This is not the authority's first encounter with a bad batch of concrete.

This is done simply and efficiently, using batches of concrete between the cans.

In mid-April, a batch of concrete had to be replaced after it failed a stress test.

Each batch of concrete comes out a different color, so no one shade of paint can match every surface.

"My father would mix a batch of concrete for me to play with, and we would work side by side," she said.

Early into construction a batch of concrete failed a routine strength test causing construction to come to a complete halt.

Slump is normally measured by filling an "Abrams cone" with a sample from a fresh batch of concrete.

The book takes place over the course of one day and describes the attempts of a group of shock workers to break the record for most batches of concrete mixed in a day.

Workability can be measured by the concrete slump test, a simplistic measure of the plasticity of a fresh batch of concrete following the ASTM C 143 or EN 12350-2 test standards.

Pour about one-quarter of the last batch of concrete (you should have this much left over) beneath the side of the slab opposite the one that was raised, and force the mixture beneath the slab using a narrow board.

Special mixes of concrete are made to withstand the extreme pressures of the massive building weight; as is typical with reinforced concrete construction, each batch of concrete used was tested to ensure it could withstand certain pressures.

In a 2002 inspection of Quaker Ridge, district facilities personnel discovered cracking and deteriorating concrete - the result of excessive moisture and a bad batch of concrete with beach sand - on a slab in a crawl space underneath the school.
