A study was undertaken to investigate the effects of crumb rubber on the strength and mechanical behaviour of Rubberized cement soil (RCS). In the present investigation, 26 groups of soil samples were prepared at five different percentages of crumb rubber content, four different percentages of cement content and two different finenesses of crumb rubber particle. Compressive strength tests were carried out at the curing age of 7 days, 14 days, 28 days and 90 days. The test results indicated that the inclusion of crumb rubber within cement soil leads to a decrease in the compressive strength and stiffness and improves the cement soil’s brittle behaviour to a more ductile one. A reduction of up to 31% in the compressive strength happened in the 20% crumb content group. The compressive strength increases with the increase in the cement content. And the enlargement of cement content is more efficient at low cement content.

Celem raportu jest przedstawienie wpływu granulowanych odpadów gumowych na wytrzymałość i mechaniczne zachowanie gumowanej mieszanki cementu i gruntu (Rubberized Cement Soil, RCS). W ostatnich dekadach wzrosło znaczenie obróbki gruntu z użyciem cementu w celu poprawy problematycznych gruntów. Kilku badaczy zmieszało różne wybrane dodatki z gruntami sztucznie cementowanymi. Ale warto zauważyć, że dodatki czasami prowadzą do wysokiej sztywności i kruchości. Ponadto problem związany z środowiskiem naturalnym jest coraz gorszy, a brak zasobów jest coraz bardziej dokuczliwy. Zastosowanie recyklingu opon gumowych w gruncie stabilizowanym cementem może być skutecznym sposobem wykorzystania gumy i rozwiązaniem problemu wysokiej sztywności i kruchości gruntów sztucznie cementowanych. Dodanie granulowanych odpadów gumowych powoduje znaczne zmniejszenie wytrzymałości oraz sztywności betonu.
