burning and grinding a mixture of calcareous and argillaceous materials, such as limestone and clay, limestone and shale, limestone and marl, chalk, and clay, or limestone and iron blast furnace slag Although portland cement is primarily a construction product, it is usedextensively also in oil-well cementing operations, Test procedures and specifications for the performance of various types of portland cement in construction work ale maintained by the American Society for Testing Materials (ASTM) ASTM tests are made-quate for determining the performance of cements in wells because they are made under conditions dissimilar to those encountered in oil-well cementing operations The literature reveals that this fact has been recognized since the early use of portland cements in wells 1.
