Kukana Frost ndi madzi kukana konkire. Kalasi konkire chisanu kukana ndi madzi kukana. Konkire admixtures kwa watertight

Ngakhale zosiyanasiyana zipangizo zamakono nyumba konkire akupitiriza kukhala ndi udindo waukulu pakati kupikisana mungachite, chifukwa ali ndi makhalidwe ofunika kwambiri monga kwake, kudalirika ndi durability. Ndi chofunika kwambiri njira polenga maziko, zomangamanga, pulasitala ndi ntchito zina nyumbayi.

Madzi kukana konkire, komanso umatha kupirira mavuto nyengo, ndi makhalidwe waukulu kuonetsetsa moyo utumiki yaitali mankhwala itatha. akwaniritsa zimenezi ziri zofunikira posankha mtundu wa zinthu nyumbayi.

Konkire, chisanu kukana ndi madzi kukana amene ali pa msinkhu mkulu, ndi chitsimikizo cha ubwino ndi yabwino ntchito ntchito za kamangidwe iliyonse. Pansi katundu awa amatanthauza mphamvu ya mankhwala konkire kupirira mavuto zochitika zachilengedwe monga chinyezi, madzi ndi kutentha negative.

Panopa, pali sukulu zosiyanasiyana konkire chisanu kukana ndi madzi kukana, yodziwika ndi quality, mtengo ndi mphamvu sayansi. Gawo Izi zimathandiza kusankha zinthu optimally oyenera nyumba, anafuna kuti ntchito m'malo osiyanasiyana.

Stamps konkire kumatira

Malinga mlingo wa madzi kukana, konkire lagawidwa zopangidwa khumi lalikulu (GOST 26633). Iwo amadziŵika ndi kalata W Latin ndi makamaka phindu digito zimasonyeza kuthamanga pazipita madzi, amene akumutsutsa konkire mayeso nyemba mawonekedwe cylindrical wa masentimita 15 kutalika pa kuyezetsa wapadera.

Khama la madzi kukana konkire ikuchitika zizindikiro mwachindunji ndi zotsalira za mogwirizana ake ndi madzi. Direct zizindikiro ndi kalasi konkire ndi mlingo wake kusefera, ndipo mozungulira - muyeso wa mayamwidwe madzi ndi madzi simenti chiŵerengero ndi kulemera.

Mseri ndi malonda mchitidwe yomanga kuphunzira madzi kukana konkire, kulabadira mtundu wake, ndi muyezo zina ndi zofunika makamaka kupanga zomangira.

Mbali khalidwe la zopangidwa konkire ntchito madzi

Posankha mtundu konkire chofunika kuchita mitundu ina ya ntchito yomanga motsogozedwa ndi manambala index amene atsata makalata a W, amakhala mlingo wa mogwirizana kwa zinthu ndi chinyontho ndi madzi. Mwachitsanzo, kulimbikira wotsikitsitsa konkire, choncho otsika quality, kalasi W2. njira pa maziko awa osavomerezeka ntchito ngakhale mu mapangidwe ndi pamlingo wochepa chinyezi.

Normal digiri ya permeability auzidwa W4 mtundu. Izi zikutanthauza kuti zikuchokera nazo sachedwa kutengera chokwanira cha madzi, kotero zake ntchito n'chotheka malinga kumatira wabwino.
Pa udindo kutsatira khalidwe lonse mukalembe W6, amene amakhala ndi permeability otsika. Amenewa amanena za formulations konkire khalidwe sing'anga ndi mtengo wochepa gulu, ndipo ichi ndi chifukwa kutchuka ntchito yomanga.

Konkire chizindikiro W8 ali ndi permeability otsika chifukwa zimatenga chinyontho mu kuchuluka kwa okha 4.2% ya kulemera kwake. Ndi bwino ndiponso zodula njira, poyerekeza ndi chizindikiro W6.

Adamtsata kalasi konkire ndi zolozera 10, 12, 14, 16, 18 ndi 20. The apamwamba phindu n'zosangalatsa kumva, m'munsi permeability zakuthupi. Malinga ndi gulu ili, kwambiri madzi konkire mtundu ndi W20, koma si kawirikawiri amagwiritsidwa ntchito chifukwa cha mtengo ndi mkulu.

Othandiza ntchito zopangidwa ena konkire pa madzi kukana

Konkire zosiyanasiyana ayenera Wosankhidwa malingana opaleshoni zinthu zinthu. Mwachitsanzo, chifukwa kuthira maziko loyenereradi W8 chizindikiro dongosolo anapereka kumatira zina. Kupaka pulasitala makoma kubala sukulu konkire W8-w14. Komabe, chirichonse ndithu yonyowa pokonza ndi kuzizira zipinda madzi kukana konkire ndi kukhala ndi pazipita, choncho tikulimbikitsidwa kugwiritsa ntchito apamwamba zothetsera khalidwe amafuna chithandizo zina mwa makoma ndi basecoat wapadera.

Pakuti khalidwe ndi cholimba Mpanda wa kunja, kuthira malo uchikumbe ndi mayendedwe kugwiritsa ntchito simenti ndi mfundo pazipita madzi kukana, monga madera awa nthawi zonse poyera kuti mavuto nyengo kunja.

Zina konkire kumatira manja awo

Kufunika ntchito apamwamba zosakaniza konkire kupanga zinthu zosiyanasiyana kapena zinthu zace zoonekeratu, koma pamafunika chidwi ndalama ndalama chifukwa cha kukwera mtengo kwa zomangira. Koma bwanji ngati kumanga bajeti yochepa, ndi kuphwanya ndondomeko ndi zosavomerezeka? Yankho lake ndi losavuta: mungagwiritse ntchito kukondera, ndicho kuonjezera madzi kukana konkire yekha.

Masiku ano, pali ogwira njira zingapo kuonjezera kulimbikira konkire Kusakaniza ndi madzi, koma kutchuka aakulu amene amadza awiri a iwo kuchotsa shrinkage konkire ndi zotsatira osakhalitsa pa zikuchokera konkire.

The liquidation ndondomeko ya shrinkage konkire

Concretes otsika ndi sukulu pakati ndi mokwanira zipangizo porous mosavuta kuyamwa chinyontho. Mundawu zoipa ndi nakweza mu ndondomeko ya shrinkage pa solidification wa njira. Choncho, kusintha khalidwe ndi madzi kukana konkire chingapezeke mwa kuchepetsa mlingo wa shrinkage.

Kukwaniritsa chimene mukufuna kudzakuthandizani njira Integrated:

1. Inu muyenera kugwiritsa ntchito yapadera admixtures konkire madzi kukana. Mfundo ntchito ndi pa solidification wa njira iwo amapanga filimu zoteteza, kuteteza shrinkage ake. Today kumsika amapereka zosiyanasiyana zina konkire pa madzi, ndipo ngakhale ntchito patsogolo pawo pali umodzi, koma zonse njira limodzi makhalidwe ake, kotero musanagule azitha kuwerenga malangizo a opanga galimotoyo.
2. Kuwonjezera anawonjezera kuti konkire kumatira zina zapadera, izo analimbikitsanso kuthira madzi. Ndondomeko anachita kwa masiku anayi, ndi imeneyi ya maola 4. Kenako, dongosolo konkire ziyenera kuyanikidwa zinthu zachilengedwe.
3. Ndi evaporation mofulumira chinyezi kuchokera yankho pa solidification likugwiritsidwanso zoipa shrinkage. Yobwerera ndondomeko imeneyi, pambuyo kuthira dongosolo konkire ziyenera yomweyo yokutidwa ndi filimu wapadera, amene anapanga ndi condensation popewa shrinkage ndi kulimbikitsa kuchuluka kwake konkire. Kubisa njira kuti si kukhudza kukhuta. Pamodzi m'mbali mwa kusiya mipata kochepa kwa mpweya mpweya wabwino.

zotsatira osakhalitsa pa kapangidwe konkire

Njira imeneyi ndi kupereka njira youma "wokhwima" kwa nthawi zina. Lamulo yeniyeni apa ndi kugwilizana ndi zinthu moyenera yosungirako. osakaniza ayenera kukhala mu chipinda ofunda mdima ndi pansi chinyezi nthawi zonse. Choncho patapita miyezi isanu ndi madzi kukana ake zingawonjezere ndi kangapo.

chisanu kukana konkire

Mu chizindikiro izi zikutanthauza luso zosakaniza konkire kusunga katundu wawo thupi ndi makina mu zikhalidwe za yozizira koopsa mobwerezabwereza ndi thawing. Mbali imeneyi n'chofunikira yaikulu kusankha konkire omanga zipilalapo mlatho, airfield ndi msewu pavements, matamanda a madzi, nyumba ndi maofesi ena unathandizira pa M'madera a zitunda pakati ndi kumpoto.

Khama la chisanu kukana konkire ikuchitika ndi mayesero zasayansi ntchito njira ziwiri: m'munsi ndi inapita patsogolo. Ngati zotsatira za maphunziro amasiyana, tidzakambirana kwa deta yomalizayi analandira ntchito njira zofunika.

Investigation kukaniza konkire kuti otsika kutentha

Mayesero ikuchitika ntchito zikuluzikulu ndi ulamuliro zitsanzo, amene amapangidwa kuchokera ku sukulu zosiyanasiyana za kumatira konkire kukayezetsa siriyo. Control akusowekapo konkire ntchito kudziwa mphamvu zawo compressive. Ndondomeko ikuchitika pamaso pa mayesero zitsanzo zofunika kuti adzakhala pansi amaundana-m'firiji pamtunda mu modes osiyanasiyana machulukitsidwe, amene kutenga malo mu zinthu zachilengedwe nyengo.

Mwachitsanzo:

• pamaso pa mlingo wokweretsa pansi;
• mu thawing nyengo ya Madzi oundana ndi;
• atadziŵa mpweya;
• pakalibe machulukitsidwe nthawi, pamene simenti ndi kutetezedwa pansi ndi mpweya.

Gulu mlingo wa simenti chisanu kukana ndi zopangidwa

Malinga atsopano Nsanja ya Standard, chisanu kukana konkire mtundu amaimira Latin kalata F. Izi mtengo amadziwika ndi pazipita angapo amaundana / m'firiji pamtunda m'zinthu, kukamaomba wina ntchito zitsanzo okalamba mu mawu a kuchepetsa wa kwamakokedwe mphamvu ndi kuchepetsa kulemera kwa zinthu pa wake wapatali, anapereka malangizo wogwila mfundo.

Pofuna kudziwa mlingo wa kukana chisanu konkire ntchito ndi zizindikiro digito ku 25 1000. The apamwamba phindu, ndi apamwamba khalidwe ndi kudalilika kwa nkhaniyo.

Malamulo kusankha zosakaniza konkire

Posankha kalasi chofunika zosakaniza konkire pa katundu chisanu zosagwira ayenera idzachitika kutenga nkhani makhalidwe nyengo ya m'deralo, komanso chiwerengero cha yozizira koopsa ndi thawing m'zinthu pa nyengo yozizira. Onani kuti kulimbikira kwambiri chisanu ndi concretes ndi osalimba mkulu.
