Seven Must-Use Concrete Admixtures (Additives)
Set retarding concrete admixtures are used to delay the chemical reaction that takes place when the concrete starts the setting process. These types of concrete admixtures are commonly used to reduce the effect of high temperatures that could produce a faster initial setting of concrete. Set retarding admixtures are used in concrete pavement construction, allowing more time for finishing concrete pavements, reducing additional costs to place a new concrete batch plant on the job site and helps e
Flowing Concrete| Concrete Construction Magazine
Admixtures used for flowing concrete are sometimes called high range water reducers and sometimes superplasticizers. Flowing concrete can also be made, however, by using two separate conventional admixtures at the same time; these jointly serve to provide the needed slump and control the set for the particular conditions of the job.

A Contractor’s Guide to Superplasticizers
Plant or Site Addition One admixture manufacture r states that if haul times are part i c - ularly long, a Type G HRWR added at the plant can minimize pro b - lems associated with ASTM C 94’s limitations on delive r y time and mixer re vo l u t i o n s. The re t a r der in a Type G will also delay the set for that long run. If unexpected delays
