Effects of Cement Characteristics on Concrete Properties ...

Discusses how different cement characteristics affect properties of fresh and hardened concrete. Cement characteristics include stone composition (main composition, Bogue calculation, alkalies, sulfates, minor components, loss on ignition, insoluble residue) and physical properties (fineness, particle size distribution, setting, compressive strength, heat of hydration, soundness).

Types of concrete - Wikipedia

High-strength concrete has a compressive strength greater than 40 MPa (5800 psi). In the UK, BS EN 206-1 defines High strength concrete as concrete with a compressive strength class higher than C50/60. High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower.

Aggregates - cement.org

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete.

Portland Cement - an overview | ScienceDirect Topics

3.10 Conclusion Portland cement is a complex product obtained from unprocessed common natural materials: limestone and clay. Consequently, the characteristics of Portland cement clinker may vary from one cement plant to another. To limit the variations of the technological properties of Portland cement,...

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements , such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (for its visual resemblance to …
