Ukuguqulwa kokuqukethwe kwe-latex powder kunethonya elisobala emandleni aguquguqukayo e-polymer mortar. Lapho okuqukethwe kwe-latex powder kungu-3%, 6% no-10%, amandla okuguquguquka kwe-fly ash-metakaolin geopolymer mortar anganyuswa ngo-1.8, 1.9 kanye nezikhathi ezingu-2.9 ngokulandelana. Ikhono le-fly ash-metakaolin geopolymer mortar ukumelana nokuguqulwa liyakhula ngokunyuka kokuqukethwe kwe-latex powder. Lapho okuqukethwe kwe-latex powder kungu-3%, 6% no-10%, ukuqina okuguquguqukayo kwe-fly ash-metakaolin geopolymer kukhuphuka ngo-0.6, 1.5 kanye nezikhathi ezingu-2.2, ngokulandelana.
I-Latex powder ithuthukisa kakhulu amandla okuguquguquka kanye nokubopha okuqinile kodaka lukasimende, ngaleyo ndlela ithuthukise ukuguquguquka kodaka lukasimende futhi ikhulise amandla okubopha okuqinile kwendawo yokuxhumanisa udaka lukasimende-ukhonkolo kanye nezinhlelo zebhodi likasimende-EPS.
Uma isilinganiso se-poly-ash singu-0.3-0.4, ukwelulwa ngesikhathi sekhefu lodaka lukasimende olushintshiwe nge-polymer kugxuma kusuka ngaphansi kuka-0.5% kuya cishe ku-20%, ukuze impahla ishintshe ukusuka ekuqineni kuya ekuguquguqukeni, futhi ikhulise inani. ye-polymer ingathola ukuguquguquka okuhle kakhulu.
Ukwandisa inani le-latex powder odakeni kungathuthukisa ukuguquguquka. Uma okuqukethwe kwe-polymer cishe ku-15%, ukuguquguquka kodaka kushintsha kakhulu. Uma okuqukethwe kuphakeme kunalokhu okuqukethwe, ukuguquguquka kodaka kukhula kakhulu ngokunyuka kokuqukethwe kwe-latex powder.
Ngokusebenzisa ikhono lokuqhekeka kwebhuloho kanye nokuhlolwa kokuguquguquka okuguquguqukayo, kwatholakala ukuthi ngokwanda kokuqukethwe kwempushana ye-latex (kusuka ku-10% kuya ku-16%), ukuguquguquka kodaka kancane kancane kwanda, kanye nekhono lokuqhekeka kwebhuloho eliguqukayo (7d) lenyuka lisuka ku-0.19mm laya ku- 0.67 mm, kuyilapho ukuwohloka kwezinhlangothi (28d) kukhuphuke kusuka ku-2.5mm kuya ku-6.3mm. Ngesikhathi esifanayo, kuphinde kwatholakala ukuthi ukwanda kokuqukethwe kwe-latex powder kungakhuphula kancane ukucindezela kwe-anti-seepage kwendawo yangemuva yodaka, futhi kunganciphisa ukumuncwa kwamanzi odongeni. Ngokukhula kokuqukethwe kwe-latex powder, ukumelana namanzi isikhathi eside kodaka kwehla kancane kancane. Lapho okuqukethwe kwe-latex powder kulungiswa ku-10% -16%, i-slurry esekelwe kusimende eguquliwe ayikwazi nje ukuthola ukuguquguquka okuhle, kodwa futhi ibe nokuphikiswa kwamanzi okuhle kakhulu isikhathi eside.
