Development of High Performance Concrete

Making of High Performance Concrete, which is chiefly used as a building material in the major and mega infrastructure and projects, is a very big task. Though the recent advancements have dominated the barriers of the preparation of high performance concrete, the use of green materials such as Meta-kaoline, Silica Fume, Fly Ash and Rice Husk Ash is limited. Apart from the green materials, numerous conventional and mineral admixtures are available in the current market, which enhances the quality and performance of the concrete such as Metakaoline, Alccofine and Silica Fume etc. The quality of concrete mixture is evaluated through various mechanical properties like compressive strength, flexural strength and split tensile strength and various durability tests like rapid chloride penetration test (RCPT), sorptivity test, chloride resistance test, accelerated corrosion test and sea water attack test are carried out to analys the performance of HPC. The prime objective of this research study is to evaluate the structural strength of high performance concrete by utilizing green and pozzolanic material as supplementary cementitious material. This research study primarily focuses on the development of empirical correlations for estimating the 7 days and 28 days compressive strength with sufficient workability diverse range of water/cement ratio for concrete mixes. Detailed laboratory investigations are performed covering almost all available supplementary cementitious materials like Meta-kaoline, Silica Fume, Fly Ash and Rice Husk Ash nearby area of Madhya Pradesh state of India. This Research study helps in identifying the influence of Meta-kaoline, Silica Fume, Fly Ash and Rice Husk Ash on the strength characteristics of HPC. The use of alternative material of Portland Cement leads to reduction of emission of harmful gases and impact on production capacity of cement manufacturing plant. This research work will enhance and accelerates the decision making process in the pre construction as well as post construction stages of any infrastructure projects. Further the above developed empirical model can be applied for all manufacturing of high performance concrete using supplementary cementitious material. These developed correlations can offer excellent engineering judgment and assist in decision making process for the structural evaluation of the HPC during pre-construction and post construction stages.
