Karakteristik Campuran Tanah Dan Semen Yang Dipadatkan Pada Berbagai Campuran Sebagai Upaya Perbaikan Lapisan Tapak Pondasi Dangkal Dengan Uji Sondir

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.
