    Properties of alkali-activated fly ash :

     I studied different research papers based on the above topic and I concluded that :

    • The mortar and concrete made with Portland cement, free activated fly ash develop a highest mechanical strength
    • Less time required to gain enough strength
    • It has a moderate modulus of elasticity
    • Better Bond formation of Steel reinforcement
    • Its shrinkage capacity is very less as compared to ordinary Portland cement concrete

    Optimisation of alkali-activated fly ash :

    • Actually conductive alkali-activated Ash is formed using carbon fibres
    • Optimisation of alkali-activated fly ash is done when we use 0.3% Carbon fibre content 25 to 30 per cent ceramsite content and 70% slag content

    Thank you.

    The main purpose of the clearstory window is to provide fresh air and natural light.

    The clearstory window should be larger as possible.

    Advantages

    • Better air circulation and natural light emitting
    • Good aesthetic view
    • Due to higher sill level better privacy
    • Save electricity due to natural light
    • Better environment formation.

    Disadvantages

    • Wall slab junction become critical at opening of clearstory
    • Costly design
    • Due to hight sunlight, there is may be heat problem.

    Contour farming is an agricultural practice where steps are cut out on a sloped field so as to provide steps of flat land (same contour) for cultivation.

    Contour farming is an agricultural practice where steps are cut out on a sloped field so as to provide steps of flat land (same contour) for cultivation. The potential benefits are a check on erosion, better rainfall usage, more infiltration, and reduction in the need for irrigation.

    It is feasible on all slopy regions to accept on those with highly erodible soils and soils that allow little infiltration.

    it is a very approximate form of levelling in which sights are taken as largeas possible. In this method a line of levels is run to determine approximately reduced levelsof the points carried out with more rapidly and less precision. It is a levelling that is done toconnect benchmark to the starting point of the survey line. In this levelling only back sightand fore sight readings are taken and auto level is moved strictly on the line joining benchmark and starting point of survey line

    The curve number method is an adaptable and widely used for runoff estimation. This method is important properties of the watershed, specifically soil permeability, land use and antecedent soil water conditions which take into consideration. Thus, straightforward methods of calculating runoff can tell you the amount of water that storms bring to the earth. For a given surface area such as a roof or yard, multiply the area by the inches of rainfall and divide by 231 to obtain the runoff in gallons.

What are the advantages of optical reading theodolites over ordinary theodolites? Also, mention types of optical reading theodolite?

    Theodolites with optical instruments have advantage over other layout tools. They have more precise measurements, they are unaffected by wind or other weather factors, and they can be used on both flat ground and sloped ground.
