Abstract


ABSTRACT
This research aims to know the capacity of split tensile strength of the mortar and
lightweight mortar composition effective for wall with using pumice breccia. Pumice breccia is an
aggregate that has a good thermal insulation and easy to obtain. In addition, pumice breccia is
lightweight aggregate that resistant to earthquakes. However, pumice stone has not been used
optimally for structural elements. This research was conducted with the experimental method. In
this study, there were 27 specimens that used for testing the split tensile strength of mortar.
Each type of mortar mixture comprised of 3 compositions used were normal mortar 1PC: 4PS,
1PC: 6PS, 1PC: 8PS ; normal mortar pumice 1PC: 2PS: 2PM, 1PC: 3PS: 3PM, 1PC: 4PS: 4PM
; pumice mortar 1PC: 4PM, 1PC: 6PM, 1PC: 8PM. The proportion of the mixture obtained from
the calculation of the volume of the test object is used. Each composition of the mixture was
made 3 specimens with cylinders 150 mm x 300 mm. The results showed that the split tensile
strength avarage of normal mortar, normal mortar pumice, and pumice mortar were 0,16 MPa,
0,10 MPa and 0,12 MPa. The analysis results show that the optimum split tensile strength
occurs in normal mortar pumice. Therefore, the effective proportion mix of mortar with using
pumice breccia is 1PC: 3PS: 3PM.
Keywords: Mortar, Pumice, Split Tensile Strength
