Silica fume will protect concrete against deicing salts, seawater, traffic and heavy impact. Rebar corrosion activity and concrete deterioration are virtually eliminated, which minimizes maintenance expense.
High-strength concrete enhanced with silica fume provides architects and engineers with greater design flexibility.Traditionally used in high-rise buildings for the benefit of smaller columns (increasing usable space) high-strength concrete containing silica fume is often used in precast and prestressed girders allowing longer spans in structural bridge designs.

SY (SanYuan ) company started to research and promote microsilca since 2001,then we built the production plant. except the original Yinchuan factory, Gansu Sanyuan has established a new"Lanzhou factory". It has also
upgraded the Yinchuan factory, result in made the Yinchuan factory safer, more technological, more efficient, and more environment-friendly (add a full set of environmental protection equipment and add the screening and classification functions of the original equipment). Our company has added the Tianjin Distribution Center on the basis of the original three storages of "Gansu, Ningxia and Inner Mongolia", achieving secondary quality inspection and fast transportation.
We have been producing and selling microsilica nearly 20 years. So we are very professional and experienced in this filed. Our annual production capacity is over 100,000 tons. Sanyuan is one of the industry leaders of microsilica
products in China for decades, mean while we participated in the drawing of Chinese national standard for microsilica.
