ABSTRACT: A powerful non-destructive testing (NDT) technique is adopted to study the quality of RHA brick-1
and RHA brick-2. In that case, rice husk ash has been utilized for the preparation of bricks in full
replacement of clay. In these studies, homogeneity of elemental distribution, water absorption
and size and shape of the pores have been observed. From the studies, it was observed that elemental
distribution is very good at various level, large number of porosity is presented with little
bit size, initial rate of absorption (IRA) due to first five minutes immersion of water is higher
compared to other immersion time (>5 minute), incremental water intrusion area increases very
slowly with the increasing immersion time and the water absorption for RHA brick-2 becomes saturated
very early than that of the RHA brick-1.
