POSCO E&C said on the 7th it developed "AI-based ready-mix concrete quality prediction and production automation technology" that produces ready-mix concrete with consistent quality.
Ready-mix concrete is affected by various factors, such as the producer's skill, material characteristics, and temperature, making it difficult to consistently secure uniform quality even if it meets legal standards.
To solve this, POSCO E&C developed technology with manufacturing AI specialist SHLab that uses AI analysis to check changes in ready-mix concrete quality in real time and automatically adjust it.
AI analyzes video of the concrete while mixing to determine the slump and automatically adjusts the mix ratio within KS standards. POSCO E&C said it also reduced quality uncertainty by predicting compressive strength in advance—previously known only after a 28-day wait following placement—through analysis of mixing conditions and mix data.
It also automatically checks the amount of water remaining inside the mixer truck to prevent strength degradation. This new technology won the top innovation award at the "2025 Smart Construction Challenge" by the Ministry of Land, Infrastructure and Transport on the 7th.
With this development, POSCO E&C completed the establishment of a smart management system covering the entire process from ready-mix production to transport, receipt and inspection, construction, and curing, and will build a technology cooperation framework with public institutions such as Korea Land & Housing Corporation (LH) and major domestic builders, while pursuing platform and service businesses that use AI-based quality management technology.
It will also work with the government to reflect digital verification methods for ready-mix production information in the "quality management guidelines for construction work," and plans to request the application of ready-mix transport information management technology to the "Comprehensive Safety and Quality Management Information System for Construction Work" (CSI).
