Additionally, the method controls the flow of a second fluid into the box thereby circulating the first fluid to substantially eliminate temperature stratification of the first fluid in the box. Thus, the method provides a controlled environment for curing the specimen....
c test method concerned. NOTE 5—When molds in SI units are required and not available, equivalent inch-pound unit size mold should be permitted. 5.1.1 Cylindrical specimens for tests other than creep shall be molded and allowed to harden with the axis of the cylinder vertical. 5.1.2 ...
Different methods have been developed to evaluate the quality of concrete caissons. Apart from general concrete tests (concrete cylinder samples, and slump test), different non-destructive testing (NDT) methods can be used to evaluate the quality and reliability of concrete piles. These test can h...
A full factorial experimental design was used to investigate the effects of the following variables on cylinder strength: end preparation (sulfur capping versus grinding), cylinder size (100 versus 150 mm diameter), type of testing machine (1.33-MN capacity versus 4.45-MN capacity), and nominal ...
IR-06-01 The Effect of Test Cylinder Size on the Compressive Strength of Sulfur Capped Concrete Specimens Pre..
In this study, simple flexural strength tests by cylinder specimen that commonly used to compressive strength tests are executed to find the factors playing into the horizontal construction joint such as green cutting and curing methods for old concrete and properties of bedding mortar. Results show ...
24、, molding methods and methods of using the same actual officer.1.1.5 cylinder specimens are made in accordance with the relevant regulations.1.2 concrete specimens shall be fabricated in accordance with the following procedures:1.2.l sampling or mixed concrete mixture should be at least three ...
The upward reaction is transmitted to the cross girder of the frame through two 500 kN hydraulic cylinders attached to the cross girder, each cylinder is equipped with threaded adjustment and an end ball bearing to permit rotation. At the beginning of the test, the ends of the specimens were...
standard cylinder molds equipped with tamping rods as per ASTM C 31-09 were employed to prepare cylinder blocks for compression testing. Molding requirements were selected in accordance with ASTM C 31-09, and curing was conducted as per the guidelines outlined in ASTM C 31-0913. In total, six...
Splitting alongside failure cones indicated that the platens of the test apparatus did not provide friction to restrict lateral expansion near cylinder ends. Further, failure modes observed in high-strength specimens were more explosive as compared to their counterpart in low-strength specimens, and a...
