Sand for civil construction is running out in many parts of the world

Sand consumption today

In more and more parts of the world, the availability of sand is becoming increasingly difficult or even impossible for the construction industry.
Gigantic sales are now being made with sand.
Millions of tons of sand are transported to the oceans each year, and demand will continue to rise.

Example

• Over 47 billion tons of sand are mined annually
• For a standard house you need approx. 200 to of sand
• For 1 kilometre highway you need approx. 30000 to of sand
• For the project "The Palm Jumeriah" approx. 185 million to of sand was used
• For the project "The Palm Jebel Ali" approx. 450 million to of sand was used
• Global sand business is 70 billion US Dollar/year

A special UHPC Desertsand binder is for this purpose the solution of the problem. We were already executed first concrete constructions.
In my next post I will explain you the solution.
