Ultra Fine Rice Hull Ash (RHA) supplied by Tech Silica is a high-reactivity pozzolanic material manufactured using controlled combustion and precision grinding to achieve consistent ultra-fine particle size and high amorphous silica content. This ensures reliable performance in cementitious and industrial applications, where uniformity, reactivity, and material quality are critical. The refined structure promotes efficient pozzolanic reaction, resulting in denser microstructure and improved mechanical properties.

Tech Silica’s Ultra Fine RHA is engineered for use as a partial cement replacement in high-performance concrete, precast elements, and infrastructure projects requiring enhanced durability and reduced permeability. With strict quality control and consistent supply, Tech Silica delivers a dependable solution that supports lower cement consumption, improved long-term performance, and sustainable construction practices.
