59. Frage
Which of the following images shows the appropriate tool to measure the slump of concrete?
Antwort: B
Begründung:
Concreteslumpis measured using theslump cone (Abrams cone)apparatus and tamping rod in accordance with standard procedures (e.g., ASTM C143). The test measures the vertical "settlement" of fresh concrete after a cone-shaped mold is filled in layers, consolidated (rodded), struck off, and then lifted vertically so the concrete subsides; the drop in height is the slump. TheEssentials of Civil Engineering Materialstext describes the slump test as forming a specimen inside ametal cone, removing the cone, and measuring how much the top settles ("slumps"), and it outlines the typical steps: wet the cone, fill in layers, tamp with a rod, strike off, and measure the slump. The correct tool set therefore is the image that shows theslump cone with base and tamping rod, which corresponds toOption C.
60. Frage
What would be the best step for an engineering team to propose to a client when reviewing a concept before a project is initiated?
Antwort: A
Begründung:
Before a project is initiated, the essential decision is whether the concept isviable-technically, economically, and in terms of risks, constraints, and stakeholder needs. Afeasibility studyis the recognized pre-initiation step that evaluates alternatives at a high level, confirms the problem/need, examines constraints, and establishes whether moving into design is justified. In civil engineering systems development, feasibility is treated as an early stage that precedes planning and detailed design, with early cost and uncertainty considerations explicitly tied to the feasibility stage. Life cycle cost analysis is valuable, but it is typically one component used within feasibility/planning decisions rather than the primary "best step" to propose before initiation. Preliminary and detailed design occur after feasibility confirms the concept should proceed.
Therefore, the best step to propose at concept review before initiation is afeasibility study.
61. Frage
What does a system curve illustrate?
Antwort: B
Begründung:
Comprehensive and Detailed 150 to 200 words of Engineering documents and resources:
In pumped/pressurized pipe systems, thesystem curverepresents the hydraulic requirement of the piping network: the relationship betweenflow rate (Q)and thehead requiredto overcome elevation differences and losses. As flow increases, friction and minor losses rise (often approximately with Q² in turbulent flow regimes), so the system's required head increases with Q. This curve is used with a pump curve to find the operating point where pump head equals system head at a given flow. Standard civil engineering hydraulics references define head loss as a function of flow through friction and fittings, and system behavior is expressed by total head (static + losses) versus flow, which is exactly what the system curve shows.
Therefore, the system curve illustratestotal head loss (and required head) in the pipe system as a function of total flow, matching optionC.
62. Frage
What joints are used in the construction process to separate two concrete pours?
Antwort: B
Begründung:
Aconstruction jointis the intentional interface between two separate concrete placements, created when a pour is stopped and later resumed due to sequencing, access, work limits, or planned staging. It marks the boundary between "old" and "new" concrete and is detailed to ensure adequate bond, alignment, and structural performance (e.g., surface preparation, keyways, dowels, waterstops where required). By contrast, control (contraction) joints are intended tocontrol shrinkage cracking, expansion joints accommodate thermal movement, and isolation joints separate slabs from adjacent elements to prevent restraint stresses.
Materials references describing slab jointing distinguish construction joints as the joints that occurbetween placements(separate pours) versus joints intended primarily for movement or crack control. Therefore, the joint used to separate two pours is theconstruction joint.
63. Frage
A civil engineering technologist is taking a sample of concrete cylinders from a truck. When should the sample be taken?
Antwort: C
Begründung:
Concrete cylinder samples must represent thedelivered batch, so sampling must avoid the non-representative portions at the beginning and end of discharge where segregation and water/aggregate distribution can differ.
ASTM C172/C172M sampling practice requires collecting acomposite samplefrom themiddle portionof the load: specifically, not before about10%and not after about90%of the batch has been discharged, using two or more portions taken at regularly spaced intervals. A paper hosted by ASTM discussing sampling from truck mixers references ASTM C172/C172M and its requirement for collecting multiple portions from the discharged batch. Training/field guidance consistent with ASTM C172 also states sampling should occur after
~10% and before ~90% of discharge (i.e., the middle of the load). Therefore, the correct answer isin the middle of the load (Option C).
