Trass cement yog siv los ua tus neeg sawv cev los ua cov cements lossis mortars resistant ntau yam. Raws li kev npaj siv, Tras muaj cov khoom tshwj xeeb uas tuaj yeem siv tau zoo.
Composition
Trass cement mixs, raws li lub npe qhia, muaj qee yam khoom pov tseg. Tras yog ib txwm tshwm sim pozzolan, feem ntau ua los ntawm pob zeb volcanic. Pozzolans yog pob zeb uas muaj cov khoom nram qab no thiab yog li ntawd muaj zog reactivity:
- Silica
- Clay
- Organosilicon compounds
- Aluminium compounds
Silicic acid feem ntau muaj nyob rau hauv qhov ntau ntawm tsawg kawg yog 50 feem pua thiab yog lub ntsiab ntawm cov pob zeb. Trass ua kom muaj kev txhim kho hauv qee yam khoom hauv cov cement piv rau cov khoom sib xyaw classic. Tab sis nws tsis yog ib qho khoom siv hauv kev sib xyaw. Txhawm rau sib tov tras cement, lwm cov khoom xyaw tseem ceeb:
- burnt txiv qaub (hauv av)
- Sound
- optional: marl
Qhov txawv ntawm cement
Cov lus nug feem ntau tshwm sim raws li qhov txawv ntawm cov khib nyiab cement los ntawm cov cement classic. Txij li thaum cov cement sib tov yog ib hom "ntxiv" cov cement, cov lus nug no yuav tsum tau tshuaj xyuas kom meej ntxiv. Qhov sib txawv tseem ceeb tshaj plaws yog qhov nce ceev. Hauv cov cements, trass ua kom cov khoom sib tov muaj cov qauv denser. Txij li thaum Tras kuj tseem muaj qhov pores tsawg dua, ua ke nrog qhov ntom ntom, yuav luag kaw thiab elastic nto yog tsim thaum sib xyaw, uas tiv thaiv kev ntxhov siab tawg. Qhov no muaj qee qhov zoo uas cov cements classic tsis muaj:
- Nyob ntev
- waterproof
- tsawg tu siab heev
Qhov tseem ceeb tshaj, qhov dej tsis zoo yog qhov zoo dua. Ua tsaug rau qhov pore kaw, tsis muaj noo noo nkag mus rau hauv cov khoom, uas tsis tuaj yeem lav nrog cov cements qub. Cov cuab yeej no tseem ua kom ntseeg tau tias muaj kev puas tsuaj loj heev hauv lub caij ntuj no. Txij li thaum trass kuj muaj cov txiv qaub-txheej txheem, lub pob zeb tiv thaiv cov txiv qaub efflorescence, uas feem ntau yog teeb meem rau cov pob zeb sab nraum zoov. Txawm tias nyob rau hauv cov cheeb tsam uas muaj huab cua ntub, tras cement ua haujlwm zoo tiv thaiv qhov teeb meem no. Tsis tsuas yog txiv qaub efflorescence tiv thaiv. Nyob rau hauv sib piv rau cov cement, tras cement mixs txo qhov kev pheej hmoo ntawm discoloration nyob rau hauv lub ntuj pob zeb, uas yuav tshwm sim vim cov nram qab no proportions nyob rau hauv lub pob zeb:
- metallic
- organic
Note:
Qhov tsuas yog qhov tsis zoo ntawm cov khoom sib xyaw ntawm cov cement sib tov yog lub sijhawm kho kom ntev dua. Qhov no yuav tsum tau coj mus rau hauv tus account tom qab thov.
Application
Vim lawv cov khoom tshwj xeeb, cov cements nrog cov ntsiab lus tsis zoo yog tsim rau ntau yam kev siv. Lawv muaj txiaj ntsig tshwj xeeb rau kev sib xyaw mortars uas tsis muaj dej. Tshwj xeeb tshaj yog sab nraum zoov, mortar thiab pob zeb nrog cov thoob khib nyiab yog qhov zoo tagnrho rau ntau qhov chaw ntawm daim ntawv thov uas feem ntau los yog mus tas li los rau hauv dej:
- Terraces
- paving nto (bound)
- Groout
- dej hauv ob sab phlu (xws li lub pas dej hauv vaj)
- Monument restoration
Trass cement sib tov yog nrov rau kev ua cov pob zeb ntuj thiab pob zeb. Yog vim li cas rau qhov no yog qhov zoo khi ntawm txiv qaub. Nws tiv thaiv cov pob zeb los ntawm limescale efflorescence, uas feem ntau tuaj yeem tshwm sim vim ya raws sab nraum zoov. Ntxiv rau qhov chaw ntawm daim ntawv thov no, muaj lwm yam siv tau ntawm cov khib nyiab cement sib tov uas koj tuaj yeem ua kom zoo dua ntawm:
- Backfills
- Stone Stairs
- Screed
- Nkauj Masonry
Cov nqi
Yog tias koj txiav txim siab siv cov khib nyiab cement, koj yuav tsum xav txog cov nqi ua ntej yuav khoom. Hmoov zoo, cov no tuaj yeem txiav txim siab yooj yim heev vim tias cov cement tshwj xeeb twb muaj nyob rau hauv kev sib tov. Qhov no txhais tau tias koj tuaj yeem sib piv tus nqi khoom lag luam yooj yim ntawm lub khw muag khoom kho vajtse lossis cov khw muag khoom online. Cov khib nyiab khib nyiab feem ntau muaj nyob rau hauv tsib lossis 25 kg hnab, tshwj tsis yog tias koj xaj kom muaj ntau dua ncaj qha los ntawm lub tsev muag khoom. Yog tias koj txaus siab rau tus nqi nruab nrab, koj yuav tsum saib cov npe hauv qab no:
- 5 kg hnab: 5 rau 10 euros
- 25 kg hnab: 8 rau 30 euros
Note:
Yog tias koj nrhiav tsis tau lub hnab khib nyiab, nrhiav cov ntsiab lus sib xyaw cement, pozzolana cement lossis Portland composite cement. Cov npe no muaj ntau dua rau qhov sib xyaw tshwj xeeb.
