Type three
|
|
admixtures are used in concrete to
|
Delay hardening

in slub placement, what comes directly before concrete floating?
|
Strike-off
|
|
concrete slab shrinkage cracks are primarily reduced by:
|
Adding wiremesh rebar
|
|
insulating concrete forms (ICFs):
|
Place insulation at the core of the wall
|
|
re-shoring is:
|
A set of supports for lower floors as higher floors are poured

|
|
after two precast concrete elements joined, exposed metal connectors are usually:
|
Dry packed with Portland cement grout
|
