I-latex powder ehlakazeka kabusha ithuthukisa ukuguquguquka nokumelana nokuqhekeka kodaka

Ngemva kokwengeza i-latex powder ehlakazeka kabusha odakeni, isilinganiso se-fold-compression ratio kanye ne-tension-compression ratio of the mortar sithuthukiswa kakhulu, okubonisa ukuthi ukonakala kodaka kuncipha kakhulu futhi ukuqina kuthuthukiswa kakhulu, ukuze ukumelana nokuqhekeka udaka lwaba ngcono.

Impushana ye-latex ehlakazekile ilahlekelwa amanzi odakeni ukuze yenze ifilimu, engagcwalisi nje kuphela amaphutha nezimbotshana etsheni likasimende, kodwa futhi yenza imikhiqizo kasimende ye-hydration kanye nama-aggregates ahlangane ukuze kwakheke inethiwekhi yama-polymers angena ngaphakathi. I-modulus elastic of the mortar iphansi kunaleyo ye-mortar, ngakho-ke ukuqina kwe-mortar kuyancipha. Ukuguquguquka kodaka kukhulisa umkhawulo omkhulu wokuguquguquka lapho udaka lonakaliswa, futhi lungakwazi ukumunca amandla adingekayo ukuze kwandiswe amaphutha kanye nemifantu emincane ngokwezinga elikhulu, ukuze udaka lukwazi ukumelana nokucindezeleka okukhulu ngaphambi kokwehluleka. Ngaphezu kwalokho, ifilimu ye-polymer inomshini wokuzelula, futhi ifilimu ye-polymer inomsebenzi wejoyinti elinyakazayo kuhlaka lwamathambo oluqinile olwakhiwe odakeni ngemva kokufakwa kukasimende, okungaqinisekisa ukunwebeka nokuqina kohlaka lwamathambo oluqinile. Ubuso befilimu ye-polymer eyenziwe ebusweni bezinhlayiya zodaka bunezimbotshana, futhi ubuso be-pores bugcwele udaka, ukuze ukuhlushwa kokucindezeleka kuncishiswe, futhi kuzophumula ngaphandle kokulimala ngaphansi kwesenzo samandla angaphandle. Ithuthukisa ukuguquguquka nokunwebeka kodaka.
