    Abstract:

    To study the influence of added waste glass fine aggregate on the performance of concrete column, compression static loading test was carried out on 6 reinforced normal aggregate concrete columns and 12 reinforced recycled glass fine aggregate concrete columns. Considering the replacement rate of recycled glass fine aggregate, slenderness ratio and eccentricity, the influence of different replacement rate of recycled glass aggregate on the failure modes, ultimate bearing capacity, axial displacement, cross lateral deflection, concrete strain and steel strain was analyzed. It is found that under both the eccentric compression or axial compression, the failure mechanism for reinforced recycled glass fine aggregate concrete column is similar with the normal reinforced concrete column. The ultimate bearing capacity is relatively high with 100% replacement of recycled glass fine aggregate. In addition, since it conforms to the plane section assumption, the ultimate bearing capacity of the specimens can be calculated according to the relevant domestic code. The results show that the waste glass fine aggregate can replace the general use of common sand in concrete column, without any influence on the performance.
