grout [grau̇t] (materials) A fluid mixture of cement and water, or a mixture of cement, sand, and water. Waste material of all sizes obtained in quarrying stone. Grout A binding or structural agent used in construction and engineering applications. Grout is typically a mixture of hydraulic cement and water, with or without fine aggregate; however, chemical grouts are also produced. See Cement The type most commonly specified in construction and engineering is cementitious grout, which is used where its more conventional sister material, concrete, is less suited because of placing limitations or restrictions on coarse-aggregate contents. Cementitious grouts are used to fill voids and cracks in pavements, building and dam foundations, and brick and concrete masonry wall assemblies; to construct floor toppings or provide flooring underlayment; to place ceramic tile; and to bind preplaced-aggregate concrete. See Concrete Grout can be formulated from a variety of cements and minerals and proportioned for specific applications. Neat cement grout refers to formulations without aggregate, containing only hydraulic cement, water, and possibly admixtures. Sanded grout is any mix containing fine aggregate and it is formulated much like masonry mortar. Whether neat or sanded, cementitious grouts derive their strength and other properties from the same calcium silicate-based binding chemistry as concrete. How to thank TFD for its existence?

| The epitaph of Sir Jenkin Grout is not wholly unintelligible to the present age: "Here lies Sir Jenkin Grout, who loved his friend and persuaded his enemy: what his mouth ate, his hand paid for: what his servants robbed, he restored: if a woman gave him pleasure, he supported her in pain: he never forgot his children; and whoso touched his finger, drew after it his whole body. There was not one straight floor from the foundation to the roof; the ceilings were so fantastically clouded by smoke and dust, that old women might have told fortunes in them better than in grouts of tea; the dead-cold hearths showed no traces of having ever been warmed but in heaps of soot that had tumbled down the chimneys, and eddied about in little dusky whirlwinds when the doors were opened. |
