isakhelo sime ixesha elide kulo lonke inyikima.

Real-World Usebenzisa

Iikontraka zisebenzisa ikhonkrithi eyomelezwe ngePVA kwimisebenzi emininzi ebalulekileyo. You’ll find it in bridge piers , itonela linings zeselula , and constructing structures situated in energetic fault locations. It’s additionally typical in keeping wall surfaces and shear walls where sudden side forces are anticipated. Ngenxa yokuba iifiber zePVA zidibana kakuhle nesamente, banceda ukulawula ububanzi bokuqhekeka kwaye bayeke iifracture ezincinci ekwandiseni ngokukhawuleza.

IiNzuzo zeQhinga ngaphezulu koBuchule obuMgangatho

I-rebar yentsimbi iyodwa ayinakuyeka ukuphuka kwangoko. Iintsinga zePVA zilayisha loo nto. They improve ductility , ebonisa ukuba ikhonkrithi iguquguquka kancinane ngaphandle kokonakalisa. They also increase impact resistance and tiredness performance . Ngokungafaniyo nentsimbi, Iintsinga zePVA azidusi. Oku kuzenza zibe zezona zifanelekileyo kwimozulu efumileyo okanye erhabaxa. Isiphumo sisimo esihlala ixesha elide esinokugcinwa kancinci.

Ngokuchanekileyo indlela Esebenza ngayo kwindlela

Iingcali zixuba iintsinga ze-PVA ngqo kwikhonkrithi kwisityalo se-batching. Akukho zixhobo zikhethekileyo ezifunekayo. Iintsinga zisasazeka ngokulinganayo ngomxube. Xa ibekwe kwaye iphathwe, ikhonkrithi ibonisa ukufunxa amandla ngcono kakhulu ngexesha lokungcangcazela. Iinjineli zixhomekeke kwezi ntshukumo ukuze zanelise iikhowudi ezingqongqo zokhuseleko lwenyikima. Iimfuno ezininzi zolwakhiwo lwangoku zamkela okanye zicebisa imixube eyomelezwe yifayibha kwiindawo ezinomngcipheko ophezulu.

Ukusebenzisa i-PVA fiber yinto ehlakaniphile, indlela yoqoqosho yokuhlaziya ukusebenza kwekhonkrithi. Kubandakanya ukomelela apho kubaluleke kakhulu– xa umhlaba ufuduka ngokukhawuleza kwaye ngamandla.
