Grimm, C T (1994) Void mortar joints: Bane of brick masonry. Journal of Construction Engineering and Management, 120(1), pp. 152-161. ISSN 0733-9364
Abstract
The adverse effects of void mortar joints on the performance of masonry are enumerated. Unfilled mortar joints in brick masonry weaken walls, increase leakage, breach a contract, violate the law, and break tradition. The bricklayers union, masonry contractors, architectural and engineering professionals, and materials researchers all agree that unfilled mortar joints should not be permitted. At least since 1890 the literature on masonry has been replete with admonitions on the necessity for filling mortar joints. Masonry may turn out unintentionally bad, but it will never be accidentally good. Inspection of masonry under construction is now required by building codes and specifications promulgated by The Masonry Society, the American Society of Civil Engineers, and the American Concrete Institute (“Specifications” 1988). A method for measuring void joints is described. The unaided human eye is a satisfactory instrument for judging mortar joint solidity. Photographs of typical unfilled joints are shown. The pervasive lack of concern for poor masonry workmanship can lead to undesirable legal consequences.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
