Fire rings have no bottom, and are simply circles made of forged metal, stones, concrete, etc. which ...
John Smeaton FRS (8 June 1724 – 28 October 1792) was an English civil engineer responsible for the design of bridges, canals, harbours and lighthouses. [1] He was also a capable mechanical engineer and an eminent physicist. Smeaton was the first self-proclaimed "civil engineer", and is often regarded as the "father of civil engineering". [2]
There he introduced a new and substantially stronger cement, using a modified recipe for cement-making, the first "modern" Portland cement. [4] In 1844 Joseph retired, transferring his share of the business to James. James moved to a third site at Ings Road in 1848, and this plant continued in operation until 1900.
Although different forms of cement already existed (Pozzolanic cement was used by the Romans as early as 100 B.C. and even earlier by the ancient Greek and Chinese civilizations) and were in common usage in Europe from the 1750s, the discovery made by Aspdin used commonly available, cheap materials, making concrete construction an economical ...
Fire also played a major role in changing food habits. Cooking allowed a significant increase in meat consumption and calorie intake. [34] It was soon discovered that meat could be dried and smoked by fire, preserving it for lean seasons. [35] Fire was even used in manufacturing tools for hunting and butchering. [36]
Engineers created a breakthrough cement that's 17 times stronger, leading to safer and more durable buildings. And they used an astonishing secret weapon. Engineers Discovered the Spectacular ...
TIL Marcus Licinius Crassus, often called "the richest man in Rome," formed the first fire brigade, saving burning buildings only if owners sold at a low price. Otherwise, he let them burn.
In 1875, the first iron-reinforced concrete bridge ever built was constructed at the Castle of Chazelet. Monier was the designer. The important point of Monier's idea was that it combined steel and concrete in such a way that the best qualities of each material were brought into play. Concrete is easily procured and shaped.
