Abstract
Sugarcane bagasse easily found in sugar factories of Bangladesh. Some of them are used as fuel in sugar mills and rest of
them are dumped into environment without any commercial return. The disposal of this material is causing environmental
problems around the sugar factories. On the other hand, urbanization and industrialization is rapidly increasing in Bangladesh.
So, the construction industry is rapidly expanding. Currently large amount of cement is needed for this construction industry. It
will be increasing day by day. The study examined the potentiality of using classified Sugarcane bagasse ash (SCBA) to replace
some part of OPC cement in concrete. In this study, bagasse sample was collected from Natore sugar mill. After collecting the
sugarcane bagasse, it was dried in sun for a week and then it burned in aggregate burning oven at 800°C to 1000°C temperature
for 20 minutes. Ordinary Portland cement (OPC) was replaced by SCBA at different percentage ratios at 0%, 5%, 7.5%, 10 and
12.5%. Normal consistency and setting time were investigated for these ratios. The compressive strengths of different concrete
with SCBA addition were also investigated. Strength was tested for 7, 28 and 56 days. The test results indicated that up to 5%
replacement of cement by bagasse ash results in better or similar concrete properties. It also showed the economic advantages by
using SCBA as a partial cement replacement material.

to its pozzolanic reactivity (Cordeiro et al., 2004). In this
country sugarcane bagasse as natural agro-waste materials
and it also obtained with requiring low cost, energy and
time. As per study by Mahamud et.al, 2012, in Bangladesh
around 425,000 acres of land are under sugarcane and the
annual production is about 7.5 million tons, of which only
Nowadays sustainable development and Environmental
pollution are the major issues in the whole world. Over 5%
of global CO emissions can be attributed to Portland
cement production (Worrell et. al, 2001). Production of 1
ton of cement contributes to about 1.25 ton of CO into

atmosphere (Griffin, 1987). Demand for cement is
increasing day by day in Bangladesh. Being a developing
country urbanization and industrialization is rapidly
increasing. The construction industry is rapidly expanding
because of infrastructure development of the country. A lot
of mega-structures such as tall buildings, bridges, offshore
structures, dams, monuments, fly way over, metro rail,
elevated express way etc. As most of structures are made
by concrete so, it needs a large amount of cement
production.
2.28 million tons are used in sugar mills and the rest goes to
molasses making. Bangladesh now produces about 150,000
tons of sugar, 100,000 tons of molasses and 800,000 tons of
bagasse per year. Bagasses are use as fuel in sugar mills
(
Habibullah et.al, 2014). According to Cordeiro et al.,

004, the resulting bagasse ash represents approximately
.62% of the sugarcane weight. Unfortunately, having
technical benefits, most of sugarcane bagasse are dumped
into environment without any commercial return. In
consequence, environmental pollutions are increased day
by day.
In Bangladesh, sugarcane bagasse ash (SCBA) can be
Proper consumption of these sugarcane bagasse
contributes in solving environmental pollution and
production of cost-effective concrete; it can also play a vital
role for the production of sustainable concrete.
