摘要： A method of cementing in a subterranean formation comprises: introducing a cement composition into a wellbore penetrating the subterranean formation, wherein at least a portion of the subterranean formation has a temperature less than or equal to the freezing point of an aqueous liquid, and wherein the cement composition comprises: (A) cement; (B) water; and (C) a pozzolan, wherein the cement composition has a heat of hydration of less than 50 BTU per pound; and causing or allowing the cement composition to set in the wellbore after the step of introducing. The pozzolan can have a calcium oxide concentration of less than 15% by weight of the pozzolan, and the pozzolan can have a concentration of at least 15% by weight of the cement. Gas hydrates can be present in or adjacent to a portion of the well.

摘要： A phosphate additive, such as apatite or monocalcium phosphate monohydrate, is used to treat concrete aggregate and concrete to improve its resistance to natural and salt induced breakdown. The phosphate can also be used in association with road salt to prevent spalling and breakdown of concrete surfaces and damages to cars. Used alone as a surface treatment, it has the same effect.

摘要： Compositions and methods relating to cementitious compositions are provided. The use of a blend of a rosin and a tannin to entrain air into cementitious compositions is provided. A blend of a rosin and a tannin in a weight ratio of 10:1 to 1:10 are added to a wet cementitious composition at levels of less than 1 % by weight based on the weight of the cement and air is mixed into the cement. The resulting cement will contain, e.g. 5 % to 10 % by volume air which improves the resistance of the set cement to freeze damage. Also provided is a method of entraining air into a cementitious composition which employs such a blend.

摘要： A method of treating earthenware bodies to enhance resistance to freezing and to assist the application of decals and the like thereto comprises treating the bodies with a liquid medium containing a water-repellant material such as silicone. In a subsequent drying step, the bulk of the liquid medium is removed while leaving the water-repellant material deposited in the pores of the earthenware body. In this way, subsequent entry of water and freezing and cracking is resisted. It has also been discovered that the treatment also enchances the ability of the earthenware surface to receive decals and the like without the need for glazing and an additional firing step.
