What is the typical slump value range for pavement applications?
Think about how the slump is defined.
Name one factor that influences water content in concrete.
Consider what materials we use in concrete.
What is the typical range of slump for pavement concrete?
Consider the specifications for workability.
True or False: More water always leads to stronger concrete.
Think about the water-cement ratio.
Design a concrete mix for a pavement application with a target slump of 70 mm. Given your aggregates are angular, describe how you would adjust your water content estimation.
Review the steps you learned on how aggregate shapes affect water recommendations.
Discuss the long-term impacts of underestimating water content in a concrete mix for pavements. What signs might indicate issues later on?
Think about how the concrete behaves over time with insufficient water.
