Mortar Testing

Mortar Testing

1. Field testing Mortar

   • The CSA A179 standard contains a test procedure to determine the ratio of aggregate to cementitious material in fresh mortar.
   • No. 100 sieve cementitious materials pass through the sieve and the aggregate is retained.
   • A balance of strength and bond is

2. Strength

   • CSA A179:  The PROPORTION METHOD, and  The PROPERTY METHOD
     • Proportion method is typical for site-mixed mortar
       • typically used unless the Property Method is specified
         • Property method is typical for premixed dry or wet mortar
     • aggregate size of sand! Small cubes are taken from each batch, molded and tested for suitable compressive strength table 5

3. 5” (125mm) for low absorption units.  8” (200mm) for high absorption units.  Glass blocks require a lower slump
