“…However, by placing more percentage of crushed plastic the resistances decrease, and they are even lower than the compressive effort obtained when testing the blocks without plastic. According to Tian et al [42], by adding recycled materials to the concrete mixture, its resistance is reduced to compression, which is even less than the designed resistance due to the presence of low-quality aggregates. The greatest resistance was encountered in the blocks that contain a percentage between 10% to 30% of crushed PET plastic (Fig.…”

The current study describes the development and evaluation of hollow concrete blocks using recycled polymers and a waterproof, resistance improver nanoadditive together with cement, sand, and pumice to search for an ecological building material capable of reducing the environmental pollution. Three phases were performed; in which the first, we characterized petrous aggregates, polyethylene terephthalate (PET) and the nanoadditive. In the second one, several dosages were established with different percentages of crushed PET that represented to the sand. Additionally, a nanoadditive's part was placed in relation to the total water of the mixture. In the third phase, the compressive stress, volumetric weight, and absorption of the elaborated specimens were determined according to the national standard. The resulting optimal dosage was about 25% PET in replacement of sand + 0.0087 kg of nanoadditive, able to generate a better quality material, obtaining a compressive strength of 36.5 kg/cm 2, very close to the normative (40 kg/cm 2 ) and superior to the of commercial blocks (14.35 kg/cm 2 ). Regarding the volumetric weights, the plastic had a good performance as it managed to reduce the weight by 20%, while the use of the nanoadditive waterproofing decreased by 25% of water absorption. The block of the current research was twice as expensive as the traditional, even if production is tripled, as it was reduced to only $ 0.06 (8%). However, in comparison with the industrially elaborated procedure, the costs are very similar.

“…Su et al (2015) have shown that the particle size distribution of fine rubber aggregate slightly affects RBC mixtures' compressive and tensile strengths. Tian et al (2020) concluded that using 30% rubber particles as partial replacement of natural aggregates in self-compacting concrete reduces its compressive strength by 46.1% and its static modulus of elasticity by 31%. Noaman et al (2016) have reported that as the ratio of rubber aggregates in concrete increases, the absorption energy of concrete represented by the area under the stress-strain relation is improving.…”

PurposeCurrently, many experimental studies on the properties and behavior of rubberized concrete are available in the literature. These findings have motivated scholars to propose models for estimating some properties of rubberized concrete using traditional and advanced techniques. However, with the advancement of computational techniques and new estimation models, selecting a model that best estimates concrete's property is becoming challenging.Design/methodology/approachIn this study, over 1,000 different experimental findings were obtained from the literature and used to investigate the capabilities of ten different machine learning algorithms in modeling the hardened density, compressive, splitting tensile, and flexural strengths, static and dynamic moduli, and damping ratio of rubberized concrete through adopting three different prediction approaches with respect to the inputs of the model.FindingsIn general, the study's findings have shown that XGBoosting and FFBP models result in the best performances compared to other techniques.Originality/valuePrevious studies have focused on the compressive strength of rubberized concrete as the main parameter to be estimated and rarely went into other characteristics of the material. In this study, the capabilities of different machine learning algorithms in predicting the properties of rubberized concrete were investigated and compared. Additionally, most of the studies adopted the direct estimation approach in which the concrete constituent materials are used as inputs to the prediction model. In contrast, this study evaluates three different prediction approaches based on the input parameters used, referred to as direct, generalized, and nondestructive methods.

“…The definition of recycled wood, as stated in the Waste Framework Directive (2008/98/EC), includes a variety of residual and old wood, such as wastes from construction, furniture, etc., and packaging [3][4][5]. Both wood-based panel industries and pulp and paper facilities produce, annually, a substantial amount of by products, namely solid waste and nonhazardous sludge which require utilization as by-products or as waste materials [6,7].…”

The development of alternative wood composites based on the use of waste or recycled materials can be beneficial due to over exploitation of natural resources. Under this frame, an option for the successful utilization of waste polystyrene which avoids environmental problems that formaldehyde adhesives cause and also reduces waste disposal, is its potential application as a binder for the production of value-added environmentally friendly and low cost wood composites. Two types of panel were successfully made, consisting of wood dust and two recycled polystyrene contents, namely, 15% and 30%. Both physical properties, water absorption and thickness swelling, and mechanical properties, modulus of rupture, shear strength parallel in the plane of the board and glue line shear strength, were significantly improved as the recycled polystyrene content increased from 15% to 30%. Water absorption and thickness swelling after 24 h immersion in water were improved by 165% and 750% as the recycled polystyrene content increased from 15% to 30%. The magnitude of the improvement in mechanical properties however, was less pronounced than of the physical properties since modulus of rupture, shear strength parallel in the plane of the board and glue line shear strength were increased by 43.6%, 50% and 61.5%, respectively. The low viscosity of the recycled polystyrene caused more mobility inside the panel matrix and therefore, an improved penetration took place into adequate depth of the compressed dust particles. It is concluded that boards can be successfully produced using these waste raw materials, wood dust and recycled polystyrene in organic solvent as a binder, and therefore it can reduce waste disposal and provide cleaner production for the development of wood-based boards.
