Abstract

Pumice is a type of light-colored rock that contains cavities made from glass-walled bubbles and is usually referred to as volcanic silicate rock glass. These rocks are formed from magma acid through volcanic eruptions that eject material into the air, which then experiences horizontal transport and accumulates as pyroclastic rocks. However, there are also pumice rocks that were formed from dead and weathered sea coral. The pumice stone sea coral species are spread where coastal sea coral reefs grow. In this experiment, volcanic pumice silicate (SP-2) sourced from Gresik is substituted as coarse aggregate in the manufacturing of lightweight aggregate concrete. The result obtained was a lightweight aggregate volume silica volcanic pumice SP-2 at 717 kg/m3. In the testing phase, for a mixture of cement, water, sand and pumice lightweight aggregate concrete, the weight gained per cubic meter of volcanic pumice silicate (SP-2) was 1850 kg/m3. From the test results, pumice stone qualifies as a lightweight aggregate for the manufacturing of lightweight structural concrete. In this study, a testing of the compressive strength of the specimen cylinder (15 x 30cm) was also conducted. Testing results show that concrete compressive strength at age 7, 14 and 28-days obtained values of 15.23 Mpa, 13.86 Mpa and 13.88 Mpa, respectively. Additionally, splitting tensile strength obtained results of 5.16 Mpa, 4.70 Mpa and 4.71 Mpa at the same age
