-Mortars and grouts:
-* may be remixed but will not be retempered or used after they have begun to set.
-* will be used only when the materials being mortared or grouted are at a temperature of 40°F (5°C) or higher and will remain so for the duration of the required curing period.
-{{top}}
-===Mixture Requirements===
-====Standard Mortars and Grouts====
-The cement and fine aggregates will be proportioned by weight for batches of 1 cubic yard (1 m<sup>3</sup>) or more, and by weight or volume for smaller batches.  '''''Table 702-1''''' gives the mix proportioning information for standard mortars (R-2 & R-3) and grout (R-1).  Water is added in amounts necessary to obtain the consistency required for the work.
-{{top}}
-====Non-shrinking Mortar and Grout====
-Nonshrinking mortar and grout will not be used in contact with prestressing tendons or other highly stressed steel.
-Type H-1 (Non-metallic)
-* Used for dowels and anchor bolts.
-* Will be a premixed material.
-* The material selected will be from the Qualified Products List.
-* Water will be added in amounts necessary to obtain a mortar or grout consistency required for the work.
-{{top}}
-====Expansive Grout, Type E-1====
-Expansive grout, Type E-1, is used for filling the void around post-tensioned tendons in precast concrete box beams.  The grout will be proportioned as follows:

-====Requirements:====
-No sand will be used in the grout mixture.
-The grout will attain a 28-day minimum compressive strength of 3000 psi (25 MPa), according to ASTM C 942, but the grout will be proportioned by these specifications.
-The expansive admixture, including any plasticizing or water reducing agent, will not contain chloride ions &gt;0.50 percent by admixture weight nor any fluorides, sulfides, nitrates or thixotropic additives.
-The admixture may be in liquid or solid form.
-Aluminum powder of the proper fineness and quantity, or other approved gas evolving material that is well dispersed throughout the admixture, will be used.
-The grout will have an unrestrained expansion of 5 percent to 10 percent, according to ASTM C 940, except that the grout will be proportioned by these specifications and the expansion will be determined at three hours.
