◍ When a member is designed so that under the working load there are no
tensile stresses in it, then the concrete is said to be fully prestressed. On the
other hand, if tensile stresses are allowed to be produced in the member
under working load, then it is termed partially prestressed (the process of
applying a percentage of the final force at some earilier time than the normal
72 hours).
Answer: For partial prestressing additional mild steel rebar may be required
to control cracking under tension. For economic reasons, partial prestressing
is most common for of prestressing used in structures. Sufficient
prestressing steel is used to offset most of the member self-weight and other
sustained dead loads. Occasionally a small portion of live load is also
included. The tension produced by the remainder of live load is resisted by
the combination of stressed and non-stressed steel, resulting in economical
structures. THE BONDED STEEL REBAR assures control of the crack
, width and distribution, should secondary effects or overloading cause the
member to crack.

◍ Proctor Tests.
Answer: The standard Proctor test was developed in early 1930s by RR
Proctor, a field engineer for the City of Los Angeles. Applying heavy
weight to a completely dry soil sample won't acieve much increase in
density. When water is added it's much easier to increase the density. Water
, acts as a lubricant. The standard Proctor test is usually specified for fill
material designated for use under building slabs and sidewalks, and in utility
trenches under grassy areas. A sampl of the proposed fill material is crushed
so it can pass thru a 3/4inch sieve. A steel cylinder mold is filled with the
sample in 3 layers. Each layer is struck 25 times with a 5.5lb, 2inch diameter
hammer before the next layer is added.

most complex of the 3 types. Formal meetings must be held for any major
decision.
◍ Head lap, top lap and exposure.
Answer: The 2 inch lap where the shingles are three layers thick is the lead
lap. Top lap is where shingles are at least two layers thick. Head lap is
where shingles are three layers thick.Top Lap = W-E or E+HLHead Lap =
TL -E or W -2EExposure = (W-HL) / 2
