Question: 1 / 400

What effect do temperature variations have on the curing process of aggregate bases?

They only affect the initial setting time

They alter moisture loss and curing strength

Temperature variations significantly influence the curing process of aggregate bases, particularly in terms of moisture loss and curing strength. When temperatures are high, evaporation rates can increase, leading to faster moisture loss from the aggregate base. This can result in inadequate hydration of the materials, ultimately affecting the bonding and strength development of the aggregate base.

Conversely, lower temperatures can slow down hydration processes, potentially delaying the strength gain of the material. Therefore, maintaining optimal temperatures is crucial to ensure that the aggregate base cures properly, achieving its intended strength and performance characteristics. Addressing these temperature-related impacts is essential for ensuring the durability and functionality of the constructed base.
