Yakakosha hunyanzvi uye hupfumi mabhenefiti emhepo-inopinda mumiririri anoshandiswa mune yekutengesa kongiri
Mhepo-yekupindira Admixture ndeyekushambadzira iyo inogona kuburitsa huwandu hukuru hwechidiki, dense uye yakagadzikana mabhuru kana yakavhenganiswa kuita kongiri. Kusimba kwakadai sekukanganisika kwechando uye kusakwana. Kuwedzerwa kwemhepo-yekushambadzira yekushambadzira kongiri inogona kudzivirira iyo yechipiri adsorption yekuparadzaniswa masangano emisangano mukongiri uye nekuvandudza kutendeuka kwekutengesa kongiri. Parizvino, mhepo-inopinda mumiririri chimwe chezvinhu zvakakosha mune yekutengesa kongiri yekubvumirana (vamwe vari kuderedza mvura uye kudzoreredza). MuJapan uye nyika dzekumadokero, hapana kana kongiri isina mhepo-yekupinda mumiririri. MuJapan, kongiri pasina mhepo-yekupindira mumiririri inonzi yakakosha kongiri (senge inobvumirwa kongiri, nezvimwewo).
Mhepo-yekupinda ichakanganisa simba rekongiri, iyo inoreva bvunzo dzinowanikwa pasi pemamiriro emamiriro emvura uye yemvura. Kana iyo mhepo yemukati inowedzera ne1%, simba rekongiri rinozoderedzwa ne4% kusvika 6%, uye kuwedzera kwemhepo-yekupindira mumiririri inozodzikisa simba rekongiri. Chiyero chemvura chinowedzera kwazvo. Yakaedzwa neNaphthalene-based Superplasticastizer. Kana iyo kongiri yemvura kuderedzwa ndeye 15.5%, iyo kongiri yemvura kuderedza inodarika 20% mushure mekuwedzera iyo madiki emhepo, iyo, iyo yekudzora mvura yekudzora huwandu hunowedzera ne4,5%. Kune yega yega 1% kuwedzera kwemvura, simba rekongiri rinowedzera ne2% kusvika 4%. Saka, chero bedzi huwandu hwemhepo-yekupinza
Mumiririri anonyatsotongwa zvachose, kwete chete simba rekukongiri haizodzimi, asi rinowedzera. Zvekutonga kwemukati wemhepo, miedzo yakawanda yakaratidza kuti mhepo yezvinyorwa zvakaderera-simba kongiri inodzorwa ne5%, sosi yekongiri kune 4% kusvika 5%, uye yakakwirira-ine simba kongiri inotongwa na3 %, uye simba rekongiri harizodzikiswe. . Nekuti iyo mhepo-inopinda mumiririri ane mhedzisiro dzakasiyana pasimba rekongiri ine akasiyana emvura-simende retiosi.
Kufunga nezvemvura-kuderedza mumiriri wemhepo, paunenge uchigadzirira kongiri yekushambadzira, amai vemitambo yekushambadzira kwemvura, uye kubatsirwa kwehupfumi kunofungidzirwa.
