tests on aggregates for concrete

TTL Associates, Inc. Concrete Testing Inspection

Concrete can be tested in the plastic state for slump, air content or unit weight. In addition, test cylinders and beams can be cast to determine compressive and flexural strength. Concrete form and reinforcing steel inspection is also provided along with concrete condition surveys, inspections and mix design.

D-Cracking Pavements Concrete Construction Magazine

Concrete pavement D-cracking is a terminal condition. Once it starts, there's no known cure. The cause is known--coarse aggregates susceptible to freezing and thawing deterioration. But the only way to prevent D-cracking is to avoid using these aggregates in concrete pavements. Aggregates that cause

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (Y. in.), and
