What is Prestressed concrete structure? Defination 1). Prestressed concrete is a method for overcoming concrete\'s natural weakness in tension. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete. Defination 2). Prestressed concrete is a concrete construction material which is placed under compression prior to it supporting any applied loads (i.e. \"pre\" stressed). Defination 3). A more technical definition is \"Structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads.
DIFFERENCE BETWEEN WEIGHT AND MASS In physics the standard unit of weight is Newton, and the standard unit of mass is kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N. Email This BlogThis!

Steel bar weight calculation: [1]- For Round bar: Weight in Kg = Diameter(mm) x Diameter(mm) x Length(meter) / 162.2 As for example:- I have a steel rod of 8mm diameter with 1 meter length. (8*8/162.2)*1 (64/162.2)*1 (0.394)*1 0.394 [2]- For square and Rectangular bar: Weight in Kg = Width(meter) x Thickness(mm) x Length(meter) x 7.85
