Magwero a matope ndi osiyana, ndipo zigawo zawo ndizosiyananso. Matope a mchenga wa sinkrete ndi miyala yogawika imagawidwa m'magulu atatu: ufa wautali, dongo, ndi carcium carbonate. Pakati pawo, ufa ufa ndi tinthu tating'onoting'ono tomwe timapanga mumchenga wopangidwa ndi tinthu tating'onoting'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tinthu tating'ono tosakwana 75 μm. Ndiwo mwala womwewo monga mwala wopangidwa ndipo uli ndi mawonekedwe ofananawo. Gawo lalikulu ndi CACO3, yomwe ndi gawo la mawonekedwe amchenga opangidwa.

Nthawi zambiri zimakhulupirira kuti chifukwa chachikulu chomwe matope mumakhudzira zosakanizidwa ndi lignosulfonate ndi madzi ochepetsera matope ndi mpikisano wa matope pakati pa matope ndi simenti. Palibe kufotokoza kogwirizana pa mfundo yogwira ntchito matope ndi polycatboxylic acid acid mankhwala. Ophunzira ena amakhulupirira kuti mfundo yogwira ntchito yamatope ndi kuwongolera madzi kumafanana ndi simenti. Wothandizira madzi akupumula amadziletsa pamtunda wa simenti kapena matope ufa wokhala ndi magulu anionic. Kusiyanaku ndikuti kuchuluka kwa adsorption wa mankhwala osokoneza madzi ndi matope ndi akulu kwambiri kuposa simenti. Nthawi yomweyo, malo apamwamba kwambiri ndi mawonekedwe a michere otayika amatenga madzi ambiri ndikuchepetsa madzi aulere pabwino, omwe amakhudzanso ntchito yomanga konkriti.
(2) Zotsatira za mchere wosiyanasiyana pamayendedwe ochepetsa madzi:
Kafukufuku akuwonetsa kuti matope a clayiy okha ndi kukula kwakukulu ndi mitundu yofunika kwambiri ndi manyowa amadzi kudzakhala ndi zofunika kwambiri pakugwira ntchito ndi zojambula pambuyo pake. Matope ofala omwe ali m'magulu amaphatikizapo Kaolin, anite ndi Monmorillonite. Mtundu womwewo wa mankhwalawo osokoneza madzi ali ndi zomveka zosiyanasiyana pamatope opanga matope, ndipo kusiyana kumeneku ndikofunikira kwambiri pakusankhidwa kwa mankhwala osokoneza bongo ndi chitukuko cha mankhwala osokoneza bongo.
(3) Zotsatira za matope ufa wokhala pamatango:
Kugwira ntchito konkriti sikungokhudza kupangika kwa konkriti, komanso kumakhudzanso zachilengedwe pambuyo pake. Kuchulukitsa kwa matope ufa ndi wosakhazikika, kufota mukauma ndikukulitsa mukanyowa. Monga momwe matope amakulira, kaya ndi polycaxylate madzi kapena mankhwala ochepetsa madzi kapena muyeso wogwiritsa ntchito madzi, umachepetsa kuchuluka kwa madzi, mphamvu, komanso kutsika kwa konkriti. Kugwa, etc., bweretsani kuwonongeka kwakukulu kwa konkriti. Nsanja ya National "(GB / T14684-2011) ikadakhala C30 kapena YourPage kapena Zofuna Zapadera, Maunda Pang'onopang'ono %, ndipo matope a matope sangapitirire 1.0%; Pamene mphamvu yotsikira ndi yocheperako c30, matope a matope sadzapitirira 5.0% ndi matope a matope sangapitirire 2.0%.
