Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special
Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. The partial substitution of fly ash for Portland Cement is an important aspect of RCC dam construction because the heat generated by fly ash hydration is significantly less than the heat generated by Portland Cement hydration. This in turn reduces the thermal loads on the dam and reduces the potential for thermal cracking to occur. RCC is a mix of cement/fly ash, water, sand, aggregate and common additives, but contains much less water. The produced mix is drier and essentially has no slump. RCC is placed in a manner similar to paving; the material is delivered by dump trucks or conveyors, spread by small bulldozers or specially modified asphalt pavers, and then compacted by vibratory rollers.

A wooden roller coaster is a type of roller coaster
Type of roller coaster
A wooden roller coaster is a type of roller coaster classified by its wooden track, which consists of running rails made of flat steel strips mounted on laminated wood. The support structure is also typically made of wood, but may also be made of steel lattice or truss, which has no bearing on a wooden coaster's classification. The type of wood often selected in the construction of wooden coasters worldwide is southern yellow pine, which grows abundantly in the southern United States, due to its density and adherence to different forms of pressure treatment.
