Mu myaka ya vuba aha, inganda z'ubwubatsi zabonye impinduka ikomeye mu gukoresha beto ikora neza kugira ngo ihuze n'ibikenewe cyane mu mishinga y'ibikorwa remezo bigezweho. Kimwe mu bintu by'ingenzi bigize beto ikora neza ni icyuma gifunga, gihuza ibice byose hamwe kugira ngo kibe matrix ikomeye kandi irambye ya beto. Mu moko atandukanye ya kole, ikoreshwa rya kole ya polymeric ryakunzwe cyane kubera ubushobozi bwayo bwo gutanga imiterere yifuza nko kongera kuramba no koroha.
Imwe mu mishinga ikoreshwa cyane muri sima ifite ubushobozi bwo hejuru ni RDP (Redispersible Polymer Powder). Imishinga ikoreshwa muri sima ni ifu yumye ishobora kuvangwa byoroshye n'ibindi bintu kugira ngo ikore imvange ya sima ifite ubushobozi bwo koroha no kudakoresha amazi. Kongeramo imishinga ikoreshwa muri sima ni ingirakamaro cyane mu ikoreshwa aho beto yitezweho kugira imbaraga nyinshi cyangwa ikagira ibihe byinshi byo kwaguka no guhindagurika.
Kimwe mu byiza by'ingenzi bya kole za RDP polymer ni imiterere yazo myiza yo guhuza. Ibikoresho bya RDP polymer bigizwe n'ibintu bikoreshwa mu buvuzi bibafasha gufatana cyane n'uduce duto n'ibindi bice biri mu mvange ya beto. Ibi bituma matrix ya beto ikomera kandi iramba, ikarinda kwangirika kw'ingufu zo hanze nko gukonjesha no gushonga, kwangirika no gukomereka.
Indi nyungu y'ibikoresho bya RDP polymer ni ubushobozi bwabyo bwo kongera ubushobozi bwo kuvanga sima. Ibikoresho gakondo bya sima akenshi biracikagurika kandi bishobora kwangirika iyo bihuye n'ubushyuhe bwinshi cyangwa impinduka z'ubushyuhe. Ibikoresho bya RDP polymer bishobora guhindurwa kugira ngo bikore uburyo butandukanye bwo koroha, bigatuma imvange ya sima ibasha kwihanganira ubu buryo bworoshye idacikagurika. Uku kwiyongera kw'ubushobozi bwo koroha bigabanya kandi ibyago byo kwangirika cyangwa ubundi buryo bwo kwangirika mu gihe cyo kubaka cyangwa gukoresha.
Uretse kuba biramba kandi bikoroha, kole za RDP polymer nazo zirinda ubushuhe cyane. Inyubako za beto zihura n'amazi cyangwa ubushuhe igihe kirekire zishobora kugira ibibazo bitandukanye, birimo kwangirika, gushwanyagurika no kwangirika. Insinga za RDP polymer zirimo ibintu birwanya ubushuhe bifasha mu kwirukana ubushuhe, bikagabanya ibyago byo guhura n'ibi bibazo no kunoza imikorere y'inyubako za beto mu gihe kirekire.
Gukoresha kole za RDP polymer nabyo ni byiza ku bidukikije. Bitandukanye n'imvange gakondo ya sima, isanzwe ikenera sima nyinshi ya Portland, isoko rikomeye ry'ibyuka bihumanya ikirere, imvange za RDP polymer zishobora gukoresha ingano nto kugira ngo zigere ku rwego rumwe rw'imikorere. Ibi bigabanya karuboni mu mvange ya sima kandi bigafasha kugabanya ingaruka z'ubwubatsi ku bidukikije.
Nubwo hari ibyiza byinshi bifite, hari imbogamizi zimwe na zimwe zijyanye no gukoresha ibikoresho bya RDP polymer bifunga muri beto. Imwe mu mbogamizi zikomeye ni ugusuzuma neza ingano n'uburyo ibikoresho bya polymer bifunga kugira ngo habeho imikorere myiza. Kugira ibikoresho bike bifunga bituma bigabanuka kandi biramba, mu gihe gukoresha ibikoresho byinshi bifunga bituma imbaraga zigabanuka kandi bigatuma ubushobozi bwo gukora bugabanuka. Kubwibyo, ni ngombwa gukorana n'umucuruzi w'inararibonye usobanukiwe imiterere y'ibikoresho bya RDP polymer bifunga kandi ashobora gufasha mu kunoza ikoreshwa ryabyo mu bikorwa byihariye.
Hari ibyiza byinshi byo gukoresha ibikoresho bya RDP polymer binder muri beto ifite imikorere myiza. Byongera kuramba no koroha kw'imvange ya beto, byongera ubushobozi bwayo bwo guhangana n'ubushuhe, kandi bigira ingaruka nke ku bidukikije ugereranyije n'imvange gakondo ya beto. Nubwo ikoreshwa ryabyo ritanga imbogamizi zimwe na zimwe, kubivanga no kubivanga neza bishobora gutanga umusaruro mwiza kandi bigatera gukora inyubako zikomeye kandi zirambye za beto. Kole za RDP polymer ni amahitamo meza ku bashaka kubaka inyubako za beto zishobora kwihanganira imimerere mibi kandi zigatanga umusaruro wizewe uko igihe kigenda gihita.
