Karāhe muka alkali papanga mata matakei runga i te karaehe reo kawakore me te karaihe kore utupapanga muka, i hangaia e te maimoatanga whakakikorua alkali. He kaha te kaha o te hua, he pai te whakakapi, he pai te tutukitanga me te tuunga pai. Kei te whakamahia whānuitia i roto i te whakapakari pakitara, te whakamahana waiariki o waho o nga pakitara o waho, te parewai o te tuanui, me etahi atu hei utu mo te ciment, te kirihou, te parapara, te mapere, te mosaic me etahi atu mea pakitara, he mea pai rawa atu te hangarau i roto i te ahumahi hanga.
Ko te ōwehenga o te muka karaihe ātete alkali ki te kawakore noa me te reomuka karaihe alkalihe ona āhuatanga faahiahia: pai ātete alkali, kaha tensile tiketike me te waikura kaha ātete i roto i te sima me ētahi atu pāpāho alkali kaha. Ko te raima whakakaha muka (GRC) he rauemi whakakaha e kore e taea te whakakapi.
Ko te muka karaihe atete te alkali te rauemi taketake o te muka karaihe sima (GRC). Na te whakahohonutanga o te whakarereketanga o te pakitara me te whanaketanga ohaoha, kua tohatohahia te GRC ki nga panui pakitara o roto, o waho hoki, nga panui whakamaarama wera, nga panui awhi hau, nga huahua maara me nga whakairo toi, nga mahi a-iwi me etahi atu. Ko nga hua me nga waahanga he uaua ki te whakatutuki, kaore ranei e taea te whakarite ki te raima whakakaha ka taea te hanga. Ka taea te whakamahi mo te kore kawenga, te kawenga tuarua, nga waahanga hangahanga-waahanga, nga waahanga whakapaipai, nga mahi ahuwhenua me nga mahi kararehe me etahi atu waa.
Ko te mata o te muka karaehe alkali he mea hanga ki te reo alkali me te kawakore o te muka karaihe, ka tukatukahia i muri i te maimoatanga ki te kopa copolymer kiriaku. He kaha te kaha o te kakahu mata, he pai te alkali me te waikawa waikawa me te whakakii kaha ki te kapia. He ngawari te kopiri a Styrene, he pai te maro me te tuunga pai. Ko te nuinga o te waa ka whakamahia hei raima, he kirihou, he raima, he tuanui me nga taputapu whakapakari pakitara. Ko te nuinga o te waa e whakamahia ana mo te GRC precoating, paninga me te hanga miihini ranei, ina koa mo te hanga i runga i te waahi o te miihini whakaahuru taiepa o waho.
