The fundamental physical and mechanical properties of the stones, including their density, water absorption capacity, compressive strength, and elastic modulus, were evaluated by the writers through laboratory tests.
The study assessed the mechanical and physical properties, such as porosity and water absorption, before and after exposure to simulated climate conditions.
The study investigated how salt contamination affected the physical properties of the stones, such as compressive strength and water absorption capacity.
The authors evaluate the thermal conductivity, water absorption capacity, and compressive strength, of the bricks to assess their suitability for use in building construction to reduce environmental impacts and achieve sustainable development goals.
Overall, it provided valuable insights for researchers and professionals involved in historic building retrofitting and energy efficiency assessments[16].

The basic performance of products and the accessory performance shall meet the requirements of the current relevant national or professional standards.
Water consumption is divided into two types, one is nominal water consumption which refers to the nominal volume of water used by the product, and the other is the actual water consumption which refers to the measured average water consumption by the product.
In this paper, water consumption refers to the nominal water consumption.
Water shortage and water pollution are worldwide environment problems, and the water crisis has severely restricted human sustainable development.
Fresh water consumption refers to the amount of water from various water sources that the enterprise needs in the production of unit product.

Approximately 40% of planned low-emission hydrogen projects are in water-stressed regions, prompting developers to explore desalination and wastewater recycling to ensure a sufficient water supply [1,3].
Green hydrogen is produced solely through water electrolysis, which splits water molecules into hydrogen and oxygen using electricity from a renewable energy source.
Figure 6 presents the cost trends of alkaline water electrolyzers in Europe.

As highly porous material it can absorb water and release it slowly into the soil.
Gas formation can be achieved via expulsion of hydration water from clay minerals or via decomposition or reduction of inorganic salts and oxides.
Granules were shaped by adding a controlled amount of water in order to achieve the consistency needed for shaping.

., (Tianjin, China). 2.2 Fabrication of microPCMs/epoxy composites The encapsulation was carried out in a 500 ml three-neck round-bottomed flask. 3.0 g SMA and 0.8 g NaOH were dissolved in 100 ml water (50 °C).
Then dropped the emulsion in the bottle dipped in steady temperature flume and stirred at a speed of 1500 r·min-1, and dropped 25 g mixture of prepolymer (12.8 g) and deionized water at a rate of 0.25 g·min-1.
The resultant microcapsules were filtered and washed with water and dried in a vacuum oven.
The method to evaluate the encapsulated ratio (E) is by Eq.1, (1) Where is the calculated heat fusion of microPCMs by DSC, the latent heat of fusion of PCM, is the total weight of PCM in emulsion. is the value of microPC- Ms, calculated through the integral of the curves area by software Origin 8.0 Professional. 2.5 TGA measurement Ten micrograms of the dried microPCMs sample was tested with a heating rate of 5 °C·min-1 and nitrogen (N2) as the purging and protective gas.
