- High-elasticity Concrete Technology
- Increasing the dynamic stiffness of concrete is essential for vibration control in high-specification semiconductor production equipment. Through material selection and mix design optimization, this technology manufactures high-elasticity concrete and precast concrete (PC) with an elastic modulus that is 30-60% higher compared to conventional concrete.

- Early Strength Concrete Technology
- A vital technology for 3-day cycle construction in mixed-use complexes, apartments, and buildings, early strength concrete provides 1.5-2.0 times faster early strength development compared to conventional concrete. This shortens formwork removal time by 40%, achieving a significant reduction in construction time.

-
- High-durability Concrete Technology
- By quantitatively assessing and pre-simulating factors that degrade concrete’s durability (such as salt damage, carbonation, and freeze-thaw cycling), this technology evaluates the durability of concrete structures exposed to special environments, predicts their service life, and secures the target service life through the manufacture of suitable concrete.
-
- Mass Concrete Heat of Hydration Control Technology
- This technology addresses temperature cracking in large cross-section mass concrete caused by the heat of hydration during cement curing. By comprehensively considering factors related to design (mix) and construction (curing), the technology derives and applies the optimal construction method for controlling temperature cracks.
-
- Exposed Concrete Technology
- This concrete manufacturing and construction technology allows for the use of concrete's inherent color and surface texture without applying additional finishing materials after formwork removal.
-
- Structural Diagnosis and Repair and Strengthening Technology
- Through construction state diagnosis (displacement measurement) and durability evaluation (cracks, corrosion, carbonation), this technology assesses and analyzes the soundness of structures, proposing optimal repair and strengthening solutions based on the findings.
