Read MoreThe names for these mortar types, developed in 1954, were based on alternating letters of the phrase MASON WORK . Type M mortar has the highest strength. Type K mortar has the lowest compressive strength. The Appendix of ASTM C270 provides a reference to which mortar type should be used in some general applications.
Read MoreThe compressive strength of geopolymer mortar decreased from 35.60.4 MPa to 341.3 MPa after immersion in acid solution for 6 weeks as shown in Fig. 3. The decrease of geopolymer mortar compressive strength by 4.5 was lower than the decrease of OPC mortar compressive strength by 23.8, i.e. from 21.42.9 MPa to 16.30.9 MPa.

The 1.3 times of the average value of three specimens was taken as the compressive strength of the mortar accurate to 0.1 Mpa.
Read MoreMay 04, 2019 Mortar compressive strength is influenced by mortar water content at the time of set. Because molded mortar specimens are not in contact with absorptive masonry units and are not subjected to other mechanisms of water loss, they have a higher water content than mortar in the masonry. Higher water content results in lower compressive strength.
Read MoreThe Table also shows the percentage increase in compressive strengths for cube mortar specimens compared to a 38-inch specimen. For all cases, except for Type N mortar with a 5.1-inch flow, the compressive strength more than doubled when comparing cube strength to the typical mortar joint 38-inch-thick specimen strength.
