Korea is great, but here is another testament to the fact that the world's best architects certainly aren't from Korea. Why oh why do they make apartments and villas with concrete walls? My Mom told me my aunt and uncle used to live ina ouse made of concrete. The walls would sweat and they had to constantly wipe them down, and that's why they ended uo moving into another house. In Korea, I can't understand why they make apts. with concrete walls, and more importantly, why do they wallpaper them??? Shocked This is the reason so many places have mold coming in on the walls. The concrete produces moisture/sweat, and then it comes through the wallpaper, and voila, what do you have??? That's right...MOLD...that's M-O-L-D...MOLD!!! Not too architecturally bright, huh??? Confused

Compared to the hollow driwall in Japan, I prefer the solid acoustic barrier of concrete. The key is to move to new buildings before the sweat and mold show up.

Korea is the largest producer of concrete in the world.. they need to find as many places to put it as possible..

Sorry, my mistake. They are the largest per capita.

minerals.usgs.gov/minerals/pubs/commodity/cement/cemenmcs05.pdf

look at this file and scroll down, page 2. only countries like China, US, India, which dwarf in population produce more.

Are you talking about cement or concrete?

I got this whole thing confused. They are the largest per capital cement and concrete producer in the world.

They have many construction projects in the middle east and they used to produce all the cement/concrete in Korea and ship it by barge to the ME.

The three gourges dam took up 26.43 million cubic meters of concrete, which at 1700-2300kg/m3 of concrete is anywhere from 44,931,000,000
to 60,789,000,000 tons of concrete.

Which at China's production capacity of 850,000,000 tons/year would take them anywhere from 52.86 to 71.52 years to make. Even if the world's whole production at 2,000,000,000 tons, this project would take over 20 years minimum to generate the concrete needed.

Somewhere the numbers must be wrong, unless they were preparing the concrete years before the project began in 1993, or were producing more than 850,000,000 tons in the early stages.

Yes, you are confused. Let's deal with cement first. Here are the big Asia players:-

Cement Production 1989 (in 1000s of metric tons) 1000s Tons Rank
China 207,000 1
USA 78,559 2
Japan 77,556 3
South Korea 30,122 4
Taiwan 18,043 5
Indonesia 12,091 6
Thailand 11,514 7
North Korea 8,200 8
Philippines 4,092 9
Malaysia 3,775 10

One could imagine that in countries developing infrastructure demand for cement would run higher than in countries where that infrastructure is in place. That fact renders the USA comparison less relevant. Japan is a bit special as they operate "pig-trough" local politics and are still busy building bridges from next-door-to-nowhere to next-door-to-nowehere.

It is perhaps partly true that Korean cement production is increased by their ME projects, but most ME countries have their own cement production plants and contractors are obliged by contract to use local products where available.

The reality is, that for large bridges and elevated highways, Korea generally uses steel for spans restricting concrete (which demands cement) to the supporting piers. In office construction, the structural material of choice is also steel. Building construction in concrete is more limited to smaller buildings and high-rise residential complexes.

This is one of those complaints that confuses me. Back in Canada I lived in a concrete apartment building. It was strong, well built, and I couldn't hear my neighbours unless they were having really loud sex.

Ok, you're using statistics from 1989, while i am using stats from 2003 and 2004. Why are you using information that is nearly 18 years old?

Who is more confused?

and per capita means divide by the population. Korea is #1 then. Cement or concrete.

Obviously you didn't understand anything about the Three Gourges Dam example.

ME people hardly work, they import their labor, and most of them are on a one year visa and must go back and cannot live together with the citizens.

Please provide proof that subcontractors must make all the concrete/cement locally in the ME.

You also left out other uses of concrete, which are dry docks for shipyards. You can do the math, find out the square meterage of area for the shipyard, as well as the drydock space, it all must be covered in concrete.

Also, anytime you build a factory, you must lay down concrete. Korea is still a major manufacturing nation.

Who the hell cares which country produces more concrete or cement? What a pointless argument.


Likewise, who the hell cares whether Korean construction firms use steel or concrete? Each material has its own advantages and disadvantages. I'm guessing Mr. Kim at Samsung Construction knows more about engineering than Princess.
