egarding the compressive, tensile, shear, and bond strength properties of the mortar used in construction. The purpose of the Mortar Bond Strength test is to determine the bonding properties between a mortar mix and set of blocks. Test prisms are constructed by bonding two blocks with the top block oriented 90 degrees to the bottom block. The mortar‟s Bond Strength is determined by loading the block prism into a load frame and testing to failure as per ASTM C 952-02. The mortar‟s tensile bond strength is calculated with the following equation. P f Pf [ psi] A force at failure A Area of mortar [ in lbs Figure 6.1: Mortar Bond Strength Test Set-up The purpose of the Mortar Shear Strength test is to determine the bonding properties between a mortar mix and set of blocks when tested in shear. A test prism is constructed (horizontal orientation: Figure 6.2.a) with the middle block offset by 2”. After being allowed to cure, the prism is placed into a load frame (vertical orientation: Figure 6.2.b) and tested to failure. To determine the mortar‟s shear strength, the following equation is used: 2 ] 82
