The relationship between the unit weight of the concrete, HDPE ASTM C29 [34] uses the term unit weight to refer to the concrete property in mass Recycling 2021, 6, x FOR PEER REVIEW 10 of 21 per unit volume. This gives a good indication of sample concrete density. The unit weight 3.2.

This gives a good indication of sample concrete density. The unit weight addition of HDPE lamellar particles led to lighter concrete due to the low density of for all samples was determined by comparing the specimen’s weight with the specimen’s HDPE plastic, which was applied to B0, f’c10, and f’c25. However, the size of the HDPE substantial volume. The relationship between the unit weight of the concrete, HDPE la- mellar content, and its sizes are given in Figure 6. The graphs show that a greater addition sheets did not affect the concrete unit weight, as they all showed a similar value for of HDPE lamellar particles led to lighter concrete due to the low density of HDPE plastic, certain percentages.
