CREEP OF AIR-ENTRAINED CONCRETE
THE CREEP OF MIXES HAVING THE SAME WORKABILITY AND STRENGTH AT LOADING IS SHOWN NOT TO BE AFFECTED BY THE PRESENCE OR ABSENCE OF ENTRAINED AIR, SO THAT THE APPROXIMATE LINEAR RELATIONSHIP BETWEEN CREEP AND STRESS/STRENGTH RATIO PREVIOUSLY FOUND FOR PLAIN CONCRETE APPLIES ALSO TO AIR-ENTRAINED CONCRETE. A CORRELATION BETWEEN SPECIFIC CREEP AND THE MODULUS OF ELASTICITY AT LOADING IS SHOW TO EXIST FOR THE FULL RANGE OF CONCRETE, MORTAR AND NEAT CEMENT PASTE MIXES TESTED. AIR-ENTRAINED CONCRETE FITS THE SAME CURVE AS THAT OBTAINED FOR PLAIN MIXES OF THE SAME STRENGTH BECAUSE BOTH HAVE THE SAME TOTAL VOID CONTENT (AIR, CAPILLARY PORES AND GEL PORES). THIS VOID CONTENT IS OF FUNDAMENTAL IMPORTANCE IN UNDERSTANDING THE MECHANICAL PROPERTIES OF CONCRETE. /RRL(A)/
