To prevent this, measures such as cooling the mixing water or using chilled aggregates may be necessary.

86. What is Grunting?

Grunting is a term used in construction to describe a noise or vibration that occurs when a pile is driven into the ground. It is caused by the resistance of the soil against the pile, which creates a sudden increase in stress and pressure. This increase in pressure causes the pile to vibrate, resulting in a loud, low-frequency noise that sounds like a grunt. Grunting can be an indication of the pile being driven to the required depth, but it can also be a sign of potential issues such as pile damage or soil instability.

93. What is the minimum recommended weight of fine aggregate for sieve analysis as per ASTM C136?

According to ASTM C136, the minimum recommended weight of fine aggregate for sieve analysis is 300 grams. The sieve analysis is a test used to determine the particle size distribution of a sample of aggregate. In the test, the sample is passed through a series of sieves with progressively smaller openings, and the amount of material retained on each sieve is weighed. The results of the test are used to determine the grading of the aggregate, which is an important factor in the design of concrete mixes.

94. Duration in hours for CBR samples to be soaked?

The duration for soaking CBR (California Bearing Ratio) samples depends on the type of soil being tested. According to ASTM D1883, the standard test method for CBR of soil in the laboratory, the samples should be soaked for 96 hours (4 days) if the soil has a plasticity index greater than 10, and for 24 hours if the soil has a plasticity index less than or equal to 10. Soaking the samples helps to simulate the effect of moisture on the soil in the field and ensures accurate test results.

95. What is the bearing capacity of soil?

The bearing capacity of soil is the maximum load that the soil can support without experiencing excessive settlement or failure. This capacity depends on factors such as soil type, moisture content, and the depth and size of the foundation. It is a critical factor in the design of structures such as buildings, bridges, and roads.

96. What do you mean by honeycomb in concrete?

Honeycomb in concrete refers to a defect in the surface finish of the concrete where voids or cavities are left in the hardened concrete, resembling a honeycomb. This occurs when the fresh concrete is not properly placed or compacted, causing air pockets to form in the mix. This can happen when the concrete is not vibrated or consolidated properly, or if the formwork is not properly sealed, allowing the concrete to escape.

102. What are the major difficulties faced during pumping concrete works?

Difficulties are discussed below,

  1. The force needs to overcome the friction between concrete and the pumping pipes along with the weight of concrete and the pressure head.
  2. Segregation and Bleeding are the major problems associated with pumping.
  3. Aggregate selection is important in this process to reduce errors in work.

103. Reason for concrete being weak in tension?

Concrete is a combination of materials like several aggregate types, cement, pozzolana, water, air, etc which are stick together with a cement paste. The zone called the “interface zone” is the weakest link in the structure. During compression, that interface is the only to transfer compressive stresses from aggregate to aggregate. Which does not require exceptional strength.

While the scenario under tension is not the same. The aggregates in tension are trying to pull away from each other and the bond is what holds it tightly. Since it is significantly weaker than the aggregates, it is what results in failure.
