The tests included cements of five different finenesses, six different mixtures, and six different consistencies. Specimens were first stored in damp sand, followed by periods of air and water storage. The results of the tests are given in Table XXXV. Concrete of all mixes and consistencies showed expansion in damp sand and water storage and contraction in air. The change in length is practically independent of the fineness of cement and is influenced only slightly by Ratio of Water to Volume of Cement (JL. x) Fig. 31.--Water-ratio-Strength Relation for Cement K-3--Series 120.

The richer mixtures show somewhat less change in length than the...show more
