Introduction to roller compacted concrete: Roller compacted concrete is a mixture of cement with or without supplementary cementing materials, aggregates and water. Water content is low than freshly mixed, this concrete looks like damp gravel and it is a zero slump concrete. For bonding between two layers, segregation must be prevented.
Roller-compacted concrete, or RCC, takes its name from the construction method used to build it. It's placed with conventional or high-density asphalt paving equipment,then compacted with rollers. Roller-compacted concrete has the same basic ingredient as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone.

Roller-compacted concrete (RCC) pavements use the same materials as conventional concrete. The essential coarse and fine aggregates, cementitious materials (cement, fly ash, ground granulated blast furnace slag, etc.), and water are all used, but they are used in different proportions compared to mixes for conventional concrete pavements.As with any concrete mix, the selection of materials is ...
The weight of this roller can be increased by ballasting with concrete blocks. Typical weights vary between 5.5 tonnes net and 15 tonnes ballasted. Grid rollers provide high contact pressure but little kneading action and are suitable for compacting most coarse grained soils.
Sinoma Tianjin Cement Industry Design and Research Institute (TCDRI) has signed the equipment supply contract for the technical modification of a raw material roller press with Lianyuan Conch and three other cement production enterprises of the Conch Group in July 2021. The projects are located in Anhui and Hunan provinces of China.
The compressive strength of Roller Compacted Concrete is comparable to that of conventional concrete, typically ranging from 4,000 to 6,000 psi. Some projects have reached compressive strengths higher than 7,000 psi; however, practical construction and cost considerations would likely specify increased thickness rather than strengths of this ...

Loesche Mills for Cement Raw Material. 1934 Loesche mills are increasingly also used worldwide for limestone and cement raw material. 1937 400 Loesche mills have already been sold for coal, phosphate and cement raw material. 1939 The largest Loesche mill at this time is an LM 16 with two steel spring-loaded rollers, a grinding track diameter of 1,600 mm and product throughput of 22 t/h.
The basic types of hydraulic cement, blended cements or a combination of hydraulic cement and a pozzolan can be used in the Roller Compacted Concrete mix. Like conventional concrete, materials used in Roller Compacted Concrete mixtures should be selected for chemical resistance to sulfate attack, potential alkali reactivity, and resistance to ...
After the concrete is poured, a release agent often colored if not directly mixed into the concrete) is shaken and/or troweled on. The stamps are laid and tamped down to create an impression. Chisels and rollers may be used to clean grout lines between stamps and to finish edges where the stamping mats cannot reach. Finally a sealer is applied.
