22 Αυγ 2023 · This test method covers determination of the density of freshly mixed concrete and gives formulas for calculating the unit weight, yield or relative yield, cement content, and air content of the concrete.
21 Απρ 2020 · ASTM C138 - Density of Concrete. This video provides a summary of test method procedures. For more information on this method, including calculations, please visit the CTTP online training...
This document specifies procedures for testing fresh concrete. It specifies the following test methods: determination of consistence (slump test, Vebe test, degree of compactability, flow-table test for high‑fluidity concrete, and the slump-flow test), determination of fresh density and determination of air content by the pressure-gauge ...
8 Ιουν 2024 · The ASTM C138 test is crucial in concrete unit weight theoretical density measurement, as it enables the determination of the density of freshly mixed concrete and provides formulas for calculating the unit weight, yield, cement content, and air content of the concrete.
This document specifies methods for testing the density and depth of water penetration of hardened concrete.
AASHTO T121 is a standard test method used to determine the density (unit weight), yield, and air content of freshly mixed concrete. This test is essential for quality control in concrete production and construction, ensuring that the concrete mix meets the specified requirements for strength, durability, and workability.
