“…The material under water-saturated surface conditions of specific gravity can be interpreted as the ratio between the weights of the saturated material with the total volume of material [25]. In contrast, the material's specific gravity under oven-dry conditions is the ratio between the weights of dry material due to drying with the oven and the total material volume [26]. Water absorption is the ability of a material to absorb water.…”

Clinker bricks go into excessive temperatures during the process, are waste in brick making, and tend to be unusable, but it can be used as an alternative material to coarse aggregate in concrete mixtures. This research is about clinker brick waste which is used as coarse aggregate in no-fines concrete with a water-cement ratio is 0.45 with a volume ratio of 1:3 for 4 sample variations at different concrete ages where a mixture of four variations 0%, 25%, 50%, and 100% will be tested at concrete age 7 days, 14 days, 28 days. The results have shown that the greatest concrete compressive strength at age 7 days, 25% mix is 19.22 MPa, and the lowest 50% mix is 13.99 MPa. For 14 days, the greatest compressive strength at variation 1 without clinker bricks (0%) compressive strength 16.78 MPa, and that the lowest at variation 3 with 50% at 11.71 MPa. For 28 days, concrete ages are the normal age commonly used, the most significant concrete compressive strength at 25% mix with compressive strength of 6.59 MPa and the lowest at 50% mix 10.27 MPa. The best compressive strength at 25% mix variation 2 with compressive strength of 16.59 MPa but still smaller than the reference design f'c â‰¤20 Mpa. Based on the weight of No-fine Concrete 70% lighter, that concrete without fines using clinker bricks, although lighter, cannot be for structural concrete because compressive strength tends to decrease, but it can still be for nonstructural concrete.
