Konkrete inopindika inogadzirwa nei?

Pervious kongiri, inozivikanwawo sekongiri inopindika kana porous kongiri, inogadzirwa uchishandisa musanganiswa wesimende, aggregate uye mvura, yakafanana nekongiri yenguva dzose. Zvisinei, kuitira kuti iwane kukwana kwayo, kune mimwe misiyano inokosha mukuumbwa kwayo. Musiyano mukuru ndewekushandiswa kweakakura aggregates uye kuderedzwa kwehuwandu hwemhando dzakanaka mumusanganiswa. Izvi zvinogadzira zvivharo zvakakura kana nzvimbo mukati mekongiri inobvumira mvura kupfuura nyore. Iyo aggregate inoshandiswa inogona kuve yemhando dzakasiyana senge dombo rakapwanyika, matombo kana porous lightweight zvinhu. Kuve nechokwadi chekusimba uye kusimba kwekongiri inopindika, simende nemvura zvinoramba zvichikosha zvinhu. Simende inoshanda sebhainda kuti ibate muunganidzwa pamwe chete, nepo mvura ichidikanwa kune hydration panguva yekurapa. Kuwedzera kune yakajairwa kongiri zvinongedzo, pervious kongiri inogona kunge iine zvimwe zvinowedzera kana admixtures. Izvi zvinowedzera zvinowedzera zvinhu zvekongiri, zvakadai sekuwedzera simba rayo, kuderedza kutsemuka, kana kuwedzera kukwana kwayo. Mimwe mienzaniso yezvinowanzo shandiswa zvinowedzerwa mukongiri inotenderedza inosanganisira silica fume, nhunzi madota, kana zvimwe zvinhu zvepozzolanic. Zvinhu izvi zvinobatsira kuwedzera kusungirirwa mukati mekrete matrix, zvichikonzera nzvimbo yakasimba uye yakasimba. Pakazere, iwo chaiwo zviyero uye zvinhu zvinoshandiswa zvinogona kusiyana zvichienderana nekwakagadzirirwa kushandiswa kwekongiri uye inodiwa permeability. Nekudaro, izvo zvakakosha zvekongiri inopindika simende, akaunganidza uye mvura, ine chero inodiwa yekuwedzera inowedzerwa kuti iwane iyo permeable zvivakwa.

Kana uine mibvunzo yakananga kana zvimwe zvinodiwa chaizvo nezve kongiri inopindika, unogona kubvunza mugadziri wehunyanzvi.
