A new cement that will absorb co2 from the atmosphere and a new product called cinder blox

Question

Why aren't governments forcing companies to use a certain percent of these materials? Or at least help these new products get known to consumers? Think how much cleaner our cities would be and also the trees that would be saved by using cinder blox around the world instead. So is there a government plan anywhere??

Answer 1

i've not heard of either.

did you want to post a link?

however, making cement is very energy intensive.

before you go expanding use of something that absorbs CO2, it would be good to consider how it's made, and how much CO2 is created in that process.

Answer 2

may b the gov doesnt know that this item even exsisted :/  

Answer 3

You're preobably referring to Eco-cement, which was developed in Tasmania. This requires magnesium compounds instead of the normal lime-stone derived calcium compounds. The mix seems to work well, and the curing concrete reabsorbs as much CO2 as is created to make it, if not to deliver and place it.

The problem is to switch the whole of the industry over to using the magnesium compounds. Since a lot of the magnesium is extracted from seawater, this may lead to unexpected problems if done on a large scale.

"Cinder blocks" is simply another name for ordinary concrete blocks. The 'cinder' part may come from the use of some flyash in the mix, flyash being the solid leftovers from burning coal or some other things ( like rice hulls.)

Personally, one could use  something ike Compressed Earth Blocks, aka CEBs, which is simply earth compressed into bricks and blocks under very high pressures.

CEBs Wiki:

http://en.wikipedia.org/wiki/Compressed_...

The earthen mixture ( earth, clay, and sand) may be stabilized by adding some Portland cement, or better yet, lime.

Lime is neat because as it cures, it re-absorbs all the CO2 made in it's production.

CEBs are basically an updated, standardized type of adobe building block. CEBs can be made with hand operated machines, or with motorized hydraulic machines of various sizes.

Building by hand is hard work, but the blocks will be nearly free if the soil on your property is suitable for it, or if the haul distance isn't very long.

Earth Building is an interesting subject, and I will tag on some links for your files.

Earthen building methods include adobe, CEBs, rammed earth, stabilized insulated rammed earth ("S.I.R.E.wall" ), cast earth, 'cob', 'wattle and daub',and "earthbags."

Google for them, and enjoy the journey.

About 1/3d of the people on earth live in houses made from earth. More if you bake the earth mix and call them "clay bricks"...

Hmans are so-called because they were created "ex-humus"-- from the soil. So why shouldn't their houses be from the soil?

Cheers.

Answer 4

Get smart and plant a tree to recycle Co2 into O2. Sequestering in any form removes breathable oxygen from the air.

Answer 5

Because the government shouldn't dip into peoples personal endeavors.

Answer 6

I'd like to know about the CO2 concrete too,  but the best solution is coming, hybrid and electric cars, non-carbon burning sources of energy, and planting trees, and green live roofs.  Plants.  My city's government is almost fanatical about trees, planting more and more, and made it illegal to cut down trees, and we already have millions of acres of parks full of trees.

Cinder blocks are concrete blocks, and ya, you don't need to cut forests down to make them, and I sell many thousands of them, and they're great protection from spreading any fires, and shield out noise, and protect people inside from things that might hit buildings.  Are your Cinder Blox something other than regular concrete blocks ?  I'd like to know, could spread the word too.

Answer 7

The government has to figure out a way to make sure this product is taxed properly before they release it. We all know "green" mean EXPENSIVE.

Why doesn't the government promote recycling more? Giving companies a tax credit for the amount they recycle legitimately. With a ceiling on the credit of course. Also a tax credit for reducing energy used.
