PREPARATION OF BRICK EARTH
Removal of loose soil:
About 30 cm depth contains a lot of impurities
like organic matter and hence
it should be taken out and thrown away.
Digging, spreading and cleaning:
The earth is then dug out from the ground.
This earth is spread into heaps
about 50 to 150 cm height.
Weathering:
The earth is then exposed to atmosphere for softening.
The period may be Of
few weeks to a season.
Hand moulding
When moulding is done with hand it is called hand moulding.
A wooden rectangular mould made in the shape of a brick is normally used for this purpose.
Machine moulding
The clay is placed in the machine, it comes out through the opening Under pressure.
It is cut to bricks by steel wires fixed into frames.
These bricks are also called wire cut bricks.
DRYING OF BRICKS
contain 7 to 30 percent moisture, depending upon the
forming method.
most of this water is evaporated in dryer chambers
temperatures about 100 ºF to 400 ºF (38 ºC to 204 ºC).
time, is between 24 to 48 hours.
Heat and humidity must be carefully regulated to avoid cracking in the brick.
BURNING OF BRICKS
INTERMITTENT KILN
Highly inefficient & labor-intensive.
Use coal + scavenged fuels
Most common, most primitive, most polluting
Temporary Structures
High Alumina Bricks High alumina bricks from 50% up to 90% alumina
Various selected superior grade aggregates to meet the various service conditions of various types of furnaces like laddie, blast furnace, cement and sponge iron rotary kiln.
Concrete Bricks
These bricks have either pale green or gray color.
these are prepared from a small, dry aggregate concrete which is formed in steel molds by using vibration and compaction.
Fire Brick
A Fire brick is a block of ceramic material
used in masonry construction and sized to be layer with one hand using mortar.
bricks may be made from type of material .
these are built primarily to withstand high heat and also find applications in extreme mechanical, chemical, or thermal stresses.
the brick is widely used as refractory insulating bricks for maintaining insistent temperature.
Light Weight Hollow Blocks
This blocks are used in construction of houses in earthquake prone areas.
These bricks are made of fly ash, cement, lime, gypsum, stone dust etc.
available in different sizes.
hollow concrete blocks is used as substitute for conventional bricks or stones used in construction of buildings. and the blocks' importmant feature
Joints are easy to maintain and are less detrimental than uncontrolled or uneven cracks. Concrete expands & shrinks with variations in moisture and temp. The overall affinity is to shrink and this can cause cracking at an early age. Uneven cracks are unpleasant and difficult to maintain but usually do not affect the integrity of concrete.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

colour, surface texture, density, weight, absorption, and pore
structure, thermal characteristics, thermal and moisture
movement, and fire resistance.
•The Indian standard size of a brick is 230-240 x 112-118 x 71-75.
•The minimum crushing / compressive strengths of
burnt bricks tested flat-wise prescribed are:
(i) Common building bricks—35 kg/sq. cm,
(ii) Second class bricks—70 kg/sq. cm,
(iii) First class bricks— 105 kg/sq. cm
