Concrete Blocks

Masonry , the art and craft of building and fabricating in stone, clay, brick , or concrete block. Construction of poured concrete , reinforced or unreinforced, is often also considered masonry. The art of masonry originated when early man sought to supplement his valuable but rare natural caves with artificial caves made from piles of stone. Circular stone huts, partially dug into the ground, dating from prehistoric times have been found in the Aran Islands , Ireland. By the 4th millennium bce , Egypt had developed an elaborate stonemasonry technique, culminating in the most extravagant of all ancient structures, the pyramids. The choice of masonry materials has always been influenced by the prevailing geological formations and conditions in a given area. Egyptian temples, for example, were constructed of limestone , sandstone , alabaster, granite , basalt, and porphyry quarried from the hills along the Nile River.

The present invention relates to the concrete protection piece of monobloc cast, the safeguard structure with in Yu Haiyang and the River Engineering to resist wave and current, also relates to the mould that is used to make this concrete block. The technical characterstic that this artificial piece will satisfy is: stable and firm in water. Except these technical characterictics, the designer’s of concrete block purpose is to reach outside desired stability of use and the fastness, reducing by a needed concrete amount of definite overcoat.

For this reason, the designer adjusts the size and the angle of concrete block configuration part, so that increase the space between the staggered concrete block.

Dating back to the s, breeze blocks, or architectural screen blocks As you’​ve probably noticed, these concrete blocks became wildly.

Breeze blocks are having a moment in the sun. Having been painfully hip in the architecture of the s and 60s, they were used so extensively, in both houses and commercial buildings, that they became ubiquitous anywhere in the world where it was hot — including throughout Australia. While particularly associated with a beachy, holiday feeling — Gold Coast motels, houses in Palm Springs — they were really so widely-used that they can still be found pretty much everywhere.

But after that postwar high point, they fell drastically out of favour, and languished for the next fifty years, built into the walls and gardens of our youths, widely loathed and reviled for being ugly and out of date. Marshall has been collecting images of breezeblocks for sixteen years, and has more than nine thousand followers.

Patterned concrete blocks have a long and sometimes celebrated lineage. The breeze block can also be linked more broadly to the tradition of the brise soleil , which refers to any kind of sun baffle installed outside the skin of a building which is where the sun screens should be!

More buildings. More opinion. With the fall of the Roman Empire the dating of concrete making block largely lost until the late s when lime concrete was rediscovered in the uk. But this became obsolete by the s with the advent brick Portland concrete. In , W B Wilkinson patented reinforced concrete. In he built what was probably the first brick concrete house, which stood dating Newcastle until demolished in.

Wilkinson’s invention did not apparently progress. Reinforced concrete technology was developed date continental engineers and block brick to the uk in the s. It became attractive to engineers and architects alike, for its cracks of form, fire resistance, and high tensile strength. Apart from Ordinary Portland Cement opc Concrete, other concrete mixes have been used throughout the last hundred years brick date properties, such as lightness or rapid hardening. They can sometimes be distinguished by their colour and texture see table below.

From the advent of Parker’s Roman cement in until the inception of reinforced concrete in the s, mass unreinforced brick was block for components of buildings, such as footings, ‘fireproof’ flooring, underpinning, dating artificial stone bay-windows. With a few exceptions1, mass concrete was not used to construct whole buildings.

Terrible fires in warehouses and factories during the industrial revolution produced a demand for fireproof floors.

Abstract: This thesis outlines the early developmental history of concrete block in America with special attention being placed on the years leading up to the St. Louis Louisiana Purchase Exposition of In general, the history of concrete block in contemporary building material histories begins with the innovations in block machinery that took place at the turn of the 20th century.

However, the history of concrete block begins much earlier than these innovations.

Ever wondered what sparked the mid-century modern infatuation with those concrete blocks with decorative cutouts that surround so many traditional homes? Dating back to the s, breeze blocks, or architectural screen blocks offer a decorative screen wall or fence with an architectural appeal. Both residential and commercial buildings started to use breeze blocks with decorative hole patterns within their design.

Breeze blocks are often made from ashes of coal. They are bonded together with Portland cement and often used for walls bearing smaller loads. While we may associate breeze blocks more with mid-century modern designs, they actually started in the Art Deco period. The s saw breeze blocks become a trend used in modern homes as a way to transition from building to yard. During the s, the suburbs started to embrace breeze blocks as a common fencing option.

Not only had these concrete blocks caught on in the suburbs, but also throughout commercial projects. Just about every coastal and warm climate across the globe started to embrace breeze blocks. They were used in residential and commercial projects throughout Australia, Brazil, Spain, the United States, and many other countries. While breeze blocks came on strong and were a popular design element throughout the mid-century modern period, the trend started to die off in the s.
