Japan: High school students develop convenient and lightweight concrete flower beds

< P > < FONT face = Verdana > Recently, four third-year students at Gifu Gakuen High School in Japan have developed a small green concrete technology that can be transported and built anywhere. And use this new type of green concrete to decorate the empty cement floor in the campus.

< P > < FONT face = Verdana > There are many holes inside the green concrete, which can be directly planted with plants. It is mostly used in the greening around rivers and so on. The simple green concrete invented by these students can be made into mobile courtyards.

< P > < FONT face = Verdana > The dimensions of this concrete are: 50 * 40 cm and 10 cm high. Among them, 5 centimeters deep is the planting part of the plant. Considering the water absorption of plant roots and other issues, repeated use of a variety of materials for testing, in addition, considering the miniaturization of flower beds must pay attention to its strength.

< P > < FONT face = Verdana > "The idea was well received by both teachers and students, and the professor of engineering at Gifu University said it was a very interesting study." Teachers in colleges and universities said. As one of the inventors, Ming and Wei himself also said: "I am very happy in the production process.". It can not only facilitate transportation, but also be traded as commodities.
