Supplementary Cementitious Material

Metakaolin (MK) is a mineral admixture, various tests are carried out on the usage of Metakaolin for the development of high strength concrete. MK is a supplementary cementitious material derived from heat treatment of natural deposits of kaolin. Metakaolin exhibits high pozzolana reactivity due to their amorphous structure and high surface area. Concrete is the most commonly used material for development of infrastructure. As infrastructure is growing there arises problems in repairs. Due to manufacture of cement, Co2gets emitted into environment. Researches started on working partial replacement of cement, which occur naturallyor manufactured. The different type of pozzolonic materials like metakaolin, silica fume, and fly ash etc, are the material have binding properties that of cement. The present study focuses on replacement cement with metakaolin by 0, 5, 10,15and 20% and fine aggregate with M-sand by 50%.

Present Thesis

Concrete is a versatile material and can be extended to applications requiring to perform in aggressive environments. In these environments, concrete should be highly durable for longer service life. The present thesis is an effort directed towards the achieving high performance in concrete by using RHA as supplementary cementitious material. To achieve high Strength in the concrete, it is necessary to have better understanding of the behavior of constituent materials. Thus, the behavior of RHA in concrete in terms of efficiency was assessed through the results available from literature. A mix design method was suggested and a wide range of concretes varying from 85-87Mpa with replacement levels varying from 0 to 15 Percentage were attempted. These concretes could be produced with the mixing, compaction, curing procedures conventionally used and with the available RHA. A maximum strength of about 86Mpa was obtained which compares well or was even better with the results reported hitherto in literature.

Method Factors

High strength concrete (HSC) has large application because of good performance and high durability. Optimizing mix proportions has main effect on the compressive strength of HSC. In this paper, optimizing mix proportions are investigated by Taguchi method, factors of water to cementitious material ratio (W/C), fine aggregate to total aggregate ratio (FI/AG), silica fume as supplementary cementitious material and cementitious material content were selected at three levels. After testing L9 orthogonal array and analyzing results by Taguchi method, the best optimized mix levels were predicted by Taguchi. Then optimum mix was constructed and tested. It was concluded Taguchi forecast is true about optimized mix levels.
