“…Although many investigations have been carried out on utilizing waste glass in the form of glass powder [7][8][9][10][11] and glass bead [12][13][14][15] in concrete products, it has not found its position in the construction industry yet. Expanded glass aggregates (EGA), is a new commercial product, which are manufactured from waste and post-consumer glass.…”

One of the growing concerns in the construction industry is energy consumption and energy efficiency in residential buildings. Moreover, management of non-degradable solid glass wastes is becoming a critical issue worldwide. Accordingly, incorporation of recycled expanded glass aggregates (EGA) as a substitution for natural fine aggregate in cement composites would be a sustainable solution in terms of energy consumption in the buildings and waste management. This experimental research aims to investigate the effects of EGA on fresh and hardened properties and thermal insulating performance of cement mortar. To enhance the mechanical properties and water resistance of the EGA-mortar, nano titanium dioxide (nTiO2) was used as nanofillers. The results showed an increase in workability and water absorption of the EGA-mortar. In addition, a significant decrease in bulk density and compressive strength observed by incorporating EGA into the cement mortar. The EGA-mortar exhibited a low heat transfer rate and excellent thermal insulation property. Furthermore, inclusion of nTiO2 increased compressive strength and water resistance of EGA-mortar, however, their heat transfer rate was increased. The results demonstrated that EGA-mortar can be integrated into the building envelop or non-load bearing elements such as wall partition as a thermal resistance to reduce the energy consumption in residential buildings.

Background: The management of marine waste is a major concern in several countries. Recycling shell waste in concrete formulations may be one of the alternatives for producing sustainable materials at a lower cost. Objective: In this research paper, the performance of ground mussel waste for non-structural concrete formulation has been investigated. Methods: Two alternatives were explored in this research. The first aimed at incorporating treated Mussel Powder (MP) for partial substitution of cement (6, 12, and 24% by weight). The second aimed to investigate the feasibility of using MP as an additive with a proportion of 3, 6, 9 and 12% by weight of cement. Physico-mechanical properties of advanced composites have been studied in both fresh and hardened state through several laboratory tests. Results: The test results indicated that the inclusion of the MP allowed the formulation of concretes with normal density and lower air content. The mechanical behavior was characterized using new formulas adapted to the newly formulated concretes. Based on the obtained results, the treated MP could be used as a cement substitute with a proportion up to 12% or as a mineral additive with a percentage of 3% to produce a non-structural concrete that meets the normative requirements in terms of compressive and tensile strength. Conclusion: The recycling of mussel waste in concrete will contribute to the preservation of the environment by reducing the quantity of shellfish waste. The concept of “green” concrete can be achieved through the use of the formulated concretes in the paving works or as a blinding concrete.

“…Hu et al [22] carried out transesterification of Chinese tallow oil for biodiesel synthesis using freshwater mussel shell derived catalyst and reused it more than seven times without serious deactivation. Ez-zaki and co-worker [23] have shown the manufacturing of eco-friendly building material mortar from waste mussel shell and glass by partially replacing the sand. It is reported that incorporation of these waste materials improved the mortar in terms of thermal insulation, compressive strength, and resistance against chloride attack.…”

Considering the combination of the good physical-mechanical property of mussel shell (MS) and its bulk availability at low processing cost, in present work an attempt has been made to use it as reinforcing particulate material for fabricating Al6061/MS composite through stir casting route. The composite is fabricated with 2, 4, 6, 8 and 10 weight percent (wt%) of mussel shell reinforcement. Microstructural characterization revealed the fair distribution of particles in the matrix. Fabricated matrix with 6 wt% mussel shell has shown the maximum hardness and wear resistance beyond that adverse effect has been quantified. Linear regression analysis helped in establishing the relationship between independent variables of load, sliding distance and reinforcement volume in wt% to calculate wear loss and wear rate. Analysis of variance helped to confirmed that incorporation of MS particulates significantly contributing to the improvement of the wear properties.
