Concrete cooling and heating for Argentine dam

Concrete cooling and heating for Argentine hydropower project enables year-round mass concrete production

In Patagonia, Argentina, great potential has been identified for hydroelectric power generation as a renewable source of electricity. A major challenge to build the necessary dam structure with high quality mass concrete is the warm summers and cold winters. Therefore, we have provided our customer with a year-round concrete production solution that guarantees a fresh concrete temperature of 10 °C / 50 °F to meet the required quality standards.

Massive components and extreme temperatures

After we delivered our solutions for the production of mass concrete in winter to our customer in Patagonia in the extreme south of Argentina at the beginning of 2020, the delivery of a solution for concrete cooling followed towards the end of the year. The construction of a hydropower plant there requires the highest demands on the temperature of the mass concrete, as extreme ambient temperatures prevail and the durability of the concrete must be ensured.

Not for the first time, we were able to convince the customer with our competence and the wide product range of concrete heating and cooling equipment. From a single source, we supplied and commissioned our equipment for year-round concrete production. In order to avoid thermal stress, cracking and unwanted shrinkage, a rule of thumb states that the fresh concrete temperature to be achieved should be equal to the annual average ambient temperature. In this project, the fresh concrete temperature was defined as 10 °C / 50 °F, while the ambient temperature reached 30 °C / 86 °F in summer and was below 10 °C / 50 °F in winter. The total daily production capacity was set at 3,000 m³ of concrete per day.

365 days of temperature-controlled concrete production with KTI's CombiMaster CM50 in Austria

We equipped the concrete batching plant of an Austrian ready-mix concrete company with our CombiMaster to produce high-quality concrete all year round. The limited space at our customer's site was no problem for our very compact design, as the CombiMaster brings a complete cooling and heating system in just one 40-foot container. In addition, we supplied the customer with specially designed air nozzles that were installed in the existing silos.

Compact installation makes it possible

In 2021, we successfully installed another CombiMaster CM 50 at a customer in Austria. The requirement was to achieve a fresh concrete temperature from the mixer of 27-21 ° C / 81-70 ° F at an ambient temperature of 30-35 ° C / 86-95 ° F in summer. While in winter 15 ° C / 59 ° F concrete at -10 ° C / 14 ° F ambient temperature is the target.

Both temperature requirements are to be achieved with a production capacity of 300-600 m³ / 390-785 yd³ of concrete per day. Specially designed and manufactured air nozzles were supplied by us to the customer and installed in the silo chambers to ensure perfect distribution of hot or cold air through the aggregates and sand. Furthermore, our service technicians installed the air ducts and water pipes. The commissioning of the plant was done in two steps. First for the cooling side before the summer season. Secondly, the heating system was commissioned to make the plant ready for winter concrete production.
