Author DAVID M F ORR AND JOHN COSTELLOE, University College Cork Abstract A bond wrench apparatus has been developed for testing bed joints between solid concrete block masonry units. The apparatus has been used to obtain data for an investigation into the effect of...
Author ROB VAN DER PLUIJM, HARRY S. RUTTEN, AND COR S. SCHIEBROEK Eindhoven University of Technology Abstract The main variable in the experimental research with masonry wallettes tested in flexure, was the angle between bending axis and bed joints. Two types of...
Author U. MEYER Arbeitsgemeinschaft Mauerziegel e.V., Bonn and P. SCHUBERT Institut fur Bauforschung, Aachen Abstract Flexural tests on reinforced perforated clay unit masonry (vertical holes >35%) under monotonic and cyclic loading have been carried out at the...
Author C. SOUTHCOMBE University of Plymouth I.M. MAY Heriot-Watt University and V.L. CHONG China Institute of Technology and Commerce Abstract The paper presents the results of an experimental investigation into the behaviour of laterally loaded, single leaf and...
Author G.KONIG1, A.OTES2 and M. ERNST1 1 Technische Hochschule Darmstadt 2 Ingenieurburo Konig & Heunisch, Frankfurt Abstract This paper gives the first results of tests on unreinforced and reinforced masonry walls with openings. The walls were built with...
Author MATTHEW GILBERT University of Sheffield, and BRIAN HOBBS University of Teesside Abstract This paper describes the ongoing programme of impact testing on full-scale unreinforced masonry walls constructed in the laboratory at the University of Teesside. A novel...
Author W.A.FERGUSON Building Research Establishment and G.J.EDGELL British Ceramic Research Limited Abstract The performance of laterally loaded masonry is normally measured by static loading, using airbags. It has been suggested that it might be enhanced if the load...
Author A.N. FRIED and D.W. LAW Kingston University Abstract This paper examines the relationship between a number of mortar and unit properties and the bond strength of masonry. The water absorption, suction rate, crushing strength and dry density of the units are...
Author J.P. FORTH Metropolitan University of Leeds and J J. BROOKS University of Leeds Abstract Previous investigators have shown that for certain types of clay brick, the horizontal irreversible moisture expansion of the clay brick masonry can be related to the...
Author N.TUBI, F.CANTONI, A FANTUCCI AND G.ZANARINI ICITE-CNR, Italy Abstract Wallettes were built of hollow clay blocks (40,50 and 55% holes) alt produced in the same plant from the same raw materials and process. The wallettes were loaded vertically (perpendicular...
Author HEINRICH METZEMACHER Industrieverband Werktrockenmortel e.V., Koln Abstract In order to evaluate the resistance of masonry to cracking in the presence of slowly developing restraint forces, information is needed on the level of stress imposed and the...
Author T.G. HUGHES AND R.J. HARVEY University of Wales, Cardiff Abstract In a normal environment, masonry constructed from fired clay units will expand as moisture is taken into the dry units from their surroundings; this expansion can lead to considerable compressive...
Author C.S. ABDULLAH, R. ANANG AND M.S. YASSIN Universiti Teknologi Malaysia Abstract An experimental programme was undertaken to study the effect of incorporating palm oil ash (POFA) and rice husk (RHA) on the properties of fired clay brick. Tests showed that clay...
Author A.I.G.YOOL AND T.P.LEES Green Land Reclamation Limited Abstract Sieve gradings (including fines contents), methylene blue adsorption values and sand equivalents of spot samples of 154 buildings sands, taken from throughout the United Kingdom, are presented...
Author M. OLIVIER and Z. EL GHARBI ENTPE, France Abstract Studies in the Geomaterials Laboratory of ENTPE on “Earth as a building material”, showed that, unlike concrete block masonry, the weak point in earth block and earth mortar masonry, loaded...
Author PETER WALKER University of New England, NSW. Abstract The paper presents results of uniaxial and concentrated compression load tests on stabilised soil block walls. Strip toads were applied both centrally and on edge, with loaded area ratios varying between...
Author C. D’ONOFRIO, G. FRUNZIO and M. MONACO Universita degli Studi di Napoli “Federico II” Abstract The properties of Neapolitan yellow tuff, a frequently used building material from ancient times to the present, have been determined as specimens...
Author G. DE CASA and G. SAPPA University “La Sapienza”, Rome. Abstract The long history of this widely used building stone and its architectural uses in historic buildings are briefly described. The growing need for technical intervention for conservation...
Author R.C.DE VEKEY and K.TARR Building Research Establishment Abstract The objective of this series of tests was to measure any change in performance resulting from relaxation associated with mechanically fixed metal expansion anchor type wall ties. Two makes of...
Author STEPHEN L GARVIN AND IAN H MURRAY Building Research Establishment, Scottish Laboratory Abstract A test programme is described to assess the suitability of the BRE general purpose mortar (GPM) for Aircrete blockwork, in particular to assess the effect on...
