Performance-Based Hydraulic Cement

ASTM C1157/C1157M is a performance specification for hydraulic cement. It classifies cement by required test performance rather than restricting the composition to one prescriptive recipe. The active edition listed by ASTM is C1157/C1157M-25. Project documents

7 Common Cement Types in Concrete Production

TeamCivil Concrete, Materials

Common Cement Types in the Concrete Industry Common cement types: In concrete production, there are multiple kinds of cement that can be used. The suitable type depends on the exposure conditions, required early strength, heat

Fineness of Cement

TeamCivil Concrete, Materials

The fineness of cement is a measure of how finely the manufacturer grinds the cement. For example, engineers commonly report it either as specific surface area in square metres per kilogram (m2/kg) or as the

Cement is a dry powder, usually grey in colour, prepared mainly from limestone and clay. Cement is a binder material. When water is added to cement, it hydrates and hardens. Mixing cement with water gives

Portland Cement

TeamCivil Concrete, Materials

Concrete is the most widely used man-made material today, with portland cement being the most common type of binder used in its production. Cement-based materials gain their strength and other properties through hydration, which includes

In a previous post about cement and its components, we mentioned that there are four compounds of cement. They are: Silicates Alite, C3S Belite, C2S Aluminates Tricalcium aluminate, C3A Calcium alumino ferrite, C4AF Portland Cement Hydration

ASTM: Types of Portland Cement

TeamCivil Concrete, Materials

ASTM C150/C150M-24 covers portland cement. Its active scope lists Type I, IA, II, IIA, III, IIIA, and V; combined designations such as Type I/II may be supplied when the cement meets both sets of requirements.

Introduction to Concrete Components

TeamCivil Concrete, Materials

The main components of concrete are cementitious materials, water, fine aggregate, and coarse aggregate. Many mixtures also contain chemical admixtures and intentionally entrained air. Fibers, pigments, or other materials may be added when the project
