A question for the wall materials???

[ella_yan]

:) Hi, guys

I have a question for a type of wall materials called FGC wall board, it should be a type of wall materials. Anyone konws that? Who can tell me?

:confused:

A quick google makes it look like this might be one of the chinese contaminated drywall products that have been making the news. One type called FGC is using byproducts of powerplant flue gas scrubbers as a component of the gypsum.

It also looks like sections of China are banning the production of red brick due to environmental concerns and they are experimenting with a fire resistant wallboard made of crop stalk residue. In the US we look for a code approval report before using any new or unknown products.

Not sure if any of this applies to what you're asking, it was a new acronym to me so I simply did a quick search of the term.

The production of red brick is not being banned. They have been working on it for 10 years and have made a dent in a conversion. The have selected concrete and concrete block as the "official" wall material because of energy, ecology and fact the lightweight construction is considered cheap, temporary and inferior. This applies to housing which is the biggest part of construction. There is lightweight wall systems used on the 20+ story commercial buildings.

The scope of phasing out the old brick plants is mild-boggling even to the Chinese. Some cities my have 1000 clay brick plants and the cities over 5,00,000 (about 20 of them) cities each use more each in a year than the entire U.S. The Chinese use an average of about 600 brick per year for each man. woman and child year in and year out. (all 1,200,000,000 of them)

The reasons are not just just environmental, but ecological, energy and financial. Most of the people in China live in a cities that are on rivers that have good topsoil but a solid base underneath. The clay deposits are horizontal and require large area where the top soil is removed and then the good clay is mined as deep as it is good (usually 15 to 20 feet). Most of the pits are not filed because there is no good soil around and the top soil has be taken elsewhere because China has limited agriculture - the vast majority of the country is mountainous, rocky or a desert. Most of the pits cannot be drained, so they just fill with water that becomes undesirable.

The old brick plants use the cheap soft coal that is common and the energy costs are high and the pollution caused is bad when it is added to the increasing number of new imported cars from Germany and the U.S.

The loss of the valuable land impedes development. Concrete and concrete block use rock and sand from the river beds and from quarries, which are vertical and can easily be located a short distance away from the cities, so not valuable land is lost. From a energy production standpoint, these products use much less energy and and they can easily be fitted with pollution controls. The thermal properties of block and concrete are very adequate for the climates and the Chinese go not go for the R-value but go far beyond the fictitious, short term, lab results that are touted in advertising by the pink panther and others. Fire ratings of these materials are superior to lightweight walls. Is is especially true when you build housing in groups of 10 or 20 - 5 to 7 story buildings with a thousand units in each building, it is necessary to have hard walls and fireproofing for all interior walls. Compounding this is the fact there is usually several other similar complexes a block or two away.

There may be enough waste scraps to take care of a portion of the current drywall production current market for the few projects using lightweight walls. There is really not a lot of agriculture that produces a great deal of waste. The easiest place to grow anything is the extreem south and east part of the country. China has little wood resources and actually is a importer of wood from Russia,SE Asia. and some from the U.S.

Seeing China is a shock. Flying over most it, you rarely see a town or city because of the rugged terrain (rocky hills or mountains) or it may be a desert. In and around Beijing and Shanghai the rickshaws usually see are outnumbers by the Mercedes, BMWs and Buicks. The exceptions are the old area with narrow streets where a tourist can get a ride on one. I have been there about 5 times and every time I see changes and new things that really surprise me.

Wooow~~ so expert!!!

Regarding to the kind of product, if other countries are working on it ? Or other similar products?

Maybe the kind of product only is applied to drywall system in China.:mrgreen:
