Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content. If a change is noted in the mill certificate, air-entraining agent dosages may need adjustment. Above 0.60%, alkali changes of 0.1% can be significant.

High temperatures also affect the compressive strength of concrete. Above 212º F, the cement paste begins to dehydrate (loses chemically combined water of hydration), which gradually weakens the paste and paste-aggregate bond. The temperature that concrete has reached often can be determined by observing color changes in the aggregate.

The control strip is left open to allow each slab region to shorten, and is then closed by filling it with concrete. Closure strips are sometimes an alternative to expansion joints when a building length exceeds 250 ft (76 m).3 They’re used extensively in unbonded post tensioned structures to minimize the movement and restraint developed during post-tensioning and due to early volume changes.
