Abstract:This paper sets forth the care taken in the inspection and testing of 7 million barrels of portland cement used in 4 million cu yd of concrete of great uniformity and every indication of durablity after 12 years of observation. It stresses for the concrete the importance of lower water solublity, freedom from "laitance," lack of cement burns of the workers, low alkali content, and it shows above all the necessity of manufacturing control of the cement clinker. It describes how premature set of concrete was prevented. It also deals with the inspection, grading, and testing of aggregates. The Board of Water Supply specificatons for aggregates are given as well as other factors used in securing good material.
