Abstract: Traditional building materials provide valuable information on the past of ancient and historical buildings. Studies on the characterisation of such materials provide information on the origin of raw materials, manufacture and building technologies, or decay of materials. Also, they provide information on different building phases and periods chronology. Among traditional materials, bricks and mortars are particularly interesting. One of the most useful information provided by bricks and mortars is the possibility of date them relative and absolute dating.

Also known as Sussex bond, this is a version of Flemish bond that served the same function as English garden wall bond. It is made by using one header brick.
Previously considered to be an inferior material to stone, brick construction was rarely used in Britain until the close of the Middle Ages. Gerard Lynch looks at its historical development over the last years and its conservation and repair. This was a direct result of lack of local stone, an increasing shortage of good timber, and the influence of Europe where brickwork was used extensively.
By the Tudor period the brick-makers and bricklayers had emerged as separate craftsmen well able to rival the masons. From unsophisticated early work, brick building entered its heyday, rivalling stone in its popularity as a structural material. Bricks were generally made on site in wood, heather or turf fired clamps by itinerant workers. Not only were standard bricks produced but also many in extravagant and elaborate shapes, epitomised by those that formed the spiral twisted chimney stacks for which the period is renown.
The Tudors further patterned their brickwork by inserting headers of over burnt or vitrified bricks into the walling. These dark surfaces ranging from deep purple to slate in colour, were laid carefully in quarter brick offsets in mainly English bond or English cross-bond, to form a diaper or chequered pattern within the predominantly red brickwork. Tudor bricks were irregular in size and shape and therefore thick mm mortar joints were necessary to even these out.
The slow setting mortar was of matured non-hydraulic lime often containing particles of the fuel used in its production , and coarse sand in a ratio varying from , the joints being finished flush from the laying trowel.

A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term brick denotes a block composed of dried clay , but is now also used informally to denote other chemically cured construction blocks. Bricks can be joined together using mortar , adhesives or by interlocking them. Block is a similar term referring to a rectangular building unit composed of similar materials, but is usually larger than a brick.
Lightweight bricks also called lightweight blocks are made from expanded clay aggregate. Fired bricks are one of the longest-lasting and strongest building materials , sometimes referred to as artificial stone, and have been used since circa BC. Air-dried bricks, also known as mudbricks , have a history older than fired bricks, and have an additional ingredient of a mechanical binder such as straw.
Bricks are laid in courses and numerous patterns known as bonds , collectively known as brickwork , and may be laid in various kinds of mortar to hold the bricks together to make a durable structure. The earliest bricks were dried brick , meaning that they were formed from clay-bearing earth or mud and dried usually in the sun until they were strong enough for use. The oldest discovered bricks, originally made from shaped mud and dating before BC, were found at Tell Aswad , in the upper Tigris region and in southeast Anatolia close to Diyarbakir.

Brick-work is so common that we don’t give it a second thought. What could be less interesting than a brick, you might think! But brickwork evolved to meet the needs of society, and over the centuries it has continually responded to changing needs, technology and fashions. The Romans had bricks, but they were very different from what we think of as a brick today. Brickwork as we know it was imported from the low countries in the middle ages.

Man has used brick for building purpose for thousands of years. Bricks date back to BC, which makes them one of the oldest known building materials. They were discovered in southern Turkey at the site of an ancient settlement around the city of Jericho. The first bricks, made in areas with warm climates, were mud bricks dried in the sun for hardening. Ancient Egyptian bricks were made of clay mixed with straw.
The evidence of this can be seen today at ruins of Harappa Buhen and Mohenjo-daro. Paintings on the tomb walls of Thebes portray Egyptian slaves mixing, tempering and carrying clay for the sun dried bricks. The greatest breakthrough came with the invention of fired brick in about 3, Bc. From this moment on, bricks could be made without the heat of sun and soon became popular in cooler climates.

Fired clay ceramics start to react chemically with atmospheric moisture as soon as it is removed from the kiln. Researchers believe they can pinpoint the precise age of materials like brick, tile and pottery by calculating how much its weight has changed. The team from Edinburgh and Manchester universities hope the method will prove as significant as radiocarbon dating.
Radiocarbon dating, used for bone or wood, cannot be used for ceramic material because it does not contain carbon. He and his team, from the universities of Edinburgh and Manchester and the Museum of London, were able to date brick samples from Roman, medieval and modern periods with remarkable accuracy. They have established that their technique can be used to determine the age of objects up to 2, years old but believe it has the potential to be used to date samples around 10, years old.

LexEva is a newly released evaluation software developed for analysis in luminescence research and dating. While the typology of ceramics is a backbone of many archaeological chronologies, establishing the age directly for certain types of ceramics is sometimes required.
Although luminescence dating is currently applied on fired bricks, and lime mortars have been dated in recent years (Sanjurjo-Sánchez,
Bricks and concrete blocks are some of the oldest and most reliable of building products. Bricks were first used 5, years ago and were made from dirt using straw as a binder. Later bricks were made from clay and fired in a kiln to increase their durability. The history of concrete blocks dates back to ancient Greece and Rome, although they were not manufactured commercially until the early 20th century.
Dating old brick and block is not a precise science, but there are a few things to look for. Examine the surface of the brick. Old bricks were formed by hand, so look for irregularities in shape. They should be slightly uneven and may contain straw. These older hand-shaped bricks are larger than the bricks made today, although never larger than a hand width.
Look for an indentation on the brick’s surface. Older bricks do not have a dent in the middle, called a frog.

Dating buildings is important for survey reports: particularly for conservation appraisals, archaeological assessments, and for predicting age-related latent defects, such as Georgian ‘snapped-header’ walls, inter- wars ‘Regent Street Disease’, or post-war high-alumina cement concrete deterioration1. When a building is original, and typical of its period, its age can usually be judged by its external appearance alone. Every era has its distinctive architectural styles, ranging from wavy roofs of the s, to bow-backed Georgian terraces of the s.
But when a building is nondescript, atypical a folly , has been altered, extended or overclad, we need to examine its structure.

Roasting ancient building materials might help archaeologists to date them 1. Bricks swell very slowly as they age, because they absorb moisture. Heating dries them out. How much they shrink indicates how old they are because it is proportional to how long they have been wicking up water, argue Moira Wilson of the University of Manchester Institute of Science and Technology, UK, and colleagues. The researchers performed a series of experiments with new and old bricks.
Next, they artificially aged new bricks by exposing them to very hot steam. A few hours’ steaming seemed to have a similar effect to a few centuries of normal ageing.
