The standard types of portland cement are: For maintaining a level of consistency between cement-producing plants, standards are key. Three types of portland cement are used for several applications: Type I cement is the general purpose and most common type. Rapid hardening cement attains high strength in the early days; it is used … It is commonly used for general construction, especially when making precast, and precast – prestressed concrete that is not to be in contact with soils or groundwater. It is the … A. In addition to defining portland cement types, ASTM C150-20 details ingredients, chemical composition, physical properties, and sampling and testing methods. It is generally assumed unless another type is specified. Fly Ash: It is a waste product from coal fired power stations and Railway locomotives etc. This reduces the leaching of calcium hydroxide when used in hydraulic constructions. White cement: This is cement containing additives like chromium, vanadium, titanium and nickel.
