Nanospheres Lead to Stronger Concrete

Nanospheres Lead to Stronger Concrete
Sep-27-18
Tiny spheres made of calcium silicate could lead to a greener and more stronger concrete.

Concrete is an extremely popular building material, but its production is resource-intensive. To offer a greener alternative, the team from Rice University replaced the cement commonly used as a binder in concrete with micron-sized calcium silicate spheres that will self-assemble into a solid material that is stronger and more robust than Portland cement. According to the team, the nanosphere-based material is more controllable to manufacture, and could even have applications in bone engineering, insulation and ceramics.

This is a very interesting invention if it is environmentally friendly and more cost-effective than portman cement. I would be interested to have more information with regards to its cost for production and whether it is possible for a collaboration to have it manufacture in China if it is more cost effective and environmentally friendly than portman cement.
Appreciate you could send me more detail information to aqualifehk@yahoo.com for consideration. I could be contacted at +86 139 2429 2080, My skype id: witallyltd
Looking forward to hearing from you at your earliest.
Best regards
