Superplasticizers are used to enhance the fluidity of the concrete without adding water. These molecules physically separate the grains of cement by neutralizing their force of attraction. Consequently, the concrete remains fluid for over 2 hours and is easier to use, more resistant and longer lasting. See superplasticizers at work in this close-up video.
