"Absolutely, sir, what do you want? We have a complete range of varieties here, essence cream, foundation, cream, lotion, shampoo, lipstick, are of guaranteed quality and inexpensive, especially the effect is internationally recognized, and has won the ......"

Xiao Wang's eyes were full of excitement, and he kept selling products to Li Ruoyu. Pen %Fun %Pavilion www.biquge.info she finally met a customer, and she had the urge to sell her money!

Li Ruoyu listened to the stiff smile on his face, sister, don't say anything about the price is not expensive, there is no product below 100 in the counter, that is, the lipstick that is not as big as his little finger is more than 100, which makes Li Ruoyu really feel unbearable. You don't have to give it away, do you?

However, there is only one way in front of him now, and that is to buy only the expensive ones, not the right ones. Dabao SOD honey is good, only two or three yuan a bottle, but take this to send the girl, expecting people to be happy to give it to the embrace, isn't that a dream?

"Then choose the gift package, come to ten copies, the price is preferential, I will come in the future, I am helping the company to procure, you just need to help me save some money, whether it is Women's Day, Children's Day, Spring Festival, Mid-Autumn Festival, I will come to you to purchase at a fixed point."

"Really, great! I'll give you the lowest price sir. Li Ruoyu's shameless mouth was full of, and Xiao Wang's heart was full of joy immediately, and he wanted to kiss him from the bottom of his heart.

Ten gift packages, that is, more than 2,700, after the discount, she also has more than 500 commissions, this money is enough for her to go to the pedestrian street clothing store to consume, looking at the soft sister coin that Li Ruoyu took out, the shopping guide Xiao Wang's eyes that have always wanted to go to South Korea for plastic surgery to make it bigger have strangely evolved into big cat's eyes.

Fortunately, Li Ruoyu didn't know about these. Otherwise, he would definitely hide his face and cry, and then say, "Sister paper, can this be returned?" ”

After paying the money, looking at the handbag on the ground, Li Ruoyu was worried that he couldn't get it back, and Xiao Wang had already taken the initiative to say that he would close down and help him send it over. Such a big customer, not to mention helping this little favor, even if she eats, drinks and plays, she also agreed.

"Sir, leave a phone number, I can call you if there are new products or activities in the future."

"Uh, okay."

Li Ruoyu looked at the other party's smile and understood that the other party had taken a fancy to his money. Although Xiao Wang is also a Peugeot, he has not yet reached the level of being able to seduce Li Ruoyu's unspoken rules, and after thinking about it, he gave the other party a phone call that he didn't have.

Twenty minutes later, when Liu Lei was about to disband and let the beauties go back to rest.

Li Ruoyu had already led Xiao Wang and arrived with a gift bag, so a group of girls were shocked for a moment, and they couldn't understand what Li Ruoyu was doing? Bribery? Cheap things can't make up for the girl's wounded heart.

"Xiao Wang, I forgot again, how much is this gift package? What's in it? ”

"Sir, what a noble person is so forgetful, this gift package is 300 yuan, which contains serum, eye cream, and moisturizing lotion...... All of them are the latest products of our international brand Meiya, which are guaranteed to have the best effect, and you can't put it down after using it once. Xiao Wang once again introduced it in a professional tone.

Li Ruoyu nodded frequently, and after seeing her leave, she looked at the girls on the scene, all of them had bright eyes, staring at the gift bag on the lawn, just like a hungry wolf seeing ribs and a pervert seeing a naked girl.

A gift package of 300 yuan, which not every girl can afford.

And it's a good brand, this brand has been publicized on campus, and some samples have been distributed, and the effect is still good.

"I bought some cosmetics for everyone, this is my compensation for everyone, a little heart, please smile, how many people are here today, can I count enough? One two three...... Ah! I'm really embarrassed to have bought one less. ”

Li Ruoyu said sincerely, and played a cautious eye.

"We don't accept apologies, and we can't send gold bars."

Liu Lei glanced at her and said, and the rest of the sisters also turned their heads in response when they saw this.

seemed to be unmoved at all, and suddenly Li Ruoyu was a little speechless, but one of the sisters panicked, it was not enough to score, and it was estimated that the fart would not be able to be fished if she was reserved, so the fat girl was the first to take a step forward and take one, "Brother Li, then I'm welcome, I haven't used such a good thing." The beautiful face was already crimson.

"Ahh I want it too! With an arrow step, Liu Lei rushed over.

Li Ruoyu endures more than handsome, in this era of increasing cheekiness year by year, pretending to be reserved is a very disadvantaged thing.

In the end, Li Ruoyu still did not escape, he was pulled by Liu Lei and gave a lecture to the students majoring in building materials, Li Ruoyu had no choice, fortunately, it was not difficult for him to take a little future theory, it was enough to shock these younger students.

So in the class that Liu Lei was in charge of, Li Ruoyu started his first class at his alma mater.

"Good afternoon, students! Today, I, a senior, am an axe in the class, and I am ugly in front of our teacher Liu Lei, and I will discuss and share with you some of the things I have refined in my actual work. Today I will first talk about concrete admixture! Hope it helps! ”

After speaking, Li Ruoyu smiled at Liu Lei under the podium, Liu Lei took the lead in applauding, and the classroom applauded continuously!

Li Ruoyu pressed his hands weakly and said with a smile: "Students, the most important thing in our university is actually the learning methods and ideas. Take our concrete as an example, the use of admixtures is a new idea, which is relative to the past. At present, the concrete admixture can be divided into two kinds of active materials and non-active materials according to its active size, and the so-called active materials refer to the substances that can be hydrated with the activator to form hydraulic cementitious products when there is water at room temperature and pressure, and the non-active materials can only improve the workability of concrete. But the two can not be separated, under certain conditions can be converted into each other, for example, limestone powder is generally not used as an active material, but if the cement clinker mineral tricalcium aluminate is more, it can be combined with the hydration product of tricalcium aluminate to form hydrated calcium aluminate is beneficial to the early strength of concrete, quartz powder is generally not used as an active material, but the activity can be greatly increased when the curing temperature of concrete components is high, of course, the quartz powder particles will also have a certain activity when the particles are fine enough, According to the hydration mechanism, the active materials can be divided into two categories: volcanic ash activity and potential hydraulic activity. For example, fly ash, tuff, burnt clay, etc. are volcanic ash active materials, which need to be activated before hydration reaction can occur; Steel slag, water quenching slag, etc. are potentially hydraulic-hard active materials, that is, they have a certain hydration ability. ”

"Therefore, it is customary to call the active material added in the production of cement as a mixture, and the active material added in the concrete mixing process as a concrete admixture. Let's talk about the mechanism of action of concrete admixture. Concrete admixture is to improve the strength, durability, workability and volume stability of concrete by improving the composition, quantity, and particle gradation of cement cementitious materials, which is mainly obtained with the help of several physical and chemical effects. The first is the active effect. (To be continued.) )
