“…Moreover, this composite concrete also exhibits great thermal and insulating characteristics [10]. There are other natural fibers have also been investigated (rice husks [11], hemp [12], or other fibers [13]). Mortar mixes, including these admixtures, impart excellent durability and are considered for coating applications or insulating.…”

This paper examines the ability to introduce an industrial waste product, wood chips, in concrete as a partial replacement for fine aggregate. Water was used to treat the wood chips before mixing to prevent them from soaking up the cement hydration water. The research presented in this paper aims to determine the impact of different treatment methods. The first method uses cement paste, and the second is sodium silicate. Twelve trial mixtures were prepared and cast employing water-cement ratios of 0.44 at various replacement levels of wood chippings. Fresh concrete properties tested inclusive slump test. Hardened concrete properties tested inclusively flexural strength, splitting tensile strength, compressive strength, and unit weight. Test results show that the lightening of concrete by wood shavings decreases the strength properties and the unit weight. On the other hand, the value of the slump test increased depending on the level of replacement of wood shaving. The most acceptable mixture and less reduction in the strength properties have been shown at MC10. The results of the tests demonstrate that the disposal of wood chips in concrete is practical and appropriate.

The article describes the results of pull-off adhesion strength of the FRCM-PBO (Fiber Reinforced Cementitious Matrix-p-Phenylene benzobis oxazole) composite adhered to the epoxy resin layer which is the connector with the timber beam. In addition, this paper shows the results of the tests of resistance to pull-off the epoxy resin layer from the pine beam. The tests were carried out based on the Polish Standard PN-EN 1542. The Pearson linear correlation analysis was also carried out in order to determine the correlation between the obtained results and the destructive forces. The factors that occurred during the test that may affect its results, such as the method of applying the bursting force, surface preparation of the tested elements and the types of substrate destruction, were also characterized. The experimental data show that in all the tested samples, non-initial adhesive destruction between the adhesive layer and the disc was observed.

“…The test results showed that the beams connected by screws and steel plates exhibited excellent structural performance. Fu et al [36] presented an innovative type of TCC deck using wood chip concrete, and wood chip concrete reduced the thermal conductivity by 30%. Du et al [37] investigated the shear behavior of inclined cross screws for TCC beams, and cross screws were suggested as an optimal arrangement for screws.…”

A novel bamboo-concrete composite structure with threaded reinforcement connections is presented. Experimental investigations on the shear behavior of the connectors and the flexural performance of the bamboo-concrete composite beams were carried out. The results indicate that the load-slip behavior of the shear connection with threaded reinforcement exhibits good ductility and that its failure mode is ductile failure. The threaded reinforcement provides an efficient connection before the initial shear failure. The load-displacement curves of the bamboo-concrete composite beams are close to those of the full composite structure, and the midspan displacement is greatly reduced under the same load compared with that of the contrast bamboo beams. The loads PL/250 and PL/300, corresponding to the midspan deflections of L/250 and L/300 ( L is the span of the beams) of the composite beams, increase by averages of 3.36 times and 3.71 times, respectively, compared to those of the contrast bamboo beams. The load-bearing performance of the beams in the service state is greatly improved. Based on the equivalent cross-sectional stiffness calculated using the γ-method with a reduction of 0.80, the calculated results of the displacement are in good agreement with the test results.
