RCC by Cemex
Cemex UK has launched a new non-slump concrete aimed at the surfacing market. The RCC has been designed as an alternative solution to asphalt, primarily for roads and surfacing. The cost of bitumen in the past two years has gone up by 60 per cent. Thus the company decided to find an alternative materials that would not only lower costs but also provide same strength and performance and surfacing.
RCC is based on a cementitious alternative to bitumen, containing the latest additives and technology. Although it offers the same characteristics as traditional pavement quality concrete, it is laid with conventional asphalt paving equipment.
Once laid, transverse cracks are induced at regular intervals to allow for any potential contraction of concrete. RCC's long-term life cycle cost benefits mean that it can be used for both new construction and maintenance of surfacing.
It could potentially be used on roads and highways with a thin asphalt overlay to ensure skid resistance and reduce noise.
