Water Cement Ratio - A Fresh Relook

摘要

The paper attempts to present a panoramic view of the water cement ratio strength relations adopted by a few national bodies and look at the appropriateness of them while keeping in mind the enormous number of variables that could influence them. These relations are also compared with a couple of databases reported to assess the efficacy of each of these in ensuring a reasonable prediction capability. This in a way will pave the way for an effective use of the cement in concrete leading to significant optimization of the concrete composite.
