| Summary: | In relation to the conventional concrete then foamed concrete (FC) is weaker. Therefore FC
was added by Rice Husk Ash (RHA) to alter the strength without eliminating its characteristic as
aerated concrete. Actually function of RHA is substitute the sand partly. The strength of concrete
affects to prevent the dynamic impact loading. However FC as aerated concrete can absorb energy
impact by its porosity. Both of characteristics were presented in this investigation. SEM and EDS
detected that pozzolanic reaction was done when FC was processing hydration of cement in
admixture. The presence of RHA increased the strength of concrete owing to cement hydration
process and pozzolanic reactivity of RHA. The result of impact loading on slab FC target displayed
that FC with RHA was more shallow than without RHA. Beside of that local damage showed that FC
with RHA denser and is not impression of fragments than FC without RHA. |
