HOMOGENEOUS COMPOSITION OF CEMENTITIOUS AND TAR COMPONENTS AND PROCESS FOR FORMING SHAPED ARTICLES THEREFROM |
摘要 |
Improved cementitious compositions having increased flexural, tensile and shear-bond strength, increased wear resistance, decreased water permeability and enhanced workability than previous cement compositions, which are prepared with water treated with an emulsified tar component, and preferably a residual amount of sodium tripolyphosphate, are provided.
