Specification of Micro Silica Concrete Admixture for High Performance Concrete in Marine Structures

Micro Silica Concrete Admixture for High Performance Marine Structures

Nws yog dab tsi

This admixture is a very great powder made mostly of silicon dioxide. It comes from generating silicon or ferrosilicon alloys. The bits are a lot smaller sized than concrete grains– feem ntau 50 rau 100 times smaller. Vim li no, it fills tiny voids in concrete and makes the mix denser.

Vim li cas Siv Nws hauv Marine Ib puag ncig

Marine moj khaum ntsib kev sib cuag nrog dej ntsev, nthwv dej, thiab huab cua phem heev. Cov pob zeb niaj hnub tuaj yeem tawg lossis siv maj mam. Xws li mini silica zoo heev txhim kho lub zog thiab ua kom muaj zog. Nws txo qis npaum li cas dej nkag mus rau hauv pob zeb. Qhov no slows down deterioration ntawm steel txhawb nyob rau hauv. Nws kuj tseem pab cov pob zeb sawv ntsug rau kev tawm tsam tshuaj lom neeg los ntawm dej hiav txwv.

Trick Benefits

Siab compressive thiab flexural toughness: Pob zeb los ua kom muaj zog sai dua thiab tseem muaj zog ntev dua.
Kev tiv thaiv zoo dua rau chloride nkag mus: Cov ntsev ions tsis tuaj yeem txav nrog cov pob zeb yooj yim. Qhov no tiv thaiv ingrained steel.
Tsawg permeability: Tsawg pores qhia tias dej tsawg dua, huab cua, thiab cov khoom tsis zoo tau txais hauv qhov sib tov.
Boosted workability nrog kev thov kom raug: Thaum siv kom tsim nyog nrog superplasticizers, qhov sib tov txuas ntxiv ua kom yooj yim rau qhov chaw thiab nto.

Yuav Siv Li Cas

Hom koob tshuaj ntau los ntawm 5% rau 10% los ntawm qhov hnyav ntawm pob zeb. Tsis tu ncua siv nws nrog lub siab-ntau dej reducer kom cov dej-cement feem txo qis. Sib tov kom huv si kom paub meej kuj faib. Kho cov pob zeb kom tsim nyog– tswj nws moist rau yam tsawg kawg nkaus 7 hnub. Qhov no pab cov micro silica hnov ​​​​mob nrog calcium hydroxide thiab txhim kho cov khoom sib txuas ntxiv.

Cia thiab tuav

Kav hauv ib qho qhuav qhuav, npog qhov chaw. Khaws cov hnab ntim ntim kom huv si kom tsis txhob dampness. Siv cov cuab yeej siv kev nyab xeeb thaum tuav– av npog qhov ncauj, tes npog, thiab shatterproof iav. Tiv thaiv kom tsis txhob ua pa ntawm cov hmoov zoo.

Vim li cas Micro Silica Teeb Meem Hauv Ib puag ncig hnyav

Cov txheej txheem Marine ntsib tas li raug rau hauv hiav txwv tob, nthwv dej, thiab hloov kev nyab xeeb. Cov xwm txheej no muab tso rau hauv cov pob zeb tsis tu ncua hauv lub sijhawm. Txhawm rau txhim kho kom muaj zog, cov chaw dej nyob ntev dua, Cov neeg tsim qauv siv cov micro silica ua ib qho tseem ceeb admixture hauv kev ua haujlwm siab.

Micro silica sau me ntsis qhov khoob ntawm cov cement hais. Qhov no ua rau lub pob zeb ntau denser. Ib qho sib xyaw denser thaiv cov dej thiab chloride ions los ntawm kev nkag mus. Qhov kev tiv thaiv ntawd txo cov hlau corrosion hauv cov pob zeb. Nws kuj txo qhov tawg thiab qhov chaw puas tsuaj los ntawm kev khov-thaw cycles lossis ntsev tsub zuj zuj..

Tiag tiag-lub ntiaj teb siv raws ntug dej hiav txwv

You’ll discover micro silica-enhanced concrete in several coastal jobs. Strong examples include piers, jetties, seawalls, offshore platforms, and bridge structures near the ocean. These frameworks need to resist consistent salt spray and tidal pressures. Including micro silica provides the sturdiness they need.

In port facilities, heavy lots and rough products add additional stress and anxiety. Concrete with micro silica manages this much better since it has higher compressive and flexural strength. It also shows much less permeability, which suggests less upkeep issues over years of service.

Kev ua tau zoo Koj tuaj yeem ntseeg Cov Nyiaj Txiag

Solid examination results back up its use. Concrete with 5– 10% mini silica substitute shows up to 30% higher toughness than conventional mixes. Nws tsis kam mus rau sulfate nres thiab alkali-silica cov tshuaj tiv thaiv ib yam nkaus li txhim khu kev qha. Cov yam ntxwv no yog qhov tseem ceeb uas cov dej ntsev chemistry tuaj yeem ua rau cov pob zeb zoo tib yam tsis muaj zog.

Cov neeg muab kev pabcuam txaus siab tias cov silica mini ua haujlwm zoo nrog ntau lwm cov khoom siv xws li superplasticizers. Qhov no ua rau lawv muaj peev xwm ua haujlwm siab thaum tseem ua tiav qhov ntom ntom, cov khoom ruaj khov kawg. Qhov tshwm sim yog kev ntseeg siab tau zoo yam tsis muaj kev hloov pauv loj rau kev tso lossis kho cov txheej txheem.
