2015-5-25  Because of this, the relation between pulse velocity and compressive strength cannot be expected to be independent of age and water/cement ratio. It appears, however, that, for compressive strengths up to about 4,000 lb/in 2, the relation may for practical purposes be regarded as being so. For concrete of the same aggregate)cement ratio, it was ...
