THE INFLUENCE OF CEMENT COMPOSITION AND FINENESS ON CONCRETE SHRINKAGE, TENSILE CREEP AND CRACKING TENDENCY

Cement paste shrinkage data obtained by measurement of 76.2 x6.35 x 6.35 mm specimens, are used to establish statistical relationships between cement compositions and fineness and also concrete shrinkage. The importance of C3a and sulphate levels in the cement is discussed. Despite the lack of correlation between the shrinkage and strength properties of concrete made with particular cements, it is demonstrated that shrinkage, tensile creep and cracking tendency of concrete is strongly influenced by the individual cement used in its manufacture. Shrinkage and creep rates are similarly affected and the influence of these properties on measurement of ultimate shrinkage and micro-cracking is discussed. (A)./TRRL/
