Abstract
In this project a study of Roller Compacted Concrete (RCC) has been done restricting the scope to laboratory tests. Since concrete also consists of solids, water and air like soil, the maximum dry density and the optimum moisture content are determined for the RCC in the laboratory. Based on this, casting of specimens is done by compacting with 4.89 kg rammer producing heavy compactive energy at optimum moisture content. Test results indicate that this concrete can be used for paving applications, because the flexural strength has been found to be more than 4.5 MPa. Hence, a comparison of RCC pavement with conventional pavement is needed to explore the advantages and to strongly recommend the same for pavements. Conventional concrete shows more flexural strength than RCC, but the difference in required thickness of pavement designed as per IRC 58:2011 is very small. Taking into consideration the men, materials and equipment usage, RCC pavement is found to be cheaper. If future study on the chemical behaviour of RCC is carried out, more solutions can be found for mass concreting problem.
