Abstract
Recent developments in building energy
saving managements have led to considerable
improvements in energy savings of building sector.
Therefore looking at various optimization strategies
to reduce the building energy consumptions. These
measures include improving the building materials,
energy conversion technologies, control strategies
etc. But there is still a strong interest to reduce the
energy use of buildings through reduction of heat
losses. The largest source of energy Mineral wool
(or rock wool) is a non-metallic, inorganic product
manufactured using stone/rock. The Rockwool can
be placed inside hollow concrete blocks and the
insulation assessment of these materials can be
examined based on the heat transfer rate. This study
aims at the comparative study of Rockwool and
Thermocol (Polystyrene) insulation used in concrete
blocks. Cement-based composites are among the
most widely-used construction materials due to their
low cost, high compressive strength, high durability,
versatility, and easy-handling. Unfortunately,
cement-based composites are intrinsically porous
and may deteriorate and be liable to rebar corrosion
as a result of exposure to harsh environments or
poor construction quality. In general, proper design
procedures, adequate concrete cover depth,
corrosion-inhibiting admixture, and lowpermeability
cement-based composites can be
selected for corrosion prevention and control. There
are three type of concrete blocks used for this
analysis. The thermal properties of Rockwoolconcrete
composite and Thermocol-concrete
composite will be analyzed and will be simulated in
ANSYS. Thus we determine the effectiveness of
insulation provided by the Rockwool material with
the hollow concrete block. In hardware part rock
wool inserted building block’s thermal conductivity
is tested by ASTM C518 test method (British
standard).This analysis will help us to determine the
efficient insulator and will help us reuse the
Rockwool and Thermocol wastes generated in
industries and commercial sites.
