Mexico:Cinestav creates organic cement

Mexico's Cinestav researchers have developed an organic cement cullet, aorganic  variety cement i.e. resistant to moisture based on glass recycling urban waste hydraulic cement, reports El Sol de Mexico.

The group of experts led by Jose Ivan Escalante Garcia uses all kinds glass is washed, dried, crushed and ground before being combined with limestone, an abundant mineral and very low cost. Next, activate the obtained mixture with a solution of alkali compounds.

"By subjecting cullet to a chemical activation with alkaline compounds we induced a series of reactions leading to the solidification of what was initially a similar paste which form Portland cement mixture with water. This paste hardens and finally develops excellent mechanical properties that make the proper cement to produce concrete for various applications, "said researcher at Cinvestav.
