Abstract

In the effort of public welfare, the government through the provision of boards such as residential houses, either through private parties or SOEs, often gets the location of the land base in the form of soft land or ugly carrying capacity, which impact on maintenance and repair costs far greater than the cost of purchase. Researchers studied through the stabilization of soil with cement materials and soil mixed variations that occur, so that the soil as a buffer building is known strength or carrying capacity. On improving the strength of the road body with soil stabilization through the CBR test, it can be obtained an increase in soil bearing capacity. Sondir testing for the foundation design data either through conical resistance (qc) or by friction can be obtained by the base area of the foundation foot. If the value of qc is large then the footprint of the foundation foundation, especially shallow foundations will be small. With soil and cement stabilization studies in the laboratory, with different variations and durations can be obtained a reference to the increase in the carrying capacity of the shallow foundation footing and the required thickness of the layer based on the pattern of voltage distribution with the mathematical equation y = 0.7935x - 6.79 where y = power support for soil (kg / cm2), and x =% plus cement and R = correlation.Kata kunci: Tanah, Semen, Daya Dukung, Sondir.

Abstract

Granular of soil as a material supporter of building foundations, heavily influenced by the physical properties of water. Moreover, the fine-grained soil clays in particular, due to water entering the soil particle then inflate and vice versa due to reduced ground water will shrink. Red clay soil stabilization with lime and cement materials, seeks to increase the carrying capacity of the soil as subgrade layer to buffer the load through the foundation component that serves to spread the load on it to buffer the soil section. In addition to the added material lime and cement as filler material also serves as a lasting cementation thus increase the carrying capacity of the red clay soil. Better material cemented its CBR value increase of the lime.

Abstract

Soil materials that the grain size of the composition can comprise coarse material (gravel, sand) and fine materials (silt and clay). At the material / soil materials that include fine-grained soil that contains granules ΓΈ 0.075 mm over 50% will be dominated by clay content. This material will have a high value of plasticity and low power as well as developing a sizeable shrinkage. Lime that has binding properties (lime stone) when added to the material clay changes will provide both improved quality, bulk density, as well as lime-enabled so the added material on clay red around POLINES as filler material (filter) with different variations in the mix and treatment peneraman and soaking would boost its strength tested by the carrying capacity by means of CBR (California Bearing Ratio) test results in the laboratory value of CBR plans on condition brooded until 7 days: CBR its 2.4 kp + 20.8 with a level of correlation R = 0.9328 , And soaked conditions until 7 days: his CBR kp 4.4 - 0.8 with a degree of correlation R = 0.9874.
