Abstract

Catalyst is being used by various kinds of industries and most of it are in process plant as
booster for reaction.. After some time, the catalyst can no longer be used and then
reprocessed is needed to make it become useful. Results of the process, another undesired
product or catalyst wastes are being produced. These wastes are normally dumps into
landfill but the increasing quantities and occupy big areas and poses into danger of nature
pollution.
Concrete technology currently focuses on the cement replacement material (CRM) in order to
find alternatives for cement usage. Pulverized fly ash (PFA) and silica fume are the most
common cement replacement material which being utilized from waste material. The
contribution in term of strength, durability and permeability are the ultimate goal of
collaborating with CRM besides the economical point of view.
The main objective of this project is to observe the possibility of recycling the catalyst waste
which is called `molinex' into concrete and cement mortar. The research is based on the
contribution of waste molinex in mortar in term of compressive strength.T he approach used
is to determine the oxide content of molinex and cementitious material (silica oxide) are
expected from molinex. Scanning electronic microscope is employed to examine this waste.
Study on molinex as sand and cement replacement is also conducted. Effects of both
replacements on compressive strength are carried out at 3,7,28 days.
In conclusion, it has found that molinex do contribute to the strength development of mortar
according to experimental casting of molinex as sand replacement and cement replacement.
