• Shotcrete uye Sprayed Concrete: PCE poda inoshandiswa mu shotcrete uye yakapfapfaidza kongiri zvikumbiro, uko inovandudza kubatana, kupomba, uye kunamatira kwekongiri musanganiswa kune substrate. Izvi zvinoguma nekugadzirisa kwakasimba uye kwakasimba kwekongiri, tunnel linings, uye kudzikamiswa kwemateru.
• Misa Concrete: Munzvimbo dzakakura dzekrete dzakaiswa, dzakadai semadhamu, mabhiriji, uye nheyo, PCE powder inobatsira kuderedza kupisa kwekupisa uye shrinkage nekuderedza mvura yemvura yemusanganiswa wekrete. Izvi zvinovandudza kushanda kwenguva refu uye kusimba kwezvivakwa zvekongiri yakawanda.

3. Zvakanakira PCE Powder:

• Kuvandudzwa Kwekushanda: PCE powder inowedzera kushanda uye kuyerera kwekongiri yakasanganiswa, zvichiita kuti zvive nyore kuiswa uye kubatanidzwa pasina kupatsanurwa kana kubuda ropa.
• Kuwedzera Simba: Nekuderedza chiyero chemvura-ku-samende, PCE powder inobatsira kusimba rakakwirira rekumanikidzika uye kusimba kwekugadzirisa kwezvivako zvekrete.

• Yakaderedzwa Yezvakatipoteredza Impact: PCE poda inobatsira kukwidziridza kushandiswa kwesimende nemvura mumisanganiswa yekongiri, zvichikonzera kuderera kwekabhoni emissions uye kuderedzwa kwezvakatipoteredza tsoka panguva yekuvaka.

PCE poda inosiyana-siyana uye yakakwirira-inoita kongiri musanganiswa inopa akawanda mabhenefiti muindasitiri yekuvaka. Yayo yakanaka particle size, kugona-kudzikisa mvura, uye kupararira kwakanyanya kunoita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa, kusanganisira yakagadzirira-musanganiswa kongiri, precast kongiri, inozvibatanidza kongiri, shotcrete, uye mass kongiri. Nekubatanidza PCE poda mukugadzirwa kwekongiri, mainjiniya uye makondirakiti vanogona kuwana hukuru hwekushanda, simba, uye kusimba mune zvivakwa zvekongiri apo ichivandudza kushanda kwekuvaka uye kusimba.
