Portland concrete suffers in service brittle failure, extensive crack propagation, and wear rates increasing with time. In spite of all the effort expended, these problems persisted when we had started our project. We used several polymeric fillers a

The isobaric thermal expansivity is an underestimated property. The entire composite structures disintegrate into pieces on heating – without the use of any mechanical force -when the constituents have significantly different expansivities. While o
