Abstract
Normally crystalline vinylidene chloride polymer latex-modified portland cement compositions having exceptionally high elastic modulus by the incorporation therein of from about 1.5 to about 3 percent of composition volume of a fibrous mixture consisting of (a) a nylon fiber and (b) a steel fiber wherein the fibrous materials are present in the mixture in amounts representing a ratio of (a) to (b) of about 1:2 to 2:1 based on mixture volume; which compositions are particularly suited for use in construction in preparing or repairing structures such as pavement and the like requiring high energy absorption properties.
