U.S. Industrial Flooring Research Validates Abrasion Resistance of Type IL Cement

en.Wedoany.com Reported - On September 10, Amrize disclosed the results of an industrial flooring concrete study it participated in. The study was jointly supported by the ACI Foundation, the American Cement Association, and the Concrete Advancement Foundation, with the research conducted by a Temple University team. Amrize and Concrete Strategies participated in full-scale field trials, focusing on evaluating the abrasion resistance and carbonation performance of Type IL portland-limestone cement and its combinations with supplementary cementitious materials when used in industrial flooring.

The study included both laboratory tests and full-scale field trials, comparing the performance of traditional Type I/II portland cement, Type IL cement, and Type IL combined with supplementary cementitious materials. Abrasion testing was conducted in accordance with the BS 8204-2 standard. The study also examined the carbonation rates of different cementitious systems and the effects of early carbonation on the durability of the flooring surface layer. According to ACI Foundation project materials, the study also referenced test methods including ASTM C779-19, ASTM C944-19, and BS 8204-2.

Published results show that, under controlled mix design, placement, and surface finishing conditions, Type IL concrete can achieve abrasion resistance comparable to that of traditional Type I/II cement concrete. The study primarily targets large-area industrial flooring, including distribution centers, warehousing facilities, and data centers—buildings that must withstand long-term cyclic vehicle and equipment loads.

The field portion of the project was carried out jointly by Amrize and Concrete Strategies, using full-scale floor trials to validate laboratory test results. The ACI Foundation noted that industrial distribution facilities often have millions of square feet of concrete flooring and must withstand high-frequency traffic cycles. Therefore, the study focused not simply on comparing material strength, but on validating the wear performance and long-term application conditions of Type IL systems under actual flooring conditions.

Type IL cement reduces clinker usage by replacing a portion of clinker with limestone. According to research materials from the U.S. National Concrete Pavement Technology Center, Type IL systems typically reduce cement production energy consumption and carbon emissions through approximately 10% clinker replacement. However, different raw material sources, mix designs, and curing conditions can still affect strength, durability, and construction performance, which is why its industrial flooring applications had previously required more field data validation.

The results of this study were officially released in April of this year by the ACI Foundation, the American Cement Association, and the Concrete Advancement Foundation. The additional information disclosed by Amrize on September 10 mainly concerns the implementation of its participation with Concrete Strategies in the full-scale field trials, and further confirms the field validation results of Type IL systems in industrial flooring applications. The research team proposed that subsequent results can be used to support the improvement of performance-based specifications and related industry technical guidelines.
