The term ________ of concrete is used to mean the compaction between aggregate and aggregate; between aggregate and reinforcement and between aggregate and forms.

The term ________ of concrete is used to mean the compaction between aggregate and aggregate; between aggregate and reinforcement and between aggregate and forms. Correct Answer Consolidation

The main aim of consolidation of concrete is to eliminate air Bubbles and thus to give maximum density to the concrete. The importance of consolidation of concrete can be seen from the fact that a presence of 5% of voids reduces 30% strength of concrete.

Which of the following statements are wholly correct regarding broken-brick aggregate useable in concretes? 1. Broken-brick aggregate is obtained by crushing waste bricks, and it has a density varying between 1000 kg/m3 — 1200 kg/m3. 2.

Nominal cover to reinforcement is provided to 1. protect reinforcement against corrosion. 2. provide share resistance. 3. protect reinforcement against fire. 4. develop sufficient bond strength along surface area of reinforcement bars. Which of the above statements are correct?
Permeability in concrete is studied towards providing for, or guarding against, which of the following features? 1. The penetration by materials in solution may adversely affect the durability of concrete; moreover, aggressive liquids 'attack' the concrete. 2. In the case of reinforced concrete, ingress of moisture and air will result in corrosion of steel leading to an increase in the volume of steel, resulting in cracking and swilling of the concrete cover. 3. The moisture penetration depends on permeability and if the concrete can become saturated with water it is less vulnerable to frost action.
Workability of concrete can be measured using slump, compaction factor and Vee-bee time. Consider the following statements for workability of concrete: (i) As the slump increases, the Vee-bee time increases. (ii) As the slump increases, the compaction factor increases. Which of the following is TRUE?
Consider the following statements: 1) workability of concrete increases with the increase in the proportion of water content 2) Concrete having small-sized aggregates is more workable than that containing large-sized aggregate 3) For the same quantity of water, rounded aggregates produce a more workable concrete mix as compared to angular and flaky aggregates 4) A concrete mix with no slump shown in the slump cone test indicates its very poor workability Which of the above statements are correct?
