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.

碾压混凝土路面试验研究

在本项目中，对碾压混凝土(RCC)进行了研究，但仅限于实验室试验。由于混凝土也像土壤一样由固体、水和空气组成，因此在实验室中确定了碾压混凝土的最大干密度和最佳含水率。在此基础上，在最佳含水率下，用4.89 kg的夯击器进行试样的压实，产生较大的压实能。试验结果表明，该混凝土抗弯强度可达4.5 MPa以上，可用于铺装。因此，需要将碾压混凝土路面与传统路面进行比较，以探索其优点，并强烈推荐相同的路面。常规混凝土比碾压混凝土表现出更高的抗弯强度，但按照IRC 58:2011设计的路面所需厚度的差异非常小。考虑到人员、材料和设备的使用，碾压混凝土路面的成本更低。如果今后对碾压混凝土的化学性能进行深入研究，将为解决大体积混凝土问题提供更多的解决方案。
