The fresh properties were assessed using slump flow, v-funnel, l-box and j-ring test methods the basic requirements for flowability and resistance to segregation for self compacting according to european federation of national associations representing producers and applicators of specialist building products for concrete (efnarc) were satisfied. This free engineering essay on cement and concrete is perfect for engineering students to use as an example durability and fresh properties of mortar/concrete. Concrete workability is a broad and subjective term describing how easily freshly mixed concrete can be mixed, placed, consolidated and finished with minimal loss of homogeneity workability is a property that directly impacts strength, quality, appearance, and even the cost of labor for placement and finishing operations. Workability is a property of freshly mixed concrete concrete is a mixture of cement, aggregates, water, and admixturesthe properties of concrete, whether in the fresh state or hardened state, are affected by its ingredients and their proportions.

The amount of water in concrete controls many fresh and hardened properties in concrete including workability, compressive strengths, permeability and watertightness, durability and weathering. Workability is the ability of a fresh (plastic) concrete mix to fill the form/mold properly with the desired work (vibration) and without reducing the concrete's quality workability depends on water content, aggregate (shape and size distribution), cementitious content and age (level of hydration ) and can be modified by adding chemical.
