Self-weight of building units, construction time and sound workmanship are key factors
affecting the quality and cost effectiveness of masonry construction. Amongst the loads a
structure should resist, self-weight is a major component thus the reduction of self-weight by
introducing lightweight material would effectively reduce the load as well as the cost of
construction. Furthermore, large individual units would help speedy construction and results
in cost reduction. Yet, it is difficult to achieve sound workmanship in construction of masonry …

This research was to study the mixture ratio of lightweight interlocking blocks from sludge
mixed with 3 types of pozzolanic materials such as bagasse ash, diatomite, and rice husk
ash by calculating the cement mixture ratio with sludge replacement percentages of 20 80
by weight of cement when obtaining the appropriate mixture ratio with respect to
compressive strength that passed the standard and lightweight before replacing the sample
with 3 types of pozzolanic materials at 10% sludge by weight for determines the mixture ratio …
