Mene ne sinadaran na siminti?

Siminti - daya daga cikin muhimman kayan gini amfani a cikin wannan yanki tun lokacin da. Ciminti abun da ke ciki ya hada da wani yawan inorganic abubuwa wanda a lamba tare da ruwa ta samar da wata da ake kira bayani. Tare da kewayon takamaiman jiki halaye, a lokacin da bushe da mafita ta taurare.

Ciminti da aka samar a cikin hanyoyi da dama, amma mafi yawansu ba su ne biyu main amfani: bushe da rigar. Its samar - quite tsada da kuma makamashi-m tsari. A ake kira sludge a asalin siffan an ɗora Kwatancen cikin wani musamman tanda, sa'an nan sintering da clinker. A lokacin da masana'antu tsari da makera da aka ci gaba da juya su, don haka da cewa clinker shi ne gaba ɗaya gauraye. Wannan damar domin mafi kama cakuda kuma a ko'ina narke.

Ciminti abun da ke ciki hada da baƙin ƙarfe oxide. Shi yana da manya-manyan tasiri a kan] aukacin halin da sakamakon ciminti cakuda. Ciminti mafi ingancin - tare da baƙin ƙarfe oxide abun ciki na game da 10%. A wannan rabo oxides da mafi m sakamako a kan samuwar ma'adanai. Duk da haka, duk dole gwargwado, don haka ya kara yawan baƙin ƙarfe oxide a cikin ciminti an rage da kuma ta sauran quality.
Matsakaicin canja kudi an dauki 25% na baƙin ƙarfe oxide. Kamar yadda ka sani, sumunti kuma amfani da gina ko da samuwar zafi-resistant gine-gine da kuma Tsarin. A wannan yanayin, gaban baƙin ƙarfe oxides ne unacceptable. Bugu da kari, yawan baƙin ƙarfe yana da tasiri kai tsaye a kan siminti launi: da m shi ne, na ƙasa da yawan Additives. Gray sumunti, da bambanci, yana a cikin tsarin da mafi abun ciki na baƙin ƙarfe oxides.

Idan kara kwakkwance da sinadaran abun da ke ciki na sumunti, yana yiwuwa a gane shi da kuma alumina. A mafi girma adadin alumina dauke a cikin ciminti abun da ke ciki, ya ba shi Properties na zafi juriya. Qualitatively, ciminti abun ciki na abu ne game da 60%.

Bugu da kari a wadannan oxides, a ciminti abun da ke ciki ya hada da alli oxides, silicon, magnesium. Siminti kera suna yakar haka cewa su kayayyakin ba dauke da wani chromium oxide, wanda shi ne mai aiki karfe, kuma ya zo a cikin undesired sinadaran halayen.

Dangane da abun da ke ciki na sumunti, shi ne zuwa kashi iri da ciwon daban-daban jiki Properties: gipsoshlakovy, azumi saitin, ash, alumina, gipsoglinozemisty da kuma hana ruwa.

Ciminti abun da ke ciki don inganta halaye ƙara daban-daban aiki ma'adinai Additives. Su ne wucin gadi ko na halitta asali. Additives a ciminti ya ba shi daban-daban Properties: shi inganta Sannan ina da karuwa yawa, inganta scalability, rage shrinkage, plasticity da kuma canza yawa. Bugu da ƙari, Bugu da kari daga cikin wadannan abubuwa na taimaka karko da kuma karfin da ciminti slurries.

Additives a ciminti ba kawai amfani domin inganta wasu daga ta musamman jiki Properties, amma kuma canza, misali, launi. Domin wadannan dalilai, za ka iya amfani da wani yau da kullum da fenti.
