-----Written after “  beautiful without cutting, concrete meets rammed earth“< /p>

Wittgenstein once said: Don't look for meaning, look for practice. Increasingly modern cities are constantly eroding human history and memory. The traditional meaning is being oppressed by the city and is constantly shrinking to the point of dying out.

In this camp where traditions are constantly shrinking, the traditions that can retain the original flavor are rapidly decreasing. Traditions improved by absorbing traditional elements and cultural genes are tenaciously continuing the meaning of tradition and retaining the essence of tradition.

Color TamperImprovement is the most direct means of inheritance and continuation. It is said that most people would not agree with the most advanced means, but it can survive and retain the blood before it dies. And how is it not the ultimate goal.

Ramped earth, following the longest architectural form of human beings. Perhaps it is the architectural form that has existed since the construction of dry columns. The buildings that have basically disappeared in modern cities are basically used in rural areas because they cannot afford to buy better building materials such as masonry and concrete. The form of the building. Because of beauty, because of love, because of local materials, because of energy saving and environmental protection, because of being able to return to the soil and be revived in the end.

 “Uncut but beautiful, concrete meets rammed earth”. It may be the first time that China has re-distributed rammed earth, the most basic building material that has been almost forgotten by architects, in the architectural world for the first time after restarting large-scale urban and rural comprehensive construction in the past two decades. The most extensive article on morphology. In just a few days, there were more than 200,000 readings and tens of thousands of reposts. What really shocked everyone was the connotation of "rammed earth": easy to obtain materials, low cost, in line with modern energy conservation and environmental protection, and the final building rammed earth "return to earth" after the demise of the building. idea. Or is it about rammed earth, which is the architectural form of earth in the minds of all Chinese people, after modern design can express the astonishing natural beauty, unmodified, symbiotic beauty in the earliest period of human beings?

Wang Shu, the only architect in China to win the Pritzker Prize, as the dean of the School of Architecture at the China Academy of Art, he is on the grounds of the China Academy of Art A "Waterfront Mountain Residence" built with rammed earth was built. The school is satisfied with the effect of rammed earth on the appearance, but there is a question of whether the rammed earth can be directly used on the interior walls of the hotel rooms In fact, the school has always held a skeptical attitude from the beginning of the design to the construction of the rammed earth. On the one hand, there is concern that the rammed earth wall is rough and sandy, which is unsightly and unsanitary; Although the French CRATerr  soil construction method, which is the most modern technology recognized worldwide, has been adopted in the construction of "Waterside Mountain Residence", and the experiment has proved the technological advancement of the experimental wall, but the school It is still difficult to rule out the rejection of the rammed earth wall, and finally used the method of applying transparent surface paste on the rammed earth wall for surface treatment. In the end, the school accepted the exposed soil walls in the house (quoted from: Zhang Wen's native). Here I have to think this way: what the school of the China Academy of Art needs is the natural beauty of rammed earth, the beauty of color and the sense of layering of rammed earth. The worry is that the hotel will eventually be a commercial building, and the guest's concept of the old earth wall and the lack of the earth wall itself will have a negative impact on the operation of the hotel. Therefore, a compromise was made by applying a permeable layer indoors.

The worry of the school is basically the worry of every owner who wants to use rammed earth to build!

Actually, modern rammed earth basically has two different technical schools. The ecological raw soil construction method of pure raw soil and ramming technology represented by the authoritative French CRATeer  soil research center and the raw soil improvement construction method of adding lime and cement concrete to the raw soil represented by Australia .

The advantages and disadvantages of the two different rammed earth buildings are very obvious: the CRATeer school using pure raw soil realizes the most ecological soil return Soil ecology concept. At the highest point of ecological environmental protection, it summarizes the rammed earth construction technology of human beings for thousands of years, and forms a systematic modern rammed earth construction method. It adopts a scientific method to end the ancient technology of rammed earth and uses modern technology to improve the formwork. Cultivated specialized talents of earth architecture (post-graduate students of earth architecture). It is difficult for modern large-scale urban buildings to realize industrialized production by the soil-based construction of systematic science. The acquisition of standard raw soil and the high cost of raw earth construction (several times higher than the cost of concrete) and because of the ratio of wall height to wall width and load bearing of rammed earth walls, rammed earth walls are only used in modern buildings function as a partition wall. The main body of the building still needs to be finished with a concrete structure.

The Australian way of adding lime, cement and concrete to raw soil. It basically deviates from the concept of the last belonging of the raw soil of ecological architecture: soil to soil. But for the wider use of the natural beauty of rammed earth, the beauty of color and the layered beauty of rammed earth are more convenient. Concrete rammed earth can more directly learn from mature concrete pouring technology and formwork technology, and operate on a larger scale. Due to the use of concrete technology, the surface of the wall can be decorated very smooth and carefully, and there will be no problems such as sand and mud on the surface. While gaining the beauty of rammed earth, the public avoids the shortcomings of earth walls. This is consistent with Wittgenstein once said: don't look for meaning, look for practice.

Is this what the author of "Beautiful Without Cutting, Concrete Meets Rammed Earth" wants to express?
