COMPRESSIVE STRENGTH VALUES FOR TYPE N MORTARS FOR CONSTRUCTION SITES

DURING THE PERIOD MID-1966 TO MID-1968, FIELD STUDIES WERE CONDUCTED AT THE ATLANTIC REGIONAL STATION, DIVISION OF BUILDING RESEARCH, ON THREE MASONRY CONSTRUCTION PROJECTS INVOLVING THREE DIFFERENT TYPE N MORTARS. THE STUDIES WERE DESIGNED, 1) TO OBTAIN DATA ON MORTARS MIXED ON THE JOB SITE, AND 2) TO EXPERIMENT WITH CERTAIN NEW FIELD TESTS. COMPRESSIVE STRENGTH TESTS ON 2-IN. CUBES AND 3-X 6-IN. CYLINDERS WERE ALSO INCLUDED IN THE STUDY. PROCEDURES AND REQUIREMENTS WERE THE SAME FOR BOTH TESTS. RECENT DEMAND FOR FIELD CONTROL TESTS FOR MORTARS, A RESULT OF INCREASING ACCEPTANCE OF THE LOAD-BEARING MASONRY WALL CONCEPT, HAS RESULTED IN THE INCLUSION OF A FIELD CONTROL TEST FOR COMPRESSIVE STRENGTH IN THE RECENTLY PUBLISHED CSA STANDARD A224, MASONRY CODE OF PRACTICE, AND THE CANADIAN STRUCTURAL DESIGN MANUAL (SUPPLEMENT 4 TO THE NATIONAL BUILDING CODE OF CANADA 1970). DURING PREPARATION OF THESE DOCUMENTS THERE WAS DISCUSSION ABOUT MEANINGFUL REQUIREMENT VALUES AND IT MAY, THEREFORE, BE HELPFUL TO COMPARE DATA FROM THE FIELD STUDIES WITH THE REQUIREMENTS FOR TYPE N MORTAR IN THE NEW STANDARDS.
