Effect of pretreatment soaking duration to characteristic of ultrafine treated rice husk ash (UFTRHA) as supplementary cementing material (SCM)

Rice husk ash (RHA) possesses high content of amorphous silica that is essential in pozzolanic reaction of supplementary cementing material (SCM) in concrete strength enhancement. However, usage of conventional RHA is unfavourable in current concrete industry. One of the reason that hindered the ut...
