dont think cement is imported in west malaysia. not sure about east tho.
i heard CMS business is so good that during long maintenance they buy from west malaysia as well to sustain the consumption.
producing will be cheaper unless in countries like myanmar.
even if import/export they usually do clinker .
they will still need to grind at the respective places to produce cement.

Edit: if im not mistaken , clinker from japan abit cheaper as in japan cement is usually the byproduct.
they actually use the cement kiln to burn of waste( something like alam flora).
they earn money from the waste disposal.
clinker they jsut sell off as a byproduct to earn more money.
not sure about the quality tho.

there is special cement called fly ash cement. some grinding plant use it. meaning they buy those fly ash from power plant then mix with with clinker at a certain ratio to produce fly ash cement.

i remember it has a longer curing time but less heat during curing so we can cast at bigger block size without cracking (i hear before as one of building uses it) im not involved in construction.

Whoa. I didnt know different sand will cause these problems in concrete. lol. So for plastering new wall, sand also plays a factor in it? Because I have seen new wall plastered and within months crack again.. :\

Are you in construction line????

Total 6 companies/group in malaysia cement industry,which one is the best quality???

Oh, but how do i know that the sand I ordered is salt water sand and not river sand?
