The chemical grout family includes sodium silicate, acrylic gels and polyurethane expansive foams. … is accomplished through the control of the water/cement ratio and almost always a superplasticizer is added to reduce viscosity. While additives can be added to slow the cure time, once mixed with water, cement grouts will begin to cure and …
Selection of Superplasticizers for High-Performance Concrete
Superplasticizers are used to fluidify the concrete in the field. Most of the superplasticizers helped to maintain high slump values for a time of 30 to 45 minutes. But some of the Portland cement do no behave well with the use of superplasticizers. This problem is understood only by the detailed …
Use of Water Reducers, Retarders, and Superplasticizer
Typical dosage of superplasticizers used for increasing the workability of concrete ranges from 1 to 3 liters per cubic meter of concrete where liquid superplasticizers contained about 40 % of active material. In reducing the water cement ratio, higher dosage is used, that is from 5 to 20 liters per cubic meter of concrete.

Bonding agents are applied to existing concrete surfaces immediately before the new concrete is placed. Grouting admixtures alter the properties of grout for specific applications. Aluminum powder and other gas-forming materials are sometimes added to concrete and grout to cause an expansion of the mixture prior to hardening.
