In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the
To measure the Work Ability of Concrete by Compaction Factor test – Concrete Practical
Concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains
To measure Consistency of concrete by using Slump Cone – Concrete Practical
The importance of concrete in modern society cannot be overestimated. Look around you and you will find concrete structures everywhere such as buildings, roads, bridges, and dams. There is no escaping the impact concrete makes on your everyday life. So
To Determine Specific Gravity of Coarse Aggregate – Concrete Practical
Coarse aggregates are particles greater than 4.75mm, but generally range between 9.5mm to 37.5mm in diameter. They can either be from Primary, Secondary or Recycled sources. Primary, or ‘virgin’, aggregates are either Land- or Marine-Won. Gravel is a coarse marine-won
To Determine Aggregate Impact value of Aggregate – Concrete Practical
Aggregate is a granular material obtained by processing natural materials. BS882 splits aggregate into coarse and fine elements, coarse being described as gravel or crushed rock and fine being described as sand.Aggregate consists of particles of a rock, of a
To determine Strength of Concrete by using Flexure Test – Concrete Practical
Concrete is an ancient material of construction, first used during the Roman Empire. Concrete today is a sophisticated material to which exotic (foreign) constituents can be added and, with computer-controlled batching, can produce a product capable of achieving 50,000 psi compressive strength.
To Determine Sieve Analysis on Coarse Aggregate – Concrete Practical
Coarse aggregates are particles greater than 4.75mm, but generally range between 9.5mm to 37.5mm in diameter. They can either be from Primary, Secondary or Recycled sources. Primary, or ‘virgin’, aggregates are either Land- or Marine-Won.Secondary aggregates are materials which are
To find the Overall Efficiency of a Centrifugal Pump – Hydraulics Practical
Centrifugal pumps are used to induce flow or raise pressure of a liquid. Its working is simple. At the heart of the system lies impeller. It has a series of curved vanes fitted inside the shroud plates. The impeller is
To compare Actual and Theoretical force for stationary object of different shapes – Hydraulics Practical
At a very basic level, hydraulics is the liquid version of pneumatics. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties. In fluid power, hydraulics are used for the generation, control, and
To find Efficiency of a Reciprocating Pump-Hydraulics Practical
Reciprocating pump is a positive plunger pump. They are used widely in lifting water from ground to the storage tanks in residential areas. They develop high pressures but has limited use. Reciprocating pump consists of “suction stroke” and a “delivery
