Investigating and Comparing Ferrogeopolymer and Ferrocement Behavior

This report presents a comparative study of ferrogeopolymer concrete and ferrocement, focusing on their performance under flexural testing. The research investigates different wire mesh arrangements and their impact on the materials' behavior, including failure mechanisms. The experimental approach utilizes a four-point bending test with a Linear Differential Variable Transformer (LDVT) to assess the flexural behavior of the ferrogeopolymer and ferrocement elements. The study employs fine sand aggregate and Class F fly ash in the ferrogeopolymer mortar mix. The report also includes a discussion of the chemical reactions between sodium hydroxide and galvanized wire mesh. The results highlight the cracking patterns and failure modes of the specimens. The conclusion summarizes the comparative analysis of the two materials based on the experimental setups and literature review, providing insights into their respective strengths and limitations.

 Research deals with investigation of the performance of
concrete of a geopolymer material alongside the
ferrocement based reinforcement cement performance.
 After this, comparisons of the two brands are made in
relation to their behavioural failure.
OBJECTIVES
 Studying different arrangement of layers, their effects
alongside the wire mesh types.
 Investigating behavior and failure in relation to the
mechanisms of the ferrogeopolymer elements and
fibrocement flexures(Kumutha et al., 2016).
 Comparing load capacity in flexure and toughness
between ferrogeopolymer and ferrocement
PROBLEM DEFINITION

 The aim of this project is to give a comparison
between ferrogeopolymer concrete and
ferrocement with the use of flexural method of
testing (Hardjito, Djwantoro and Tsen 2013).
 Further, the literature review gave a
demonstration of how the approach to this
experiment should go (Banu,Saranya,Dharmar and
Nagan 2014).
Dimensions
 Basing our reference on the lack of information in
the section of the literature review, some
dimensions have been selected as samples.
Experimental Approach

Wire meshes
 Basing our information of the literature review, it was
founded that wire mesh of square weld nature was
preferred over other types of mesh (Qidwai et al.,
2016).
Four-point bending testing with Linear
Differential Variable Transformer (LDVT)
 From the literature review, flexure bending is
preferred for the elements of ferrocement. Therefore,
the testing here must show clear demonstrations of
the working procedures and practicality of
ferrocement reinforcement (Rashad,2018).

Materials
Aggregates
 Ferrocement is also referred as an element of a thin
cell. In this prospect, using course aggregate can
make the aggregate stick itself to the layer at the
top. This would create a void in the samples.
 Thus, the only filler used in this experimental setup
in this paper is fine sand aggregate (Amritphale et
al.,2018).
 the saturated Surface dry (SSD) preparation of sand
is in line with AS1012.2-1994 (AS/NZS 1994) but for
larger sand quantities, it proves to be difficult in
achieving the preferred condition(Ganeshan,
Mahima and Sreevidya Venkataraman,2018).

Ferrogeopolymer mortar mix
Fly ash Class F
 Scholars like Priya, Maheswari and Vaishnavi (2015)
suggests that a class F fly ash is greatly available
and is obtained from a power station with specific
reference to coal power (Bhatewara et al.,2018).
Mix Design
 To compare the two brands of ferrogeopolymer and
ferrocement, the mix design is selected to block the
diversion which produces results that are
incomparable (Shaaban et al., 2018).

4.1 Wire meshes
 4.1.1 Chemical reaction test
 From the previous section highlights, a
challenge was reported from the
experimental set up.
 To avert this, testing of chemicals are
necessary in order to assess the sever
nature of the reaction in the mixing process
between sodium hydroxide solution and
wire mesh which is galvanized.

 Characteristic compressive strength
RESULTS

 Examination of how the tested specimen in
reference to their cracking pattern and
shape failuris of great significance.
 Generally, most of the cracks appear at the
center of the specimen but not at the center
because of the manner of placing the chairs
of reinforcement (Abushawashi, Vimonsatit
and Shaikh 2018).

 In conclusion, this research paper has
highlighted three main tests of experimental
setups. T
 hese experiments illustrate a comparative study
between ferrogeopolymers and ferrocement
together with minor chemical reactions that
occur in the set up during the experiment.
 These are based on the works obtained from the
literature review which highlighted the previous
works of the scholars who attempted to give
explanations of the same set-up
