    Here, from a geotechnical perspective you can’t differentiate silt and clay on the basis of grain size because it can be irrelevant to material behaviour.

    Silt and clay are both the result of the physical and chemical breakdown of the minerals in rocks. They main difference is in chemical composition and particle size.

    Silt is composed of silicate minerals, or those containing silicon and oxygen.

    Clay is composed of metal silicates, or silicates with metals like magnesium or aluminum associated with it.

    But in terms of handling the two as part of an experiment, the main discernible difference is particle size. Sand particles are larger than silt particles which are in turn larger than clay particles. Silt particles are about 0.05 to 0.002 millimeters in size. Clay particles are smaller than micrometer in size. So silt particles are too small to really be felt with your fingers like grains of sand. But wet silt will feel very smooth like finely ground baking flour. Clay particles are so small that they will simply feel sticky. You won’t be able to move them around your fingers like silt particles. This stickiness will be the main difference between the two in terms of touch.

    Trigonometry is the best method which can be used to predict the height of the building without using equipment. But if possible than you can also ask to see the builders plan.

    Hi,

    General facts about the lotus temple are already mentioned in the above comments. Here, I describe details of a stone used in this great structure. Encouraged by the lotus flower, the design of Lotus Temple for the House of Worship in New Delhi is composed of 27 free-standing marble-clad “petals” arranged in clusters of three to form nine sides.

    The nine doors of the Lotus Temple open onto a central hall slightly more than 40 meters tall. The surface of the House of Worship is made of white marble from the mountain in Greece, the same marble from which many ancient monuments (including the Parthenon and other Bahas Houses of Worship are built). Along with its nine surrounding ponds and gardens, the Lotus Temple property comprises 26 acres.

    The architect was an Iranian, Fariborz Sahba who now resides in Canada. He was approached in 1976 to design the Lotus Temple and later oversaw its construction. It is one of the highest quality of marble, on which many monuments and idols of Greek Gods and Goddess are made.

    Thank you.

    Ballast also holds the track in place as the trains roll over. It is typically consists of crushed stone, although other less suitable, materials have sometimes been used such as burnt clay.

    • Now it is instead of stone a cement concrete ballast is used. It has a long life and High durability.
    • In ancient days, wood ballast was used.
    • Steel sections are also used as a ballast for railways tracks.

    Why Install it in the slab? A solar panel is not a load bearing structure. You cannot use it for structural purposes. That is simply a bad decision because solar panels are costly and hence they need to be kept safe from damage. We can install them above the slab though if we wish to.

    But again, slabs are horizontal and it’s foolish to install a horizontal solar panel. You’ll never see it that way anywhere except for at the equator. That is because sunlight mostly falls at a slant and to grab maximum intensity, the solar panel has to be perpendicular to the sun rays which will never be horizontal. Beyond the tropics, sunlight will never fall vertical ever in a year. So, no chance of installing a solar panel in the slab. Only if there’s a non load bearing slab cast to hold the solar panel, then it might be possible but that too is a bad idea because it will unnecessarily add to building cost, time and weight.
