Now, the best of both worlds!
Not only did they successfully develop a new type of road filler, but they also found an extremely useful utilization angle for sodium chloride, which was about to become a burden problem.
In the end, Wu Tong finalized a new road construction plan, using special steel nanowires to weave a fixed skeleton grid with an appropriate distance, filling it with a special road filling material, hydrochloric acid-sodium chloride, and then brushing a layer of reinforcement coating on the top. The three compartments are connected to each other.
The highway subgrade based on this can not only be built in an integrated manner, but the construction period is expected to be shortened by four to five times. At the same time, the overall strength of the subgrade can be four to five times stronger than traditional reinforced concrete pouring!
The carrying capacity has naturally increased several times compared to traditional highways, and most importantly, the construction cost can be directly reduced to one-fifth of the original. Even if special design and various power supply facilities are taken into consideration, the total cost is less than half of the previous cost, which is very worth promoting.
In Wu Tong's deduction and prediction, the product that has been specially treated and fused, which can also be called sodium silicate, will have excellent properties that ordinary cement concrete does not have. It is repairable under ultra-high temperature.
Listing out the advantages one by one is enough to make this excellent road filling material stand out among ordinary concrete and asphalt, and become an emerging material of choice for road construction.
The material model has been finalized and the preparation process has been preliminarily set. Everything just needs to be tested on the finished product.
"Teacher, the derivation and design of the extended material course for a recycling project has been completed, and we can now start the experiment. Are you free to supervise the experiment?" Wu Tong first called Cheng Huanan. The recycling project naturally refers to the series of projects of Zhongyuan Group.
In Wu Tong's concept, this is a supplement to her regeneration project, not a separate topic.
"Of course, I'll go to the lab right away!" Cheng Huanan was naturally very interested in Wu Tong's new material verification and agreed immediately.
He has just finished the verification project of a new type of aluminum alloy material. This new type of aluminum alloy has a wide range of applications, especially in aerospace, rivets, aircraft propellers and high-strength parts on aircraft, as well as various structural parts and high-load parts...
He had just submitted this super aluminum alloy two days ago. These two days, he was putting the final touches on the project, repeatedly pondering and reviewing the scientific research process and materials. This was his way of learning to further deepen his mastery.
When he heard that Wu Tong had made new progress, he was extremely happy.
"Cheng Xu is here with me. Cheng Xu and I will contact Tao Ran and the others to arrange for laboratory preparations!"
With the personnel in place and the materials ready, the experiment began. Wu Tong's free R&D funds had already been allocated, so funding for the experiment was the least of his worries.
Wu Tong does not need to report anything in advance about such free experiments. Afterwards, when Wu Tong is willing or has time, he can add a simple experimental description so that the superiors can have a basic understanding of the use of this funding. There are no rigid regulations or requirements.
Wu Tong's deductive preparation process was perfected, and soon the experimental results, sodium silicate nanocrystals and special steel nanowires produced under a special process, appeared in front of everyone. There was undoubtedly a joyful atmosphere in the laboratory.
"Conduct the test!" Wu Tong looked at the materials that met her expectations and nodded slightly. They were the products of her deduction.
Precise tests were conducted on the instrument, and the data was compared horizontally and vertically, tabulated, as Ruan Chengxu kept records. He reported each step to Wu Tong: "Compared to concrete, the strength is 50% higher! It has all the advantages of asphalt concrete, but with an added bonus. Combined with MC-4 microfiber nanowires woven into a skeletal grid, the strength is increased by 4.7 times..."
As expected, Wu Tong's first move revealed its effectiveness. While the improvement in each material might seem minor, surpassing typical specialty cement, when all the components were combined, the performance and strength were dramatically improved.
"With the reinforcement coating, it can also be increased to over 5. According to the shock load data, it can withstand earthquakes below magnitude 10, as well as floods and waterlogging disasters!"
If such data were released, it would shock the world.
"Not bad, as expected!" Wu Tong was delighted when all the data came in. She could contribute to the agricultural assistance project. "Teacher, let's submit this to the higher-ups so they can conduct a large-scale experiment before rolling it out!"
After all, these are laboratory data, which still has certain limitations. Before promoting alternatives, Wu Tong still recommends that they conduct more precise experiments on a larger scale. After all, this is a matter of public welfare and cannot be ignored!
In the Research Department, Chu Hengyuan was pleasantly surprised when he saw the research report submitted by Wu Tong. "Thank you, Mr. Wu, for your support for the nation and the people's livelihood. I'll arrange for the data transfer right away!"
He first expressed his highest gratitude and excitement to Wu Tong over a confidential phone call, and then immediately contacted the security department to escort the information to a special factory.
Later, without any hesitation, he took the information to the National Academy to meet with the elders.
"Great, great, great! We're so lucky to have such researchers!" The elders exclaimed in delight. They knew all too well the benefits of building expressways connecting the country. However, China's vast territory and diverse terrain made infrastructure construction more challenging than one might imagine. However, despite all odds, they forged ahead with the construction of this nationwide expressway.
From gritting their teeth, overcoming numerous difficulties, and tightening their belts to build their first expressway, to now, they have built nearly 70,000 kilometers of expressway, the cost of which is almost immeasurable. Every kilometer was paved with real money, built by countless engineers and workers who gave their all and overcame countless difficulties.
People who don't understand might ask why building highways is necessary given the difficulty and high cost involved. Even some public intellectuals, spouting nonsense, ask why the money isn't distributed to alleviate poverty and ensure equal wealth for the people.
However, the country is gritting its teeth and building highways at all costs, not for show, but for deep and profound strategic significance.
Expressways can shorten driving time between cities and between cities and villages, improve transportation efficiency, promote logistics and the interconnection between urban and rural areas and large cities; they can improve traffic conditions, accelerate the flow of materials, and promote regional economic development; they can significantly reduce logistics costs and improve corporate competitiveness.
It can provide a convenient way of travel, facilitate people's travel, entertainment and tourism, enhance the city's image, and bring about the development of emerging industries, thereby increasing the city's comprehensive competitiveness...
