The use of plastic is increasing day by day, although steps were taken to reduce its consumption. This creates substantial garbage every day which is much unhealthy. A healthy and sustainable reuse of plastics offers a host of advantages. The suitability of recycled plastics as coarse aggregate in concrete and its advantages are discussed here. The initial questions arising of the bond strength...

By increasing the demolition of old concrete structures and the interest of civil industries to consume cheaper materials, using Recycled Concrete Aggregate (RCA) can cause environmental protection and decrease the construction costs. On the other hand, the high potential of Recycled Aggregate Concrete (RAC) in concrete industry was established by extensive experimental researches were performe...

Concrete is a form of construction in the composite material consisting mixture fine aggregate, coarse cement, and water. However, certain cases, concrete application often problem, especially lack minimal amount aggregate material, increasing prices. Recycled (RCA) an embodiment composed recycled materials. obtained from fragments or remnants demolition unused concrete. The method used to make...

This study discusses the torsional capacity of recycled coarse aggregate (RCA) reinforced concrete beams under pure torsion based on experimental findings available in literature. The data RCA specimens were collected and compared with conventional key variables, such as compressive strength longitudinal transverse reinforcement ratios, those variables affect beams. Overall, database consisted ...

the current research intends to study the possibility of producing fiber recycled self-compacting concrete (frscc) using demolitions as a coarse aggregate (crushed red brick and crushed ceramic). steel fibers were used in recycled self-compacting concrete (rscc) to improve fresh and hardened properties of this type of concrete. thirty nine concrete mixes were prepared to achieve the aim propose...

This study introduces, two models based on Gene Expression Programming (GEP) to predict compressive strength of high strength concrete (HSC). Composition of HSC was assumed simplified, as a mixture of six components (cement, silica fume, super-plastisizer, water, fine aggregate and coarse aggregate). The 28-day compressive strength value was considered the target of the prediction.  Data on 159...
