Mortar nibikoresho byingenzi byubaka bikoreshwa mumishinga minini nini nini. Ubusanzwe igizwe na sima, umucanga namazi hamwe nibindi byongeweho. Nyamara, hamwe niterambere ryiterambere ryikoranabuhanga, inyongeramusaruro nyinshi zashyizweho kugirango zongere imbaraga zo guhuza, guhinduka no kurwanya amazi ya minisiteri.
Imwe mumenyekanisha ryanyuma kwisi yinyongera ya minisiteri ni ugukoresha polymer zihuza. Binder polymers nibikoresho bya sintetike byongera imbaraga zububiko bwa minisiteri. Biyongera kuri minisiteri mugihe cyo kuvanga hanyuma bakitwara na sima kugirango babe umurunga ukomeye. Imikoreshereze ya polymers ihuza yerekanwe kunoza imiterere ya minisiteri, bigatuma irwanya gucika no kwinjira mumazi.
Iyindi nyongeramusaruro yamenyekanye mumyaka yashize ni redispersible polymer powder (RDP). RDP ni polymer ikoreshwa mugutezimbere imitungo ya minisiteri. Ikozwe mu ruvange rwa polymer isigara ivangwa nifu ya sima, amazi nibindi byongerwaho. RDP iragenda ikundwa cyane bitewe nuburyo bwinshi n'imiterere yihariye.
Kimwe mu byiza byingenzi byo gukoresha RDP muri minisiteri nubushobozi bwayo bwo kongera ubworoherane bwibicuruzwa byarangiye. Iyi mikorere ni ingenzi cyane mubice aho inyubako zikunze kwibasirwa na nyamugigima nubundi buryo bwibiza. Mortars yakozwe na RDP byagaragaye ko iramba, ihindagurika kandi idakunda gucika mukibazo. Byongeye kandi, RDP irashobora kongera imbaraga zo kurwanya amazi, bigatuma iba inyongera yingirakamaro ahantu hagwa imvura nyinshi.
Usibye kunoza imiterere no kurwanya amazi, RDP inatezimbere imikorere ya minisiteri. Iremeza ko minisiteri ikwirakwira kandi igashyira hamwe, bigatuma ubwubatsi bworoha kububaka. Ibi nibyiza cyane mugihe wubaka inkuta, amagorofa, nubundi buso busaba kurangiza neza. RDP igabanya kandi amazi asabwa mugihe cyo kuvanga, bikavamo minisiteri ifatanye hamwe nubusa.
Imikoreshereze yinyongera ya minisiteri nko guhuza polymers hamwe nifu ya polymer isubirwamo ihindura inganda zubaka. Mortars irimo ibyo byongeweho birakomeye, byoroshye kandi birwanya amazi, byemeza inyubako iramba kandi ndende. Twabibutsa ko izo nyongeramusaruro zigomba gukoreshwa muburyo bukwiye. Ibipimo byasabwe nuwabikoze bigomba gukurikizwa kugirango birinde kugira ingaruka kumiterere ya minisiteri.
Inganda zubwubatsi zihora zitera imbere kandi iterambere ritandukanye mubikoresho byubwubatsi rirashimishije. Gukoresha inyongeramusaruro muri minisiteri, nko guhuza polymer hamwe nifu ya polymer isubirwamo, ni intambwe igana inzira nziza kugirango harebwe imiterere irambye kandi ihamye. Izi nyongeramusaruro zemeza ko inyubako ishobora guhangana n’ibiza, imyuzure nibindi bintu bishobora guhungabanya ubusugire bwayo. Kubwibyo, iri terambere rigomba kwakirwa no gukoreshwa mukubaka inzego nziza kandi zikomeye mugihe kizaza.
