POSCO E&C said on the 24th it developed an "AI-based ready-mix concrete quality prediction and production automation technology" that produces uniform-quality ready-mix concrete.
Ready-mix concrete is affected by various factors such as the producer's skill, material properties, and temperature, so even if it meets legal standards, the industry has long cited the difficulty of consistently ensuring uniform quality.
POSCO E&C, together with SHLab Co., developed technology that uses AI analysis to check quality changes in real time and adjust automatically, solving this problem.
Artificial intelligence analyzes video of the concrete being mixed to determine the mix's consistency and automatically adjusts the mix ratio within KS standards. It also significantly reduced quality uncertainty by predicting compressive strength in advance through analysis of the mixing state and mix data—something that previously could be known only after waiting 28 days following placement. In addition, it automatically checks the amount of water remaining inside the mixer truck to prevent strength degradation.
Recognized for this technology, POSCO E&C won the top innovation award at the Ministry of Land, Infrastructure and Transport's "2025 Smart Construction Challenge."
A POSCO E&C official said, "Ready-mix concrete is a critical material that determines the safety of buildings, so we precisely manage every step from production to arrival on site," and added, "We will further advance our AI quality prediction technology to meet high quality standards."
With this technological development, POSCO E&C completed the establishment of a smart management system for the entire process of ready-mix concrete production–transport–receipt and inspection–construction–curing. It plans to build a technology cooperation system with public institutions such as LH and SH and major domestic construction companies, and to advance step by step into platform and service businesses that use AI-based quality control technology.
It will also work with the government to reflect digital verification methods for ready-mix concrete production information in the "Guidelines for Quality Control of Construction Works," and to request applying transport information management technology for ready-mix concrete to the "Construction Safety and Quality Management Information System (CSI)," strengthening the foundation for standardization and institutionalization.
