    It is between 0.5% to 1% by volume.  It's better to use density by volume and not by weight because 0.5% to 1% by volume is necessary to maintain electrical conductivity properly. The weight density will then depend on the fibre used. That will fall between 1.5 to 2 g/cc.

    Well, one way would be to 1) First lay the footings and colomns in the extension area 2) then knock of the wall 3) underpin or scaffold the beams/girders above the wall 4) drill into the outer face at the joints of beams, coloumns from where the extension is to be done 5) drive in new reinforcementRead more

    Well, one way would be to

    1) First lay the footings and colomns in the extension area

    2) then knock of the wall

    3) underpin or scaffold the beams/girders above the wall

    4) drill into the outer face at the joints of beams, coloumns from where the extension is to be done

    5) drive in new reinforcement bars onto the drilled holes and grout

    6) bend them up to make a crank extension

    7) do the same to the new colmns

    8) put up the formwork for beams and cast them with crank reinforcement, put up the formwork for floors or roof and cast them in the same way

    9) build walls, doors, panels, etc at the new open faces after extension.

    PS : This is just a suggestion. It’s not tried and tested. For a cost estimate, a contractor or estimator might help.

    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.

    The concrete pressure on formwork can be calculated without measurement. However, I can see that you'd like to be sure about it with experimental verification.

    The purpose of doing a CBR test is to find out the California Bearing Ratio (CBR) of a material which has to be used for the subgrade of flexible pavements. The actual quantity that concerns the strength of the subgrade material is Resilient Modulus though. CBR is different from it but hugely corellated. Also, in literature there are curves plotted for the CBR against the expected traffic (million axles per year) for every subgrade thickness. We can read the required thickness for which we need to design the subgrade layer if we know the CBR of our material and the design traffic. So, it is preferred not to get into the complexity of resilient modulus calculation and use CBR instead which can be easily tested on site.

    By definition, CBR is the ratio of the opposing bearing stress experienced by a standard penetrator when penetrated by a distance of 2.5 cm into the rock to the actual crushing strength of the rock in percentage.

    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.

    Nano concrete is concrete along with cement particles in the size range of 0 to 100nm either added later or included in to cent formulation. These small particles tend to fill up all nanopores and increase the quality of concrete drastically even with a small addition of 1% to 2% of cement weight. ARead more

    Nano concrete is concrete along with cement particles in the size range of 0 to 100nm either added later or included in to cent formulation. These small particles tend to fill up all nanopores and increase the quality of concrete drastically even with a small addition of 1% to 2% of cement weight.

    A few properties of it are :

    • Increased strength (70 to 100 MPa in 28 days)
    • Increased durability because of lesser pores filled with water.
    • Better workability of the concrete mix.
    • Reduced shrinkage losses and drying shrinkage

    Plain cement concrete (PCC) is simply concrete by definition. It is cement + water + fine aggregates + coarse aggregates. It is the ordinary concrete without any kind of reinforcement. However, pozzolans, admixtures, etc. may be included in the mix.

    Reinforced cement concrete (RCC) is PCC + reinforcement. The reinforcement is generally steel bars bent and laid into the desired shape and orientation. The reinforcement can be both tensile or compressive reinforcement depending upon the situation. However, mostly both are used in any structural member. It is rare to find an RCC structure with only either tensile or compressive reinforcement.

    In terms of strength, naturally, RCC is stronger because the reinforcement helps in load-carrying capacity.

    PCC is weaker and is only used for layering surfaces like plastering work or flooring and most importantly in the layering if excavation to cast footings.
