mortar and deposits them on the surface. Also used as the name for these
deposits.
Elastic
Able to return to its original form after the removal of stress.
Elastic shortening
The shortening of a member in pre-stressed concrete that occurs on
the application of forces induced by pre-stressing. See pre-stressed
concrete.
End plugs
Heavy-gauge metal cap ends for the straight steel forms.
Expansion joint
A surface divider joint that provides space for the surface to expand.
It is usually composed of a fibrous material (~1/2" thick) and often
installed in and around a concrete slab to permit it to move up and
down (seasonally) along the non-moving foundation wall.
Expansive-cement concrete
A concrete made from expansive cement for the purpose of reducing or
controlling volume changes that occur during curing. See curing.
Exposed aggregate
See Aggregate, exposed.
Exposed aggregate finish
A method of finishing concrete which washes the cement/sand mixture
off the top layer of the aggregate - usually gravel. It is often used
in driveways, patios and other exterior surfaces. See Aggregate,
exposed.
Extension chute
An additional chute used by a concrete contractor to extend the length
of the existing chutes from a ready-mix concrete truck. They are frequently
used to pour floors. See agitator
truck and ready-mixed
concrete.
Extension pocket
Concrete forming accessories used to hold a form over a trench without
adding additional supports underneath. This device consists of a stake
pocket that is attached to an adjustable horizontal brace and then attaches
to the stake pocket of the form. This device allows the forms to be
set in areas that have been trenched by allowing the form bracing to
"float" above and over the trench.
