Shanduko ye latex poda yemukati ine pesvedzero iri pachena pakusimba kwesimba repolymer mortar.Kana zviri mukati me latex powder iri 3%, 6% uye 10%, simba rekushandura refly ash-metakaolin geopolymer mortar inogona kuwedzerwa ne 1.8, 1.9 uye 2.9 nguva.Kugona kwenhunzi ash-metakaolin geopolymer mortar kuramba deformation inowedzera nekuwedzera kwelatex powder content.Kana zviri mukati me latex powder iri 3%, 6% uye 10%, flexural toughness ye fly ash-metakaolin geopolymer inowedzera ne 0.6, 1.5 uye 2.2 nguva, maererano.
Latex poda inovandudza zvakanyanya kusimba uye kusungirira kusimba kwesamende dhaka, nekudaro inovandudza kuchinjika kwesamende dhaka uye kuwedzera kusungirira kusimba kwenzvimbo yekubatanidza simende dhaka-kongiri uye simende dhaka-EPS bhodhi masisitimu.
Kana iyo poly-ash reshiyo iri 0.3-0.4, kureba pakuputsika kwepolymer-yakagadziridzwa simende dhaka inosvetuka kubva pasi pe 0.5% kusvika kunosvika 20%, kuitira kuti zvinhu izvi zvishanduke kubva mukuoma kuenda kune kuchinjika, uye kuwedzera kuwedzera huwandu. yepolymer inogona kuwana Yakanyanya kunaka kuchinjika.
Kuwedzera huwandu hwe latex powder mudhaka inogona kuvandudza kushanduka.Kana iyo polymer yemukati inenge 15%, kuchinjika kwedhaka kunochinja zvakanyanya.Kana zvinyorwa zvakakwirira kudarika izvi, kushanduka kwevhu kunowedzera zvakanyanya nekuwedzera kwe latex powder content.
Kuburikidza nekuvhara kugona kwekupwanya uye kuchinjika deformation bvunzo, zvakaonekwa kuti nekuwedzera kwelatex poda yemukati (kubva pa10% kusvika 16%), kuchinjika kwedhaka kwakawedzera zvishoma nezvishoma, uye simba rekuvhara bhiriji kugona (7d) rakawedzera kubva pa0.19mm kuenda 0.67 mm, nepo lateral deformation (28d) yakawedzera kubva 2.5mm kusvika 6.3mm.Panguva imwecheteyo, yakawanikwawo kuti kuwedzera kwe latex powder content kunogona kuwedzera zvishoma anti-seepage pressure yemusana wevhu, uye inogona kuderedza kunwa kwemvura kwedhaka.Nekuwedzera kwe latex powder content, iyo yenguva refu yekudzivirira mvura yedhaka zvishoma nezvishoma yakaderera.Kana zviri mukati me latex poda yakagadziridzwa kusvika 10% -16%, iyo yakagadziridzwa simende-based slurry haingogone kuwana yakanaka kuchinjika, asiwo ine yakanakisa yenguva refu yekudzivirira mvura.
Nekuwedzera kwe latex powder content, kuwirirana uye kuchengetwa kwemvura kwedhaka zviri pachena kunovandudzwa, uye kushanda kwekushanda kunogadziriswa.Kana huwandu hwe latex powder hunosvika 2.5%, kushanda kwevhu kunogona kuzadzisa zvizere zvinodiwa zvekuvaka.Nhamba ye latex powder haifaniri kunge yakanyanyisa, iyo haingoiti chete EPS insulation mortar zvakare viscous uye ine yakaderera fluidity, iyo isingagadzirisi kuvaka, asiwo inowedzera mari yedhaka.
