DEVELOPMENTS IN SPECIFICATION AND CONTROL

Alkali-carbonate rock reactions have been regarded as capable of producting damage in concrete. Such damage may be prevented by avoiding the use of reactive rock. Rock may be classed as reactive based on its service record, its behavior in the rock cylinder test (ASTM C586), or its behavior in concrete test specimens. Alternatively it has been suggested that damages may be prevented, as in alkali- silica reaction, by using low-alkali cement or a pozzolan or both. A supply of reactive rock may be rendered harmless by being diluted with nonreactive rock, or a source of rock may be rendered satisfactory by selective quarrying to discard reactive rock. Construction practices such as vapor barriers below pavements and more closely spaced expansion joints may assist in controlling the effects. procedures used by the Corps of Engineers to detect reactive carbonate rock are cited and the measures to be taken are quoted.
