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discusses the relative benefits of different forms of masonry external wall construction, including some previously unpublished results from site monitoring.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...
Author R.J.M. SUTHERLAND Consultant, Harris & Sutherland Abstract Masonry has changed markedly in the last 100 years both in its use and in its form. The question is whether all the changes have been for the good or whether we have taken some wrong turnings....
Author R. C. DE VEKEY*, G. J. EDGELLt and R. DUKES** *Building Research Establishment, Garston, UK **British Ceramic Research Limited, Stoke-on-Trent, UK Abstract The current British Standard for sands for masonry mortars includes an S (structural) grade and a finer G...
Author E. KJAER The Danish Brick and Lime Laboratory Abstract As masonry walls become more slender the adhesion between bricks and mortar is more important. Tests have been carried out to determine the flexural strength of wallettes made from 16 clay brick types and...
Author TERENCE A. WEIGEL University of Louisville, Kentucky Abstract In 1988, a new code, covering the design of both clay and concrete masonry, was introduced in the United States. This code replaced a variety of existing codes, one of which addressed the design of...
Author R. S. NARAYANAN S. B. Tietz & Partners J. MORTON Brick Development Association Abstract The Brick Development Association commissioned S. B. Tietz & Partners to conduct a parametric design study of a 10-storey building. Using EC6 and BS 5628 the study...
Author S. K. ARORA Building Research Establishment, Garston and M. J. BLACKLER Mott MacDonald Group Abstract The European Commission has issued draft Eurocodes (EC) for the design of structures which need to be subjected to national examination and comment by the UK...
Author G. J. EDGELL*, R. C. DE VEKEY** and R. DUKES* *British Ceramic Research Limited **Building Research Establishment Abstract Storey height and half-storey height walls, wallettes and stack bonded prisms were built in one of seven bricks, four blocks and three...
