    abstract = {Solar energy is a-virtually unlimited source
whose power on the Earth’s surface is estimated at
20 kWh. This is >100 times higher than the predicted
values of electric power required for the planet as a
whole at the level of 2000; use of this huge energy source
is not associated with any environmental pollution.
Today, in the face of increasing limitations
onnot-reproducible energy resources, complexity
appreciation of their production attaches great importance
to the use of solar energy. Precast concrete industry is a
major consumer of thermal energy and the most
energy-intensive technological conversion which
consumes >70% of energy, heat treatment products.
Among the conditions used in the dry hot climate the heat
treatment method of the concrete, the most rational
method is solar thermal processing which in recent years
has been developed and put into production as
an-effective method of heat treatment of concrete
products using solar energy in open workshops and
polygons as solar thermal processing them using
translucent insulating coatings including helio-forma with
heat storage elements-helio warming using special
film-forming compositions. With the advent of combined
methods, solar thermal processing is possible year-round
use of solar energy for thermal processing of concrete and
reinforced concrete. Methods of heat treatment with the
use of solar energy are developed in the factories of
precast concrete which until recently was used only steam
heating. The variety of ways solar thermal processing
provides optimal and economical choice for heating this
type of design with minimal costs. Solar technology in
concrete production increases energy efficiency during
acceleration of concrete hardening including due to the
manifestation of the internal power exo-therm cement and
soft modes of heating and cooling products contribute to
obtaining high-quality finished products. Thus, our studies
have shown that the use of solar energy is a promising
method of heat treatment of concrete in a dry hot climate
the possibility of which has not yet been exhausted.
Today, broad investigations which would develop
methods solar thermal processing develop new and
facilitate their implementation in production. The
