| Descripción: | An experimental investigation was carried out to study the effect of volcanic tuff (V.T.), as a fine aggregate on the flexural and shear capacities of reinforced concrete beams. Three different types of volcanic tuff which is a local material that is available at different locations in Jordan (known as yellow, gray and brown volcanic tuff) were used in this study. Four grades of concrete compressive strengths (20, 30, 40 and 50 MPa) are also used. The experimental program consisted of testing 64 beams (16 beams with 0% of volcanic tuff and 16 beams with 20% volcanic tuff as a fine aggregate for each type of volcanic tuff). The analysis showed that replacing the fine aggregate by 20% volcanic tuff will improve the flexural and shear capacities of the reinforced concrete beams by 6% to 16% for brown tuff, 3% to 8% for gray tuff and 10 % to 26 % for yellow tuff for the four concrete strength grades.Key Words: Pozzolan (Volcanic tuff), flexural and shear capacities, Reinforced concrete beams |
