Practice B.Tech Civil Workability of Fresh Concrete in the app →Per §5.2 (Road Research Laboratory, UK), 'workability' of fresh concrete is best defined as:Per §5.3.1, the SINGLE most important factor governing the workability of fresh concrete is:Per §5.3.4, rounded aggregates produce more workable concrete than angular or flaky aggregates principally becPer §5.3.5, between two aggregates of equal volume, which one will give the higher workability of concrete?Per §5.3.6, a well-graded aggregate gives BETTER workability mainly because:Per §5.3.7, the air-entraining agent increases the workability of fresh concrete by acting:Per §5.3.8, an INCREASE in ambient temperature generally has what effect on the workability of a given concretPer §5.4.1 (Slump Test), the cone is filled with concrete in how many layers, and each layer is tamped with hoPer §5.4.1, in the slump test the tamping rod diameter used to compact each layer is:Per §5.4.1, a SHEAR slump (rather than a true slump) in the slump test typically indicates:Per Table 5.1, the slump range corresponding to a 'MEDIUM' degree of workability lies in approximately:Per Table 5.1, the slump range corresponding to a 'HIGH' degree of workability is approximately:Per §5.4.2, the K-Slump tester is described as a HANDY field apparatus whose total weight is approximately:Per §5.4.3, the Compacting Factor Test was developed in Great Britain in the year:Per §5.4.3, in the Compacting Factor Test the compacting factor is computed as:Per §5.4.4 (Flow Test), the flow percentage is computed from the spread diameter (in cm) of the concrete pat bPer §5.4.4, in the standard Flow Test the flow table is dropped through 12.5 mm at the rate of:Per §5.4.5 (Kelly Ball Test), the metal hemispherical indenter used has a diameter of about 15 cm and weighs aPer §5.4.5, in the Kelly Ball test the minimum depth of concrete needed for a valid result is:Per §5.4.6 (Vee-Bee Consistometer Test), the test is described as most suitable for assessing:Per §5.5, segregation in fresh concrete refers to:Per §5.6, 'bleeding' of concrete is best defined as:Per §5.6, 'laitance' formed at the surface of concrete by bleeding is:Per §5.6, harmful effects of bleeding listed in the source include all of the following EXCEPT:Per §5.6, remedial measures listed by the source for excessive bleeding include all the following EXCEPT:
