The compressive strengths of most ceramic products are seven to ten times greater than their respective tensile strengths. If ceramic structural members are kept in compression by prestressing, they are capable of carrying much larger loads than members with no prestressing. Through application of the principle of prestressing, tensile stresses are avoided. Results of preliminary experiments with prestressed ceramic members are described. The test findings indicate that prestressing gives marked improvement in resistance to failure in both static and impact loadings. Some possibilities are suggested for using prestressing methods with ceramic materials.
