    Let’s discuss some important precautions that we should keep in our mind while doing hand mixing of concrete. They are as follows ;

    • Hand mixing should be used for small concrete preparation
    • Hand mixing platform should be watertight and it should be impervious
    • Mixing platform should be of concrete platform or brick floor to avoid the addition of extra water in our concrete
    • Water should be added in some interval in concrete while hand mixing
    • Avoid large sizes of buckets for the measurement purpose
    • Labours should wear a mask to avoid some respiratory diseases

    Steps to follow for doing hand mixing of concrete :

    • Doing proper batching of all the ingredients of concrete and spread them evenly
    • Add cement with Sand and mix them for throughout
    • Mixing process should continue until we get the homogeneous colour
    • Then add coarse aggregate into it and again mix it appropriately
    • For mixing forward and backward movement of shovel have to be done
    • Then at the centre, one hollow circular space is formed for the addition of water
    • While doing hand mixing 5 to 10% of the extra amount of cement should be added
    • PPE( Personal Protective Equipment) should be wear by labour while doing hand mixing

    It is otherwise called “Concealed Beam”.

    The Hidden beam is a way to depict the load scattering on to supporting slab.

    Hidden beams are for the most part embedded inside the suspended slabs where section thickness is extensive.

    In the event that the cantilever beam is with a Hidden beam, it can not go about as an unadulterated beam and will just circulate the loads over the slab area and it can not be considered as basically bolstered one.

    – as it were, “The hidden beam isn’t a beam and the main way to spread the focused loads of the walls on the piece region. The Hidden beam is a virtual beam that was started by somebody to utilize the Beam free headroom.

    *Hidden beam is given among living and feasting spaces right angle to one another. This gives a perfect and level roof surface that is useful for the look.

    Basically it makes a spanning issue, as spans for structural help are at a right angle to one another. This implies one slab structurally basically rests over the other.

    Concealed beam between balcony and room is normal to encourage simple consideration of the gallery into room space later.

    Purpose

    To scatter loads on supporting slabs.
    To break a wide board of slab to a significant size.
    To accomplish max floor height.
    To make room for electro mech ventilation work.
    To improve architectural aesthetic appearance by giving flawless and leveled ceiling surface

    Advantages

    It saves floor height clearance.
    It permits if brickwork to be built over a slab.
    It is economical
    It gives the better interior appearance

    Disadvantages

    The disservice of the concealed beam is that it’s extensively low malleability in view of the height reinforcement proportion that is given to repay to depth limitation explicitly at column connection.

    Fundamentally it makes a traversing issue, as spans for structural support are in a correct right to one another. This implies one slab fundamentally rests over the other.

    Sir,

    All the collected data is very useful for the properties of soil gradation, density, bearing capacity, shrink and swell potential, lateral earth pressure and groundwater condition.

    Dry density is used to determine the appropriate structural design for the pool shell.

    Most critical soil property is swell potential which is highly influencing factor for structural design.

    Capital costs are fixed, one time expenses incurred on the purchase of land, buildings, construction and equipment used in the production of goods or in the rendering of services. In other words it is the total cost needed to bring a project to a commercially operable status.

    Assume one work is awarded to a contractor on item rate basis. During the execution of work, the necessity arises to do some works which are not given in the contract, but the contractor has been requested to carry out such works and payment will be made after supplemental rates and agreement are executed

    This is extra. work

    Example Providing stainless steel handrails instead of aluminum handrails

    Here extra work is provision of stainless steel handrails

    During the execution of foundation work, the quantity given in the agreement is exceeding due to actual type of soil

    Here additional quantity of earthwork, filling, RR work will be coming which are needed

    Usually in the agreement itself it will be mentioned that the rates are applicable up to 5% more or less besides quantity

    Here the additional work comes.

    A fire brick, firebrick, or refractory is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency.

    There are mainly three varieties of refractory bricks;

    a) Acid Refractories
    i. Ordinary Fire Bricks
    ii. Silica Bricks
    iii. Ganister Bricks

    b) Basic Refractories
    i. Magnesite Bricks
    ii. Dolomite Bricks
    iii. Bauxite Bricks

    c) Neutral Refractories
    i. Chromite Bricks
    ii. Carborundum
    iii. Chrome Magnesite Bricks
    iv. Spinal Bricks
