Investigation on Basic Properties of Rice Husk Ash – Blast Furnace Slag Composite Binder

This paper studies the changes of composite binder basic properties caused by the addition of processed rice husk ash and blast furnace slag. Experimental results show that the fineness and pozzolanic activity of rice husk ash, slag in appropriate treatment are according to using standard. This novel composite binder becomes a little worse in availability performance, while its long-term strength is equivalent with normal cement.
