Growing Demand for Efficient Curing Solutions

Infrastructure development, particularly in emerging markets like India and China, is driving the need for high-quality, durable, and cost-effective construction solutions. As concrete plays a pivotal role in these projects, the curing process becomes essential in determining the final strength and durability of concrete products. However, traditional curing methods are often energy-intensive, costly, and environmentally unfriendly. This is where Curetec's advanced curing technologies come into play, offering a more sustainable, efficient, and precise approach to curing concrete.

Curetec’s systems have been designed with a focus on reducing energy consumption while maintaining strict temperature control, ensuring the highest standards of concrete durability and quality. The company’s flagship technology, the CureSteam system, is powered by the innovative Low-Pressure Steam Generator (NDG). This system not only provides unparalleled energy savings, but also ensures precise temperature management, critical for producing high-quality concrete components.

Curetec’s Curing Technology in Major Infrastructure Projects

One of Curetec’s latest success stories comes from its collaboration with Shudao Investment Group Co., Ltd., a major player in China’s infrastructure sector. Shudao selected Curetec Shanghai as the primary supplier for its two large-scale infrastructure production facilities. These projects exemplify the critical role that Curetec’s curing systems play in delivering high-quality, durable concrete components while significantly reducing energy consumption.

The first project, located in Nanchong, Sichuan Province, is an automated facility for the production of turnout sleepers for China’s expanding high-speed railway network. The facility emphasizes automated production, efficiency, and the highest quality standards to meet the stringent requirements of the Chinese Railway authorities. A key challenge was the installation of 14 fully automated curing rooms, responsible for post-treating concrete to ensure maximum durability while supporting the facility’s productivity goals.

The meticulous curing regime implemented at this facility, involved a controlled heating phase where the concrete temperature is increased by ≤15º C per hour to a maximum of 50º C. This is followed by a four-hour hold at peak temperature, after which the temperature is decreased at a controlled rate of ≤15º C per hour, until it reaches within 10º C of the ambient temperature. Throughout the entire process, the temperature must not deviate by more than ±3º C from the set values, ensuring consistency and durability in the final product.

Curetec’s decision to implement the CureSteam system at this facility, featuring the NDG, was a game-changer. The NDG, with a capacity of up to 2400 kWh, is at the heart of the system, ensuring that only the required amount of energy is generated. This has resulted in energy savings of 50% or more, compared to conventional steam boilers. Additionally, ventilation and humidification systems were installed in all curing rooms to regulate temperature fluctuations caused by hydration heat, ensuring optimal curing conditions even in high external temperatures.

Following the success of this project, Shudao Investment Group opted to utilize Curetec’s curing technology in its second major facility in Chengdu. This new mega factory produces a variety of precast concrete components, including bridge elements, tunnel segments, support structures, track slabs, and pre-stressed heavy track sleepers for high-speed railways. Once again, Curetec’s advanced curing systems were able to meet the demanding temperature control tolerances without any issues, delivering both the energy efficiency and high productivity required for such a large-scale operation.

Focus on Innovation and Sustainability

What sets Curetec apart from its competitors is its relentless focus on research and development. The company is constantly innovating to improve the efficiency and effectiveness of its curing systems, ensuring that its clients are always ahead of the curve in terms of both technology and sustainability. Curetec’s systems are designed not only to reduce energy consumption but also to minimize waste and emissions, making them an environmentally friendly option for companies looking to reduce their carbon footprint.

The production speed and service delivery across the Asia-Pacific region are greatly enhanced by Curetec’s production and service center in Shanghai. This strategic location allows Curetec to provide faster turnaround times for its clients, ensuring that projects are completed on schedule without compromising on quality. In a region where infrastructure development is booming, this capability is a significant competitive advantage.
