A method of making high performance concrete, the method may include adding ground glass powder (GP), nanosilica (nS) powder, cement, silica fume, fly ash, and sand to create a homogenized mixture. The method may also include homogenizing the mixture by mixing and adding water and superplasticizer to the homogenized mixture to obtain a slurry. The method may also include mixing the slurry until a high flowability mixture is obtained. The method may then include adding a first microsteel fiber (T1) to the high flowability mixture; adding a second microsteel fiber (T3) to the high flowability mixture; adding a third microsteel fiber (T4) to the high flowability mixture; and casting the high flowability mixture.

Concrete composition including nanosilica derived from glass waste

A method of making nanosilica from glass, the method comprising: gathering glass waste; grinding the glass waste to obtain a glass powder containing nanoparticles; adding the glass powder containing the nanoparticles to a water solution comprising a dispersing agent to obtain a colloidal system containing nanoparticles; separating the nanoparticles from the colloidal system to obtain separated nanoparticles; and drying the separated nanoparticles to obtain nanosilica.

Method for making nanosilica from glass waste

The present disclosure relates to a method of making nanoparticles from glass, the method including: gathering glass waste; hammering the glass waste into ready to grind pieces; adding an amount of the ready to grind pieces into a grinding bowl; adding steel balls to the grinding bowl; grinding the ready to grind pieces; and obtaining a powder containing the nanoparticles.

Effective method for producing glass waste powder as a precursor for the production of nanosilica

An ultra-high performance concrete (UHPC) including empty quarter desert sand (EQS) and micro-steel fibers (HyTUHPC). The ultra-high performance concrete (UHPC) can have a high viscosity due to the presence of EQS.
