The data presented information on flexural strengths of reinforced concrete element:

Deflection value at points of flexural load application on the beam.

Failure load of reinforced concrete beams with fine aggregate replacement at 7, 14, 28 and 90 days of curing.

۲٫ Experimental design, materials and methods The aggregate materials and cement used for this research were collected from different locations in Lagos state, Nigeria (6.6080°N, 3.6218°E). Waste glass particles (Fig. 1.) collected from Agbara, Ogun State, Nigeria (7° ۱۵′ ۰″ North, 3° ۲۴′ ۰″ East) was used to partially replace sand as fine aggregate in proportions of 0%; 10%; 20%and30% [1]. The beams produced were subjected to flexural strength test as shown in Fig. 2 at different curing age. Flexural load and deflection values for 0%, 10%, 20% and 30% replacement at 7 days are presented in Tables 1–۴ respectively. Tables 5–۸ shows the flexural load and deflection values for 0%; 10%; 20% and 30% replacement at 14 days respectively, Tables 9–۱۲ shows values for 28 days and Tables 13–۱۶ shows values for 90 days for 0%; 10%; 20% and 30% respectively.
