| dc.description.abstract | In this study focus on the evaluation of concrete strength made of brick and stone aggregate by
using cylinder. one sizes cylinder diameter (4 inch) are used to find out the effect of core
diameter on the core strength. Three different sizes of rebar diameter (10mm, 12mm, 16mm)
without rebar are used to evaluation the effect rebar presence in core on the core strength.
concrete was prepared with two mixing ratios (1:1.5:3 and 1:2:4) & different materials
(Bricks & stone chips) Each mix ratio of fresh concrete, three ∅4"x8"cylinder samples were
taken and tested at 28 days. From the cylinder, 48 numbers cylinder of 4inch diameter core
samples were taken. Each diameter of core, three samples were taken without presence of rebar
and other core samples were taken with presence of 10mm, 12mm, 16mm rebar in each set of
core samples. The cylinders and concrete core samples were tested. The test results are
analyzed.
From the test results, it is found that cylinder strength (with rebar) decreases significantly with
compare to cylinder strength (without rebar). Strength of with rebar(10mm,12mm,16m) is
decreased about 13.60% and 17.64%,21.93% respectively with compare to cylinder strength
(without rebar) for stone & ratio 1:1.5:3. Strength of with rebar(10mm,12mm,16m) is decreased
about 12.11% and 22.05%,30.76% respectively with compare to cylinder strength (without
rebar) for bricks & 1:1.5:3. respectively with compare to cylinder strength of between mixing
ratios (1:1.5:3 and 1:2:4) & different materials (Bricks & stone chips), without rebar &
different rebar.
It is found that cylinder strength (with rebar) decreases significantly with compare to cylinder
strength (without rebar). Strength of with rebar(10mm,12mm,16m) is decreased about 10.62%
and 21.76%,23.42% respectively with compare to cylinder strength (without rebar) for stone &
ratio 1:2:4. Strength of with rebar(10mm,12mm,16m) is decreased about 16.10% and
28.14%,35.11%, respectively with compare to cylinder strength (without
rebar) for bricks & 1:1.5:3, respectively with compare to cylinder strength of between mixing
ratios (1:1.5:3 and 1:2:4) & different materials (Bricks & stone chips), without rebar & different rebar | en_US |
