Thermal and Strength Performance of Two Lightweight Mortar Products

Author ALASTAIR W STUPART*JAYA S SKANDAMOORTHY**and FRANK EMERSON*** *BRE Scottish Laboratory**BRE Centre for Masonry Construction ***Tilcon (South) Limited Abstract Lightweight mortars contribute to reduced heat transmittance of walling by their low volume densities,...

Compressive Strength of Mortars Under Tri-axial Compression

Author HUMBERTO RAMOS ROMAN and GIHAD MOHAMAD Federal University of Santa Catarina Abstract The way to increase the efficiency of masonry seems to be to understand fully the mortar behaviour inside the joint. It does not seem reasonable to accept that stronger units...

Tests on Panels of Full Size Bricks at Different Loading Angles

Author STEPHEN POLLARD and BRIAN HOBBS University of Teesside Abstract This paper describes the first results of tests on panels of full size bricks to compare with previous work on the compressive strengths and failure mechanisms of panels of model bricks loaded at...

Effect of Loading Age on Creep of Sealed Clay and Concrete

Author J.P. FORTH*, PR. BINGEL* and J.J. BROOKS** * Leeds Metropolitan University ** The University of Leeds Abstract Test data on the influence of age at loading on the long term movements of clay brick and concrete block masonry walls under conditions which prevent...

The Effect of Rendering on the Flexural Strength of Brickwork

Author ANDRE P. EIDELWEIN and RONALDO B. DUARTE UFRGS, Brazil Abstract This paper gives the results of 72 tests on wallettes to study the influence of rendering on the flexural tensile .strength of brickwork walls. The variables considered are the type of brick and...

Anisotropy of Elasticity and Time-dependent Movement of Masonry

Author J.J. BROOKS and B.H. ABU BAKAR University of Leeds Abstract The deformation of masonry walls loaded in two directions, that is perpendicular to the bed and header faces, has been compared. Experimental test data are reported for a test duration of 220d for clay...

Internal Fracture Test for Brick Strength

Author LIU HUP and R.C. DE VEKEY** *Sichuan Institute of Building Research** Building Research Establishment Abstract This is part of a co-operative research programme between the BRE, and SIBR, China. Pull-out data were obtained using prisms I brick deep x 1.5 brick...

Compressive Strength of Clay Block Prisms

Author H.R. ROMAN and R.J.K. MENDES Federal University of Santa Catarina, Brazil Abstract Most of the research on structural masonry deals with solid clay bricks or concrete blocks. Very little has been done on hollow clay blocks. This paper describes the physical and...

Simple Test for the Determination of Masonry Flexural Bond Strength

Author F.M. KHALAF Napier University, Edinburgh Abstract BS5628 describes the testing of brick wallettes under four point loading as a standard test for the determination of flexural bond strength of masonry bed joints. The test provides an index of wall strength...

Soil Stabilised Blocks for Low-income Houses

Author RUBINA NOOR SHAIKH and RAID HANNA University of Glasgow/Mackintosh School of Architecture Abstract Earth is one of the earliest construction materials for human shelters. In its original form it does not meet the basic requirements for construction material,...

New Tests for Brick Porosity and Water Absorption

Author A.S. DeVENNY and F.M. KHALAF Napier University, Edinburgh Abstract The porosity of brick, its permeability and absorption are important factors in influencing such properties as the bond between it and mortar, the resistance to freezing and thawing and also its...
