COARSE AGGREGATE: (1) For concrete: aggregate which retained on the No. 4 sieve (4.76 mm). (2) For bituminous material: aggregate which retained on a sieve of 3 mm square opening

COHESIVE SOIL: A sticky soil like clay or clayey silt

CONCRETE: A mixture of water, sand, stone, and a binder (Usually portland cement) whichhardens to a stonelike mass. There are four types of portland cement

Type I: Normal portland cement: This is a general-purpose cement used whenever

sulfate hazards are absent and when the heat of hydration will not produce

objectionable rises in temperature. Typical uses are sidewalks, pavement, beams

columns and culverts

Type II: Modified portland cement (Sulfate-resistant portland cement): This type

of cement is applicable when exposure to severe sulfate concentration is expected

generally used in hot weather in the construction of large concrete structures. Its heat

rate and total heat generation are lower than for normal portland cement.

Type III: High-early strength portland cement: This type develops its strength

quickly. It is suitable for use when the structure must be put into early use or when

long-term protection against cold temperatures is not feasible. Its shrinkage rate,

however, is higher than for types I and II, and extensive cracking may result.

Type IV: Low-heat portland cement: For extensive concrete structures, such as

gravity dams, low-heat cement is required to minimize the curing heat. The ultimate

strength also develops more slowly than for the other types

CONDUIT: Any open channel, pipe, etc., for flowing fluid. A pipe or tube in which smallerpipes, tubes, or electrical conductors are inserted or are to be inserted

CONTRACTOR: The person or persons, firm, partnership, corporation, or combination  

thereof, private or municipal, who have entered into a contract with the State (Client)
