Actually in Mexico and internationally will be increasingly evident the need for
buildings to conserve environment conditions of thermal comfort and his
highest the energy cost that implies the use of conventional air conditioning
equipment demand. Contemporary residential or industrial buildings are using
new building materials and techniques and the interaction with thermal
energetics processes, the characterization of those materials is required. In this
work is presented an equipment for measuring the thermal conductivity
proposed here, bases its principle on the Fourier law through the insulated hot
plate technique for low temperature using the norm NMX-C-189-2010 and
ASTM, contemplating homogeneity and isotropy in the materials. Its operating
range limit when making measurements is for the range of 10 ° C on the cold
plate and 60 ° C on the hot plate. The transfer of energy in the form of heat
through the thermal conduction mechanism is a directly proportional function
of the thermo-physical property of the thermal conductivity. This is intrinsic to
the material and its conditions for good operating performance and its
efficiency. The material tested is a new material that intends as mixture of
mortar used in construction for the central region of our country. The results
show the transient profiles of the temperatures during the experiments until
their stationary and the measurement of the conductivity has good agreement
with those reported in the literature.
