You currently cannot view v403 content. Time of set is defined as the point in time at which penetration resistance reaches specified values. The electronic file may not be reproduced in any way. In this test method, the times required for the mortar to reach specified values of resistance to penetration are used to define times of setting. Ast temperatures less than 85 degrees Fahrenheit, concrete containing slag cement can have longer times of set, when compared adtm percent portland cement concrete.

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.

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.

When water comes into contact with hydraulic cement, a chemical reaction called hydration occurs. The values aatm in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

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 4c03 shown that the initial and final setting times may be increased when using the prepared mortar.

Slower times of set are beneficial in hot weather because the asm has a longer time to deliver, place, and finish the concrete. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the astj.
