Ready-Mix Mortar ndi chinthu chomangira chomwe chimapangidwa kuti chigwiritsidwe ntchito pomanga.Zimapangidwa ndi kusakaniza simenti, mchenga ndi madzi mosiyanasiyana, malingana ndi mphamvu zomwe zimafunidwa ndi kusasinthasintha kwa mankhwala omalizidwa.Kuphatikiza pazigawo zoyambira izi, matope osakaniza okonzeka amakhalanso ndi zinthu zingapo zomwe zimapangidwira kuti zithandizire komanso kukhazikika kwake.
Zowonjezera mankhwala ndi zinthu zomwe zimawonjezeredwa kuzinthu kuti ziwonjezere kapena kusintha mawonekedwe ake.Kwa matope osakaniza okonzeka, zowonjezerazi nthawi zambiri zimasankhidwa kuti athe kupititsa patsogolo ntchito, kufupikitsa nthawi yokhazikitsa, kuonjezera kusunga madzi, ndikuwonjezera mphamvu ndi kulimba kwa chinthu chomalizidwa.
M'nkhaniyi tiwona zina mwazowonjezera zamankhwala zomwe zimagwiritsidwa ntchito popanga matope okonzeka.
1.Kubweza
Ma retarders ndi gulu lazinthu zowonjezera zomwe zimagwiritsidwa ntchito kuchepetsa nthawi yoyika zinthu zopangidwa ndi simenti.Amagwira ntchito mwa kuchedwetsa kusintha kwa mankhwala komwe kumachitika simenti ikakumana ndi madzi, zomwe zimapatsa antchito nthawi yochulukirapo kuti amalize ntchitoyo matope asanayambe.
Ma retarders ndi othandiza makamaka nyengo yotentha kapena pogwira ntchito ndi dothi lambiri, lomwe mwina likhoza kukhazikika mwachangu.Nthawi zambiri amawonjezeredwa kusakaniza matope pamlingo wa 0.1% mpaka 0.5% wa simenti.
2. Pulasitiki
Plasticizers ndi mtundu wina wa zowonjezera mankhwala omwe amagwiritsidwa ntchito mumatope osakaniza okonzeka.Cholinga chawo ndi kuchepetsa kukhuthala kwa matope, kuti zikhale zosavuta kuzigwira ndikugwiritsa ntchito.
Mapulasitiki nthawi zambiri amawonjezeredwa kusakaniza kwamatope pamlingo wa 0.1% mpaka 0.5% wa simenti.Amapangitsa kuti matope aziyenda bwino, kupangitsa kuti zikhale zosavuta kufalikira ndikukwaniritsa kumaliza kofanana.
3. Wosunga madzi
Madzi osungira madzi ndi mtundu wa zowonjezera za mankhwala zomwe zimapangitsa kuti matope asunge madzi.Cholinga chawo ndi kuchepetsa kuchuluka kwa madzi omwe amatayika chifukwa cha nthunzi panthawi yochiritsa, zomwe zimathandiza kupewa kuchepa ndi kusweka.
Osungira madzi nthawi zambiri amawonjezeredwa kusakaniza kwamatope pamlingo wa 0.1% mpaka 0.2% wa simenti.Amapangitsa kuti matope azitha kugwira ntchito bwino, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito komanso kuti ikhale yosalala, yosalala.
4. Air-entraining wothandizira
Ma air-entraining agents amagwiritsidwa ntchito kuyambitsa tinthu ting'onoting'ono ta mpweya mumsanganizo wamatope.Ma thovuwa amakhala ngati ting'onoting'ono ting'onoting'ono tonyezimira, zomwe zimawonjezera kulimba ndi kuzizira kwa zinthu zomwe zamalizidwa.
Othandizira mpweya amawonjezeredwa kusakaniza kwamatope pamlingo wa 0.01% mpaka 0.5% wa simenti.Amatha kupititsa patsogolo ntchito ya matope ndikupangitsa kuti ikhale yosavuta kugwiritsa ntchito, makamaka pogwira ntchito ndi magulu ovuta.
5. Accelerator
Ma Accelerator ndi zowonjezera zomwe zimagwiritsidwa ntchito kufulumizitsa nthawi yoyika matope.Amagwiritsidwa ntchito m'nyengo yozizira kapena pamene matope amafunika kumalizidwa mwamsanga.
Ma Accelerator nthawi zambiri amawonjezeredwa kusakaniza kwamatope pamlingo wa 0.1% mpaka 0.5% wa simenti.Zitha kuthandiza kuchepetsa nthawi yomwe matope amatha kuchira ndikukula bwino, zomwe ndizofunikira pa ntchito yomanga yomwe imatenga nthawi yayitali.
6. Wothandizira kwambiri kuchepetsa madzi
Superplasticizer ndi plasticizer yomwe imagwiritsidwa ntchito kupititsa patsogolo ntchito yamatope.Amagwira ntchito pomwaza tinthu tating'onoting'ono ta simenti mofanana kwambiri mumatope osakaniza, potero amawongolera mawonekedwe ake.
Ma superplasticizers nthawi zambiri amawonjezeredwa kusakaniza kwamatope pamlingo wa 0.1% mpaka 0.5% wa simenti.Amapangitsa kuti matope azitha kugwira ntchito bwino, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito komanso kuti ikhale yosalala, yosalala.
Ready-Mix Mortar ndi zida zomangira zodziwika bwino zomwe zimagwiritsidwa ntchito kwambiri pomanga zosiyanasiyana.Zimapangidwa ndi kusakaniza kwa simenti, mchenga ndi madzi, komanso mitundu yambiri ya mankhwala omwe amagwiritsidwa ntchito kuti apititse patsogolo ntchito yake komanso kupirira.
Zina mwazowonjezera zamankhwala zomwe zimagwiritsidwa ntchito mumatope osakanizidwa bwino ndi monga ma retarders, plasticizers, zosungira madzi, air intraining agents, accelerators ndi superplasticizers.Zowonjezera izi zimasankhidwa mosamala kuti zithandizire kukonza, kufupikitsa nthawi yoyika, kuonjezera kusunga madzi ndikuwonjezera mphamvu ndi kulimba kwa chinthu chomalizidwa.
Pomvetsetsa gawo la chowonjezera chilichonse chamankhwala, akatswiri omanga amatha kusankha mtundu woyenera wa matope osakanizika okonzekera pulojekiti yawo ndikuwonetsetsa kuti akukwaniritsa zofunikira zake komanso kulimba kwake.
