Author D. LENCZNER and R. J. HARVEY University of Wales, Cardiff Abstract The creep behaviour of large scale concrete block masonry specimens under constant axial stress was investigated experimentally. A single type oj block and two strengths oj mortar were tested,...
Author J.J. BROOKS and J.P. FORTH University of Leeds Abstract Test data are reported for 160-day creep and shrinkage of 2-brick wide x 13-course high single leaf clay brickwork constructed from six types of unit having strengths ranging from 30 – 120N/mm2 and a...
Author B. MIDDENDORF and D. KNOFEL Laboratory for Chemistry of Construction Materials (BCS) University of Siegen Abstract The fabric of many historic brick buildings is in part heavily damaged. The paper gives mainly chemical and mineralogical results of analyses of...
Author MYRIAM OLIVIER and ZEKERIA EL GHARBI Laboratoire Geomateriaux de I’ENTPE, France. Abstract Since 1982 the Geomaterial Laboratory of ENTPE has carried out a scientific study of earth architecture in order to improve making techniques and to better...
Author DAVID, M. F. ORR. University College Cork and MARTIN P. MANNION, Regional Technical College. Cork Abstract It is difficult to obtain contact between block and mortar over the full width of the bed joints in masonry of solid concrete blocks laid flat on face....
Author HUMBERTO R. ROMAN and FRANCISCO T. NEGREIROS Universidade Federal de Santa Catarina, Brazil Abstract The paper describes part of a research project into the addition of either pulverized fuel ash (pfa) or furnace-bottom ash (fba) to clay for brick production....
Author BRUCE A. WIDEMAN Lafarge Corporation, Michigan. Abstract The 1991 edition of the Uniform Building Code (UBC)[1], the most commonly referenced of three model building codes in the United States, contains a specification for mortar cement. This, while similar to...
Author G. FRUNZIO, C.D’ONOFRIOand M. MONACO Universita degli Studi di Napoli “Federico II” Abstract An accurate study of ancient masonry structural behaviour involves mechanical characterization of components, mortars and stone units. As part of a...
Author CAIJUN SHI. ROBERT L. DAY and AR1E HUIZER The University of Calgary Abstract This paper deals with the effect of some sodium-based activators (Na2SO4 NaOH, Na2C03 and Na2SiO3.5H20) on strength development of two types of blended cements made with natural...
Author T. McNEILLY Consultant Architect Abstract After a short account of the 140 year history of the gradual adoption of cavity construction in Australia, the paper, which is mostly anecdotal, describes the watertightness fortunes of the 186O’s solid nine inch...
Author PS. HAZAEL CeIcon Blocks Limited Abstract Substantial amounts of Aircrete are used in the U. K. for the inner leaves of cavity walls. These are essentially used as clear cavity solutions to meet the relevant Standards and Regulations. Aircrete is also used in...
Author R. C. de VEKEY Building Research Establishment Abstract The history of the introduction and spread of the cavity wall is reviewed in the light of the reasons for it’s use and its performance in relation to the job it has to perform. Its strengths,...
Author PROFESSOR J J. ROBERTS Kingston University Abstract This paper discusses the relative benefits of different forms of masonry external wall construction, including some previously unpublished results from site monitoring. Observations are made on the thermal...
Author D. FOSTER Consultant Architect Abstract In the I9th and early years of this century millions of two storey houses having single leaf one brick thick external walls were built. Many still survive giving adequate resistance to rain penetration but poor thermal...
Author Professor Emeritus A.W. HENDRY University of Edinburgh Abstract This paper summarises the results of a number of investigations into the structural behaviour of cavity walls as revealed by wall tests and by tests designed to examine the interaction between...
Author B. GILLINSON Institute of Advanced Architectural Studies University of York Abstract The most significant error in recent years is the use of masonry in a semblance of its natural and traditional ways, but for non-traditional and illogical purposes to clad the...
Author J. MINDENHALL Halfen Fixing Systems Abstract The fixing specialist’s viewpoint is that there is no need to reconsider the use of single skin brickwork in favour of traditional thicker loadbearing construction. A single skin of brickwork cladding to an...
Author B. BIRD Whitby and Bird Abstract These examples are not reuses of traditional one brick thick walls. They are uses which satisfied modem construction constraints whilst achieving classical elevations with a proper depth of relief. Use of movement joints was...
Author Ir. G. PEERS Brussels Abstract Cavity walls are very popular in the northwestern part of Europe and are commonly considered the answer to the rain penetration problem of unprotected brick walls. In practice, the name “cavity wall” covers a wide...
Author S.E. BELL and M.E.A. BACKHOUSE Marshalls Clay Products Abstract The concept of using brickwork in some building forms as a thin skin cladding is flawed. Such skins are vulnerable to wind and other forces and limit aesthetic design. Design and construction...
