Lightweight concrete is concrete that has a lower density than normal concrete. Lightweight concrete is an innovative type of concrete made by adding additional materials such as foam and replacing some of the cement with glass powder. This research uses materials such as cement, water, foam agent and glass powder with a target weight of lightweight concrete ranging from 1140 – 1840 kg/m3. Th…
Lightweight concrete has a density that ranges from 1.440-1.840 kg/m3 compared to normal concrete with a density of about 2.240-2.400 kg/m3. The materials used in this research are cement, water, foam agent and glass powder. This research uses variations of water cement ratio 0,4; 0,5; and 0,6 with 30% glass powder, foam and slurry ratio of 0,35: 0,65 and 1: 40 for foam agent and water. In this…
Peat soil exhibits distinct characteristics compared to clay soil. Physically, it is recognized as soil with high organic content, a very high water content, large pore size, and the presence of fibers. Technically, it has very high compression and very low shear strength. To determine the shear strength values of this peat soil, two tests were conducted: in-situ shear strength testing using a …
