Outdoor applications of wood-plastic composites (WPCs) have raised question about the durability of such materials. WPCs are vulnerable to weathering factors such as UV radiation, moisture and freeze-thaw action. Weathering can cause discoloration, chalking, dimensional changes and loss of mechanical properties.This comparative study examines the effects of increased moisture content and artificial weathering on the properties of wood-plastic composites. Five commercial wood-plastic composite products from five different manufacturers were chosen and their water absorption, thickness swelling, impact strength and resistance to artificial weathering analyzed. An in-house manufactured wood-polypropylene composite with carbon black pigment was used as a reference product. In addition to quantitative investigation of material properties, the measured values were also compared with the values ​​reported by the manufacturers.The composite samples were exposed to accelerated weathering in a xenon weathering chamber for 500 hours. The color change was estimated by spectrophotometer method. The weathering resulted in no significant color fading of the composites. After weathering, the general trend was a minor decrease in impact strength. Also the water absorption and thickness swelling of commercial WPC products remained on a low level.

This work reports on the incorporation of Flint and Kaolin rocks powders in the cement mortar in an attempt to improve its mechanical properties and produce an eco-friendly mortar. Flint and Kaolin powders are prepared by dry mechanical milling. The two powders are added separately to the mortars substituting cement partially. The two powders are found to improve the mechanical properties of the mortars. Hardness and compressive strength are found to increase with the increase of powders constituents in the cement mortars. In addition, the two powders affect water absorption and thermal conductivity of the mortar specimens which are desirable for construction applications. Kaolin is found to have a greater effect on the mechanical properties, water absorption, and thermal conductivity of the mortars than Flint. This behavior is discussed and analyzed based on the compositional and structural properties of the rocks powders.

CT technology was used in nondestructive testing procedure of Wood-plastic composite in the paper as well as computes the CT number range of different Wood-plastic composite tomography slices in statistic method. A fitting mathematical model between CT number and Wood-plastic composite density was Calculated, because of the linear relationship exists between Wood-plastic composite density and CT number. Hence, a new method in the nondestructive testing of Wood-plastic composite density was provided.
