The incentives for the Long-Time Study of Cement Performance in Concrete, announced by the Portland Cement Association in the News Letter,’ ACI Journal, January 1941, are found in a paragraph from that an-nouncement as follows: of It is of concern alike to the producer and consumer portland cement that the performance of concrete under the rigors of service cannot always be predicted or relied upon with certainty. These predictions are based upon premises which depend upon an attempted correlation of laboratory research and observation of field operations with field performance. Since the non-reliability of the predictions seems to be due to a lack of proper correlation between laboratory and field observations and field performance, the Portland Cement Association is about to undertake a long-time study of the performance of cement in concrete.
