How does a slump test check strength?

Slump check does not measure strength. It measures workability. Workability is the ease with which concrete can be placed in position.

Correct as far as it goes! Slump refers to workability however it is also, all telling as to the water content of the mix. The more water, the easier it will work! Problem becomes, too much water will increase the porosity making the concrete weak and susceptible to early degradation because contaminates are able to enter and commence corrosion of embedded steel.

A concrete that is easy to work that has a high water content [ more than .40 ] is known for shrinkage cracking due to rapid evaporation of the high water content. These cracks caused by rapid loss of water decrease compressive strength and invite early corrosion. This type of concrete also experiences, curling and ASR as well as efflorescence in a very short time period.

Strength is a function of correct hydration, slow internal curing and careful design of a mix for the intended service criteria and not a whole lot to do with slump!

triangle

ANS 2 - There is no 'best shape' - each bridge is designed for a particular place and can be almost any kind of construction.

Why trusses are used in railways bridge?

With trusses you can obtain high strength of the bridge using rather thin and simple (i.e. cheap) elements. A drawback is that the required height of the side of the bridge rises with the span of the bridge, so trusses become less effective for larger spans compared to the cable bridges. Railway bridges have to sustain higher load than road bridges (trains are heavier), so trusses are an efficient design to increase strength.

Why do you have truss bridges?

Truss bridges are lighter than beam girder bridges. They take up more height but are strong and carry loadd in tension and compression rather than bending.

What is crs bar tech?

If I under stand your question correctly, you are asking a technical question : What is CRS bar?

CRS is Corrosion Resistant Steel reinforcement bars used in Reinforced Cement Concrete. This is not as good as Stainless steel, but better than ordinary Reinforcement bars and is manufactured by some manufacturers like Tata Steel (in India) by giving some surface chemical treatment to the bars.

How does a cantilever bridge work?

like it an awesome bridge

ANS 2 - It's called 'cantilever' because of the way it was built. Nothing to do with 'how it works' - It spans a gap just like any other bridge.
