Kev piav qhia
Tsawg-density silica fume, tseem hu ua microsilica, yog cov khoom lag luam los ntawm kev tsim cov silicon thiab ferrosilicon alloys. Nws yog cov khoom siv pozzolanic uas muaj zog heev uas tuaj yeem siv los ua ib feem hloov ntawm cov cement hauv cov pob zeb sib xyaw kom txhim kho lub zog, ua haujlwm ntev, thiab lwm yam khoom ntawm cov pob zeb uas tshwm sim.
Thaum siv hauv pob zeb, qhov tsawg-density silica fume tuaj yeem pab txo qhov ntom ntom ntawm cov pob zeb, ua rau nws yog qhov kev xaiv nrov rau kev siv pob zeb sib xyaw. Qhov no tuaj yeem tau txais txiaj ntsig tshwj xeeb hauv cov xwm txheej uas qhov hnyav yog qhov kev txhawj xeeb, xws li hauv kev tsim cov tsev siab siab lossis hauv kev thauj mus los ntawm cov khoom siv precast.

Qhov zoo:
Tsawg-density silica fume tuaj yeem pab txo qhov ntom ntom ntawm cov pob zeb, ua rau nws yog qhov kev xaiv nrov rau kev siv pob zeb sib sib zog nqus.
Nws tuaj yeem pab ua kom lub zog compressive thiab durability ntawm cov khoom tshwm sim.
Kev siv cov silica fume tsawg-density hauv pob zeb tuaj yeem pab txo qis permeability ntawm cov khoom, ua rau nws tiv taus dej thiab lwm yam kev puas tsuaj.
Nws tuaj yeem txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov pob zeb sib xyaw ua ke, ua rau lawv yooj yim los tuav thiab qhov chaw.
Kev siv cov silica fume tsawg-density hauv cov pob zeb tseem tuaj yeem pab txo qis cov cement xav tau hauv kev sib tov, uas tuaj yeem ua rau txo nqi.
Kev siv:
Tsawg-density silica fume feem ntau yog siv los tsim cov pob zeb sib sib zog nqus rau ntau yam kev siv, nrog rau cov tsev siab, cov khoom ua vaj tse precast, thiab kev thauj mus los.
Nws kuj tseem tuaj yeem siv los ua ib feem hloov rau cov cement hauv cov pa sib xyaw ua ke los txhim kho lawv lub zog, durability, thiab lwm yam khoom.
