Abstract:

The use of waterproofing chemicals in the field of concrete technology has proven a significant boom in the civil engineering industry by increasing the life of concrete structures. The materials such as nano-acrylic polymers resulted, significant control over the water leakage and damping conditions especially Terrasil and Zycobond and various nano sealers such as Zycoprime+ and Zycosil+. In this study, the primary focus is to waterproof tunnels using the various acrylic, nano-technological, and soil modifier chemicals to stabilize the tunnel structure in areas of hilly terrain. The use of these chemicals has been sourced in other areas of application but the least glance is seen in the field of tunnel engineering. These chemicals bind with the concrete and form a hydrophobic layer thus decreasing the permeability of concrete structure. In the present study the percentage of Zycobond and Terrasil used was 1.5% by weight of concrete and the ratio for Zs+:Zp+:water was 1:2:20. Tunnels especially in hilly terrain pass the flowing streams, thus making it more prone to damping conditions. So, poor site conditions result in less durability of concrete as well as steel, therefore improvement in engineering properties using these chemicals is primarily sought out in this paper. The factors considered during the use were the permeability, strength, volumetric analysis of chemicals, material properties etc. Water-proofing the concrete improves various engineering properties such as permeability, compressive strength, durability, strength, and various other properties of Concrete. The study emphasized to gauge the viability of Zycosil+ and Zycoprime+, Terrasil and Zycobond as waterproofing agents in concrete.
