ANALISIS KUAT TEKAN BETON MENGGUNAKAN LIMBAH BATU BATA SEBAGAI PENGGANTI SEBAGIAN AGREGAT KASAR

Abstract

In a construction project, unused bricks often become waste. This waste has accumulated, which disturbs mobility
and aesthetics at the project site. To reduce this waste, a solution that can be done is to reuse the remaining bricks
as other environmentally friendly construction materials. Waste brick can be recycled to be developed in the
manufacture of concrete. The choice of brick waste as a concrete mixture is due to its hard structure and similar
to natural aggregates. The use of brick waste as a substitute for some coarse aggregate in concrete is expected to
reduce the use of natural rock. The purpose of this study was to analyze the comparison of the results of the
compressive strength of concrete in normal concrete and concrete using brick waste. The author conducted this
research by comparing the results of compressive strength of normal quality fc '25 concrete with concrete using
brick waste as much as 5% and 10% as a substitute for coarse aggregate. From the results of this study, the
compressive strength of concrete with brick waste as much as 5% is 25.78 Mpa and with the use of brick waste as
much as 10%, the compressive strength of concrete is 22.02 MPa which is smaller than the compressive strength
of normal concrete which is equal to 29.02 Mpa. From these results it can be seen that there is a decrease in the
compressive strength of concrete against normal concrete at the age of 28 days using 5% brick waste is 11.16%
and with 10% brick waste a decrease of 24.12%
