ABSTRACT
The work presents the
results of tests on the shear parameters of walls made of AAC (autoclaved aerated
concrete, fb = 4.0 N/mm2) on the system mortar for thin M5 and M10 joints (fm = 6.1 N/mm2 and fm = 11.9 N/mm2)
and on polyurethane glue and also walls without mortar (dry masonry). The wall
compression strength (on mortar M5 class) (per EN 1052-1:2000) amounted to fc,mv = 2.97 N/mm2 (fk = 2.48 N/mm2),
elastic modulus was Ecm =
2,040 N/mm2.
Various structure of bed joints and head joints were applied and the following
were used as reinforcement: steel trusses of EFZ 140/Z 140 type (Z1 type) and
meshes made of plastics (Z2 type). Based on the tests carried out with regard
to unreinforced elements, it was shown that the filling in of head joints with
mortar had an advantageous effect on the values of cracking and destruction
stresses. While, with the use of reinforcement, advantageous increase of stress was obtained only
when the mortar was laid twice on both bed surfaces of masonry units. The
application of reinforcement in the bed joints when the mortar was laid only on
one bed joints surface of the masonry units reduced the values of cracking and
destruction stresses in relation to the values obtained in the unreinforced
walls.
