The potential for using fly ash as a supplementary cementing material in concrete has been known almost since the beginning of the previous century. Fly ash was used as a supplementary cementing material (SCM) in the production of Portland cement concrete. A supplementary cementing material, when used in conjunction with Portland cement, contributes to the properties of the hardened concrete through hydraulic or pozzolanic activity, or both. In this study, the fly ash and waste glass powder were used in concrete blocks to study the improvement of concrete in terms of workability and strength. Therefore, an experimental study will be conducted to measure the engineering properties of cured concrete. In this research, local raw material from Jaresh area was used.
In recent decades, research has demonstrated that high dosage levels of fly ash (40% to 60%) can be used in structural application producing concrete with good mechanical properties and durability (Marceau 2002) [

 10% of cement ratio of (fly ash/waste glass powder)
 20% of cement ratio of (fly ash/waste glass powder)
2) Cylinder concrete specimen three samples):

 10% of cement ratio of (fly ash/waste glass powder)
 20% of cement ratio of (fly ash/waste glass powder)
According to ASTM (211.181) and NEVILL, we chose specific compressive strength 25 MPA with a slump 50 mm and weight coarse aggregate 1600 kg/m^{3}, with maximum w/c ratio 0.5 and water content 180 kg/m^{3} and approximate entrapped air content per cent 1.5%.

・ Adding 20% of fly ash of concrete cube result in reduction of compressive strength at age 7 days by 69%, so that it can be ststed that adding 20% of fly ash gave a remarkable decrease of compressive stregnth of concrete.whereas adding 20% of waste glass to the concrete mixure resluted in decreasing of compresssive strength by 33%. The standard error for all samples at age 7 days range between 0.02  0.088, which indicated of the accurancy of the average value of compressive strength.
・ At age 28 days the average compressive strength of concrete cube specimen were increased 31% by adding 10% of fly ash, so that this ratio of additive material is preferable to increase concrete strength. However, no remarkable increase of compressive strength by adding 10% of waste glass.
・ Adding 20% of fly ash result in decreasing of compressive strength of con crete cube at age 28 days by 49%, so that this ratio of additive material is not preferable and gave significant reduction of compressive stregnth of concrete. Whereas 20% of waste glass resulted in decrease of compressive stregnth by 33%.
・ For cylinderical concrete samples, the average compressive strength at age 7 days was increased by 27% by adding 10% of fly ash, so that 10% of fly ash was preferable ratio to achive a desire compressive strength. On the other hand, slight increase of compressive strength was observed when 10% of waste glass was added.
