When did the cement house come into existence? How many years can you live in a cement house

In 1824, Portland cement was manufactured, which is now commonly used Portland cement, and cement began to be popularized later.

In 1774, engineer Smitton was commissioned to build a lighthouse in the English Channel to guide the navigation of passing ships. This stumped Smilton. Bricklaying with lime mortar under water?

As soon as the mortar sees the water, it becomes a thin field. Sinking into the sea with stones? How can it withstand the impact of the waves?

After countless experiments, he finally burned limestone, clay, sand, and iron slag with rice, crushed it, mixed it with water, and then injected it into the water, and the mixture was not diluted in the water, but became stronger and stronger. In this way, he finally built the first beacon lighthouse in the English Channel.

Soon, a stonemason named Yasputin in England found the most suitable proportion of lime, clay, iron slag and other raw materials, and further perfected the method of producing this mixture. In 1824, Yasputin was granted a patent for this invention. Because the color and strength of this gum material after hardening are very similar to the stone produced in Portland, he named it "Portland Cement".

Since then, the name of this man-made stone, the peculiar stone, "cement", has been used.

I heard that foreigners began to study the construction of ancient Chinese buildings, and opened to follow suit.

I don't remember if it's boiling glutinous rice or something.

1.How many years can you live in a cement house

Cement houses are a very common type of Zen in our modern architecture, and their main structural materials are a mixture of cement, sand, lime and other materials. Due to the characteristics of cement materials such as solidity, durability, and fire resistance, cement houses have a long service life.

2.What are the factors affecting the life of cement houses?

Although a cement house has a long lifespan, its longevity is also affected by many factors, including the foundation, structure, material quality, construction quality, and use and maintenance.

3.How to extend the life of cement house?

In order to prolong the life of a cement house, the following points should be paid attention to in construction and use:

Scientific site selection: Geological exploration should be carried out before the construction of the cement house, and a solid foundation should be selected to ensure the stability of the building.

High-quality materials: When building a house, we must choose good building materials, especially the quality of cement, to prevent saturation sampling and shell breaking.

Construction quality: The structural design and construction quality of the house are also very important, and the construction should be operated in accordance with the standards to avoid problems caused by unreasonable construction.

Daily maintenance: After the house is completed, it is necessary to check and maintain it frequently to prevent leakage and cracking of the cement house, and deal with the problem in time.

4.What problems need to be paid attention to in the service life of a cement house?

Although the service life of a cement house is very long, it is also necessary to pay attention to the following points:

External environment: natural environment, climate and temperature, rainfall, floods, etc. will affect the service life of cement houses, so it is necessary to prevent and prevent them.

Internal environment: Factors such as humidity, temperature, ventilation, and lighting inside the cement house will also affect the life of the cement house.

Renovation and reconstruction: In the process of renovation or renovation of cement houses, it is also necessary to pay attention to the impact on the building structure and not to destroy the structural stability of the house.

5.Summary. To sum up, cement houses have a long-term service life, but it is also necessary to pay attention to construction quality, material selection, maintenance and other issues to ensure the service life of the house.

1. The real use of cement was in 1756, but cement already existed in the Roman period.

2. The following is its development history;

In 1756, the English engineer JWhen studying the properties of certain limes to harden in water, Smiton found that to obtain hydraulic lime, limestone containing clay must be used for firing; The ideal composition of masonry mortar for underwater construction is hydraulic lime and volcanic ash.

This important discovery laid a theoretical foundation for the research and development of modern cement.

In 1796, the Englishman JParker fired a type of cement out of marl, which had a brown appearance, much like a mixture of lime and volcanic ash from ancient Roman times, and was named Roman cement. Because it is made of natural marl as raw material and fired directly without ingredients, it is also known as natural cement.

It has good hydraulic hardness and fast setting characteristics, and is especially suitable for projects in contact with water.

In 1813, the French civil engineer Picat discovered that cement made from a three-to-one mixture of lime and clay had the best performance.

In 1824, Joseph Aspdin, an English construction worker, invented cement and patented Portland cement. He used limestone and clay as raw materials, combined in a certain proportion, calcined the mature material in a vertical kiln similar to burnt lime, and then grinded it to make cement. It was named Portland Cement because its hardened color was similar to the stone used for construction in Portland, England Island.

It has excellent architectural performance and is of epoch-making significance in the history of cement.

In 1907, Bée in France used bauxite from aluminum ore instead of clay and mixed limestone to make cement. Because this cement contains a large amount of alumina, it is called "bauxite cement".

In 1871, the construction of a cement plant began in Japan.

In 1877, Crampton of England invented the rotary furnace, which was reformed into a better rotary furnace by Lansom in 1885.

In 1889, near the Kaiping Coal Mine in Tangshan, Hebei Province, China, a Tangshan "Fine Cotton" Plant was set up to produce with vertical kilns. In 1906, on the basis of the plant, Qixin Ash Company was established, with an annual output of 40,000 tons of cement.

In 1893, Hideyuki Endo and Misada Utsumi invented Portland cement, which was not afraid of seawater.

In the 20th century, while continuously improving the performance of Portland cement, people successfully developed a number of cements suitable for special construction projects, such as high-alumina cement, special cement, etc. There are more than 100 types of cement in the world, and the annual output of cement in 2007 was about 2 billion tons. In 1952, China formulated the first national unified standard, which determined that cement production should be based on the principle of multiple varieties and multiple labels, and renamed Portland cement according to the main mineral composition it contained, and later changed to Portland cement.

In 2012, China's cement output reached 100 million tons, accounting for more than 50% of the world's output.

Cement was invented and used because of the needs of engineering.
