Tang Dynasty detective

Chapter 166 Discussing Countermeasures
In the previous life, concrete filled every corner of the world, but in ancient times, it was a rare object.

Li Canghai is not a student of architecture. He does not know the formula of concrete, but he still has some understanding of the structure of concrete.

The so-called 'concrete' is nothing but a mixture of water, stone, soil, etc. The most important thing is the 'water-cement ratio', which is the ratio between the mixtures.

He dug more than ten shallow pits in order to conduct experiments at the same time in order to save time.

After all, the Yellow River flooded as it said, and he didn't have more time to study the concrete formula carefully.

An hour passed quickly, more than ten shallow pits, nearly half of the mixture hardened, but the strength was far from enough.

Li Canghai showed joy, which showed that his idea was feasible. Although the concrete lacked cement, the setting effect was obvious.

He readjusted the ratio according to the previous calculation. This time, his confidence increased greatly, and he selected several feasible ratios, and then observed carefully.

Until night fell, Li Canghai finally found the right proportion.

He let out a long breath and laughed out loud.

Chang Feng and the others were stunned by his sudden laughter, and surrounded him one after another.

"My lord... are you alright?" Chang Feng asked suspiciously.

"I found the formula, hahaha!" Li Canghai danced excitedly.

Several people looked at each other in blank dismay, Xiao Wu thought that he was suffering from epilepsy, and hurriedly reached out to feel for his pulse, wanting to diagnose him.

"My lord, what formula did you find?" Zuo Hongji asked in surprise.

Only then did Li Canghai realize that he had lost his composure, coughed a few times, and said excitedly: "The formula for plugging the gap! Chang Feng, where did you get this clay?"

Bending down to grab a handful of clay from the shallow pit in front of him, Li Canghai turned around and asked Chang Feng.

During the experiment, he found that besides the configuration ratio, there is one more important thing, that is soil.

The degree of hardening of the concrete made of different soils is not the same.

The pile of soil in front of him is very different from other soils. This pile of soil contains sedimentary rock.

Li Canghai did not know that this sedimentary rock belongs to marl, a kind of natural cement with good hydraulic hardness and fast setting characteristics, which is most suitable for projects in contact with water.

He himself didn't know the formula of concrete, but he discovered the key by accident. With this marl, he had the confidence to block the breach.

"My lord, the surrounding area is flooded. This is soil dug from the mountain." Chang Feng replied honestly.

"Chang Feng, from now on, take as many people as possible to dig out this kind of soil. In addition, smash all the stones." Li Canghai ordered.

Chang Feng didn't dare to neglect, and immediately took orders to leave.

Li Canghai pondered for a while, then he took out the official talisman and said, "Xiao Wu, you take my official talisman and drop all the people in the county government here to help, and in addition, you go to collect as many big ships as possible, Remember, it must be a big boat."

Although Xiao Wu didn't know what he meant, he didn't hesitate at all, took the official talisman and left in a hurry.

"My lord, the grass people don't understand, what does this have to do with plugging the leak?" Zuo Hongji asked with a puzzled expression.

Li Canghai smiled slightly and said, "You will know when the time comes. By the way, do you know where there is a lot of lime?"

"Caomin knows a businessman, and he has a lot of lime. If you want to use it, Caomin can talk to him." Zuo Hongji said.

"Since that's the case, it's hard work for you to make a trip." Li Canghai patted his shoulder and said.

"What did your lord say? The grass people know that everything you do is to stop the breach of the Yellow River. It is really a blessing for the grass people to work for you." Zuo Hongji bowed deeply to him, with a solemn expression. road.

Li Canghai nodded in satisfaction. He took out a half-finger-long brocade box from his arms, handed it to him, and said deeply: "Knowing mistakes can be corrected, and there is nothing good about it. I don't hate businessmen, and businessmen can promote The region is prosperous, and this official even encourages the common people to do business. However, this official does not like unscrupulous businessmen who make money with no conscience."

Zuo Hongji took the brocade box hesitantly, and when he opened it, he was stunned.

What is in full bloom in the brocade box is exactly the 'Snail Jade' that he gave to Li Canghai earlier!
"My lord... this." Zuo Hongji looked at him in astonishment, and said in doubt.

Li Canghai smiled calmly and said, "This thing belongs to you, but now it's just returned to the original owner. I'm not the kind of corrupt official who has an eye for money. If I accept this thing from you, wouldn't it be suspected of taking bribes?" Huayu is the treasure of the world, whether you buy it or keep it, it all depends on you."

Zuo Hongji immediately knelt down with tears in his eyes, and kowtowed to him a few times, Zuo Hongji said gratefully with red eyes: "My lord, you are the reborn parents of Caomin, please be respected by Caomin. "

Zuo Hongji never dreamed that Li Canghai would actually give him the 'snail jade'.

Since last night, he had dissipated all his family wealth, and all his servants and concubines left him one after another. On weekdays, those drinking and meat friends avoided him like a plague god, making him lament the cruelty of the world.

Now, Li Canghai gave him a chance, how could he not be excited?
Li Canghai helped him up, and said seriously: "With your ability, it is not impossible to make a comeback. I still say the same thing, people, don't be swayed by the desire for profit."

Zuo Hongji wiped his tears and said solemnly: "Don't worry, my lord. After this incident, the grass people have taken money very lightly. The grass people must remember the adults' teachings and be a conscientious businessman."

Li Canghai nodded slightly, and said in a deep voice, "Right now we need to work together to control the floods. You go early and come back early, and bring the lime here as soon as possible."

Zuo Hongji put the brocade box close to his body, bowed respectfully to Li Canghai, and left the Dragon King Temple in a hurry.

At this time, night fell.

Around the Dragon King Temple, many coolies gathered.

Most of these coolies were from Wang Buquan's forces. After being wiped out by Li Canghai, they were all dragged here for emergency rescue. The other part were people from nearby villages.

The flood happened for seven or eight days, and no one cared about it, but since last night, hundreds of people suddenly came, saying that they were ordered by the new county magistrate to come to rescue the emergency.

There were still some people nearby who hadn't fled, so they came to help one after another.

After all, this is where their ancestors lived.

Numerous torches were lit around the Dragon King Temple, and the red fire light was reflected on the water surface in front of the Dragon King Temple, forming a staggered up and down fire scene.

The sound of jingling and knocking on stones came one after another, and everyone was busy in full swing.
