“…Additionally, the samples for the unconfined compression test had a diameter of 40 mm, and a height of 80 mm. Due to the fact that the curing condition possessed a great influence on the strength properties of the sample [ 32 ], the reinforced effect of nano-SiO 2 on samples under both cured and uncured conditions was tested in this study. Certain prepared specimens were tested after being prepared, which represented the samples under the uncured conditions.…”

A rapid growth in the population leads to a large increase in engineering construction. This means there is an inevitability in regard to building on problematic soils. Soil reinforcement becomes an important subject due to the fact that it is a concern for engineers and scientists. With the development of nanotechnology, more and more nanomaterials are being introduced within the practice of soil reinforcement engineering. In this study, the reinforcing effect of novel nanomaterial nano-silica (SiO2) applied to different kinds of soils was systematically studied. The nano-SiO2-reinforced soil possessed lower final water evaporation loss, and evaporation rates. The nano-SiO2 increased the shear strength of clayey soil and sandy soil under both cured and uncured conditions, but the reinforcing effect on clayey soil was more obvious. The addition of nano-SiO2 promotes the friction angle and cohesion of clayey soil; further, it also increases the cohesion of sandy soil. The unconfined compressive strength of clayey soil was enhanced by nano-SiO2, meanwhile, the nano-SiO2-reinforced soil possessed greater brittleness. The microstructure of nano-SiO2-reinforced soil is shown via SEM analysis, and the results of X-ray diffraction (XRD) tests show that there are no new mineral components generated during the reinforcing process. It was also found that nano-SiO2 possessed little influence on the soil pH value. Adding nano-SiO2 will not damage the original chemical environment of the soil. The microstructure of nano-SiO2-reinforced soil was observed to prove the results above. In general, nano-SiO2 is an excellent soil additive that can improve the mechanical properties of both clayey soil and sandy soil effectively. This research provides more ideas and directions for the purposes of selecting soil reinforcement materials.

The paper objective presents the Field measurement of the Rubble Masonry Ground Deformation under Consideration of the Jackfruit Tree Development after 8 years. Results show the crack’s appearance on the grout surface which made small fragments with different lengths and diameters areas sizes. The maximum values of the depths, widths, and lengths of cracks show 30mm, 35mm, and 90 mm; whereas the maximum length appeared on the surface area sizes of 2.350m at the stool; compared with the minimum value of 5mm distance 1.5m. On the other hand, the brick lining increasing the pavement obtained 7cm. Moreover, the development cycle of the jackfruit was done carefully by the Vietnam Standard which included care time, fertilizer, and water supply cycle. Results described particularly in the heights, diameters, and years old as 3 months, 1 year, 3 years, 5 years, and 8 years: 0.3mx15cm; 1.2mx35cm; 2.5mx58cm; 4.0mx72cm; and 6.0x99cm. In conclusion, the research results can use for the references for civil, road, and geology engineering to forecast and it is not recommended to plant jackfruit trees near the ground of houses, pavements, and roads a distance of less than 5m; replace with a distance of rather than 5m to be safe ground.
