A. Yes. The ASTM Standard Specification for Portland Cement (ASTM C150) provides for five types as follows Type I—The standard product that has long been in use with no limitation on the proportions of the major oxides (CaO SiO 2 Al 2 O 3 Fe 2 O 3 ) also referred to as "ordinary portland cement.". Type II—This cement possesses
portland cement binding material in the form of a finely ground powder usually gray that is manufactured by burning and grinding a mixture of limestone and clay or limestone and shale. The inventor Joseph Aspdin of England patented the basic process in 1824 naming it for the resemblance of the cement when set to portland stone a limestone from the Isle of Portland.
(1) Cement. Portland cement shall conform to Item 524 "Hydraulic Cement". Unless otherwise shown on the plans or in the specifications the cement shall be either Type I IP II or III portland cement except as follows a. Type III cement shall not be used when the anticipated air temperature for the succeeding 12 hours will exceed 60 F. b.
Cementtreated base (CTB) is a general term that applies to an intimate mixture of native soils and/or manufactured aggregates with measured amounts of portland cement and water that hardens after compaction and curing to form a strong durable frost resistant paving material.

Cement type 5 is obtained from the ordinary cement and the 3 7 and 28 days of resistance offered by this type of cement is less than those of other Portland cement types thus it requires greater resistance and is limited in application. It should be applied with care in cold weather. Properties of cement type V
