Recycle Concrete Waste from Laboratory as Aggregates for Concrete

Concrete block from laboratory can be recycled to lessen the cost of transportation to
transport the waste to the landfill and also diminish the absolute of concrete wastes.
Improving and recycle the crushed concrete block as coarse aggregate would lead to
economic profits. This experiment study aimed to use crushed concrete block from
the concrete laboratory as recycled coarse aggregate in concrete mixture. The
controlled concrete mixture will be correlated with concrete mixture added with
some amount of recycled aggregates as replacement with normal coarse aggregates.
The experimental was conducted to compare the strength of normal coarse
aggregates and recycled coarse aggregates that have been added in concrete mixture
to study the hypothetical use of recycled coarse aggregates in constructions. Before
conducting the experiment, the concrete block waste will be crushed to coarse
aggregate size and sieving process will be carried out to get the desired size to
produce new concrete block. Finally, compressive strength and tensile strength tests
will be evaluated. The result of the tests will be altered based on the different ratio of
recycled coarse aggregate replacement in the concrete mixture.
