ASTM C-789:
This specification covers single-cell precast reinforced concrete box sections intended to
be used for the construction of culverts and for the conveyance of storm water, industrial
wastes, and sewerage. |
|
ASTM C-822:
Standard terminology relating to concrete pipe and related products. |
|
ASTM C-850:
This specification covers single-cell, precast reinforced concrete box sections with less
than 2' of cover subjected to highway loading and intended to be used for the construction
of culverts and for the conveyance of storm water, industrial wastes, and sewerage. |
|
ASTM C-969:
This practice covers procedures for testing installed precast concrete pipe sewer lines
using either water infiltration or exfiltration acceptance limits to demonstrate the
integrity of the installed materials and construction procedure. |
|
ASTM C-990:
This specification covers joints for precasr concrete pipe and box, and other sections
using preformed flexible joint sealants for use in storm sewers and culverts which are not
intended to operate under internal pressure, or are not subject to infiltration or
exfiltration limits. Joint material used in horizontal applications is intended to prevent
the flow of solids through the joint. |
|
ASTM C-1214: This
test method covers procedures for testing concrete pipe sewer lines when using the
negative air pressure (vacuum) test method to demonstrate the integrity of the installed
material and the construction procedures. This test method covers testing of 4" to 36
" diameter circular concrete pipe sewerlines utilizing gasketed joints. |
|
AWWA C-302: |
|
Concrete Cylinders: This
a test of concrete strength whereby molds are filled with the concrete to be tested via
specification, then curred for a designated period of time, and finally crushed for final
results. |
|
Cores: Cores
are samples drilled from the actual product and crush tested for strength |
|
Dry Cast: Method
of producing concrete products with zero slump concrete either mechanically or poured. |
|
Jacking Pipe:
Special designed reinforced concrete pipe which posesses thrust load capabilities for a
specified project. |
|
Sanitary Sewer:
Sewers designed for the transportation of contaminated waters and wastes to treatment
plants,septic, anaerobic, or aerobic disposal systems. |
|
Storm Sewer:
Sewers designed for the removal of uncontaminated run off waters to retention areas,
creeks, rivers, etc. |
|
T-Lock:
Liners made of a durable plastic composition which have a " T " designed rear
side and is cast into the concrete giving the liner its locking capability and its
name. |
|
2- Z Specification:
This is a specification established by the Water Reclamation District of the Greater
Chicagoland Area for hydrostatic testing of product they purchase. Concrete pipe is
separated a distance of 2 times their 'Z' dimension, filled with water to a prescribed
level, then pressurized to 15lb psi for 2 hours without leaking through the walls or
joints. |
|
3-Edge Bearing: Method
of testing the strength of concrete pipe by squeezing the product on a rack until a
.01" crack appears or squeezing until the product shows complete failure. |
|
Wet Cast:
Method of producing concrete products with greater than zero slump concrete in the poured
fashion. |
