| Abstract | Presently, ternary-blended concrete is widely accepted as a building material, which is obtained from two well-known materials. It can be used for enhancing the structural properties (mechanical and durability properties) of the concrete as well as increasing the total quantity of the replacement level of cement. It is also useful to eliminate the drawbacks of the particular supplementary cementitious materials through combining with other superior quality material and reducing the overall cost of the concrete production. In this paper, the mechanical and permeability properties of self-compacting concrete (SCC) containing metakaolin (MK), rice husk ash (RHA), and a combination of MK and RHA (1:1 ratio) were evaluated and their interrelationships discussed. For this purpose, different mixtures were prepared with different amounts of MK and RHA and ordinary Portland cement (OPC) was replaced by 5 to 40 % of MK and RHA. As a result of increasing the percentage of MK, RHA, and MK + RHA, the mechanical and permeability properties of SCC improved considerably. One interesting point is observed that the sample incorporating the ternary blend of cement with 15 % MK and 15 % RHA showed better workability and mechanical and permeability properties than that of the normal SCC sample without MK or RHA. This blend was proven to be the optimum combination for achieving maximum synergistic effect. In addition, the linear relationship between chloride penetration in terms of total charge passed and the (SiO$_{2}$ + Al$_{2}$O$_{3}$ + Fe$_{2}$O$_{3}$)/CaO ratio was studied. |

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.
