Containers incorporating a hydraulically settable structural matric including a hydraulically settable binder such as cement for use in storing, dispensing, and/or packaging of food and beverage products are disclosed. The disposable and nondisposable food and beverage articles of manufacture have high tensil, compressive, and flexural strength, and are lightweight, insulative (if desired), inexpensive, and more environmentally compatible than those currently used. These disposable containers and cups are particularly useful for dispensing hot and cold food and beverages in the fast food restaurant environment. The structural matrix of the food and beverage containers includes a hydraulic cement paste (formed from the reaction of water with, e.g., a portland-type cement) preferably in combination with a phenology-modifying plasticizer, such as methylhydroxylthylcellulose, various aggregate materials and fibrous materials which provide desired properties at a cost which is economical
