Discrete variable is a type of quantitative variable that only take a finite number of numerical values from the defined limits of the variable. It neglects all those values that are in decimal. Discrete variable is also known as categorical …
It is a characteristic that is either given in the form of value or quantity and that varies over the time is known as variable. Values are the mathematical numbers (i.e. 0,1,2,3,4,5,6,7,8 and 9) and these numbers may be 1-digit …
ASD (allowable strength design) is one of the oldest system that is being used for the design of steel, beams, columns, roof slab, trusses etc… In this method design remains within the allowable stress. Hence, in ASD a factor of safety applies …
To classify various types of steel depending upon their strength. Each steel that varies has assigned a specific grade. ASTM has been provided all the specification of these grades in detail. Most common steel grades are; ASTM 300 ASTM 400 …
For easy understanding the variations in data. After the collection and tabulation of data, it can be represented by a graph. Most common graphs are Bar graphs Pie graphs Line graphs Bar Graph Bar graph represents the relation between class interval/group …
When a large list of numerical data is given, then to reduce the numerical work a frequency table is constructed that arranges the same data in the same class or group and that class will be distinct to the data …
When fresh concrete is laid at the site then proper curing of concrete is required, because structures are exposed to the environment and in these conditions if there is no such an arrangement against the environment, then there are many …
Water amount is the most prominent factor that affects the workability of freshly laid concrete. Workability is essentially the measure of how easy fresh concrete flow in between the voids. If concrete workability is more than in the same manner …
With the passage of time after mixing ingredients of concrete with water, workability of concrete starts shrinking. This happens because of fluidity loss from the concrete. Fluidity is the amount of available water in concrete that is being utilized in …
Bleeding in concrete is the movement of water to the surface of the concrete after manipulation. Bleeding is more prominent on the surface of concrete, when water to cement ratio is higher and it occurs when ingredients of concrete are …
