Application of Admixtures in Qingdao Building Component Factory

Qingdao Component Factory is a state-owned first-class building component factory and is one of the largest building component factories in Shandong Province. Our factory attaches great importance to technology and has tasted the sweetness of "technology is the primary productive force", achieving good technical, economic and social benefits. For example, the Qingdao Haier construction site urgently needs 860 12m long C40 concrete precast piles with a pile section of 450mm × 450mm; The user requires the component factory to deliver all the goods within 8 days and put them into use. The quality of the piles must be guaranteed and cannot be cracked. The strength must reach the design strength level standard value of 100. It can be said that time is tight, the task is heavy, and the quality requirements are high! What should I do? After discussion, the factory department unanimously agreed to adopt the Mu Hu brand MNC-A? Type early strength agent. On site actual sampling of specimens under the same curing conditions showed that the 1d strength reached 67% of the design strength grade standard value?? The 72? D strength has reached 75? Of the design strength grade standard value?? On the 5th day after pouring and forming, if the strength of 86? D is greater than the design strength grade standard value of 100, it will be transported directly to the construction site for pile driving construction. All piles have no cracks and have received high praise from users.
