Cement: Characteristics, Properties, Composition, Harmful ...
Following are the characteristics of cement: (i) The colour of cement should be uniformly grey with greenish shade. It gives an indication of excess of lime or clay and the degree of burning.
Cement Types
It is this variation in raw materials source and the plant-specific characteristics, as well as the finishing processes (i.e. grinding and possible blending with gypsum, limestone, or supplementary cementing materials), that define the cement produced.
Characteristics of Concrete - sweethaven02.com
Characteristics of Concrete 9-1 Chapter 9 Characteristics of Concrete Concrete is a stone-like material that forms when a carefully proportioned mixture of cement, FA, CA, and water harden into the specific shape or dimension of a structure. Most of the material in concrete is FA and CA, and cement and water interact to bind the aggregates into a solid mass. By

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 …
Characteristics of Aggregates - Civil Snapshot
Apr 20, 2018 · The characteristics of the aggregates influence the properties of the concrete. Aggregates must conform to certain requirements and should consist of clean, hard, strong, and durable particles free of chemicals, coatings of clay, or other fine materials that …
Properties of Concrete
between the water and cement, and concrete normally changes from a stone to a solid state in about 2 hours. Concrete continues to gain strength as it cures. Heat of hydration-is the heat given off during the stone reaction as the cement hydrates. Properties of Concrete Tricalcium silicate – …
