Quality materials
The project made use of high-quality materials in the construction of this stretch. As Pai shares:
Cement was blended with fly ash and GGBS for the mix design of concrete; this was not only cost-effective but improved the durability of structures.
Micro-silica as mineral admixture was used in concrete, which helped achieve high-grade concrete strength.
VMA (viscosity-modified admixture) was used in self-compacting concrete for controlled cohesiveness and homogeneity of the concrete mix.
A curing compound was used that benefitted the time cycle, resulting in acceptable compressive strength.
Highly fluid epoxy grout (EP-10, Make-Fosroc) and non-shrink grout GP-2 were used for repairing.
Polypropylene fibre was used in concrete for precast structures (segments), which prevented shrinkage of cracks and increased bonding strength.
Inhibitor solution was used to prevent TMT bars from corrosion.
Bipolar admixture was used in concrete for corrosion prevention of TMT bars and had a positive impact on time, cost and manpower.
Solvent-free epoxy resin grout was used for anchor plate grouting.
PCE (polycarboxylate)-based admixture was used in concrete for designing workable parameters.
Omega seal expansion joint was used with high-quality neoprene, which benefitted in terms of the time factor and manpower for easy installation.
