Abstract :

Concrete is a versatile material for the construction of various types of structures in civil engineering field. The quarry dust is the material which is obtained by breaking stones. This quarry dust can be utilized for making concrete since this can able to meet the demand of construction sector. The natural sand takes millions of years to form. Under these circumstances use of quarry dust becomes inevitable. This paper is summarizing the results of an experimental program to be undertaken to investigate the significances of quarry dust replaced concrete along with two types of inhibitors .Organic base (Amine) and inorganic base (Nitrite) have been known for protection of concrete structures but are not commercially indigenous to most developing economics due to manufacturing difficulties and are toxic to the environment. Hence the present paper is to study a novel, Eco-friendly and hydrophobic green plant extracts inhibitor. The fine aggregate in the concrete is to be replaced with quarry dust in the range of 25%, 50%, 75% and 100%. The Compressive strength, flexural strength, split tensile strength and bond strength are to be taken for all the ranges of replaced quarry dust and best is taken for further studies. 1% of diethanolamine and bambusa arundinacea inhibitors are to be added separately with quarry replaced concrete. Impressed voltage test is conducted for finding corrosion initiation of concrete. The results of the inhibitors studied showed that Bambusa arundinacea has superior compressive strength and the corrosion rate was the lowest compared to ethanolamine. Bambusa arundinacea may be considered a better substitute for amine- based corrosion inhibiting admixtures for durable concrete structures due to its hydrophobic effects and environmentally benign.
