The along with its role in project success

research can be achieved either in a qualitative model or in a quantitative
model. Qualitative methods include inspecting words and quantitative method
involves inspecting of numbers. Thus, the qualitative model is more appropriate
for the research objective. A pragmatic study for feasibility of AAC block
manufacturing and to identify the acceptance of AAC over other blocks along with
its role in project success will provide with preliminary data for analysis.
The part of the research can be analysed with quantitative approach which make
this research analysis as mixed method approach where both the approaches can
be used.


Research Design
& Method


The research can be directed using a
cross sectional design or a survey method as it appears to be more apt to the
research objective as compared to other methods.

The primary data collection
techniques suggested in the literature for the cross-sectional approach are
questionnaires and semi-structured interviews. The questionnaires might contain
mainly closed ended question with few open ended question to gain insight from
user regarding the AAC.  However, Kothari (1990) claimed that interviews is more suitable for a qualitative
approach rather than quantitative approach as it results in formation of cause
and effect. Therefore, questionnaire with semi-structured interview is preferred
as a research method in order to collect data. The data gathered over initial
investigation could assist in forming a questionnaire. The questionnaire and
interview will target the specific focus group related to AAC along with
developers and manufacturers of AAC blocks to find the reason behind the
acceptance and feasibility of AAC compared to other bricks and blocks. The response
obtained through questionnaire can be further converted into statistical data
based on their significance. Whereas the data collected from semi-structured interview
will require empirical support to pursue for research hypotheses.

Thus, the respondents to this
research would be from the people consisting of a blend of small, medium and
large organisation of AEC industry such as architects, designer, contractor.
Also, the respondents would be selected such that they signify the AAC knowledge
adjacent to the industry which could lead to determination of reliable factors
by the experts in the industry. The aim for a mix set of samples is that this
could eradicate any biasness linked with a specific sector.

data may be categorized and sorted into patterns/themes as the primary basis
for organizing and reporting the study findings with further assistance of
tools which provide extensive coverage of formulas.


Chapter 4: Summary

All the major
industry round the globe are moving toward the carbon free world to have a
better future, where the construction industry should be the pioneer in this
category as they are the one responsible for constructing the globe for better
living for human being. Ironically the case is other way round and construction
industry is the 2nd most carbon emitting industry in the world. There is a robust body of authors writing explicitly
within the construction field who call for a change in construction material
which catalyst the building process. This led to replacement of building
materials with sustainable carbon free materials and replacing the red clay
brick and cement is one of the steps followed by the construction industry. The
autoclaved aerated concrete which is made from waste material from thermal
power plant i.e. fly ash which is the major part of AAC along with cement,
various fibres, silica and water is being heated at high temperature to
generate a chemical reaction which generates hydrogen gas which makes the AAC
block porous in nature. The porosity makes it a light weight concrete and these
blocks can be used in the constructing residential and commercial buildings as
they can sustain the impact of seismic vibration from the earthquake. Likewise,
porosity led AAC block to have high thermal insulation and water permeability
which suites the construction of building as maintaining the temperature got
easier and energy demand can be brought down substantially. As a matter of
fact, the AAC blocks being larger in size and have are less dense compared to
clay bricks even though the compressive strength remains the same, makes it an
ideal choice for replacement for clay brick. Apart from which AAC blocks
perform exceeding well in varied field of water absorption, moisture content,
curing behaviours, mortar requirement, quantity requirement, plaster
requirement, time require for construction, finishing alternatives, structural
behaviour, strength and stability when compared to clay brick and RC blocks.

a quantitative research is recommended for the project because of the nature of
the objective. The knowledge spawned from the empirical studies can support in
formulating a questionnaire and the data gathered by means of this survey and
interview could be studied using tools and pattern/theme interpretation.
