The automatic grinding machine provides fast grinding of cylinder specimen ends to obtain plane and parallel surfaces. The machine has selectable advance grinding time functionality by user from 50 to 400 seconds. Optimum grinding time per end of all type specimens is 90 to 120 seconds.
Roller Compacted Concrete Pavement, is a type of non-reinforced concrete pavement placed with high density paving equipment and then compacted with vibratory rollers. While the finished product is essentially concrete pavement, the engineering and construction of this pavement is very different from conventional concrete pavement.
These mixers are typically used for the larger Roller Compacted Concrete projects. They are usually non-tilting and have mixing chambers with screw-type blades rotating in the middle of the drum. The mixing time is usually controlled by the slope of the drum, which is typically 15 degrees.

Concrete scarifiers can remove your unwanted concrete quickly and efficiently, pummeling up to a quarter-inch of concrete in one pass. Concrete grinders range from single-head to heavy-duty dual-head machines for smoothing surfaces and preparing concrete for coating.
Roller compacted concrete was first used in the 1930s and 1940s for construction of dams, while the first application in the field of roads was recorded in the 1970s. In the last ten years, roller compacted concrete has been primarily used for military purposes, industrial carts, in the construction of ports, but also in commercial
Work performed included clearing, grubbing, and grinding of 670 acres; design, construction, and maintenance of a 50-acre multi-staged surface and subsurface dewatering system for two 90-foot-deep nuclear island excavations, as well as construction of 70 acres of roller-compacted concrete pavements over soil-cement pavement base layer.
Roller-compacted concrete pavements for highways and streets: Roller-compact concrete (RCC) is a combination of dense-graded aggregates, portland cement, and water. This zero deceleration concrete mixture, when placed with an asphalt paver and compacted to excessive density, offers high power, sturdy pavement structure for highways and streets.
Jan 04, 2016· With its placement and quick-set advantages, the use of roller compacted concrete is gaining fresh energy among cons and road agencies. “RCC is a concrete pavement formed
