Zhang Wen called him and said in an anxious tone: "Mr. Zeng, you must go to the resettlement room today. There are some things that need your decision."
This phone call made Zeng Yiming feel a little more uneasy. In the hot summer weather, the people and work on the construction site were very complicated. Since Zhang Wen called him, it meant that the things they encountered were something that Zhang Wen could not handle easily.
"Okay, I'll be there in a minute."
Lei Zhongxiang and Ma Qingchuan discovered during the inspection of the construction site that this batch of mortar was mixed with two thousandths of the cement content of Mortar King, which greatly improved the workability of the mortar and significantly increased the wall-building speed.
Now there is a fatal problem. The wall built yesterday can still be rubbed with sand today. He is worried that the strength will not meet the design requirements. He told Ma Qingchuan about this, and the two of them visited several houses in a row, but the result was the same.
They reported this matter to Luo Yuntong, who did not dare to make the decision in the face of the progress. He had not had time to conduct experiments during the construction period, but this batch of mortar test blocks was made. He did not know what the result was, so he reported the matter again. Gave it to Zhang Wen.
Zhang Wen's first thought was that the weather was extremely hot and the red bricks evaporated very quickly after being watered. The water content of the red bricks was not up to standard, causing rapid absorption of moisture in the mortar.
Luo Yuntong took him to visit the site and found that the workers were all veterans and naturally knew how to keep the bricks moist. They poured water carefully before laying the bricks.
"We don't want to be in such trouble. If the quality is unqualified due to these small things, Mr. He won't give us rework. In the end, we will be the ones who suffer." The workers complained to him.
They walked to the mixing station again, where there was a person in charge of the experiment. He couldn't help complaining: "The sand and cement are used in the same batch as other parts. The mud content of the sand meets the requirements, and the mix ratio and mixing time are also It’s the same, the only difference is that when using Mortar King additive for the first time, the dosage is also used according to the instructions. According to regulations, you should wait for the experimental results to come out before using it, but Luo Gong insisted on grabbing time.”
This sentence made Luo Yuntong's face turn red. He did not shirk his responsibility and spread his hands: "The construction schedule is so tight, there is no time at all."
Zhang Wen immediately made a decision and asked them to stop using Mortar King and replace it with hydrated lime powder.
There are currently five walls using Mortar King, all with a height of about two meters.
Lei Zhongxiang and Ma Qingchuan looked at each other, helplessness intertwined in their eyes. They jointly expressed their thoughts: "The temperature reached 35° during the construction yesterday. We also specially timed the time. The mortar was transported from It only took an hour.”
Another important reason why they pay attention to this situation is that brick-concrete structures rely on masonry walls to bear the load from the upper walls and structural panels.
He rushed to the scene. Zhang Wen summoned Luo Yuntong, the head of the engineering department, Lei Zhongxiang, the on-site foreman, Ma Qingchuan and others to the conference room for a secret meeting.
Zeng Yiming listened to their chatter for a long time, finally weighed the gains and losses, considered it, sighed, and ordered the others: "Now we need to find out how this batch of mortar kings flowed in, you guys come down Ask the material guy.
Let's stop the construction of these five buildings first and wait for the maintenance. If it still doesn't work, just tear them down and build them again. "
Du Guorui, the person in charge of the experiment, smiled. He thought that the district construction and building materials quality inspection center laboratory has a mortar penetration resistance meter. As long as the mortar in the test mold passes the penetration resistance test, the standard strength can be calculated.
JGJ/T136-2001 "Technical Regulations for Testing the Compressive Strength of Masonry Mortar by Penetration Method" gives a very detailed conversion method. Combined, the strength will reach more than 30% in three days, 50% in seven days, and 70% in fourteen days. The theory is that the design strength will be reached in 28 days.
Make a new batch of test blocks and send them for inspection three days later. You will naturally know whether they are qualified or not.
It's just that this will cause the five buildings to stop working for three days.
After he expressed his thoughts, he stopped talking and looked at Zhang Wen and Zeng Yiming.
"Let's do it this way. You can find a way to make up for the three-day construction period." The latter made the final decision and turned the matter over.
After he finished speaking, he glanced at everyone and warned loudly: "We are all old people in this industry. This industry is strictly prohibited. Don't take any chances. Forget it this time. Next time, I will definitely investigate the relevant people." Personnel Responsibility.”
After hearing this, Zhang Wen quickly came out to protect him: "Yes, let's forget it this time. Next time, I will definitely fine you heavily. I will fine you one year's salary and make you drink from the northwest wind."
Zeng Yiming thought that he said he wanted to drink, so he ran away for a few days and invested four million to buy a winery. This bastard had done something like this. He gritted his molars and added.
"Okay, okay, I will not hold you responsible for this matter. However, as the project manager, Mr. Zhang has management responsibilities, so this time I will deduct three months of his salary and give him A lesson to teach him to be more careful in the future!" Zhang Wen looked confused, he had to shoulder the blame for his feelings.
As soon as Zeng Yiming finished speaking, the atmosphere in the conference room suddenly became tense. Everyone lowered their heads and couldn't help but wonder what kind of impact this incident would have on them.
"Okay, now that the matter has been found out, let's not waste any more time." Zeng Yiming raised his hand to signal everyone to quiet down, "Now, what we have to do is to solve the problem as soon as possible and ensure the quality of the project. Du Guorui, you are responsible for organizing the personnel , make a new batch of test blocks and send them to the testing center for inspection."
Du Guorui stood up quickly and said, "Okay, Mr. Zeng."
Zeng Yiming continued: "Luo Yuntong, as the head of the engineering department, you have to bear the main responsibility for this incident. I hope you can learn from it and strictly control your work in the future to ensure that similar things will not happen again."
"Mr. Zeng, I..." Luo Yuntong looked pale and lowered his head guiltily.
"Okay, that's it for this time. Everyone should take this as a warning and must be serious and responsible in their work in the future to ensure the quality of the project." After Zeng Yiming finished speaking, he left the conference room.
Everyone dispersed, deeply reflecting on this incident. They understand that project quality is the bottom line that Zeng Yiming values, and they cannot take it lightly at any time. At the same time, they also realize that they must strictly abide by the procedures at work and cannot ignore quality just to rush for the construction deadline.
In the days that followed, everything on the construction site returned to normal. Luo Yuntong leads the staff of the engineering department to strictly control every link to ensure the quality of the project.
At the same time, they also accelerated the construction progress and tried to make up for the time wasted due to this incident.
Three days later, the test results came out. After the penetration resistance test, the strength of this batch of mortar met the design requirements. After hearing the news, everyone finally breathed a sigh of relief.
Zeng Yiming also deeply reflected on this incident. He realized that as the person in charge of the company, he still had many shortcomings in management. Therefore, he decided to strengthen supervision of project quality to ensure that every link was foolproof. It is imperative that the company establishes a quality safety department, which is directly under his jurisdiction and specifically inspects each construction site.
As for that batch of mortar kings, after investigation, it turned out that they were test products given by the manufacturer when the material clerk was purchasing them. After learning the news, Zeng Yiming gave a serious warning to the material clerk to ensure that similar things would not happen again in the future.
