Loaʻa nā ʻano like ʻole a me nā ʻokoʻa o nā mea hoʻohui kemika no ka mortar a me ka ʻuala. ʻO ka mea nui kēia ma muli o ka hoʻohana ʻokoʻa ʻana o ka mortar a me ke kaila. Hoʻohana nui ʻia ʻo Concrete ma ke ʻano he mea hana, ʻoiai ʻo ka mortar ka mea hoʻopau a paʻa. Hiki ke hoʻokaʻawale ʻia nā mea hoʻohui kemika mortar e like me ka haku mele a me ka hoʻohana hana nui.
Hoʻokaʻawale ʻia e ka haku melemele
(1) Nā mea hoʻohui paʻakai paʻakai ʻole: e like me ka mea ikaika mua, antifreeze agent, accelerator, expansion agent, kala kala, waterproofing agent, etc.;
(2) Polymer surfactants: ʻO kēia ʻano admixture ka nui o nā surfactants, e like me nā plasticizers / water reducers, shrinkage reducers, defoamers, ea-entraining agents, emulsifiers, etc.;
(3) Resin polymers: e like me ka polymer emulsions, redispersible polymer powders, cellulose ethers, wai-soluble polymer material, etc.;
Hoʻokaʻawale ʻia e ka hana nui
(1) Admixtures e hoʻomaikaʻi i ka hana hana (rheological properties) o ka mortar hou, me nā plasticizers (nā mea hoʻemi wai), nā mea hoʻoheheʻe ea, nā mea mālama wai, a me nā tackifiers (viscosity regulators);
(2) Hoʻohui no ka hoʻoponopono ʻana i ka manawa hoʻonohonoho a me ka hana paʻakikī o ka mortar, me nā retarders, super retarders, accelerators, early strength agents, etc.;
(3) ʻO nā mea hoʻohui e hoʻomaikaʻi i ka lōʻihi o ka mortar, nā mea hoʻoheheʻe ea, nā mea hoʻoheheʻe wai, nā mea hoʻopiʻi rust, fungicides, alkali-aggregate reaction inhibitors;
(4) ʻO nā mea hoʻohui, nā mea hoʻonui a me nā mea hoʻohaʻahaʻa e hoʻomaikaʻi i ka paʻa o ka mortar;
(5) ʻO nā mea hoʻohui e hoʻomaikaʻi i nā waiwai mechanical o ka mortar, polymer emulsion, redispersible polymer pauka, cellulose ether, etc.;
(6) ʻO nā mea hoʻohui, nā kala, nā mea hoʻonani o ka ʻili, a me nā mea hoʻonani e hoʻomaikaʻi ai i nā mea hoʻonaninani o ka mortar;
(7) ʻO nā mea hoʻohui no ke kūkulu ʻana ma lalo o nā kūlana kūikawā, antifreeze, hoʻohui ponoʻī i ka mortar, etc.;
(8) ʻO nā mea ʻē aʻe, e like me nā fungicides, fibers, etc.;
ʻO ka ʻokoʻa koʻikoʻi ma waena o nā mea mortar a me nā mea palaki ʻo ia ka hoʻohana ʻia ʻana o ka mortar ma ke ʻano he paving a me ka mea hoʻopaʻa paʻa, a ʻo ia ka mea maʻamau he ʻano ʻāpana lahilahi ke hoʻohana ʻia, ʻoiai hoʻohana nui ʻia ka pāpaʻi ma ke ʻano he mea hoʻolālā, a nui hoʻi ka nui. No laila, ʻo nā koi no ka hana ʻana o ke kūkulu ʻana i ka ʻoihana kūʻai ʻoi aku ka paʻa, ka wai a me ka hiki ke hoʻopaʻa i ka fluidity. ʻO nā koi nui no ka hoʻohana ʻana i ka mortar he paʻa wai maikaʻi, cohesion a me thixotropy.
