“…Affiliated scholars chose broken glass sources such as waste lamps or city glass and soda lime glass to partially replace natural sand or cement to study the thermophysical properties of green mortars. The results showed that adding waste glass powder to ordinary cement mortars could significantly affect their thermophysical properties [ 14 , 15 ]. Some studies found that mortars containing waste glass can be a viable filler material in radioactive waste disposal facilities [ 16 ].…”

Currently, most cities landfill most waste glass, resulting in the waste of resources and environmental pollution. Therefore, to realize the recycling of waste glass, solid waste glass was recycled and broken. Waste glass sand was prepared according to the gradation of natural river sand particles and the fineness modulus screening. It was used as an alternative material to natural river sand and mixed with mortar materials with different replacements. Analysis of the mortar with different replacements (0%, 20%, 40%, 60%, 80%) was conducted by combining macro and micro tests on the change law and influence mechanism of permeability, mechanical properties, and microstructure. The results showed that: the replacement of waste glass sand effectively improved the gas permeation resistance of mortar; with the increase of replacement, the gas permeation resistance of mortar roughly showed a trend of increasing first and then decreasing. The replacement of waste glass sand at 20% can better promote cement’s hydration so that the mortar’s porosity is reduced by 16.5%. The gas permeability decreases by 57.4%; the compressive strength increases by 3%, and the elastic modulus increases by 5.9%. When the replacement rate of glass sand is 20%, the test performance of mortar is the best among the five groups.

The use of iron waste in concrete is now of considerable importance, mainly because of the benefits for the environment and for improving the strength of concrete. The increased and unused of this industrial byproducts represents a challenge for the environment and human health. This article experimentally explores the influence of utilizing iron powder waste and iron fibers in concrete in order to enhance the thermophysical properties of concrete and reduce the environmental impact resulting from iron waste. The aim of this work is to study the thermophysical properties (thermal conductivity, volumetric heat capacity, thermal diffusivity and thermal effusivity) of concrete with waste iron powder and iron fibers for application in building construction. The iron powder waste was added to the concrete with different percentages of 0%, 5%, 15%, 20% and 25% respectively as a partial replacement of sand. The iron fibers were added with mix proportions including 1.0%, 1.5%, 2.0% and 2.5% by volume of concrete, and in two different arrangements, uniform and random. The thermal conductivity and the volumetric heat capacity of these samples were measured experimentally in the dry state at ambient temperature (20 °C), and at 28 days of age. The effect of the integration of iron powder and fiber on thermal properties was analysed.

“…The recycling of glass waste in construction materials has also been developed by several researchers [10][11][12][13][14][15]. The chemical composition of glass plays a very important role in the development of the pozzolanic reaction and the reduction in the rate of alkali-silica reactions, which subsequently influences the physical and mechanical properties of materials based on waste glass [16].…”

The aim of this study was to measure the thermophysical properties (thermal conductivity, volumetric thermal capacity, thermal diffusivity, and thermal effusivity) of red earth stabilized with cement and substituted with waste glass powder. Several samples (red earth) were stabilized with 6% and 12% cement and incorporated with different percentages of waste glass powder, which varied from 10% to 30%. The bulk density of the 12 samples was measured in the dry state and at room temperature. All samples were analyzed by a scanning electron microscope (SEM). The thermal conductivity and specific heat of the composite materials were measured experimentally with a thermal conductivity device (CT meter) in the dry state and at ambient temperature. The experimental results showed a decrease in the thermophysical parameters of stabilized red earth containing 12% cement and substituted by 30% glass powder. The following results were obtained: 53.97% for thermal conductivity, 45.42% for volumetric specific heat, 15.66% for thermal diffusivity, and 49.88% for thermal effusivity. The bulk density of the red earth also decreased by 13.66% in the dry state at ambient temperature. Stabilization with 6% and 12% cement played an important role in the compactness of the material and, consequently, improved its thermophysical performance. The composition of this new ternary material significantly affected the thermophysical properties of the red earth.
