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.
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
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
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
In a Pelton Turbine or Pelton Wheel water jets impact on the blades of the turbine making the wheel rotate, producing torque and power. Learn more about design, analysis, working principle and applications of Pelton Wheel Turbine.Hydraulic Turbines are being
Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Coarse Aggregate Those particles that are predominantly retained on the
Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement which hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as ciment
Coarse Aggregate is the aggregate most of which is retained on 4.75 mm IS sieve and contains only so much finer material as is permitted by specification. According to source, coarse aggregate may be described as: Uncrushed Gravel or Stone– it
