on August 20, after 35 hours of continuous struggle, China Construction Commercial Concrete Gedian Factory successfully completed the 3744 square C50P8 micro-expansion mass concrete pouring task of the Pan-Semiconductor Industrial Park Project in Gedian National Economic Development Zone, Ezhou City.
Gedian National Economic and Technological Development Zone Pan-Semiconductor Industrial Park Project is a key project in Hubei Province. The project aims to build a modern semiconductor display industrial cluster area integrating "R & D – pilot test – mass production – supporting" in central China, and jointly build an efficient and coordinated development pattern of "R & D in Optical Valley, manufacturing in Gedian" with Wuhan East Lake High-tech Zone (China Optical Valley). C50P8 micro-expansion mass concrete is used for the supply of the bottom plate of the
technology enabling intelligent matching war high temperature
. The risk of shrinkage cracking of micro-expansive concrete can be significantly reduced by adding expansive agent. Because of the special structure of the bottom plate, the grade is high, and the average thickness is more than 1.5 meters, it needs to be poured continuously at one time. During the construction period, the high temperature is close to 40 ° C. The project and Party A put forward strict requirements for the control of mold temperature and hydration heat.
Faced with the challenge, the technical team of Gedian Factory quickly set up a team to tackle the key problems, and finally determined the optimal mix proportion through many times of mix proportion design, hydration heat calculation and trial verification. In the production process, measures such as spraying aggregate in the silo to cool down and adding ice in the pool are taken to effectively control the temperature of concrete and ensure its working performance.
On-site coordination and efficient implementation of the contract, the
production department cooperated with logistics to survey the pump site and driving route, and scientifically dispatched 3 pump trucks and 20 mixer trucks to work together; In order to ensure the smooth progress of mass concrete pouring, the factory team organized various departments to study and judge the project needs in advance, formulated a special supply guarantee plan, and carefully deployed the key links from raw material reserve, on-site duty, quality control, vehicle dispatch to logistics services. During the
pouring period, the factory team took overall command on site, the service team was on duty 24 hours a day, paid close attention to the construction progress in real time, strictly controlled the working performance of concrete, efficiently coordinated transport vehicles, dynamically optimized vehicle routes, and ensured the continuous and stable supply of concrete, which was unanimously affirmed by all parties.
