Stack Bond A brick or masonry bond where the all members are aligned vertically. There is no staggered effect or overlapping. Also known as Stacked Bond
What is a stacked bond?
A brick or masonry bond where the all members are aligned vertically. There is no staggered effect or overlapping. Also known as Stacked Bond I guess it still is called a bond, but if you were stack dry bricks or blocks like this then the stack would not get too high before starting to lean.
What is the difference between a running bond and stack bond?
The running bond is about twice as strong in flexure when spanning horizontally as when spanning vertically. Meanwhile, stack bond walls have approximately the same strength regardless if spanning vertically or horizontally having the joints aligned in either direction. So what does this mean?
Is it possible to use stack bonding in structural walls?
Even then, with stack bonding it is always advisable to use extra bed reinforcement. The photo above is of modular concrete blockwork, which with it's internal reinforcing and it's other mesh reinforcing along the bed joints would make it possible to use this bond in structural walls.
What is the wall strength of a vertical stack bond?
Units laid in the vertical or diagonal position generally produce wall strengths approximately 75% of that obtained from the running bond pattern. The reduction in strength for vertical stack bond is directly related to the decrease in net block area in compression.
What is stack bond in construction?
The technical definition of stack bond is any wall where the overlap of a masonry unit over the block below is less than one quarter of the length of the block.
What is stack bond and running bond?
The running bond is about twice as strong in flexure when spanning horizontally as when spanning vertically. Meanwhile, stack bond walls have approximately the same strength regardless if spanning vertically or horizontally having the joints aligned in either direction.
Is stack bond strong?
From this it can be seen that properly reinforced stack bond masonry can be designed to be as strong as running bond construction.
What is stack bond brickwork?
In stack bond, bricks are laid directly on top of one another with joins aligned, running vertically down the entire wall. Bricks can either be stacked horizontally or vertically.
Why do bonds stack?
Stack bond (or stacked bond) This bond visually emphasises the vertical aspect of the masonry. The facing bricks are laid one on top of the other so that not only the horizontal edge joints, but also the vertical head joints are continuous. This can be done with stretchers as well as with headers.

What bond should be used for Blockwork?
English bond (also known as Ancient Bond) requires quarter bond work in its construction of a course of stretcher bricks and a course of header bricks laid alternately. This type of bond is the strongest brickwork bond. It is however, one of the most expensive because of the labour time.
Which is the strongest bond in brickwork?
English Bond The English brick bond alternates rows of headers with rows of stretchers. This type of wall-building uses more bricks than a stretcher bond, so is rarely used for largescale residential developments, but it is often considered one of the best and strongest brick bond designs around.
How many types of bonds are in brickwork?
There are five basic structural bonds commonly used today which create typical patterns. These are: Running bond, common or American bond, Flemish bond, English bond and block or stack bond, as illustrated in Fig.
What is the strongest brick pattern?
The strongest of the patterns is the herringbone. It can be laid at a 45 or 90 degree angle. The pattern has many angles that can be described as energetic, and can truly engage your visitors as they make their way to the entrance of your home.
How do stack bond bricks work?
In a stack bond the bricks are literally stacked on top of each other and held by mortar. It can look effective, but there’s no strength in the wall. If a stand bond wall is going to stand it will need to be secured to a metal plate at the back or be supported in some other way. That’s its great drawback. If just used for decoration it can look excellent and act as a focal point for the eye. For construction, however, the running bond wins.
What bond to use to stack bricks?
Bricks can be stacked in a variety of ways, but typically there are only two common options when it comes to installing bricks: The running bond and the stack bond.
Why is the running bond so common?
The running bond is common because it’s easy to execute and does exactly what it’s supposed to do, even if it doesn’t look especially dramatic.
INTRODUCTION
Varying the bond or joint pattern of a concrete masonry wall can create a wide variety of interesting and attractive appearances using standard units as well as sculptured-face and other architectural units.
STACK BOND CONSTRUCTION
Excluding running bond construction, the most popular and widely used bond pattern with concrete masonry units is stack bond. Compressive strength is similar for stack and running bond construction.
CODE REQUIREMENTS
Building Code Requirements for Masonry Structures (ref. 1) includes criteria for walls laid in stack bond.
TESTING PROGRAM
To assist in evaluating the structural performance of walls laid with various bond patterns, a large number of concrete masonry panels were tested for compressive and flexural strength (ref. 2). The nine bond patterns shown in Figure 2 were employed in constructing the test panels. Panels were composed of 8 in.
