The Absorbent Capabilities of Soil in Structural Works Are Related to the Quality of the Concrete

<p>In implementing building construction from low level to middle level, if the implementation is not using the services of a supervisory consultant, the implementers sometimes do not pay attention to the rules in the implementation. Especially in the implementation of casting the lower structure, namely concrete foundations and foot plates. Often workers do not use work floors or bases under the location where the casting will be used, to prevent water absorption caused by the soil, which can affect the strength of the lower structure. This research aims to examine the absorption capacity of soil in substructure work on the quality of concrete in the process of casting concrete foundations. Planning the substructure with concrete construction must be based on several aspects, one of which is paying attention to the type and texture of the soil. Soil type, apart from being related to strength and bearing capacity, is also related to the permeability of the soil. Permeability is the ability of the soil to allow water seepage through voids or pores in the soil. Due to the condition of this type of soil with very high water absorption capacity, it is necessary to pay attention to the implementation of concrete work that is in direct contact with the ground when carrying out the work, for example by using a plastic base or work floor, even at the level of simple work, in order to maintain the workability (thinness) of the concrete mixture. by taking into account the water cement factor (FAS) to maintain the quality of the concrete.</p>
