Abstract

A solid foundation is a concrete mix using steel reinforcement, but the reinforcement has the disadvantage of being corrosive when used in coastal areas. Therefore, this research uses strapping bands as a substitute for steel reinforcement. This research is focused on the manufacture of mortar plates for lightweight construction, especially in foundation parts such as footing foundations.   This research used 5 (five) variations of slab mixture including, variation A1 which is mortar slab without additional strapping band, variation B1 which is mortar slab with additional 3 pieces of strapping band as thick as 1 layer on each top and bottom layer, so on up to variation B4 as thick as 4 layers. The results of the mortar plate bending test obtained the value of the bending moment of variations A1, B1, B2, B3, and B4 are 0.148 kN.m; 0.183 kN.m; 0.222 kN.m; 0.278 kN.m; 0.325 kN.m. Then the maximum bending moment value is averaged in the variation that uses a 4-layer thick strapping band. From this research it can be concluded that to get a high bending moment value, the more strapping bands are used.

Abstract

Very soft and ultra soft soils are types of soil with high water content, very soft consistency, and low bearing capacity, making them susceptible to deformation and subsidence due to loading. This study aims to determine the correlation between volume change parameters and consolidation in very soft and ultra-soft soils based on laboratory testing (oedometer test) and in-situ testing (Cone Penetration Test with Pore Pressure Measurement/CPTu). The parameters studied include the consolidation coefficient (Cv), compression index (Cc), volume change coefficient (mv), and parameter α as the correlation between the mv value from the oedometer test and the corrected cone resistance (qt) value from CPTu. The results show that the Cv value varies with each increase in effective stress. Additionally, the consistency of the α correlation values indicates that CPTu can be used to quickly and efficiently estimate volume change coefficient (mv) values in the field. Therefore, CPTu can serve as an alternative for predicting the behavior of very soft and ultra-soft soil conditions in situ in a more representative manner.
