No further reproductions authorized. The surface of the unit in contact with the grout specimen shall not have been previously used to mold specimens. Place nonabsorbent blocks, cut to proper size and of the proper thickness or quantity, at the bottom of the space to achieve the necessary height of specimen.
New lining material shall be used for each specimen. NOTE 6—The lining, such as paper towel, is used to aid in stripping the grout specimen from the mold. Proper installation of the lining prevents irregularly sized specimens and varying test results.
Such approval shall be based on comparative testing of grout specimens constructed from molds as described in 6. Approval shall be limited to a cause retardation of cement. In order to prevent this from occurring, new single specimen shape, method of forming, masonry units wooden blocks shall be soaked in limewater for 24 h, sealed with varnish used, and grout mix.

The concept of putting 11" slump gout into a non-absorbent mold will yield meaningless results regarding the performance of the structure and the results should be rejected.
All of the current code standards are based on the grout testing method that have be used as documentation of the grout for decades of testing and research because it provides the most realistic measure of properties. Keep in mind that gout is one component in a structural element the wall and is not like a test of delivered concrete in cylinders made from placed concrete that is the main building component. In masonry, the grout strength is not that important, since its purpose is to transfer the loads from the wall into the reinforcement usually and the grout strength should be approximately the strength of the net unit strength.
Grout should not be used to increase the vertical strength of a wall, but is intended to transfers loads between the masonry units and the reinforcement if needed.
Masonry Grout Testing? ASTM C1019
You may have at least heard of this standard by now, but maybe you don't know much about it. What are the benefits?
Let's take a closer look. Your customers can view this accreditation listing and will likely use it as a method of determining whether or not you are competent to perform a given task.
So, it makes sense that your laboratory also has a policy for ensuring the competency of the subcontractors and vendors that you use. Seven Steps for a "Perfect" On-Site Assessment We all realize that having a perfect on-site assessment is no small accomplishment. However, there are some rather simple steps your laboratory can take to ensure that the assessment runs smoothly and relatively error-free.
The staff at AASHTO re:source understands what a special event the on-site assessment is for each of our customers, and that it can be an overwhelming process. The goal of this article is to give you a few pointers on preparing for your on-site assessment.Measure and record the height of each face at midwidth.
Keep the top loss. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Or at least they should.
