Roller Compacted Concrete

Roller concrete has been adopted from dam-building technology, where it is used as a rapidly constructed and durable solid concrete. In road construction, roller compacted concrete is predominantly used in foundations, as a supporting layer. For surfacing or as a layer of surfacing. Some applications in Belgium are discussed. This...

Although roller compacted concrete (RCC) made with and without fly ash (FA) has enjoyed numerous application of dams, roads and large floors construction in Europe, Japan, Australia and Unites States since 1970s, it has not almost yet been used at all in Turkey despite abundant and economical sources of FA...

This paper presents a concise mix design process using a geotechnical approach to produce RCC mixtures for mass and structural applications. Laboratory compaction tests, using a Kango hammer, were performed on specimens with a predetermined combination of aggregates and cernentious materials, varying the amount of water. 1 he test results...

An iiiteiisive iesearch on roller compacted concrete pavement for high speed roads has been conducted in China since the beginning of this decade. Many technical reports document that the surface of RCCP is smooth due to the effect of the roller, and texturing such dry and less workable material is...

At the Research, Development and Consulting Department of the Heidelberger Zement AG, a research project has been carried out on the influence of the composition and compaction on the properties of roller-compacted concrete. At a low compaction rate of only 96% of the modified proctor density, roller compacted concrete containing...

This paper presents the partial results of a research on Rolled Compacted Concrete (RCC) which aimed at characterizing its fatigue behavior. The influence of cement content (120, 200 and 280 kg/rn 3 ), the mixture aggregate grading (fine, medium and coarse) and the compaction energy (normal Proctor, intermediary and modified)...

In the case of roller-compacted concrete pavements (RCCP) in spacious site like yard, harbor and so on, socalled fresh joint technique at longitudinal joints is widely used in order to achieve high load-transfer efficiency. However traditional fresh joint technique allowed the limited length of placing, because delay between the fresh...

Usage of recycled concrete aggregates produced from crushed demolished concrete has been limited due to its higher cost and the difficulty caused from its major ingredients, cement mortar, and by-product powder. However, the exhaustion of aggregate resources and increase demand of preserving the natural environment require developing an effective application...

The scope of this work is the behaviour under abrasion of different concrete (RCC) made with limestone, schist and granite aggregates. Binder contents (cement and fly ash) ranging from 90 kg/rn 3 to 190 kg/rn3 were tested. Small concrete slabs 60x60x40 mm were cut from 150000 mm cylinders prepared according...

The ROLLFIBER process consists of roller-compacted cement concrete reinforced with steel fibers. It enables you to build continuous pavements without any joints. To reach this level of performance, the fiber has to have what is known as total' anchorage, and its action is optimized by the use of a concrete...

In the quest for introducing materials and techniques of construction, the Research & Development Division of the Road Development Authority, Sri Lanka has carried out several trials and successfully constructed an airport apron, a causeway of 2km length using Roller Compacted Concrete (RCC) pavements and a road of length 0.265km....

The research on RCCP was launched in early 80' in China. The laboratory test started in 1981 followed by the first sectioii of field experimcnt road in 1982. And then extended resmrch was carried out in 1983 and 1984. A few years later in 1988, the research on Cement Concrete...
