Utilization of Clinker Brick Used for No-Fines Concrete

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