4 cards from this section. Quick, good the night before a test.
What is workability in concrete?
Think about what aspects of concrete placement matter for its usability.
Name two shapes of aggregates and their impact on water content.
Consider how the shape affects packing and flow of the mix.
What is the primary purpose of estimating water content in concrete mix design?
Think about the role of water in the fluidity of concrete.
True or False: Angular aggregates require less water than rounded aggregates.
Consider how the shape contributes to the need for extra water.
Design a concrete mix for a desired slump of 80 mm using angular aggregates with an existing base water content of 200 kg/m³. Calculate the new water content.
Break the problem into parts by first calculating the slump changes.
You're tasked with mixing concrete that requires superplasticizers. If the original estimated water content was 250 kg, how do you calculate the revised content?
Focus on the adjustment percentage for superplasticizers and apply it accurately.
