| Summary: | Concrete slump test (or simply the slump test) is an in situ test or a laboratory test
used to determine and measure how hard and consistent a given sample of concrete is
before curing. The concrete slump test is, in essence, a method of quality control. A
higher slump concrete result means the concrete sample is not stable and a lower
slump concrete result means the concrete is firm. A manual slump test is the
problems that always occur when applying this method test. Inconsistent speed and
lateral vibration while lifting up the cone and human error that cause the cone move
in slight angular direction are the main problem that need to be counter with. This
project presented is to overcome the problems occur in handling the manual concrete
slump test. The aims of the project are to design and produce semi automatic slump
test prototype and to analyst and test the functionality of the lifter. Several designs
of semi automatic slump test were designed and the electrical motor lifter was
selected. The design uses electric motor lifter to move the slump cone in proper
direction as well as overcoming the problems occur in manually done slump test.
This selected design then fabricated and undergo the functionality test. In the end, the
collected data from the functionality test between manual operation and semi
automatic slump test is analyzed with using Pearson correlation. The result carried
out shown that The Semi Automatic Slump Test could replace the manual slump test
due to Pearson Correlation result’s obtained 0.9807 nearly to 1. Semi automatic
Slump equipment is compatible and fits with the slump test value obtained by
standard equipment such as that described in British Standard (BS 1881: Part 102:
1983). |
