CONCRETE TECHNOLOGY64 CPI %u2013 Concrete Plant International %u2013 5 | 2025 www.cpi-worldwide.comBy reducing the temperature of incoming aggregates from approximately 45%u00b0C to below 5%u00b0C, the Hydro-Spiral enables contractors to:%u2022 Achieve target concrete temperatures without or with minimal use of ice.%u2022 Eliminate the production slowdowns associated with ice dosing.%u2022 Improve batch consistency and slump control.%u2022 Reduce dependence on admixtures, resulting in significant cost savings.%u2022 Warm silted water coming from the aggregates cooler is directly recycled back through the dedicated dirty water chiller. This specialised chiller cools the silted water and at the same time keeping the fines in suspension for direct re-use back into the aggregates cooler without need for any intermediate filtration. This closed loop cycle efficiently manages the water without any wastage and maintains the fines percentages in the coarse aggregates meaning what goes in goes out with the only difference being a reduction in aggregate temperature.Environmental and operational benefitsBeyond operational efficiency, the Hydro-Spiral also offers a compelling environmental advantage. Compared to icebased cooling systems, the Hydro-Spiral uses 50%u201370% less energy, aligning directly with NEOM%u2019s sustainability goals and its broader commitment to green building practices. This energy-saving approach is particularly relevant in a project that aspires to lead globally in carbon-conscious construction.A scalable model for the futureColdRock, encouraged by the early success at The Line project, is actively pursuing discussions to promote wider adoption of its technology across other major developments. This momentum could mark a shift from traditional approaches to concrete cooling, both for current and future projects. nFURTHER INFORMATIONColdRock %u2013 Mechanical Equipment %u2013 L.L.C. %u2013 S.P.C.Plot No. 92 %u2013 Unit No. 15Abu Dhabi %u2013 Musaffah %u2013 M-11, UAET +971 50 1803103T +49 5704 3289988info@coldrock-llc.comwww.coldrock-llc.com80-ton insulated aggregates cold weighing silo, ReadyMix Abu Dhabi, Mena Port UAE.Fresh concrete production temperatures are achievable even when ambient temperature exceed 40+ degrees Celsius.
