ASTM C1437
Full Name
ASTM C1437 – Standard Test Method for Flow of Hydraulic Cement Mortar
Scope
ASTM C1437 outlines a standardized procedure for determining the flow of hydraulic cement mortars. This test is often used to assess the consistency of mortar and ensure it has the right workability for specific applications.
The scope of ASTM C1437 includes:
- Flow determination: the primary purpose of the test is to measure the flow of hydraulic cement mortar, which is the increase in the average diameter of the mortar sample after it has been dropped a specific number of times on a flow table.
- Mortar types: the standard covers hydraulic cement mortars, as well as mortars containing other cementitious materials besides hydraulic cement.
- Test apparatus: it specifies the apparatus required for the test, including a flow table, flow mold, tamper, trowel, and caliper.
- Test procedure: it provides a detailed step-by-step procedure for conducting the flow test, including mixing the mortar, filling the mold, tamping the mortar, dropping the flow table, and measuring the diameter of the spread mortar.
- Calculations: it outlines the formula for calculating the flow of mortar, which is expressed as a percentage increase in the average diameter compared to the original diameter.
- Significance and use: the standard explains the significance of the flow test in evaluating the consistency and workability of mortar, and its importance in various applications where specific flow properties are required.
In essence, ASTM C1437 provides a standardized and reliable method for measuring the flow of hydraulic cement mortar. This information is valuable for quality control in mortar production, ensuring that the mortar meets specified flow requirements for different applications.
