Nowadays, Paper production industries are producing large amount of solid waste. Many companies burn their sludge in
incinerators which leads towards air pollution. This research is aim to evaluate the addition of waste paper to cement mortar
blocks, to study the effect of waste paper on the strength of cement mortar blocks, and also worked on testing of waste paper
sludge to find out the amount of chemical compounds are present which is co-related to cement.
The work shows the comparison of compressive strength of blocks made by waste paper sludge (WPS) as partial replacement
with cement, normal cement mortar blocks and conventional clay bricks by taking a mould size as a standard size of
conventional brick 19cm x 9cm x 9cm. We have used waste paper sludge as partial replacement with ordinary portland
cement by 5%, 10%, 20% and 30% respectively and cure the blocks for 7days, 14 days and 21 days to compare the
compressive strength by graph.
