This reaction combines water with cement forming chemical compounds, increasing the strength of the material and changing it from a plastic, moldable material to a solid capable of withstanding substantial loads. No items in cart.

However, when the setting time of concrete is desired, the test shall be performed on mortar sieved from the concrete mixture and not on a prepared mortar intended to simulate the mortar fraction of the concrete; it has been shown that the initial and final setting times may be increased when using the prepared mortar.

The electronic file may not be reproduced in any way. However, replacement rates of less than 30 percent generally will not affect times of set significantly. The resistance of the concrete mixture to penetration by standard. There were no books found for the applied search filters.

ASTM C identifies initial and final time of set as: No further reproductions authorized. Why is Time of Set Significant? When water comes into contact with hydraulic cement, a chemical reaction called hydration occurs.

In this test method, the times required for the mortar to reach specified values of resistance to penetration are used to define times asttm setting. Register satm a trial account. Among other things, the initial and final time of set are influenced by:
