| Question | ● Later Strength ● Moderate he |
|---|---|
| Type 3 Characteristics | ● Early strength ● High heat of hydration ● Low sulfate resistance |
| Type 4 characteristics | ● Low heat of hydration ● Late strength ● Moderate sulfate resistance |
| Type 5 characteristics | ● Low heat of hydration ● High sulfate resistance |
| Type 2 reason | ● Lower C3S & C3A ● Higher C2S ● Moderate Fineness |
| Type 3 reason | ● High C3S & C3A ● High Fineness |
| Type 4 reason | ● Low C3S & C3A ● High C2S ● Low Fineness |
| Type 5 reason | ● Low C3A ● Moderate - low fineness |
| nominal aggregate size and its effects on compressive strength of concrete | The smaller the size of the coarse aggregate the higher the strength. This is due to an increase in the surface area of the aggregates. |
| fineness modules and its effect on cement base requirements | Fineness: Fineness affects the surface area/mass ratio. The finer the material, the faster hydration will proceed. Therefore, fineness should be limited to allow hydration to proceed more slowly, resulting in a larger overall expansion. |
