Workability of Concrete - Definition and Types - Civil Gyan

Workability is the property of concrete that determines the amount of useful internal work, necessary to produce full compaction i.e., it is the amount of energy needed to overcome friction while compacting concrete. Also defined as the relative ease with which concrete can be mixed, transported, molded, and compacted without any segregation.

What is meant by "Characteristic strength" (fck) of concrete??

Characteristic strength of concrete is one of the important properties of concrete which indeed unanimously by design engineer or any other person involved in the construction sector. The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck)- as per Indian Standards (ACI

Concrete Trial Mix Procedure | Concrete Trial Mix Design

The concrete trial mix design is prepared to analyze either the design mix would be implemented according to assumptions. When there is appreciable variation, accessible alternatives are :-Directly apply the trial mix ratios at the site. Rectify the trial mix ratios depending on the intuition and apply the modified ratios at the site.

What Is 1.54 In Concrete Calculation - DAILY CIVIL

The width of the concrete cube = 1 m. The height of the concrete cube = 1 m. Volume of concrete cube = length x Width x Height = 1 x 1 x 1 = 1 m³ (Wet volume) When we convert this wet volume into dry volume, the volume is increased by 54% of wet volume. ∴ Dry volume = Wet volume + 54% of Wet volume. = 1 + (54/100) x 1 =1 + 0.54 = 1.54.

Mix Design | Civil Engineering

Mix Design. Concrete mixes are designed with the aid of test records obtained from field experience with the materials to be used. When field test results are not available, other means of mix proportioning can be used as described in this article. In any case, the proportions of ingredients must be selected to produce, so that for any three

Segregation of Concrete - Causes, and Prevention

This type of segregation of concrete may occur if the concrete mix is too wet. i.e the addition of water in concrete dry-mix is higher than that is specified in the concrete design mix. Workability is a very important value of fresh concrete and water content of mix is a prominent factor that majorly affects the workability.
