ASTM C39/C39M-21 Compressive Strength of Cylindrical Concrete Specimens
ASTM C39/C39M-21 determines the properties of cylindrical concrete specimens. The method helps with the determination of the compressive strength of these cylindrical concrete specimens. The final results of this method are displayed keeping in view the international standards and inch-pound units.
ASTM C39/C39M-21 test method covers the characteristics of cylindrical concrete specimens. The shape and size of the specimen contribute to the calculation of its compressive strength. The method proceeds with the quality check, heat treatment, and the testing of the chemical composition of materials. The results obtained from this method help in quality control, research, mixing, and placing operations; determination of compliance with specifications; control for evaluating the effectiveness of admixtures and performance evaluation of various cylindrical concretes.
The method covers the application of a compressive axial load on the cylindrical concrete until failure occurs. The specimen must be kept moist and placed on the bearing block as per the standards specified. The load indicator is set to zero and the specimen is properly aligned. The load is applied continuously until a steady decrease is noted on the indicator. The compressive strength is calculated by applying the formula once the failure occurs.
Specimen size should be as per the requirements. In this case, the concrete should have a density of over 800 kg/m3 [50 lb/ft3].
The compressive strength of the specimen is calculated by dividing the maximum load attained during the test by the cross-sectional area of the specimen. F stands for the compressive strength and P stands for the maximum load.
ASTM C39/C39M-21test method is specifically important for the quality assurance and durability check of cylindrical concrete specimens. The top service provider in this regard is the Infinita Lab which ensures efficient and reliable testing.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 is a standard test method for the analysis of sulfochromate etches solution used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
