What is a potential consequence of not properly controlling temperature during aggregate testing?

Not properly controlling temperature during aggregate testing can lead to inconsistent test results. Temperature affects various physical and chemical properties of materials, including moisture content, density, and the behavior of aggregates under stress. If aggregates are tested at varying temperatures, fluctuations in these properties can introduce variability in the test outcomes. For example, at higher temperatures, the moisture content can evaporate more quickly, which could result in a lower weight measurement compared to testing at controlled, optimal temperatures where moisture remains consistent. Consequently, test results may not accurately reflect the true performance of the aggregate material, making it difficult to ensure quality and reliability in construction projects.

The other aspects mentioned, such as increased financial costs, improved aggregate strength, and reduced environmental impact, are not directly related to the effects of temperature control during testing. While improper testing can eventually lead to increased costs due to rework or material failure, the most immediate and direct consequence linked to temperature fluctuations is the inconsistency in test results.
