    What is the reason behind the initial setting time of cement should not be less that 30min.?

    Initial setting time of various types of cement: The value of the initial setting time is different for a different type of cement. The initial setting time of Quick setting cement is only 5 minute. The initial setting time of low heat cement is 60 minutes But usually, another type of cement has 30mRead more

    Initial setting time of various types of cement:

    • The value of the initial setting time is different for a different type of cement.
    • The initial setting time of Quick setting cement is only 5 minute.
    • The initial setting time of low heat cement is 60 minutes
    • But usually, another type of cement has 30minutes is the value of initial setting time.

    Please refer the above image for knowing the values of initial setting time and final setting time for various types of cement.

    Thank you.

    Here, consider lens or mirror at the origin. Now, all the distances measured in the direction of incident rays are positive and distances measured in the direction opposite to the direction of incident rays are negative. All distances have to be measured from the lens or mirror. For example object distance measured from lens or mirror is measured in the direction opposite to direction of incident rays hence, in these case object distance u is negative. The paraxial parallel rays are focused on the right hand side of convex lens. See, this distance f is measured in the direction of incident rays . Hence, focal length of convex lens is positive. But, we can see that focal length of concave mirror is negative. It’s radius of curvature is also negative. The radius of curvature of first surface of convex lens is positive, but radius of curvature of it’s second surface is negative. You can see that radius of curvature and focal length of concave mirror are negative.

    The Golden Ratio is an irrational number with never-ending infinite numbers of digits, 1.618033988749895..., which are highly confusing and misleading. It is a linear number and represents only two dimensions of the object. Drawing It Here is one way to draw a rectangle with the Golden Ratio: Draw aRead more

    The Golden Ratio is an irrational number with never-ending infinite numbers of digits, 1.618033988749895…, which are highly confusing and misleading. It is a linear number and represents only two dimensions of the object.

    Drawing It

    Here is one way to draw a rectangle with the Golden Ratio:

    • Draw a square (of size “1”)
    • Place a dot half way along one side
    • Draw a line from that point to an opposite corner (it will be √5/2 in length)
    • Turn that line so that it runs along the square’s side

    Then you can extend the square to be a rectangle with the Golden Ratio.

    If we talk about malleability and ductility both are connected or related. A malleable material is one in which a thin sheet can be easily formed by hammering or rolling.

    If we talk about malleability and ductility both are connected or related. A malleable material is one in which a thin sheet can be easily formed by hammering or rolling. In other words, the material has the ability to deform under compressive stress. And here ductility is the ability of the solid material to deform under tensile stress. Practically, a ductile material is a material that can easily be stretched into a wire when pulled.

    Arch Dam ; Arch dam can be defined as a solid wall, curved in plan, standing across the entire width of the river valley in a single span.

    Arch Dam ;

    Arch dam can be defined as a solid wall, curved in plan, standing across the entire width of the river valley in a single span. The body of arch dam is generally made of cement concrete. Thus, arch dam is just a curved beam, the ends of which are restrained and the way in which the loads are resisted is termed a arch action.

     

    Buttress Dam ;

    A buttress dam or hollow dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of buttresses or supports. A buttress dam envisages to reduce the total volume of concrete by constricting the material where the stresses are higher and other undesirable features of gravity dam but has higher cement content per cubic metre of concrete than a gravity dam.
