ASTM C342 Potential Volume Change of Cement-Aggregate Combinations

ASTM C342 is a standard test method for the determination of volume change in cement-aggregate combinations. This test technique measures the linear expansion that occurs in cement-aggregate combinations in mortar bars when impacted by temperature and water saturation fluctuations during storage under specified test circumstances. ASTM C342 assesses the cement-aggregate interactions that might cause expansion, particularly when the cement has a low alkali concentration or is non-reactive to alkalis.

    Introduction to ASTM C342

    By measuring the linear expansion produced by the combinations in mortar bars, ASTM C342 measures the possible expansion of cement-aggregate combinations. To model possible volume changes in concrete construction, the temperature and water saturation of mortar bars are changed periodically. ASTM C342 studies the interactions between cement and aggregate by analyzing the expansion behavior of cement-aggregate combinations. It is done when the aggregate is thought to be nonreactive with alkalis or the cement has a low alkali concentration. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM C342 tests for our clients.  The test approach evaluates the possible behaviors of these combinations under different environmental conditions, which may help researchers and industry specialists better understand and predict possible volume changes in real applications. 

    ASTM C342 Test Methods

    Apparatus SetupContainers that can store corrosion-resistant material and removable sheet metal spacers that are used to support the specimens within the containers.
    Measurement of Potential Volume ChangeVolume change is measured by detecting the linear expansion developed by the cement-aggregate combinations in mortar bars. 

    ASTM C342 Test Specimen

    Specimen DetailsCement that meets ASTM C150 specifications should be selected. 3 pairs are made for each combination. The ASTM C227 protocol is used for molding mortars.
    Specimen PreparationThe specimen is cleaned before processing using ASTM C150.
    Specimen DimensionsDimensions should be as per the ASTM requirements.

    ASTM C342 Test Results

    ASTM C342 provides a way to assess the behavior of cement-aggregate combinations that may affect the performance of concrete buildings by monitoring the linear expansions. Micro-cracking impacts can also be discovered using this test. The results are helpful to industry experts working on concrete research and development.

    Tests Related to ASTM C342ASTM C342 is similar to ASTM C109, in which the compressive strength of hydraulic cement is measured by hydraulic cement mortars.
