My current work status is student. I'm studying civil engineering. And now I'm in my final year.

Gypsum:

• It acts as a retarding agent in cement, which prevents the flash setting of cement.
• It has another advantage that it is fire resistant also.
• It also influences the strength, strength development, and volume stability of cement. It simply... (More)

Using the following ways,

1. Usage of maximum energy-efficient lighting
2. Usage of a smarter lighting system.
3. Sodium lamp replaced by LED’s in a first way
4. Use artificial light as per requirement in the second way

Thanks.

Chrome corundum brick is initially formed in green colour. If the Cr2O3 content of chrome corundum brick is about 3%, the colour it will take is light red and the purplish-red colour is formed at about 8%. If the Cr2O3... (More)

The maximum degree of curve or smallest radius for a railroad is 3 degrees on a new main line track with a maximum grade of 1% compensated at 0.04% per degree of curve; therefore a grade in a 3 degree... (More)

We can reduce the emission of gases in the construction industry by applying the following steps;

1- By implementing smart and efficient materials which are more durable and cheap. Also, it causes less pollution while they are manufacturing in the... (More)

Skin reinforcement is nothing but reinforcement which have lens cover, and the function of skin reinforcement is to prevent cracking due to various forces like shrinkage, bending, weathering action, etc.

Sand Face Plaster is a layer of cement sand mortar applied on the brickwork which also works as a damp proof coat. This plaster is used as a final touch for surfaces like walls and ceilings. Up to some point,... (More)

For residential building standard size of roof height is given as 10 feet. And for commercial building it is given as 10 to 12 feet.

If the slump test fails for concrete then immediately reject that concrete because high amount of water can decrease the durability of the concrete. But dont add water if the slump test fails.

In accordance to the latest revision of IS 1786(2008) Fe 500D is a new introduction of deformed steel bar that has same specified minimum 0.2 percent proof stress/yield stress but with enhanced specified minimum percentage elongation.

Helical reinforcement is capable of protecting columns or piles against seismic loads.

Whenever the column reaches the failure condition, then concrete outside hoops will crack & it falls off first, followed by the whole columns’ eventual failure.

The more important... (More)

Plasticisers are used for following purposes :

1. Increasing the workability of the mix.
2. Decreasing the water content.
3. Certain types can be used as retarding agents.
4. As Air entraining agents
5. Superplasticisers are used when high workability is in demand.

Various manufacturers... (More)

REQUIREMENTS OF GOOD BUILDING STONES

The following are the quality requirements of good building stones:

1. STRENGTH

Generally most of the building stones have high strength to resist the load coming on it. Therefore it is not of prime concern... (More)

The tests conducted for acid-resistant bricks are:

1. Water absorption
2. Flexural strength
3. Compressive strength
4. Acid resistance

To know more about acid-resistant brick and the detailed test procedure, read the article given below-
Acid-Resistant Bricks: Properties, Types, Tests, and Advantages17

The maximum dry density of  Granular Sub Base used in Road Construction must be  2100 Kg/Cum.
The maximum dry density of Wet Mix Macadam used in Road Construction must be 2230 Kg/Cum.

The reduction in strength of a member due to cyclic loading is called fatigue. However, the fatigue reaches a constant point over a time. This point is called the endurance limit. The reduction in strength of the member, i.e., fatigue,... (More)

Malleability is a related to ductility,

Malleability is a property, which thin sheet can be formed by hammering and rolling very easily.

When ductility is ability to deform of material when tensile force is applied to that material.

CBR test is carried out to find the strength of a material like aggregate and soil. But in general, we do it for soil. Therefore, to find the strength of soil, the California Bearing Ratio test is performed. The design... (More)

Generally, for cheap and on-site production of waterproofing, a combination of aggregate chippings and aggregate dust is combined with bitumen emulsion and is completely laid over the constructed road. The emulsion itself can vary in type.

Other than this, there... (More)
