Soil is a crucial component in the construction process. In civil engineering industry, the quality of the underlying soil used as the foundation of a construction plays a vital role in providing strong support. To ensure optimal load-bearing capacity, the clay soil used in this study was obtained from Jl. Siak II, Masjid Raya Provinsi Riau, Pekanbaru, which is known to have issues with soil be…
Peat soil is a type of soil that is not good for civil engineering building construction. This is because peat soil is unstable, has a very high void ratio and water content, so its carrying capacity is low. To improve poor soil conditions, one of the methods that can be used is stabilization. This study aims to determine whether a mixture of quicklime and palm ashes can be used as a stabilizin…
Peat soil has a high organic content and low ash content, so it has technical properties that are detrimental to civil structures. Several methods of improving and stabilizing peat soils have been applied, but each has its own advantages and disadvantages. Therefore, a study was conducted to determine the effect of stabilizing peat soil using quicklime and palm oil ash (POA), the tests carr…
Soil is one of the media that is used with a function as a foundation, both the foundation as the foundation of a building and road pavement. Soil has a function to continue the forces acting on it. Palm fiber ash is a processed product from palm fiber waste which is burned to ashes and passes through filter No.#200. This soil improvement was carried out to determine the effect of mixing added …
