    Aditya,

    Here you are asking about Life Cycle Assessment (LCA) of structure.

    The life span of structure will vary according to the type of structure.

    There is no formula available to calculate the life span of any structure.

    Different parameters we should take into mind while doing a calculation of life span of structure, they are as follows;

    Building Construction Material:

    • RCC structure

    Structural Design:

    • Mostly influencing parameter.
    • Vary as per Building Construction Material.

    The locality of structure construction: E

    • Earthquake-prone area
    • HFL (High Flood Level) zone

    Height of structure.

     Kindly noted that I have attached one photo of the life span of various structures.

    Weight of different ingredient of Mortar 1:3 –

    Here, I will give you a simple way to calculate the weight of different ingredients in a mortar.

    • The mortar ratio is 1:3, it simply means that the 1 part of cement is present and 3 part of sand is present in that type of mortar.
    • Consider, w/c ratio = 0.4
    • We are doing all calculation for 1kg of mortar.

    1 part = 1/(0.4+1+3) = 0.227

    Water Required =0.25 x 0.227 = 0.056kg

    Cement= 0.2247 kg

    Sand =3.15 x0.227 = 0.717 kg

    Thank You.

    Laterite is a rock and soil type substance which contain a high amount of iron and aluminium. It is commonly formed in hot and wet tropical areas. Mass Density of Laterite = 1019 kg/ m3 1 metric ton=1000kg Hence,  1m3 laterite = 1.019 metric ton Thank You.

    CORROSION refers to an electrochemical reaction between a metal and its environment. Steel will readily rust unless it is coated. Corrosion occurs when steel reacts with chloride ions (Cl-), CO2 in the presence of a toxic environment. Thus, corrosion is uneven erosion/pitting of metal surface due to intense rusting and is also harmful to the service performance of rebar.

    There are many ways of reducing the risk of corrosion-related distress in concrete. The first defencing layer is concrete, which should be thick and dense. Also, the cracks should be minimized. The concrete cover should be used appropriately.

    An additional measure for corrosion-resistant is that corrosion inhibiting admixtures should be used. Epoxy coatings should be done on rebar, which acts as a physical barrier and also isolates the steel from oxygen, moisture, and chloride ions (which are the three primary elements needed for corrosion to occur).

    The most average time to build a multi family house which varies the number of units in a building.

    In 2014 building the twenty or more units took near about 15 months to complete from the time of obtaining permits. And properties with 10 to 19 units physically finished in 13.6 months whereas 5 to 9 unit building came in at  11.5 months.

    The average time from permits to start does not follow the same pattern with respect to property size. Properties with 10 to 19 units had the longest average waiting period.

    No. Load Bearing Structure Frame Structure
    1. Almost all the walls are load bearing walls. None of the wall are load bearing. They serve the same purpose as partition or screen.
    2. Almost all the should be provided with foundation None of the walls are provided with any type of foundation. Walls do not go below the plinth beam.
    3. Load bearing walls are taken deep into the subsoil foundation. Only column are taken deep into subsoil and provided with foundation footing.
    4. Any load bearing wall should have minimum thickness of 200 mm. Exterior wall subjected to weathering elements are generally 200 mm thick. All other wall can be 100 mm thick or even thinner.
    5. Wall are usually constructed of bricks or stone. Column supporting beam supporting slab are all of R.C. C.
    6. In a multi-storeyed building for every wall in the floor above there must be a corresponding wall in continuation in the floor below to support it. There is no such necessity. As none of the walls are load bearing. Every floor may have wall independent of the one below it.
    7. In a multi – storeyed building the thickness of the wall increase as we descend from a floor above to one below it. These walls do not take the load and need not be thicker. They may not even continue in the floor below.
    8. A load bearing wall once constructed shall remain in position and should never be dismantled in full or part. The wall of framed structure can be displaced at will as they are lighter and non load bearing.
    9. This type of construction does not favor toomany openings for windows, doors, ventilation etc., in the ground floor as required for show room etc., as the load bearing length of wall is considerably reduced. The space between column can remains as open space as the case with multi – storeyed residential flats where the ground floor is left with no walls for easy parking of vehicle.
    10. In case of multi – storeyed buildings, the room area is reduced as we go down due to thicker walls. Thickness of wall remains uniform, therefore the carpet area in any floor remains the same.
    11. Plans of the different floors must be the same. Very little changes are only possible between one floor and the one above. Plans of different floor are independent of each floor. The ground floor may have a commercial complex, first floor an office or a bank and second floor onward of residential complexes of different types of plans and function within the same building.
    12. May not withstand seismic forces and other forces and other type of vibration because composed of different blocks as bricks and stones being bonded together. More rigid and withstand seismic forces because of the entire frame of column, beam and slabs act as one unit of R.C.C.

How the slope system in pipes and drains works and how to check and maintain the same at construction sites? What are the methods for the same? What is the mean of 1:4 slope for pipes and drains?

    Slopes in pipes and drains are decided by quantity of water or wastewater to be transported through it by the action of gravity in cumecs. Following things influence the slopes of drains and pipes:

    1. Quantity of water to be transported

    2. Size or diameter of the pipe

    3. Distance the water to be carried

    4. Velocity or the pressure required for the water at the outlet, if any

    Slopes of drains and pipes at construction site is checked by dumpy level or level machines. For the same, you have to calculate depth of pipes at different intervals.

    Suppose, 1:4 slope of the pipe is required as per drawing (as mentioned by you), then the depth of pipe at should have a difference of 1 m from start of the pipe to the end of pipe at 4m. If you want to know the depth of pipe at 2m length, then it will be half of the end position, i.e. 0.5m. These are calculated based on triangle.

    Slopes are always mentioned w.r.t. a reference point. Consider your reference point as a levelled surface. Then length of the pipe required will be length of the triangle, base will be the depth required from the start to end of the pipe. Now you can divide the triangle at different point and calculate the depth required at different locations of the pipeline or drain system.

    I will provide your more details with figures soon.
