Construction Specifications Institute, Inc. The values obtained can be used to verify that the consistency of each batch of mortar is the same. This test method covers procedures for the sampling and testing of mortars for composition and for their plastic and hardened properties, either before or during their actual use in construction. The test is performed by obtaining a representative dry sample of mortar mix from the job site and performing a series of calculated measurements in the laboratory.

There were no books found for the applied search filters. Currency display settings. It includes methods for verifying the mortar mix proportions, comparing test results for field mortars to preconstruction testing, and determining batch-to-batch uniformity of the mortar.

Compressive Strength Compressive strength tests of mortar prepared in the field reflect approximate mortar strengths. Prices subject to change without notice. Students Click Here Join Us! It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

With over years of production history, the automotive industry has been at the forefront of manufacturing technology since its inception. This test is of particular importance in evaluating mortars that contain air-entraining portland cement, air-entraining lime, masonry cement or any combination thereof. Requirements concerning the renovation of uncoated areas remaining after initial hot-dip galvanizing are contained within the applicable material specification.

Addison-Wesley Publishing Co. This quantity of water is not sufficient to produce mortar with a workable consistency suitable for laying masonry units in the field. Deutsches Institut fur Normung E. The purpose of the testing is to determine whether a mortar mixed with construction materials to specified proportions conforms with physical property requirements listed within the standard. Association Connecting Electronics Industries.

Repetitive testing using these test methods on consecutive or intermittent batches provides a method for measurement of batch-to-batch variations in the mortar production. Builders Hardware Manufacturers Association, Inc. American Petroleum Institute. International Organization for Standardization. Aerospace Industries Association.

This practice can also be used to repair hot-dip galvanized coatings damaged by excessively rough handling during shipping or erection. Northern Marianas Islands.

However, these two aspects of aerospace machining can conflict, as manufacturers strive to maintain machining efficiency with new materials by using new methods and cutting tools. American Industrial Hygiene Assn. Detail Summary View all details.

Mortar samples are prepared in job site conditions. However, the sieving operation utilized during this test is not capable of separating an individual cementitious material when more than one material is used. These properties are influenced by mix proportions and ingredients, weather conditions, effects of chemical additives, and mixing time. You can also specify an in-place load test using a flat jack and jacking upward against completed masonry. If inconsistencies between preconstruction mortar composition and on-site mortar composition exist, immediate corrective action to modify mortar batching and mixing can be introduced.

Procedures for measuring properties of hardened mortars, such as compressive strength, are also defined. Consistency The consistency of field mortars is an indicator of batch-to-batch variations in mix materials and mixing time. Preconstruction testing and evaluation of mortar allows for comparisons of mortar produced in the laboratory to those mixed at the job site. However, the information obtained through this testing should be used to modify the consistency of mortar mixed in the field and not to condemn a mortar based on previously obtained results. Variations in the measured compressive strengths of field-sampled mortar and between the measured compressive strengths of construction and pre-construction mortar samples should be expected.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Field testing and sampling of mortar is used to verify consistency of materials and procedures, not mortar strength. Remember me for one month. Copyright Compu-tecture, Inc.
