4. Conclusions
The following conclusions resulted from this research:
(1) Mortars containing PSA and EPS had lower thermal conduc-
tivity than control mortars. For example, thermal conductiv-
ities of mortars containing 30% PSA were reduced by 70% for
ground EPS and 68% for powdered EPS relative to the control
mortars which contained neither PSA or EPS.
(2) Bulk densities of mortars were also reduced by PSA and EPS.
In the case of mortars containing 30% PSA, densities were
reduced by 45% for ground EPS and 42% for powdered EPS
relative to the control mortar C.
(3) The reductions in compressive strength relative to control
mortars were lower for mortars containing powdered EPS
than with ground EPS. For mortars containing 30% PSA the
compressive strengths were reduced by 96% for ground
EPS and 88% for powdered EPS relative to the control mortar
C.
(4) Ground EPS reduced thermal conductivity, bulk density and
compressive strength more than an equivalent amount of
EPS powdered.
(5) Mortars containing up to 20% PSA, and either powder or
ground EPS are suitable for type CS III rendering and plaster-
ing applications in the EU. For type CS II applications, mor-
tars containing up to 30% PSA (with powdered EPS) and up
to 20% PSA (with EPS ground) are appropriate. For CS I appli-
cations, mortars containing between 30% and 60% PSA (for
ground EPS) and between 40% and 50% PSA (powdered
EPS) are suitable.
(6) It is possible to manufacture sustainable mortars containing
PSA and EPS that are in compliance with EU standards for
rendering, masonry and plastering mortars.
