Study the Effect of Nano SiO2 Prepared from Rice Husk Ash on Compressive Strength of Reactive Powder Concrete
Nano-SiO2 was extracted successfully from rice husk ash. The obtained SiO2 powders exhibited a monoclinic crystal system, mesoporous structure, and a large specific surface area of 258.3 m2/g, with particle sizes ranging from 10 to 15 nm. Incorporati...
