How closely can we determine the water-cement ratio of hardened concrete?
Abstract Generally, a determination of the water-cement ratio (w/c) of hardened concrete is not very useful, but there exist indirect methods for that purpose. A direct method, utilizing optical fluorescence microscopy, has been standardized by a Nordic organization; it requires the use of reference standards of a range of mixes with specific ingredients and a known curing history. The method is useful for quality control in repetitive production of concrete elements. A recent paper claims that the w/c of unknown concrete can be determined with a precision of ±0.02. A review of that paper, utilizing simple statistical tests, shows that the claim is unfounded, so that caution in the use of optical fluorescence microscopy is required.
