Abstract

Pumice sand is a bright colored butian type, containing foam made from glass-walled bubbles and
usually referred to as silicate volcanic glass granules. This pumice sand can be used as a substitute
for normal sand as fine aggregate in a mixture of concrete mix. Based on the characteristic test
examination, it can be seen that in testing the characteristics of pumice sand to the specifications
of normal sand in specific gravity testing and weight testing of quicksand obtained results that
are smaller than the specifications of normal sand and absorption tests obtained results greater
than specifications on normal sand. The results of the normal sand compressive strength at BN is
250.95 kg /cm2 while the results of the floating sand concrete compressive strength on BPA is
224, 965 kg /cm2. Based on the research it can be concluded that with the same quality of concrete,
the quality of K-250 is different in comparison to the compressive strength of concrete in normal
sand and pumice sand concrete shows almost the same results. Therefore, more in-depth research
is needed regarding the use of pumice sand instead of normal sand in a mixture of concrete mix.
