Roller Compacted concrete paving(RCC) got it's start in the seventies. When the logging industry switched to environmentally cleaner, land based log-sorting methods. The industry needed a strong pavement to stand up to massive loads and specialized equipment. Today's RCC owes much of it's versatility to economically competing with other paving

Comparison of Typical Mixture Proportions of RCC and Conventional Concrete. Roller-compacted concrete (RCC) pavements are a type of concrete pavement that do not include embedded steel or load transfer devices and typically is not jointed due to its method of placement. Load transfer is provided in an RCC pavement by way of enhanced aggregate interlock developed due to the compaction of the

Roller compacted geopolymer concrete was successfully developed using recycled concrete aggregates. •. Ambient temperature curing of 56d gained 80% of the maximum strength of 48-hr oven curing at 60 °C. •. Roller compacted geopolymer concrete showed higher mechanical properties than similar cement concrete. •.
