Summary: Conventional aggregates place considerable strain on natural resources, prompting the need for sustainable alternatives. One such solution is Rubber Tire Crumb-Based Cement Mortar (RTCCM), which incorporates recycled rubber tire crumbs (RTC) as a partial sand replacement. This approach not only reduces reliance on finite raw materials but also addresses the environmental challenge of managing discarded tires, aligning with the principles of the circular economy. This study, utilizing RTC provided by Vermillion Ventures Inc. in Muntinlupa, aims to evaluate the physical and mechanical properties of RTCCM, including material characterization, density, water absorption, compressive strength, and flexural strength. Additional properties, such as sound absorption and thermal conductivity, were also assessed. Best suitable mix proportions of rubber content (RC) were determined, with samples prepared and cured in North Caloocan City following ASTM standards. Fine aggregates adhered to AASHTO sand classifications, passing sieve No. 10 (2mm) and retained on sieve No. 200 (0.075mm). Laboratory results revealed that increased RTC content raised water absorption levels while compressive and flexural strength decreased linearly. RTCCM exhibited enhanced sound absorption capabilities with higher RTC percentages. In terms of thermal performance, RTCCM demonstrated better thermal insulation than conventional mortar, although increased RTC content resulted in slightly higher thermal conductivity. The study found that RTCCM with 20% RC offered the best suitable balance of performance, meeting standard compressive and flexural strength requirements while maintaining competitive water absorption, sound absorption, and thermal insulation properties. This innovative material demonstrates significant potential for sustainable construction applications by reducing waste and minimizing environmental impacts.

Conventional aggregates place considerable strain on natural resources, prompting
the need for sustainable alternatives. One such solution is Rubber Tire Crumb-Based
Cement Mortar (RTCCM), which incorporates recycled rubber tire crumbs (RTC) as a
partial sand replacement. This approach not only reduces reliance on finite raw materials
but also addresses the environmental challenge of managing discarded tires, aligning with
the principles of the circular economy. This study, utilizing RTC provided by Vermillion
Ventures Inc. in Muntinlupa, aims to evaluate the physical and mechanical properties of
RTCCM, including material characterization, density, water absorption, compressive
strength, and flexural strength. Additional properties, such as sound absorption and thermal
conductivity, were also assessed. Best suitable mix proportions of rubber content (RC)
were determined, with samples prepared and cured in North Caloocan City following
ASTM standards. Fine aggregates adhered to AASHTO sand classifications, passing sieve
No. 10 (2mm) and retained on sieve No. 200 (0.075mm). Laboratory results revealed that
increased RTC content raised water absorption levels while compressive and flexural
strength decreased linearly. RTCCM exhibited enhanced sound absorption capabilities
with higher RTC percentages. In terms of thermal performance, RTCCM demonstrated
better thermal insulation than conventional mortar, although increased RTC content
resulted in slightly higher thermal conductivity. The study found that RTCCM with 20%
RC offered the best suitable balance of performance, meeting standard compressive and
flexural strength requirements while maintaining competitive water absorption, sound
absorption, and thermal insulation properties. This innovative material demonstrates
significant potential for sustainable construction applications by reducing waste and
minimizing environmental impacts.
