Freeze-Thaw Resistance of Concrete Modified by Rice Hull Ash and Gangue

Abstract:

Currently, most rice hull is piled up or burned naturally, resulting in many environmental problems. It is a potentially good way to incinerate specially rice hull into the ash that is used as concrete admixture. The research work was done and results indicate that the compressive strength of the concrete with addition of 1%, 2% and 3% of rice hull ash increased by 6.8%16.7% and 15.1% respectively compared with control samples. And the compound addition of rice hull ash and gangue not only improved the mechanical and anti-freeze-thaw properties of concrete, but also decreased the cost of concrete production.
