Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
Silt content in fine aggregates leads to the following significant changes in the engineering properties as:
Increased shrinkage:
- Silt particles are very fine and can fill the voids between larger sand particles, reducing the overall volume of the concrete mix.
- This leads to increased shrinkage as the concrete dries and hardens.
Decreased durability and Weakens bond characteristics:
- Silt can also weaken the bond between the sand particles and the cement paste, making the concrete more susceptible to cracking and other forms of deterioration.
Increased permeability:
- Silt particles make the concrete more permeable by increasing the voids between the cement and sand particles.
