| Summary: | Recently, incorporation of cement replacement material (CRM) in concrete has gained
considerable attention throughout the world. It is known that the commonly used CRM in current
concrete industry is silica fume (SF), pulverized fuel ash (PFA) and rice husk ash (RHA). RHA is
an agricultural waste from rice milling process. Rice farming activities is one of the main crops
planted in Malaysia and therefore, the rice husk abundantly generated every year. RHA exhibits
positive pozzolanic reaction during concrete strength development. The material contains
amorphous silica and hence it contributed towards enhancement of various concrete properties. This
paper presents a short review of RHA properties as CRM and pozzolanic reaction determination
Keywords: Rice husk ash; concrete; properties of rice husk ash; pozzolanic reaction determination. |
