wells it is hoped that the benefits of the API system of classification and specification will be realized and that the system will find wide acceptance and use by all who are concerned with the cementing of oil and gas wells, Portland cement is a hydraulic product made by 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. /Rect [430.864 502.634 501.936 520.12] /FT /Tx endobj /Rect [66.4424 539.999 110.439 557.485] /N 285 0 R /P 240 0 R /F 4
