The king is rich and young: My apprentice has been pitted again!

Chapter 523 Sponge City
"Pervious concrete is also called porous concrete, sand-free concrete, and permeable floor. It is a porous lightweight concrete made by mixing aggregate, cement and water. It does not contain fine aggregate and is covered by coarse aggregate. A thin layer of cement paste is bonded to each other to form a honeycomb structure with evenly distributed pores, so it has the characteristics of air permeability, water permeability and light weight. The technology of ecological permeable concrete is constantly developing and updating, and the application range of permeable concrete is also expanding. It is used in urban roads, green tree pools, garden landscape roads, city squares, etc., and can also be made into colors to make the city more beautiful."

Lin Wu originally rejected this major, and never listened carefully in class. She just felt that she was hired by Lin Lanxue.

However, after entanglement and thinking last night, she discovered that the New World is just like.

Materials, energy and information are listed as the three pillars of modern civilization and life, and materials are the basis of energy and information.

The advent of a certain new material and its application will often cause major changes in human society.People thus divide human history into the Stone Age, Bronze Age and Iron Age.

Transitioning from one era to the next in the 21st century, the emergence and wide application of semiconductor silicon and highly integrated chips have pushed mankind from an industrial society to an information and knowledge economy society.

According to the classification of chemical composition, materials can be divided into metal materials, organic polymer materials, inorganic non-metal materials and composite materials.

Lin Wu's major in inorganic non-metals is closely related to all these.

"About permeable concrete, responding to the national call for 'sponge city', can you speak more simply?" Liu Zhengguang said suddenly.

"Sponge city, this is very good!" Lin Wu felt that whoever came up with this point, the founder is simply a genius, "Sponge city refers to the fact that the city can adapt to environmental changes and deal with natural disasters like a sponge. Water absorption, water storage, water seepage, and water purification. There will be no water accumulation on the road, no fear of wet shoes when walking, no flooding in the city, and no need to worry about flooding the house due to an imperfect drainage system, because the water on the road will seep down. "

Su Shaomian was reading the competition materials, but when he heard the girl's excitement, he couldn't help but raised his glasses and gave him an appreciative look.

This girl is the "Rotten Pesticide Girl", Mijuno's best friend, the one who often cheats when playing with pesticides?

Why does he feel different, like a different person.

"Student Lin Wu, the teacher was joking with you just now. You don't need to move the test blocks by hand. You only need to record the experimental data, and summarize on stage, and make PPT explanations. Can these be done?" Liu Zhengguang was worried at first, but came Girls can't work with their hands, and their brains are not as good as boys, so they just come to play.

Liu Zhengguang asked Lin Wu to talk about permeable concrete. She could explain it in a professional and complicated way, or in a simple and understandable way.

This, he appreciates very much.

"Yes. Then I have to do experiments with them, otherwise, theory and practice will be disconnected, right?" Lin Wu paid attention to applying what he learned, and not letting himself become a "high score and low energy".

"Theoretically, assistance can also help with light tasks, such as weighing water." Liu Zhengguang said.

Liu Zhengguang accepted the last team member and asked them to work in the laboratory.

On the way to lead Lin Wu to the laboratory, Ye Junlei leaned over to Lin Wu: "Hey, why are you here? You didn't come for me, did you?"

Just after opening the door of the laboratory, Ye Junlei was a little excited, and suddenly screamed!
