Cement Type

Concrete Materials

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.
