Scuba diving in Bali Eco Adventures in Asia
Off to go diving in Bali at the Tulamben wreck with a advanced open water diver from the UK Ema we were talking about engineering and she brought up a very amazing fact that 10% of CO2 emissions is generated from the manufacture of cement. The process basically involves cooking calcium carbonate at very high temperatures for very long times, and the byproduct is massive quantities of carbon dioxide.
To reduce it, we’re looking at replacing some of the cement in concrete with other products, such as fly ash (industrial byproduct) or alternatives to cement completely, such as magnesium oxide, although his is still being researched.. Increased proportion of aggregate can also reduce the amount of cement needed, and again recycled waste products such as sawdust or paper can be used. Bubbles of air can also reduce the amount of concrete used in a single block
The Bali diving in Tulemban is awsome Ema being a advanced open water diver was able to go deeper so we went down below the wreck and saw some excellent reef that even though we were deeper the colors were still quite vivid. We saw a Whip coral Gobbie while looking for the ghoost pipe fish.

I have done some research and put together some info on magnesium oxide. I am using wall boards made of magnesium oxide for my ceilings, walls, and floor tile underlayment in a coastal show house. You can access my page about it here;
