ASTM C94/C94M-21b test method determines the properties of ready-mixed concrete. The ready-mixed concrete is manufactured as per the purchaser’s demand and checked for its quality. The final results of this method are displayed keeping in view the international standards and inch-pound units.
Scope:
ASTM C94/C94M-21b test method covers the quality requirements of ready-mixed concrete. The uniformity properties of various materials are determined, and their application is decided. The results aid in the research, quality check, performance evaluation, and improvement of the materials. The method is intended to ensure effective performance and durability.
Procedure:
The dimensions of the specimen are determined, and the specimen undergoes testing depending upon the pre-determined tolerance level. The method covers the central-mixed concrete, shrink-mixed concrete, and truck-mixed concrete. The results are recorded, evaluated, and documented as per the globally accepted standards. The method also covers the packaging and certification.
Specimen Size:
Specimen size should be as per the requirements. In this case, each sample consisting of approximately 0.1 cubic meters shall be taken after discharge of approximately 15 % and 85 % of the load.
Data:
The density of each sample is calculated by applying the formula where D stands for Density, M for Mass, and V for Volume.
Conclusion:
ASTM C94/C94M-21b test method is specifically important for the quality assurance and durability check of ready-mixed concrete.

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.
