The suitability of aggregate quality for repeated freezing and thawing is determined by a wear test of coarse aggregate using a Los Angeles testing machine. 2024 Problem A [No. 13] Which of the following statements regarding concrete mixes is appropriate? When setting the slump taking into account the compaction height, if the compaction height is 2m and 0.5m, the slump value for the 2m compaction height should be set higher. 2024 Problem A [No. 14] Which of the following statements regarding cold weather and hot weather concrete construction is inappropriate? When the daily minimum temperature is expected to be below 4°C during concrete construction, it must be constructed as cold weather concrete. 2024 Problem A [No. 15] Which of the following statements regarding concrete curing is inappropriate? When curing concrete using mixed cement type B, the wet curing period is shorter than that of concrete using ordinary Portland cement. 2024 Problem A [No. 16] When the construction conditions are the same, which of the following statements regarding the lateral pressure of fresh concrete acting on the formwork is inappropriate? The higher the temperature of the concrete, the greater the lateral pressure. 2024 Problem A [No. 17] Which of the following statements regarding the various foundation types in road bridge substructures is inappropriate? In the case of spread foundations, the shear surface when the foundation slides occurs deep in the foundation's flooring surface, so it is essential not to cause excessive disturbance to the ground during construction. 2024 Problem A [No. 18] Which of the following statements regarding the construction of steel pipe pile foundations using the driving pile method is appropriate? The driving control of the support pile foundation is performed by confirming that the embedded depth, rebound amount per driving at the time of driving is the same as that of the test pile. 2024 Problem A [No. 19] Which of the following statements regarding the construction of the cast-in-place pile method is inappropriate? With the all-casing method, the concrete top does not drop by pulling out the casing tube after the concrete is poured. 2024 Problem A [No. 20] Which of the following statements regarding the characteristics of various types of earth retaining works is inappropriate? A self-supporting earth retaining work is a method that resists by the rigidity of the earth retaining wall, and excavation is easy because the deformation of the earth retaining wall is small and there is no support within the excavation surface. 2024 Problem A [No. 21] Which of the following statements regarding the points to note when erecting a steel road bridge is inappropriate? When moving the erection members vertically, it is desirable to make the throwing slope downward in order to increase the safety of the throwing work. 2024 Problem A [No. 22] Which of the following statements regarding points to note when welding steel road bridges is inappropriate? Undercuts are a major cause of stress concentration and can also promote corrosion, so they should not be present even in joints that are not considered to be affected by fatigue. 2024 Problem A [No. 23] Which of the following statements regarding the tightening of high-strength bolts in steel road bridges is appropriate? Tightening of high-strength bolts should be performed starting from the bolt in the center of the connecting plate and moving sequentially to the bolts at the ends, with double tightening. 2024 Problem A [No. 24] Which of the following statements regarding reinforcement methods for concrete structures is inappropriate? Seismic isolation methods can reduce the displacement of components during earthquakes. 2024 Problem A [No. 25] Which of the following statements regarding deterioration of concrete structures due to neutralization and its characteristics is inappropriate? The neutralization depth of concrete is generally considered to be proportional to the square of the number of years of service after the completion of a structure. 2024 Problem A [No. 26] Which of the following statements regarding the construction of river embankments is appropriate? When constructing embankments, temporary drainage channels are installed at appropriate intervals to allow rainfall to flow down in order to prevent slope erosion due to rainfall, and a drainage gradient is provided in the transverse direction of the embankment to prevent rainfall from concentrating. 2024 Problem A [No. 27] Which of the following statements regarding the foundation protection work installed in front of the river bank is inappropriate? When randomly stacking irregular concrete blocks, the riverbed is leveled before stacking, so construction becomes difficult when the water depth becomes deep. 2024 Problem A [No. 28] Which of the following statements regarding excavation work on river embankments is inappropriate?
