The Impact

A new soil water characteristic curve (SWCC) experiment contemplating urea concentration is presented in the paper. We focus on the impact of the SWCC considering urea concentration test method for materials selection and introduction, experimental results, and finally, we have conducted some experiments of SWCC and obtained some valuable data which could affect urea concentration. By using linear fitting, an exponential function between water content and suction and urea concentration is established.

The purpose of this study was to determine the effect of substitution ketapan seed to chemical and organoleptic properties of  the resulted snack food, knowing the exact level of substitution, so obtain the snack food liked the panelists. The design used in this study was completely randomized design (CRD) with single factor that influences the concentration of seed flour substitution ketapan seed consisting of 5 treatments. Each treatment be repeated 3 times. The data obtained was analyzed by Analysis of Variance (ANOVA), if there was a difference between the treatment of advanced test conducted by Duncan`s Multiple Ranges Test Method (DMRT) at the level of 5%. Substitution of wheat flour with ketapan seed flour  affects the snack food produced, which can reduce the water content of the snack food and increase levels of protein and fiber snack food. Ketapan seed flour substitution preferred by the panelists was substitution ketapan seed flour up to 30% with a value of 3.52 and the criteria snack food produced had a water content of 3.67%, 15.10% db protein content, fiber content of 3.64 % db, brownish yellow color (2.95), a rather tasted wheat flour (3.35), and crispy (3.60).

The thin plate penetration test method was presented by Professor T.S. TAN for the determination of undrained strength in high water content sludge. Based on the method, a thin plate penetration test device is designed. Through the thin plate penetration indoor test of dredged sludge, the unload weight and interval time of this test method are studied. The results shows that: if the water content range of soil sample can be segmented, and determine the appropriate interval time for unloading in each segment of the water content range, the efficiency and accuracy of thin plate penetration test method can be improved.

Performance Analyze

By using repeated load triaxial test method, test results of permanent strain of fine sand were obtained. The main factors affecting permanent strain of fine sand samples are water content, degree of compaction and deviator stress. Permanent strain of sand is less sensitive to moisture when compared to clay and silt. Well compacted fine sand subgrade is less affected by the change of water content, which illustrates a more stable long-term performance. Analyze from meso-structure, the ellipsoid shaped particle is less stable than sphere shaped one under the effect to repeated load. Fine sand with smaller amount of ellipsoid shaped particle would have better dynamic behaviors. Predicting models of permanent strain with basic soil physical properties were established using regression analysis.

Alternative Test Method

It has been reported that, depending on the material used, batches of concrete having the same slump value behave differently when vibrated. It is therefore to be expected that batches of concrete having the same slump value and containing the same amount of powder will have different properties depending on the material used. However, these batches of concrete are treated as concrete of the same quality since, at present, no alternative test method has yet been established as a substitute for the slump test. This study proposed new simplified experimental methods for vibration properties of fresh concrete. By using these methods, the vibration characteristics of fresh concrete containing fly ash (FA) and containing a large amount of cement were exhibited.
