How to Construct Bridge

Different Methods of Bridge Construction
Described below are the different methods employed in the construction of bridges.

Cast-in-situ Method of Bridge Construction
This method is a flexible method of bridge construction where complex and unusual geometrical shapes of dams can be constructed easily. Situations when it is hard to transport pre-fabricated elements either due to size or unreachability, this method is a good choice.

the application of venturi meter in civil engineering?

It is widely used in large diameter pipes such as found in the waste treatment process. It allows solid particles flow through it because of their gradually sloping smooth design; so they are suitable for measurement of dirty fluid. It also be used to measure fluid more detail..

what is the flexural strength of concrete?

Flexural strength is one measure of the tensile strength of concrete. It is a measure of an unreinforced concrete beam or slab to resist failure in bending. It is measured by loading 6 x 6 inch (150 x 150-mm) concrete beams with a span length at least three times the depth.
Flexural test evaluates the tensile strength of concrete indirectly. It tests the ability of unreinforced concrete beam or slab to withstand failure in bending. The results of flexural test on concrete expressed as a modulus of rupture which denotes as (MR) in MPa or psi. The flexural test on concrete can be conducted using either three point load test (ASTM C78) or center point load test (ASTM C293). The configuration of each test is shown in Figure-2 and Figure-3, respectively. Test method described in this article is according to ASTM C78. more detail..

How to write feasibility report of project?

A Feasibility Study Report (FSR) is a formally documented output of feasibility study that summarizes results of the analysis and evaluations conducted to review the proposed solution and investigate project alternatives for the purpose of identifying if the project is really feasible, cost-effective and profitable. It describes and supports the most feasible solution applicable to the project. The report gives a brief description of the project and some background information. Formally this document is the starting point for running the Pre-Charter Sub-Phase. In practice, it signifies that the sponsor can proceed with deciding on project investment and make necessary assignments to the project manager. more detail..

How to calculate for cement volume?

dry volume of mortar=0.108 ,1.35=0.1458m3
Cement= (1/7) = 0.0208 m3
Density of Cement is 1440/m3 = 0 1440 = 29.99 kg
We know each bag of cement is 50 kg
= (29.99/50) = 0.599 Bags more detail..

CALCULATION FOR SAND QUANTITY (in 1 cubic meter concrete)?

CALCULATION FOR SAND QUANTITY Consider volume of concrete = 1m3
Dry Volume of Concrete = 1 x 1.54 = 1.54 m3
Sand= (1.5/5.5) x 1.54 = 0.42 m3 ∴ 1.5 is a part of Sand, 5.5 is sum of ratio
Density of Sand is 1450/m3
For KG = 0.42 x 1450 = 609 kg
As we know that 1m3 = 35.31 CFT
For Calculation in Cubic Feet = 0.42 x 35.31 = 14.83 Cubic Feet more detail..

CALCULATION FOR AGGREGATE QUANTITY (in 1 cubic meter concrete)?

Consider volume of concrete = 1m3
Dry Volume of Concrete = 1 x 1.54 = 1.54 m3
Aggregate = (3/5.5) x 1.54 = 0.84 m3 ∴ 3 is a part of cement, 5.5 is sum of ratio
Density of Aggregate is 1500/m3
Calculation for KG = 0.84 x 1500 = 1260 kg
As we know that 1 m3 = 35.31 CFT
Calculation for CFT = 0.84 x 35.31 = 29.66 Cubic Feet

How to calculate cement, sand quantity in mortar for plaster?

Area of brick wall for plaster = 3m x 3m =9m2
Plaster Thickness = 12mm (Outer-20mm, Inner 12mm)
Volume of mortar = 9m2 0.012m = 0.108m3
Ratio for Plaster Taken is = 1 : 6
Sum of ratio is = 7
Calculation for Cement Volume
Dry Volume of Mortar = 0.108 1.35 = 0.1458 m3
Cement= (1/7) = 0.0208 m3
Density of Cement is 1440/m3 = 0 1440 = 29.99 kg
We know each bag of cement is 50 kg = (29.99/50) = 0.599 Bags
Calculation for Sand
Volume Sand = (6/7) x 0.1458 = 0.124m3
Density of Sand is 1450/m3 = 0 1450 = 181.2 kg
Now we find how many CFT (Cubic feet) Required
As we know that 1m3 = 35.31 CFT = 0.124*35.31
= 4.37 CFT (Cubic Feet) more detail..

Boring Techniques for soil exploration?

Boring technique
Boring methods are widely used for subsurface investigations to collect samples, in almost all types of soil, for visual inspection or laboratory testing. There are several boring techniques like auger boring, rotary drilling, wash boring, percussion drilling, auger drilling, and test pits that are employed to collect disturbed and undisturbed samples of soils. These boring methods are selected based on the soil types, the efficiency of boring technique, types of soil sample (disturbed or undisturbed), and the availability of facility and accuracy by which soil and groundwater variations can be determined. These techniques are used to take soil samples at a certain practical depth, for example, auger boring collects undisturbed soil sample at a depth of 35m, whereas, the sampling depths for percussion drilling, wash boring, and rotary drilling are around 70m. more detail..

Types of railway sleepers and explain advantage and disadvantage?

WOODEN SLEEPERS:
The sleepers use timber as a raw material to make wooden sleepers. These kinds of sleepers are using since the olden days as they fulfilled all the requirements of an ideal sleeper.
METAL SLEEPERS:
Sleepers usually made of steel or cast iron are known as metal sleepers. Metal sleepers are again classified into steel sleepers and cast-iron sleepers.
CONCRETE SLEEPERS:
The sleepers made of reinforced or prestressed cement concrete are known as concrete sleepers. These kinds of sleepers are more suitable for fast or high-speed trains. We can classify concrete sleepers into Reinforced sleepers and prestressed sleepers
COMPOSITE SLEEPERS:
Sleepers made of waste plastic and rubber are known as composite sleepers. It is also known as plastic sleepers. more detail..

WHAT IS RETAINING WALL?

retaining walls is a structure that is designed and constructed to withstand parallel pressure of soil or hold back soil materials. Traditional retaining walls are designed to resist active earth pressures or hold back soil materials only, which develops the retaining wall concept, which holds pressure. At present, this pressure could be earth filling, liquid pressure, sand, and other granular materials behind the retaining wall structure. To design or build a wall, we consider a variety of factors like we need to understand the location and environmental factors. Building a retaining walls requires advanced planning and careful layout to avoid it becoming a hazard ,or collapsing. more detail..

Posted By: Iqrar Rizvi

How To Calculate Number Of Bricks, Cement And Sand For Brickwork?

Brickwork Calculation & Formula
Standard Size of Brick = 190 x 90 x 90 (mm)
Quality check of brick
Mortar Thickness is = 10 mm
Assume the size of brick work
Wall Size = 1 x 1 x 1 = 1 meter cube
First we are find volume of single brick without mortar
Volume of Brick Without Mortar = 0.19 x 0.09 x 0.09 = 0.001539 meter cube
Than we have to find volume of 1 brick with mortar
Volume of 1 Brick with Mortar = 0.20 x 0.1 x 0.1 = 0.002 meter cube
Number of brick required in brick work Volume = 1
Number of Bricks with mortar = 1/0.002 = 500 Nos.
Quantity of Mortar Volume is = Volume of wall – (Volume of Brick without mortar X Number of brick required )
Quantity of Mortar Volume is = 1 –(0.001539 x 500) = 1-0.7695 = 0.2305 meter cube
