Kondraivendhan

Biography

B. Kondraivendhan worked extensively almost for 4 (2006 - 2010) years on pore size distribution of cement based materials exclusively on OPC and fly ash. ï‚· 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. ï‚· 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. ï‚· 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. ï‚· 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.
