DMS 4600, "Hydraulic Cement" covers blended cements and allows Type IL cements to be approved. Item 421 Table 8 allows the use of Type IL cement in Class A, B, E, and P concrete. When Sulfate Resistant Concrete is specified, Type IL cements are not allowed. – This could change depending on ongoing research. 15
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 ...
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 …
