Types and Uses of Geotextiles - The Balance .

Geotextiles are used in civil construction projects for soil fills to improve soil characteristics. Geotextiles make poor soil more manageable, enabling construction in places that would otherwise be unsuitable. Geotextiles are ideal materials for many infrastructure works, such as roads, harbors, landfills, drainage structures, and other civil projects.

Chemical Admixtures - Portland Cement Association

Retarders keep concrete workable during placement and delay the initial set of concrete. Most retarders also function as water reducers and may entrain some air in concrete. Accelerating admixtures increase the rate of early strength development, reduce the time required for proper curing and protection, and speed up the start of finishing operations.
