There has been a host of attempts in geo-polymer research to find a suitable alternative to the production of Portland Cement. Each of the prior research attempts at finding an alternative process to manufacture a cementitous alternative to the portland process has had its difficulties. Two part systems, expensive hardeners, and plasticizers and caustic chemicals all trying to use fly ash and other pozzolan materials, have been utilized in these research models worldwide with little success.
Blue Crete is a green alternative to portland cement. This high performance cement has its genesis in marine life, and has proven to be a "natural" alternative to the portland industry. It has twice the compression strength of portland and three times the tensile strength while having all of the desirable characteristics of geo-polymers without the price tag.
Researchers at Blue World Crete in Pompano Beach, Fla., announced their findings over a year ago, and now have had their product tested by some of the leaders in the worldwide cement industry.
According to Art Galietti, COO of Blue World Crete Inc., cement can be manufactured in portable plants simply by mixing a natural, "green" marine based, fully sustainable, catalytic material, (their "secret" powder) with natural aggregates and a little water, no heating or large kilns required. This new technology could be a boon to the cement industry in remote areas of the world.
Blue Crete looks like regular powdered portland cement and can be distributed in the same way. Its set time is uniquely adjustable without the use of any additives - from 15 minutes to 24 hours and anywhere in between. Blue Crete meets and exceeds ASTM standards.
Blue Crete Possible New Alternative to Portland Cement
