What should one do if the slump test fails for a given concrete?

    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.

can we consider drum mixing of concrete same as batch mix or nominal mix?

    Yes. Of course. The method of mixing is not relevant to batching. So long as the quantities and proportions remain what they need to be, drum mixing or hand mixing, both are batch mixing. In fact, in the industry, mostly drums are used for mixing concrete because they save time and labour.

    External walls have to be bear many things like bad weather, stormy winds, temperature variations, etc., So they have to be very tough, impenetrable.

    So the paint to be applied on that should help the wall do so.

    For exterior walls paints must have these properties…..

    1. UV resistance
    2. Water resistancE
    3. Dirt pickup resistance
    4. Thermal insulation
    5. Anti algae & anti fungal property
    6. Wet scrub resistance

    Apart from these many other properties like good sheen, highly elongation, etc must be in high extent in the paint for best performance.

    Paints good to be applied on the outer walls are

    • Latex based
    • satin and eggshell

    Now the brands

    In the current scenario, given the R & D development most companies like Asian paints, Berger, Nerolac have similar quality paint. Slightly ahead would be Dulux.

    The most important thing is not the paint but the painter

    In the case of Exterior Paints Dulux Weathershield, Nerolac Excel, Asian Paints Ultima Protek, and Apex Ultima pitch in. It is good to choose products that suit your requirements rather than brands while choosing paints for interiors and exteriors of houses.

    Place bricks on one top of the other around the concrete shape you want to find its volume.

    First, choose a rectangular shape around the object and then going to the object.

    Then place a sufficiently large sheet of polythene in the space around the concrete object for covering the mold.

    Then take a standard bucket of 25-liter capacity and then slightly pour water within the polythene most do formed. Keep a count of the buckets of water poured till it overflows at the top of the brick wall.

    Measure the inside dimension and depth of the rectangular moat.

    Hi, To solve this query first you must have to know what is a composite structure and RCC structure.

    Composite structure building exists when the two different materials are bound together by any means in a very strong manner so that they can act as a single component give a structural point of view.

    Reinforced cement concrete buildings is a composite material but having low tensile strength and ductility which are encountered by the inclusion of reinforcement having higher tensile strength and ductility. Indian forced cement concrete structures reinforcement abound with cement concrete and both the members are really strong and compression and tension.

    So if I concluded for G+ 12 types of painting reinforced cement concrete structures is used because it has very high tensile and ductility property and gives a high resistance against competition and tension also.

    Hope you get the concept.

Sir As per Is -383 1970, the % of wt retained on 12.5mm must be nil. But when i conducted a sieve analysis of 10mm aggregate, i found out that about 1700 grams were retained on 12.5mm. Now as per ...

    Now you can use the aggregate between sieve size 10mm retaining and passing from 12.5 mm.use locally available materials to reduce cost. Still, the mix design does not change but gives the desired result.

    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.
