Abstract Normal concrete sample (1) has a compressive strength of 222.22 kg/cm, normal concrete (2) has a compressive strength of 242.933 kg/cm, concrete using a mixture of ceramic 21% and red brick 7% sample (1) has a compressive strength of 177.911 kg/cm, concrete using a mixture of 21% Ceramics and red brick 7% sample (2) has a compressive strength of 189.777 kg/cm, concrete using a mixture of 10% Ceramics and red brick 4% sample (1) has a compressive strength of 204.667 kg/cm, concrete which uses a mixture of 10% Ceramics and red brick 4% sample (2) has a compressive strength of 137,333 kg/cm. It shows that the compressive strength of concrete decreases from increasing the volume of ceramics because the ceramic surface cannot bind perfectly. The highest K-204,667 with a mixture of 10% ceramics and 4% red brick and 28-day-old concrete, while to reach the K-250, is very far away. Of the 6 samples, the average reached K-195,807.

Ini menunjukkan bahwa Kuat tekan beton semakin berkurang dari bertambahnya volume keramik, karena permukaan keramik tidak bisa mengikat dengan sempurna. K- 204.667 tertinggi dengan campuran 10% keramik dan 4% bata merah serta beton berumur 28 hari, sedangkan untuk mencapai K-250 sangat jauh jauh. Dari 6 sampel tersebut rata-rata mencapai K-195.807.
