Brick-Mortar Bond and Masonry Compressive Strength

Abstract: This paper focuses on some issues pertaining to brick-mortar bond and masonry compressive strength Failure theories for masonry under compression make the assumption that the bond between brick and mortar remains intact at the time of failure of the brick or mortar The influence of bond strength on masonry compressive strength is not fully accounted for in these failure theories In this investigation, the influence of bond strength on masonry compressive strength has been examined through an experimental program using local bricks and mortars Masonry prism compressive strength has been determined when the brick-mortar bond strength is varied over a wide range without altering the strength and deformation characteristics of the brick and mortar Brick-mortar bond strength has been determined through flexure bond strength and shear bond strength tests A relationship between the masonry prism compressive strength and bond strength has been obtained The results clearly indicate that an increase in bond strength, while keeping the mortar strength constant, leads to an increase in the compressive strength of masonry

Strength and elasticity of brick masonry prisms and wallettes under compression

Abstract: The characteristics of brick masonry are influenced by the properties of bricks and mortar. This paper attempts at studying the properties of brick masonry using table moulded bricks and wire-cut bricks of India with various types of mortars. The strength and elastic modulus of brick masonry under compression have been evaluated for strong-brick soft-mortar and soft-brick strong-mortar combinations. Various sizes of prisms and wallettes have been tested during these experiments to study the size effect and different bonding arrangements. The failure mechanisms of such specimens have been studied. Attempts are also made to derive empirical relationships for masonry strength as a function of brick and mortar strength in the Indian context.

Life cycle assessment (LCA) and life cycle energy analysis (LCEA) of buildings and the building sector: A review

Abstract: This review summarizes and organizes the literature on life cycle assessment (LCA), life cycle energy analysis (LCEA) and life cycle cost analysis (LCCA) studies carried out for environmental evaluation of buildings and building related industry and sector (including construction products, construction systems, buildings, and civil engineering constructions). The review shows that most LCA and LCEA are carried out in what is shown as “exemplary buildings”, that is, buildings that have been designed and constructed as low energy buildings, but there are very few studies on “traditional buildings”, that is, buildings such as those mostly found in our cities. Similarly, most studies are carried out in urban areas, while rural areas are not well represented in the literature. Finally, studies are not equally distributed around the world.
