“…High-quality and durable concrete is required to reduce the rapid deterioration of concrete structures in severe conditions. The decline of concrete durability is affected by factors such as carbonation, alkali-silica reaction, sulphate attack, freeze-thaw attack, and chloride penetration [ 11 ]. All of them are directly or indirectly related to the permeability of the concrete.…”

The large increase in the world population has resulted in a very large amount of construction waste, as well as a large amount of waste glycerol from transesterification reactions of acyl glycerides from oils and fats, in particular from the production of biodiesel. Only a limited percentage of these two residues are recycled, which generates a large management problem worldwide. For that reason, in this study, we used crude glycerol as a carbon source to cultivate polyhydroxyalkanoates (PHA)-producing mixed microbial cultures (MMC). Two bioproducts derived from these cultures were applied on the surface of concrete with recycled aggregate to create a protective layer. To evaluate the effect of the treatments, tests of water absorption by capillarity and under low pressure with Karsten tubes were performed. Furthermore, SEM-EDS analysis showed the physical barrier caused by biotreatments that produced a reduction on capillarity water absorption of up to 20% and improved the impermeability of recycled concrete against the penetration of water under pressure up to 2.7 times relative to the reference. Therefore, this bioproduct shown to be a promising treatment to protect against penetration of water to concrete surfaces increasing its durability and useful life.

“…Paver blocks made with plastic waste can easily used for light weight traffic or non traffic road. Sandra et al (2020) [12] determined the corrosion behavior of the copper slag of steel bars in reinforced concrete column. They made a reinforcement concrete column having cross section of 300mmx300mm with 1500mm height.…”

This research illustrated the variations in strength by substituting copper slag and fly ash to the paver block and it was treated under the curing regime that is normal curing, immersion curing and gunny bag curing. Zig-zag shape paver blocks were constructed for this research. 35% of copper slag was substituted with sand and 25% fly ash with cement. Abrasion test, water absorption test, compression test, flexural test and split-tensile test were carried out to compare the strengths in between both the mixes such as conventional mix and substitution mix. In comparison the values of all the test performed depicts the more strength was acquired by substitutional mix.

“…Quality characteristics of fine aggregate used as concrete structural components play an important role in determining the quality characteristics of concrete structures produced because fine aggregates fill most of the concrete volume. Sea sand as one type of fine aggregate material has availability in large quantities [10].…”

Concrete is a composite building material made from a combination of aggregate and cement. The limitation of concrete material, in this case, is a fine aggregate (river sand). The utilization of sea sand as an alternative to fine aggregate in the manufacture of concrete is motivated by the availability of sea sand in nature in very large quantities. This study aims to determine the comparison and how much the compressive strength of concrete produced when using sea sand. The test was carried out when the specimens were 7, 14, and 28 days old with the specimens used in this study were concrete cylinders with a diameter of 15 cm and a height of 30 cm. The results showed that the use of sea sand as a substitute for fine aggregate showed an average compressive strength in 7 days of 18.86 MPa, an average compressive strength of 14 days of 25.52 MPa, an average compressive strength of 28 days of 29.00 MPa. Then for the average compressive strength value of the use of river sand in 7 days is 17.17 MPa, the average compressive strength of 14 days is 23.24 MPa, the average compressive strength of 28 days is 26.41 MPa.
