Makampani opanga pansi amawononga pafupifupi US $ 2.4 biliyoni pachaka kukonzanso zofooka za pansi zomwe zimachitika chifukwa cha chinyezi. Ngakhale zili choncho, mankhwala ambiri amatha kuthetsa zizindikiro za kulephera kwa chinyezi, osati zomwe zimayambitsa.
Chifukwa chachikulu cha kulephera kwapansi ndi chinyezi chochokera ku konkire. Ngakhale kuti ntchito yomangayi yazindikira kuti chinyezi chapansi panthaka ndichomwe chimayambitsa kulephera kwapansi, ichi ndi chizindikiro cha vuto lozama kwambiri. Pothana ndi chizindikiro ichi popanda kuthana ndi zomwe zimayambitsa, ogwira nawo ntchito akukumana ndi chiopsezo chopitirizabe kulephera kwapansi. M’zaka makumi angapo zapitazi, makampani omanga ayesetsa mobwerezabwereza kuti athetse vutoli, koma sanachite bwino. Muyezo wamakono wokonza zophimba slab ndi zomatira zapadera kapena epoxy resin zimangothetsa vuto la chinyezi chapamwamba ndikunyalanyaza gwero la konkriti permeability.
Kuti mumvetse bwino lingaliro ili, choyamba muyenera kumvetsetsa sayansi yoyambira ya konkriti yokha. Konkire ndi kuphatikiza kosinthika kwa zigawo zomwe zimaphatikizana kupanga chothandizira. Iyi ndi njira imodzi yokha yomwe imayambira madzi akawonjezedwa pazowuma. Zomwe zimachitika pang'onopang'ono ndipo zimatha kusinthidwa ndi zikoka zakunja (monga mlengalenga ndi njira zomaliza) nthawi iliyonse munjira. Kusintha kulikonse kungakhale ndi zotsatira zoipa, zandale kapena zabwino pa permeability. Pofuna kupewa izi kuti zisalephereke, njira imodzi yokha ya mankhwala ochiritsa konkire iyenera kuyendetsedwa. Zogulitsa zomwe zimatha kuwongolera momwe mankhwalawa amachitira, kukhathamiritsa konkriti, ndikuchotsa kupindika pansi komanso kusweka kokhudzana ndi machiritso.
Kutengera zomwe zapezazi, MasterSpec ndi BSD SpecLink adapanga gulu latsopano mu Gawo 3, lodziwika ngati kuchiritsa ndi kusindikiza, kuchepetsa kutulutsa chinyezi, komanso kulowa. Gulu latsopanoli la Gawo 3 litha kupezeka mu gawo la MasterSpec 2.7 ndi pa intaneti BSD SpecLink. Kuti muyenerere gululi, zogulitsa ziyenera kuyesedwa ndi labotale yodziyimira pawokha yachitatu malinga ndi njira zoyeserera za ASTM C39. Gululi lisasokonezedwe ndi kaphatikizidwe kamene kamatulutsa chinyezi kamene kamapanga filimu, kamene kamayambitsa mizere yowonjezera yomangirira ndipo simakwaniritsa miyezo yapamwamba yamagulu a permeation.
Zogulitsa zomwe zili m'gulu latsopanoli sizimatsata njira yokonzera. (Mtengo wam'mbuyomu wamtengo wapatali unali osachepera $ 4.50 / square foot.) M'malo mwake, pogwiritsa ntchito kupopera kosavuta, machitidwewa amatha kulowa mkati mwa konkire, kuchepetsa matrix a capillary, ndi kuchepetsa kutsekemera. Kuchepa kwapakati kumasokoneza njira yomwe imalola kuti chinyezi, chinyezi, ndi alkalinity zinyamulidwe pamwamba pa slab kapena wosanjikiza womangira. Mwa kungochotsa kulephera kwapansi kwathunthu, mosasamala kanthu za mtundu wapansi kapena zomatira, izi zimachotsa mtengo wokwera wa kukonzanso kokhudzana ndi chinyezi chifukwa cha kulephera kwapansi.
Chinthu chimodzi m'gulu latsopanoli ndi SINAK's VC-5, yomwe imayang'anira permeability ndikuchotsa kulephera kwapansi chifukwa cha chinyezi, chinyezi, ndi alkalinity yotulutsidwa ndi konkire. VC-5 imapereka chitetezo chokhazikika pa tsiku la kuyika konkire, kuchotsa ndalama zokonzanso, ndikusintha machiritso, kusindikiza, ndi kuwongolera chinyezi. Pansi pa 1 USD/m². Poyerekeza ndi mtengo wanthawi zonse wokonza, ft VC-5 imatha kupulumutsa ndalama zoposa 78%. Polumikiza bajeti za Gawo 3 ndi Gawo 9, dongosololi limachotsa maudindo powongolera kulumikizana kwa polojekiti komanso kukonzekera bwino. Pakadali pano, SIAK ndi kampani yokhayo yomwe yapanga matekinoloje omwe amaposa miyezo yapamwamba kwambiri yamakampani pankhaniyi.
Kuti mumve zambiri za momwe mungapewere zovuta za chinyezi cha slab ndikuchotsa zolakwika zosefukira, chonde pitani www.sinak.com.
Zomwe zimathandizidwa ndi gawo lolipidwa lapadera momwe makampani opanga makampani amapereka zinthu zapamwamba kwambiri, zomwe sizili zamalonda pamitu yomwe ili yosangalatsa kwa omvera azomangamanga. Zonse zomwe zimathandizidwa zimaperekedwa ndi makampani otsatsa. Kodi mukufuna kutenga nawo mbali pagawo lathu lothandizira? Chonde funsani woyimira kwanuko.
