ABSTRACT:
Rubber crumb reinforced cement-concrete structures provide resistance to cracking, improve shock wave absorption, lower heat conductivity and improve the acoustical environment. The structures are comprised of cement-like materials having a predetermined proportion (from about 1% to about 30% by weight of cement) of recycled scrap rubber crumbs undirectionally aligned in the cross section of said structures.
