| Abstract | The mechanism of granules' density variation is analyzed in concrete block vibration forming processing. The simulation of the vibrating process is done by the discrete element method analysis software - PFC2D. The change of porosity in the process of vibration of granule groups is studied and the change law is revealed. The effect of four aspects is also discussed, which are friction coefficient of granular, particle size, vibration frequency and amplitude. The porosity is positively related to friction coefficient of granular and negatively correlated to particle size. Quadric curve can be used to model the relationship between vibration amplitude and porosity. The fluctuation of change of porosity can be decreased by choosing higher vibration frequency. These research results possess a certain reference value to the design of vibration parameters and improve the quality of building block. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
