Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or compaction. The effect of superplasticizers lasts only 30 to 60 minutes, depending on the brand and dosage rate, and is followed by a rapid loss in workability. As a result of the slump loss, superplasticizers are usually added to concrete

Adding Lime to Concrete
Lime can also be used simply as an additive in other concrete mixes, as well as cement mortars. For mortars, this process can take time, as quicklime has to be mixed with water to create a putty which will then have to mature, so other mortar plasticizers will often be used instead to achieve the same effect.
