analyzed to judge whether the cement has been correctly placed. Cement evaluation logs and other cased-hole logs can indicate the strength of the set cement and whether it "s bonded to the cas.ng (far right). The out- come of a cementing job, however, depends ultimately on choosing the appropriate cement and additives to cope with particuAmerican Concrete Institute Method of Mix Design (ACI–211.1) This method of proportioning was first published in 1944 by ACI committee 613. In 1954 the method was revised to include, among other modifications, the use of entrained air. In 1970, the method of mix design became the responsibility of ACI committee 211.

Slightly more than half of all low-rise buildings in the United States are constructed from concrete. Designers select concrete for one-, two-, and three-story stores, restaurants, schools, hospitals, commercial warehouses, terminals, and industrial buildings because of its ...
