Research

During Ph.D., worked extensively almost for 4 (2006 - 2010) years on the pore size distribution of cement based materials exclusively on OPC and fly ash.

The focus of the work is to study the pore size distribution parameters such as mean distribution radius (r0.5), porosity and dispersion coefficient (d). The relationship between these pore size distribution parameters with mix factors such as w/c ratio, curing age and mean cement particle diameter and fly ash replacement are also studied.

Degree of hydration relationships as a function of w/b ratio, curing age are developed separately for OPC paste and fly ash-cement paste through the non-evaporable water content determinations.

A semi empirical relationship is developed for mean distribution radius as a function of w/c ratio, age and mean cement particle size for OPC and fly ash pastes and mortars.

The role of the proposed relationships for pore size distribution parameters of OPC and fly ash pastes and mortars on compressive strength, permeability and hydraulic diffusivity is also demonstrated.

The microstructure studies on concrete and pozzolana blended concrete were carried out as part of the Post Doctoral research during Dec 2010 to July 2012.

Strength and durability studies on ultra- high performance concrete were also done in the Post Doctoral research during Dec 2010 to July 2012.

Research on Ferrocement confinement for short concrete columns was carried out.

Research on corrosion behavior of RCC is being carried out.

Research on ambiently cured Geo-polymer concrete research was carried out at SVNIT Surat.

Research on fabrication of bio-stone  with the help of bacteria are carried out at SVNIT Surat.

Research on utilization of natural fibres in concrete are also being carried out at SVNIT Surat.
