• Question 2: Piles driven at an inclination to resist forces that are not vertical are called:

  • Batter piles
  • Spur piles
  • Slanting piles
  • All of the above

• Question 3: A buried plate or block tied to and forming an anchorage for sheet piling or for a retaining wall is a:

  • Anchor plate
  • Block plate
  • Dead man

• Question 4: A method used advantageously in driving piles in sand, gravel, or soft packed clay due to high resistance offered by this material to piles driven by hammer is called:

  • Splitting
  • Jetting
  • Steam hammer

• Question 5: The most important factor affecting the strength of concrete is:

  • Water-cement ratio

Additional Information

• Question 6: The milky layer composed of cement and fine aggregate on the upper surface of the concrete mass during curing process due to an excess amount of water used is called:

  • Laitance

• Question 7: Stresses that cause cracks in reinforced concrete beams that are vertical at the center of the span and become more inclined as they approach the supports, where they slope at an angle of about 45 degrees, are called:

  • Shear stress

• Question 8: A type of pressure in an upward direction against the bottom of a structure, or a dam, a road, slab, or a basement floor is:

  • Buoyancy

• Question 9: A bearing pile surrounded by earth and supported entirely by friction, carrying no load at its end is:

  • Friction pile

• Question 10: The slow volume reduction of a cohesive soil (clayey soil) under applied loads as in foundation:

  • Settlement
  • Creep
  • Consolidation

• Question 11: The filling of waste spaces, embankments or construction cavities by sediment or debris carried by water or a pipe or a flume is:

  • Tremie

• Question 12: The moisture content of a soil at which a given amount of compaction produces the highest value of dry density:

  • Optimum moisture content

• Question 13: Have the effect of delaying the onset of hardening and usually also of reducing the rate of the reaction when it does start:

  • Retarding

• Question 14: Used to give plasticity or cohesion, mainly to mortars, but sometimes also to concrete. They function by entraining large amounts of air and therefore reduce strength:

  • Plasticizer

• Question 15: Means of spreading foundation loads over a wide area thus minimizing bearing pressures and limiting settlements:

  • Strap foundation
  • Matt foundation
  • Combined foundation

• Question 16: A measure of the size of mineral particles of the soil or rock; a physical characteristic of the particles of the soil which affects its mechanical properties, used in classification and identification of soils:

  • Index properties

• Question 17: It is the maximum angle which soil particles make with the horizontal without causing it to slide:

  • Angle of repose
  • Angle of internal friction

• Question 18: In the general column formula, the term L/r is known as:

  • Slenderness ratio

• Question 19: The total lateral force or base shear V given by V=ZIKCSW where Z is a numerical coefficient that depends on the seismic zone in which the structure is located. The Philippines is in Zone 4 where Z has the value of:

  • 3/16

• Question 20: The following are non-destructive tests in concrete except:

  • Pull-out test
  • Rebound hammer

• Question 21: In a long column (slenderness ratio >160), which of the following has the greatest influence on its tendency to buckle under a compressive load?

  • Modulus of elasticity

• Question 22: Honeycomb in concrete can be limited by the: Use of admixtures in concrete mix

• Question 23: A column of gravel or sand punched through less porous material to permit water to bleed off:

  • Filter drain

• Question 24: Flexural members will overall depth to clear span of ratios greater than 2/5 for continuous spans, 4/5 simple spans, is known as and should be designed as:

  • Spandrel beams

• Question 25: The state of liquidity occurring generally in granular soils:

  • Liquefaction
