    Sand can be replaced by Quarry dust without any problem.

    • Based on several references, I concluded that sand can be replaced by Quarry dust without highly compromising its durability property.
    • By the experimental investigation, 40% replacement of sand with Quarry dust shows maximum compressive strength and later on, it will decrease after increasing percentage of Quarry Dust in the sand.
    • Workability of concrete decreases as increasing the percentage of Quarry dust
    • Quarry dust is Waste. If we use quarry dust as a replacement of sand, then waste will ultimately reduce.

    Jagannath Puri temple :

    Here I will tell you the reason behind why Jagannath Puri temple not producing its own shadow.

    Reason :

    • Jagannath Puri temple has a dome and the shadow of dome always fall on the building itself so that we can’t able to see it
    • You can clearly understand from the above picture of Jagannath Puri temple that is attached here.
    • Above image shows one way to enter into the Jagannath temple
    • From the image of Jagannath Puri temple, it is clear that the shadow is always falling on the temple

    I hope you agree with my answer.

    Thank you.

There are two waterproofing specification suggested. The cementitious and the polyurethane one. I am afraid because the application is too costly when the choice is wrong. I would like to know the advantage and disadvantage of the two suggested material. ...

    Many types of waterproofing elements, admixtures, and materials are available in the market. Following are some of the examples

    1. Rubberized asphalt
    2. PVC membrane of waterproofing
    3. Polyurethane
    4. Cementitious coating
    5. Bituminous coating or membrane

    Waterproofing of tunnel is the challenging task of the tunnelling industry. Following are the methods of waterproofing used in the tunnelling,

    1. Waterproofing by applied spray
    2. Waterproofing by conventional sheets (sheets jointed by welding)
    3. Use of hybrid materials like waterproof concrete, admixtures mixed Portland cement and aggregate. In this case, admixtures make the concrete water-resistant.
    4. Use of PVC, rubber materials, Vimal PVC materials is globally accepted.

    Waterproofing in the tunnel is aim to give basic support and it makes the inner structure of waterproof for the age of fast and reliable transportation without any type of hazardous situations.

    (FYI : PPC is environment friendly as it consists fly ash in some specific percentages by parts, which is a waste product of burnt coal, usually collected from thermal power plants)

    OPC (m53) attains strength in a shorter time, while PPC (m43) takes longer.
    OPC therefore dries more quickly, but produces more heat during chemical reaction during which it gains strength, as compared to PPC
    Faster is the drying process, more is the risk of cracking of cement, and therefore it need more care and more amount of water for curing in a lesser time.
    PPC on the other hand can attain strength equal to OPC, but takes a longer time.

    For a building slab, PPC is more widely used since it requires less care.
    The strength depends on design mix (the water cement and aggregate ratio) more than type of cement.

    so essentially, If you need construction to take place faster and have means for good curing, you may use OPC.
    But if you need better quality and strength in less effort, use PPC.

    It still depends on the structure’s design requirements and a structural designer’s advice is to be followed.

    Hope this helps, but do consult an engineer before using any type of cement.
    Building construction is a responsible job and needs to be done safely and one must adhere to engineer’s specifications.
