3. ABSTRACT
• The most important and widely used material in construction is concrete and its major component is cement, basically known as Ordinary
Portland cement (OPC). Since, OPC is well known for its high emission of CO2 gas.
• When looking for alternatives that need less energy or raw materials other than limestone will help minimize CO2 emissions from an
environmental standpoint. Geopolymers are promising alternative materials for Portland cement.
• Geopolymer are amorphous three-dimensional Alumina-Silicate binder material, which is produced by copolymerization of aluminosilicate
materials with alkaline solutions, exhibits higher mechanical strength and excellent durability properties.
• Several aluminosilicate industrial wastes such as fly ash, Metakaolin, red mud etc. can be used as source materials for geopolymer concrete
production. These wastes are used as source materials to produce geopolymer as it contains high silica and alumina content.
• In the present experimental study, Red Mud, incinerator waste and Micro silica as binder need to be added alkaline activator in the form of
sodium silicate (Na2SiO3) and sodium hydroxide (NaOH). Molarity variation of NaOH is taken as 6, 8, 10 M.
• Mortar proportion with 30% red mud and 60% incinerator waste exhibited maximum strength. Highest strength obtained for geopolymer
mortar was 2.36 MPa with 30% red mud and 60% incinerator waste and 10M molarity.

4. INTRODUCTION
• Concrete is the most predominantly used construction material. The basic ingredient of concrete is
cement, the mass production of cement increases carbon footprints and thus becomes a major
contributor for global warming.
• One promising option to lessen the environmental impact of conventional cement-based materials
is Geopolymers.
• Geopolymers are alumina-silicate bonds which are sustainable, inorganic materials used in
construction that can replace traditional cement and concrete, offering environmental friendly
alternatives with strong, durable properties.
• Since, cement contains alumina, silica and other elements. Here in this study, Incinerator waste
and Red mud that is produced by industries containing alumina and silica which goes as landfill is
used as an replacement for cement.
• Physical and chemical properties of red mud and incinerator waste are investigated.
Microstructural analysis are studied and a comparative explanation between strength parameters of
two the samples are presented.

Effect of Molarity on Compressive
Strength of
Geopolymer Mortar
2014 IJCER C.D. Budh
and N.R. Warhade
Tests was carried out on 70.6x70.6x70.6mm Geopolymer mortar specimen.
The ratio of alkaline liquid to fly ash is taken as 0.5. The obtained compressive
strength was validated by NDT results. Compressive strength increases with
increase in molarity. Also, velocity increases with increase in molarity.
Characterization of Red Mud as a
Subgrade Construction Material
2015 - Sarat Kumar Dasa ,
Subrat Kumar Routb ,
Shamshad Alam
Basic properties like specific gravity, particle size distribution, Atterberg’s
limits, OMC and MDD are determined. Engineering property like shear
strength are determined. The model footing test was performed to check
sustainability of red mud as pavement subgrade material. FE analysis was
performed and results were compared with the laboratory results.
Effect of curing methods of red mud
based geopolymer mortar
2017 IAEME Smita Singh, Dr. M. U.
Aswath, Dr. R.V.
Ranganath
Compressive strength, tensile strength and modulus of elasticity thermally
cured and ambient cured specimens were discussed. Strength of thermally
cured mortar improved with molarity whereas ambient cured mortar possessed
better strength at lower molarity. Tensile strength followed similar pattern as
compressive strength. Ambient cured mortars were found to be stiffer than the
thermally cured ones.
Effect of Alkaline Solution with Varying
Mix Proportion on Geopolymer Mortar
2017 IOP Ananthkumar M,
Raghavapriya S
Specimens of different NaOH solution (10M, 12M and 15M) for different mix
proportion (1:1, 1:2 and 1:3) and 60°C-80° C curing temperature were cast.
The densities, compressive strength, alkalinity, co-efficient of absorption were
determined.High curing temperatures produces higher strength. Mixes with
12M showed higher compressive strength than the rest proportions.
Effect of Mix Parameters on Strength of
Geopolymer Mortars
Experimental Study
2018 - A. Naghizadeh and S.O.
Ekolu
1.0- 3.0 (SS to SH) alkaline activator ratios were used with SS modulus= 2.5
and NaOH as 10-14M. Mortars of 2.25 A/B ratio were used to prepare 50 mm
cubes with L/S ratio from 0.3-0.6. All specimens showed significant influence
on compressive strength development. But, the optimum strength was at
SS/SH= 2.0 , 12M and L/S=0.5.

Preparation of red mud-based
geopolymer materials from
MSWI fly ash and red mud by
mechanical activation
2018 Elsevier Yuancheng Li, Xiaobo
Min, Yong Ke, Degang
Liu, Chongjian Tang,
Municipal solid waste incineration fly ash (MSWIFA) and red mud were utilized to
prepare red mud-based geopolymer materials (RGM). The hydration characteristics
long-term stability and physical properties of RGM were tested. Results showed
that mechanical activation can not only effectively activate red mud, but also
effectively improve the reaction of MSWIFA and red mud. When 14% sodium
silicate was added to the binder, the UCS reached 12.75 MPa at 28 days.
Performance of geopolymer
mortar cured under ambient
temperature
2019 Elsevier Mohamed G. Khalil,
Fareed Elgabbas ,
Mohamed S. El-Feky ,
Hany El-Shafie
The base material (GGBS and MK), water/binder ratio (0.0, and 15.0%), and
modulus of silicate (1.1, 1.3, 1.5, and 1.7) were considered. Fresh and hardened
properties were examined. It was observed that by increasing the modulus of
silicate, the workability increased and the compressive strength decreased. 1.7
modulus of silicate is the optimum mixture and compressive strength of the
optimum mixture after 7, 28 and 90 days of water curing were 19.6, 33.4 and 35.6
Mpa and its flowability was about 150%.

2019 IJCSM Subhashree
Samantasinghr and
Suresh Prasad Singh
fresh and hardened properties of fly ash and slag blended mortar are investigated
and results are determined. Additionally, bonding and microstructural changes are
examined. The fresh properties of geopolymers were found within the prescribed
range of OPC. compressive strength of mortar specimens increases with an
increase of slag content in the mix
Compressive strength of mortar

GGBS
2020 IOP Sagarika panda,
Ramakantha panigrahi
Fly ash and GGBS as binder materials, specimens were prepared for compressive
strength check. Compressive strength achieved from temperature cured is higher
than ambient cured samples. GGBS content was directly proportional to the
compressive strength of mortar specimen.

2024 IOP Ali Abdulhasan Khalaf,
Katalin Kopecskó
Statistical analysis has been performed on the major oxides of red mud to
understand the relationship between chemical composition and properties (e.g.,
workability, setting time, compressive strength, etc.) of red mud-based geopolymer
composite. With the results, it is concluded that red mud can be a suitable binder
by blending with other geopolymer source materials to achieve the desired fresh
and mechanical properties.

The EDAX patterns of red mud consists of elements like Na2O(10.41%), MgO(1.66%), Al2O3(26.74%), SiO2(8.10%), K2O(0.29%),
CaO(1.32%), TiO2(4.42%) and Fe2O3(47.06%). On observation, Aluminum content was sufficient and less hazardous.
The EDAX patterns of incinerator waste consists Na2O (1.75%), MgO(2.90%), Al2O3(0.85%), SiO2(2.19%), K2O(3.19%), CaO(82.91%),
TiO2(1.56%), P2O5(1.86%), SO3(1.05%), Fe2O3(1.04%). On observation, Micro silica was added to improve silica content.
• On trying different molarities on different proportions, the optimum molarity is found to be 10M for all three percentages of red mud
variation of mortar composition 1:3 binder to fine aggregate ratio.
• Out of three Mortar proportions, Mortar proportion with 30:60:10 (Red mud: incinerator waste: micro silica) i.e., 30% Red mud and 60%
incinerator waste exhibited the maximum strength.
• Compressive strength of geopolymer mortar samples increases with increase in red mud percentages.
36
37. SCOPE FOR FUTURE WORK
• Red mud and silica based geopolymer blocks can be tested for durability.
• Other waste with presence of silica can be tried with red mud.
• Also, the incineration waste can be tried in combination with other waste containing alumina.
• Can be tried for 12 Molarity and above variations.
• Can be tried for concrete as well.
