Quality Control of Concrete in the Southern Region of Kingdom of Saudi Arabia Using Local Materials
A common concern amongst civil engineers is producing a good quality
concrete on-site. This paper reports results of a study
carried out to examine the quality of normal strength concrete
production in the southern region of Kingdom of Saudi Arabia (KSA)
made from local coarse aggregate namely Basalt. As all data were
analyzed and examined statistically using Chebyshev’s theorem
and the Statistical Empirical Rule (SER) method presented herein. It is
concluded that, the normal distribution of all test results -in
terms of the quality of concrete mix- was strongly agree with
Chebyshev’s theorem and ACI 318-14 section 5.6.3. In addition, these
results were considerably better than the Statistical Empirical Rule
(SER) method. Overall, these concrete mixes, in this investigation,
with 28 days compressive strength of 35 MPa can be used confidently in
concrete structure applications.
