What is workability and durability of concrete?

What is workability and durability of concrete?

Workability of Concrete is a broad and subjective term describing how easily freshly mixed concrete can be mixed, placed, consolidated, and finished with minimal loss of homogeneity.

What does workability mean?

Workability is also defined as the amount of useful internal work necessary to produce full compaction of concrete. Workability is the property that determines the effort required to manipulate a freshly mixed quantity of concrete with minimum loss of homogeneity.

What is meant by durability of concrete?

Durability of concrete may be defined as the ability of concrete to resist weathering action, chemical attack, and abrasion while maintaining its desired engineering properties. For example, concrete exposed to tidal seawater will have different requirements than an indoor concrete floor.

What is durability in civil engineering?

Durability is defined as the capability of concrete to resist weathering action, chemical attack and abrasion while maintaining its desired engineering properties. It normally refers to the duration or life span of trouble-free performance.

What is workability and factors affecting workability?

Factors affecting the workability of concrete are materials such as water content, cement concrete, sand and aggregate properties such as size, shape, grading, mix design ratio and use of admixtures. Each and every process and materials involved in concrete mixing affects the workability of concrete.

What is low workability?

Concrete with a little amount of water is known as low workable concrete. Its water-cement ratio is below 0.4, and the compaction factor for this concrete is about 0.85. Low workable concrete has high aggregate segregation due to a lack of cement paste lubrication to stick with aggregates.

How many types of workability are there?

Workability of concrete can be divided into following three types: Unworkable Concrete. Medium Workable. Highly Workable Concrete.

How is workability measured?

The concrete slump test or slump cone test is the most common test for workability of freshly mixed concrete which can be performed either at the working site/field or in the laboratory. To maintain the workability and quality of fresh concrete, it is necessary to check batch by batch inspection of the concrete slump.

What is durability structure?

Durability is the resistance to degradation of products, materials, buildings and other built assets over time.

What is workability Quora?

Workability is defined as ease with which fresh concrete can be mix, transported, placed, compacted and finished to final shape with minimum efforts and without segregation of ingredients.
