What is the formula of rammed earth wall?

According to experts from Qijia. Rammed earth originated in the Yin and Shang Dynasties and has a history of more than 5,000 years. Therefore, the manufacturing technology and methods of rammed earth walls have been very proficient for a long time, but with the development of industrial civilization, rammed earth walls have become less and less, especially in economically developed cities. So, what is the formula of rammed earth wall? What are the advantages of modern rammed earth walls? Let's have a brief look with Bian Xiao.

A, rammed earth wall formula

The concentration of glutinous rice slurry is controlled at about 1%-2%, the ratio of soil to ash is controlled at about 3: 1, and the concentration of alum is controlled at about 0. 1%. Because there are many defects in the traditional rammed earth wall formula, a proper amount of curing agent will be added to the modern rammed earth wall formula to improve the bearing and compressive capacity of the wall and make it stronger.

2. What are the advantages of modern rammed earth wall?

1, close to nature: although the rammed earth needs to be prepared in strict proportion to ensure the bearing capacity and compressive capacity of the building, the rammed earth wall does not need bricks and gravel in the construction process, so it feels natural as a whole and can be integrated with the surrounding environment.

2. Energy-saving: At present, most buildings may adopt brick-concrete structure, which is expensive, but it also needs to consume a lot of materials. The rammed earth wall is different, with low cost and can be recycled. Coupled with modern advanced technology, brick-concrete structure is unfamiliar in performance.

3. It's warm in winter and cool in summer: I don't know if you have ever lived in a former adobe house. It's warm in winter and cool in summer, which is very comfortable. This phenomenon is actually because rammed earth has the functions of heat insulation, heat conduction and heat storage, so it can isolate the outside hot air in winter and store the internal heat in winter.

4. Low cost: the raw materials used for rammed earth are easy to find and locally sourced. Moreover, the process is simple, which can effectively shorten the construction period, saving not only the cost of material transportation, but also the processing loss, which is very convenient.

Editor's summary: the above formula of rammed earth wall and the advantages of modern rammed earth wall are introduced here, hoping to help you. If you want to know more, please follow Qijia. com。
