ew nibisabwa cyane kugirango imikorere ya beto.Kubera ko guteza imbere ibivanze bifatika muri 1940, iterambere ryayo ntabwo ryahinduye gusa imiterere yimbere ya beto ikomye kurwego rwa microscopique na submicroscopique, ahubwo yanahinduye imiterere ya beto nshya mubikorwa. .Kwivanga kwa beto, bizwi kandi nka dispersant cyangwa plasitike, nibisanzwe bikoreshwa kandi byingenzi.

Gutegura beto nshya ifite imitekerereze myiza, imiterere ya viscous igabanya umuvuduko uri hagati ya sima igomba gusenywa, kugirango ibice bya sima bishobore gukwirakwira mumazi.Hariho ibintu byinshi bigira ingaruka kumikoreshereze ya sima, nkibigize imyunyu ngugu ya sima, imiterere nubunini bwa sima, ubusugire bwa kristu ya minisiteri, hamwe nibikorwa bikora nibidukikije.Ibintu byavuzwe haruguru bigenzura mu buryo butaziguye cyangwa butaziguye kugenzura ihame rya sima mu gihirahiro.Imiterere itandukanye yo hagati irashobora guhindura agaciro k'umuriro w'amashanyarazi ya sima mu gihuru, ni ukuvuga guhindura amashanyarazi ya electrostatike hagati y'ibice.

Iyo umubare ukwiye wa beto wongeyeho kuri beto nshya, ingingo za sima ziyongera, kandi kwanga amashanyarazi hagati ya sima byiyongera cyane, bigatuma igabanuka ryubwiza bwa beto nshya, biteza imbere ituze rya sisitemu yose yo gutatanya.yariyongereye, kandi ubudahangarwa bwateye imbere.

Mubisanzwe, kongeramo urugero rukwiye rwibintu bivangwa na sima birashobora guteza imbere beto nshya kugirango yerekane thixotropy ikomeye.Ibi biterwa no gushiraho firime ya firime ikemuwe hejuru yubutaka bwa sima bwerekanwe kumashanyarazi agabanya amazi no kongera ubushobozi.Niba hari kunyeganyega gato, bizerekana amazi meza.Thixotropy ya beto nshya idafite superplasticizer irakomeye cyane.
