Cenosphere Based No Aggregate Floating Concrete
Abstract: Concrete is an excellent building material, used widely around the world, but the only disadvantage of concrete is that it has self-weight. This self-weight does not allow concrete to be used in light-weight structures. In this work, mix design is prepared in such a manner that density of concrete is less than that of water and hence concrete can float on water and therefore it is termed as floating concrete. …

Digital Twin Assisted Intelligent Prediction of Polymer Composite Degradation Under Environmental Exposure
Abstract: Polymer matrix composites (PMCs) deployed in aerospace, marine, automotive, and renewable-energy structures are continuously subjected to coupled environmental stressors — ultraviolet (UV) radiation, moisture ingress, thermal cycling, and mechanical loading — that progressively degrade their mechanical performance. Conventional accelerated ageing tests and empirical lifetime models are time-consuming, destructive, and poorly suited to in-service, asset-specific degradation forecasting. This paper proposes a Digital Twin (DT) assisted intelligent prediction framework that fuses a …
