Monitoring of Moisture and Dimensional Behaviors of Nail-Laminated Timber (NLT)-Concrete Slab Exposed to Outdoor Air

The moisture and dimensional behaviors of a nail-laminated timber (NLT)–concrete slab composed an NLT–plywood composite topping concrete are monitored for 385 days. is developed using as flexural elements such floors. humidity control wood gently introduces significant fluctuations under the ambient relative into slab, in result changes. equilibrium content increases from 6.7% to 15.3% during monitoring period, resulting width (radial) strain 0.58%. length (longitudinal) negligible, height (tangential) excluded analysis because abstruse signal patterns generated. Concrete pouring causes permanent increase composite. However, deforms weight mixture loosens structure, not amount mixture. stabilization effect system demonstrated lower than total lumber plywood, which constituting structure.
