Study of bond strength between various grade of Ordinary Portland Cement (OPC) and Portland PozzolaneCement (PPC) mixes and different diameter of TMT bars by using pullout test

A D POFALE, S P WANJARI

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 1,   Pages 39-45 doi: 10.1007/s11709-013-0193-y

Abstract: Since last two decades, the Portland Pozzolane Cement (PPC) is extensively used in structural concreteBut, till to date, a few literature is available on bond strength of concrete using PPC mixes.There are many literatures available on bond strength of concrete mixes using Ordinary Portland CementIn the present investigation, total 24 samples consisting of M20, M35 and M50 grades of concrete andWhereas, marginal improvement was noticed in maximum bond strength of PPC mixes.

Strategic Study of CAE 2002, Volume 4, Issue 1,   Pages 41-46

Abstract:

According to the cases of deterioration of big concrete structures investigated in Canada, it wasIn the respect of cement classification it was suggested to cancel “ordinary silicate cement”.The cement industry should be gradually changed to “green industry of cementitious materials&The standards and compositions of cement should be reviewed on the basis of technical advances of concreteFinally it was suggested to bring the production, circulation and utilization of cement into line in
