Manufacturing and Uses of Portland Cement

Cement can be defined as the bonding material having cohesive & adhesive properties which makes it capable to unite the different construction materials and form the compacted assembly. Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in

Process of Steel Manufacturing

The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore ► coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace. Natural

Factors Affecting Precipitation Formation

Following are the factors mainly responsible for the formation of precipitation....A lifting mechanism to produce cooling of the air. A mechanism to produce condensation of water vapors and formation of cloud droplets. A mechanism to produce growth of cloud droplets to size capable of falling to the ground against the lifting force of air. When air ascends from near the

The Geological Cycle of Rock formation

Geological cycle includes many processes acting simultaneously. The most important of these begin with molten magma from within the earth forming into rock, then continue with rocks being broken down into soil, and that soil being converted back into rock.

Uses & Design of Flow Equalization Tank

Flow equalization is method used to overcome the operational problems and flow rate variations to improve the performance of downstream processes and to reduce the size & cost of downstream treatment facilities. To prevent flow rate, temperature, and contaminant concentrations from varying widely, flow equalization is often used. Variations occur

Distributary Head Regulator - Definition, Working Mechanism

The distributary head regulator is constructed at the upstream end (i.e., the head) of a channel where it takes off from the main canal or a branch canal or a major dis-tributary. The distributary head regulator should

Methods & Techniques of Irrigation

The pressurized systems include sprinkler, trickle, and the array of similar systems in which water is conveyed to and distributed over the farmland through pressurized pipe networks. There are many individual system configurations identified by unique features (centre-pivot sprinkler systems). 2. Gravity Flow Irrigation Systems convey and distribute water at the field

Municipal Wastewater Treatment Systems

Collection of domestic wastewater is best achieved by a full sewerage water drain age system. Unfortunately this method is most expensive and there is relatively few communities in hot climate which afford it. A modern hygienic method of night soil collection is the only realistic alternative. Treatment is required principally to destroy pathogenic agents in sewage or night

Secondary Biological Wastewater Treatment Process

The main objective of secondary treatment: To remove most of the fine suspended and dissolved degradable organic matter that remains after primary treatment, so that the effluent may be rendered suitable for discharge. Conventional secondary treatment can reduce the BOD's

Activated Sludge Wastewater Treatment Process

Is defined as a ‘Suspension’ of microorganisms, both living and dead’ in a wastewater. The microorganisms are active by an input of air (oxygen) thus known as activated-sludge. Activate-sludge is that sludge which settle down in a secondary sedimentation tank after the sewage has been freely aerated and agitated for a certain time in an Aeration tank. It contains

Activated Sludge Process Design

The activated sludge form the underflow of the final setting tanks should be returned to the inlet of the aeration tanks at a rote sufficient to maintain the MLSS concentration at the design value. Excess activated sludge withdrawal system and subsequent treatment and disposal of waste sludge. Since the whole process takes place in a liquid medium the hydraulic

Engineering Hydrology Class Lectures and Notes

Engineering Hydrology Helps in the following ways: Hydrology is used to find out maximum probable flood at proposed sites e.g.. Dams. The variation of water production from catchments can be calculated and described by hydrology.

Working Mechanism and Components of GPS

Each of the 24 satellites emits signals to receivers that determine their location or range by computing the difference between the time that a signal is sent and the time it is received.

Lifetime Prediction of Steel Penstocks

Predicting the lifetime of materials and components in engineering environments is the subject of this discussion. The method of prediction proposed here is based on two approaches: namely, The Corrosion Based Design Approach (CBDA) The Locations for Analysis Matrix (LAM). These methodologies are described in detail in other references.

Methods of Transportation of Concrete

Transporting the concrete mix is defined as the transferring of concrete from the mixing plant to the construction site. The main objective in transporting concrete is to ensure that the water-cement ratio, slump or consistency, air content, and homogeneity are not modified from their intended states. Concrete produced from a mixer is required to be transported to the
