Experimental Data on Mechanical Behaviour of Lime Mortar

Author SILVIA BRICCOLI BATI and LUISA ROVERO Universita degli Stredi di Firenze Abstract Mechanical characteristics of lime mortars can readily be enhanced by the addition of components used historically prior to the introduction of Portland cement. A preliminary...

Masonry in the Third Millennium

Author GIOVANNI PEIRS Belgian Clay Brick Federation Abstract For millennia the technique of masonry construction has remained basically unchanged. Only since the last century can new types of masonry units, new types of mortar and new design forms be seen. Although...

Sustainable Masonry Construction

Author J.J.ROBERTS Kingston University Abstract This paper looks at the sustainablity of masonry construction in the context of the U.K. ‘s national sustainable development strategy. It identifies the key issues which need to be addressed in order to provide a...

Author CHE SOBRY ABDULLAH, MOHAMAD SALLEH YASSIN and ROSLI ANANG Universiti Teknologi Malaysia Abstract This paper presents the results of tests carried out on interlocking mortarless blockwork specimens to determine the required design data for the design of a...

Temperature Conditions of Masonry in a Severe UK Environment

Author MARK PHILLIPSON and ALASTAIR STUPART Building Research Establishment, Scottish Laboratory Abstract An analysis of temperature data recorded from various parts of walling exposed to natural weathering over two winters is described and related to both climatic...

Post-tensioned Brick Girders at Vernon Terrace, Northampton

Author L.N. ALLEN Nash Mynard Design Abstract To satisfy planning requirements and make the project economically viable, clear spans of up to 9m were necessary, supporting very heavy loads within a maximum theoretical structural zone at floor level, 250mm deep. This...

Macroscopic Defects Observed in Reinforced Brickwork Walls

Author S.W.GARRITY University of Bradford Abstract A survey of seven, 3m high reinforced cellular brickwork walls was carried out to identify any defects that might impair their long-term performance. The defects found included plastic shrinkage cracking, drying...

The Use of Parafil as a Prestressing Tendon in Prestressed Masonry

Author D.J. EASTERBROOK*, G. SHAW** and G. GILL* * University of Plymouth **Curtins Consulting Engineers Abstract The current vogue for structures which are tow cost, durable and maintenance free has led to engineers focusing on non-metallic structures. Current work...

Force Transfer from Carbon or Steel Reinforcement to Masonry

Author AD T. VERMELTFOORT Eindhoven University of Technology Abstract Either carbon or Aramid fibre rods or steel bars can be used to reinforce prefabricated single leaf masonry. Steel reinforcement will corrode hence the force transfer of carbon fibre rods to masonry...

Bed Joint Reinforcement in Masonry

Author P. TIMPERMAN and J.A. RICE, NV Bekaert, Belgium Abstract Reinforced masonry has been widely used in seismic areas over the past 75 years. This paper examines nonseismic uses and attempts to evaluate the economic benefits of bed joint reinforcement when used in...

The Effective Use of Masonry Reinforcement for Crack Repair

Author D. COOK, S. RING University of Bath and W. FICHTNER Institut fur Tragkonstruktionen, Universtat Karlsruhe Abstract The work is about the tolerance of “in-service” brick/masonry buildings to movement, the way they deform in. shear and bending and the...

Cracking Due to Restraint

Author UDO MEYER Arbeitsgemainschaft Mauerziegel e. V. Bonn Abstract Restrained movements due to shrinkage or thermal action are among the main reasons for cracking in masonry. Cracks due to restrained stresses parallel to the bed joints can be limited by bed joint...
