Abstract
The use of supplementary cementitious materials (SCMs) has increased over the years due to the carbon footprint associated with the production of cement, which contributes to 10% of the total global CO2 gas emissions. This causes an increase in global warming, and the exponential increase in demand for construction of concrete has caused depletion of natural resources.. Therefore, it has become necessary to reduce the CO2 emissions by reducing our dependency on cement as a binder and developing eco-friendly concrete using alternative binders from agro-industrial waste materials. This study utilizes Rice Husk Ash (RHA) as replacement of OPC .The cement content is replaced with 5%, 10%, 15%and 20% and Also Utilization of waste tyre as a material to improve elastic properties in rigid pavement construction in compost environment has not investigated yet. The rigid pavement in compost environment needs to be impermeable and posses high elastic properties. This thesis presents mechanical properties and workability of concrete incorporating crumb rubber as replacement in two different sizes in concrete mixture with a percentage of 10, 20, and 30 by fine aggregates and coarse aggregate. Replacement of natural aggregate with waste tyre rubber can have an undesirable influence on the mechanical properties of self-compacting concrete, i.e., compressive strength, flexural strength, splitting tensile strength, and modulus of elasticity, however. On the other hand, replacing natural aggregates (eg: FACA) with waste tyre rubber can improve impact resistance, ductility, resistance to cracking effect and fatigue resistance.
