Sulfate resistance. Lower C 3 A contents in cement correspond to increased sulfate resistance. Therefore, Type II cement, which is intended for moderate sulfate resistance, is allowed a maximum C 3 A content of 8%. Similarly, Type V cement, which is intended for high sulfate resistance, is allowed a C 3 A content no greater than 5%.. Early-age strength development and increased heat of hydration

Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.

The most common included angles for drills are 118° and 135°. These angles are an artifact from the time when drilling was largely a manual process, and the drill bits were conventional conical shapes. Over time, tool makers learned that by grinding a conical point with a flat surface (a facet) to create a linear chisel, they could reduce the
