Mataki na 1: gwada alkalinity na siminti

Gwada ƙimar pH na siminti da aka tsara, kuma yi amfani da pH, pH mita ko pH alkalami don gwadawa. Za a iya amfani da sakamakon gwajin don tantancewa da farko: ko adadin alkali mai narkewa a cikin siminti babba ne ko karami; ko admixture a cikin siminti ne acidic ko inert abu kamar dutse foda, wanda ya sa pH darajar low.

Mataki na 2: bincike

Sashin farko na binciken shine samun sakamakon binciken clinker na siminti. Yi lissafin abubuwan da ke cikin ma'adanai huɗu a cikin siminti: tricalcium aluminate C3A, tetracalcium aluminoferrite C4AF, tricalcium silicate C3S da dicalcium silicate C2S.

Sashi na biyu na bincike shi ne fahimtar irin abubuwan da ake hadawa a lokacin da aka nika siminti da nawa ake karawa, wanda hakan ke matukar taimakawa wajen nazarin abubuwan da ke haifar da zubar da jini na kankare da kuma lokacin da ba a saba gani ba (da tsayi, gajere).

Kashi na uku na binciken shine fahimtar iri-iri da kuma ingancin abubuwan da aka haɗa da kankare.

Mataki na 3: Nemo cikakken ƙimar sashi

Nemo cikakken ƙimar madaidaicin mai rage ruwa da ake amfani da shi don wannan siminti. Idan an haɗu biyu ko fiye da manyan masu rage ruwa masu inganci, nemo madaidaicin madaidaicin sashi ta gwajin manna siminti gwargwadon adadin adadin. Matsakaicin mafi kusancin adadin mai rage ruwa mai inganci shine zuwa cikakken adadin siminti, mafi sauƙin shine samun ingantaccen daidaitawa.

Mataki 4: Daidaita matakin filastik na clinker zuwa kewayon da ya dace

Daidaita matakin alkali sulfation a cikin siminti, wato, matakin filastik na clinker zuwa kewayon da ya dace. Ƙididdigar ƙididdiga don ƙimar SD na darajar filastik na clinker shine: SD = SO3 / (1.292Na2O + 0.85K2O) An jera ƙimar abun ciki na kowane ɓangaren a cikin binciken clinker. Matsakaicin ƙimar SD shine 40% zuwa 200%. Idan ya yi ƙasa sosai, yana nufin cewa akwai ƙarancin sulfur trioxide. Ya kamata a ƙara ɗan ƙaramin gishiri mai ɗauke da sulfur kamar sodium sulfate a cikin haɗin gwiwa. Idan ya yi tsayi da yawa, yana nufin cewa kwayoyin sun fi girma, wato, akwai ƙarin sulfur trioxide. Ƙimar pH na admixture ya kamata a ƙara dan kadan, kamar sodium carbonate, caustic soda, da dai sauransu.

Mataki na 5: Gwada-haɗa haɗaɗɗen haɗakarwa da gano nau'in da adadin adadin wakilan saitin

Lokacin da ingancin yashi ba shi da kyau, kamar babban abun ciki na laka, ko kuma lokacin da aka yi amfani da duk yashi na wucin gadi da yashi superfine don haɗa kankare, bayan gwajin slurry na yanar gizo ya sami sakamako mai gamsarwa, ya zama dole a ci gaba da yin gwajin turmi don ƙara daidaita daidaitawa tare da admixture.

Mataki na 6: Gwajin Kankare Don gwajin kankare, adadin cakuda bai kamata ya zama ƙasa da lita 10 ba.

Ko da net slurry da aka gyara da kyau, shi zai iya har yanzu ba saduwa da tsammanin a cikin kankare; idan net slurry ba a daidaita shi da kyau, siminti na iya samun matsala mafi girma.Bayan ƙananan gwajin gwaji ya yi nasara, wani lokacin babban adadin yana buƙatar maimaitawa, kamar lita 25 zuwa lita 45, saboda sakamakon zai iya zama dan kadan daban-daban.
