Abstract: The using of waste products as a recycled material was one of the most important studies for saving money and reduces the pollution. Mortar and concrete mixes with (10, 20 and 30) % of brick, glass and tile powder as replacement by weight of cement was investigated. The concrete mixes using brick or glass as 10 %replacement of cement exhibited enhancement in compressive strength about (6, 4.7 and 2.0) % and (7.2, 5.6 and 2) % at age 7, 28 and 90 days respectively compared to reference mix. The 20 % replacement of glass powder also showed an increase in the compressive strength up to (8, 6.3 and 4) %at age 7, 28 and 90 days respectively compared to reference mix. Finally concrete mix using (10, 20 and 30) % tile powder as replacement of cement showed a reduction in the compressive and flexural strength with less density with age.
