“…On the other side, cement and construction composites have great interest due to the different applications and benefits they provide. One of the recycling methods is the use of polymer waste, solid byproducts, natural waste, and bricks in construction materials, such as composite blocks and lightweight partitions, to share with the waste management. − Several features, such as lightweight, high strength and elasticity, easy processing, corrosion resistance, low cost, and weathering resistance, make them alternatives to commercial aggregates in modern building and low-density construction applications. − Composites are included in different forms and types due to the durability and improved properties, such as reinforced concrete, reinforced plastic, cement, polymer–cement composite, fiber–cement composite, and fiber–polymer composite. , The global consumption of plastic in the building and construction markets is expected to be duplicated in 2027 with more intense studies. The influence of adding waste powders of concrete bricks and recycled polyethylene terephthalate on mortar was studied in novel improved construction composites.…”

The hazards of polymer waste and emitted gas on the environment pose a global challenge. As a trial to control this, the current work aims to reuse the polymer waste mix (PM) as fillers in calcium silicate to prepare new composites of environmentally friendly polymer concrete. PM was first subjected to treatment to obtain treated PM (TPM) and then was filled in new dicalcium silicate cement with different concentrations. The microstructural characterizations declare the successful preparation of the dicalcium silicate base material. After the curing reaction, the precipitated carbonate main product is responsible for the gained properties. The CO 2 uptake% in the proposed composites reached 16.6%, referring to the successful storage of CO 2 gas during curing. The treatment reaction led to an increase in the flexural and compression strengths due to the strengthening of the polymer waste mix−cement interface; the strengths were increased gradually with more contents of TPM fillers. 7% TPM−cement concentration achieved the highest flexural strength and compression strength of10.2 and 12.7%, respectively, compared with blank cement. The used polymer improved slightly the pull-off force of the prepared cement, and 7 and 5% TPM−cement composites have the maximum values. All the proposed composites passed the impact testing without failure, where the combination between the polymer waste and silicate cement resulted in a stable composite surface. Compared with the blank, the different concentrations of TPM−cement composites show more stability against water absorption. In addition, the proposed composites and blank cement have a very low carbon dioxide emission. The ability to recycle the polymer waste, form new type of low-energy silicate, improve the mechanical and surface properties, uptake CO 2 gas, and reduce gas emission makes the proposed polymer waste mix−cement composites as environmentally friendly construction products.

Integrating phase change materials (PCMs), which store thermal energy as latent heat, into renewable energy production is an efficient way to harness solar energy. Thereby, the aim of this work is to develop convenient and efficient method to prepare a bio‐composite phase change materials (BCPCMs) that are eco‐friendly and cheap. The polyethylene glycol (PEG) with large latent heat was used as PCM, eggshell powder (ES) as an energy storage material (bio‐energy resources/bio‐waste is converted into useful energy storage material), the low‐density polyethylene (PE) performed as the supporting material and powder graphite (G) was the additives for improving the thermal conductivity. According to thermal gravimetric analysis (TGA), the use of ES and G improved the thermal stability of BCPCM. On the other hand, the results of the differential calorimetric analysis (DSC) showed that BCPCM6 with the addition of 5 wt% of graphite filler in the mixture PEG/PE/ES (70/20/5 wt%) provides excellent thermal stability and high energy storage density per unit mass. In light of its high latent heat storage capacity of 120.1 J/g as well as its ability to prevent PEG exudation, BCPCM ensures higher thermal conductivity and shape stability during phase transition than ordinary PCM. Significant enhancement in melting‐solidification time shows an improvement in Thermal Energy Storage (TES) response time to the demand by adding ES and G respectively to the PCM. Based on the obtained results, the BCPCM as a potential candidate for an application in buildings of hot and dry climates.Highlights Shape‐stabilized BCPCMs were prepared by blending and impregnating method. The BCPCM combines a high storage capacity and high heat propagation rate. BCPCM6 provides excellent thermal stability and high energy storage density. Enhancement in melting‐solidification time by adding ES and G to the PCM. BCPCM as a candidate for an application in buildings of hot and dry climates.
