The powder and liquid components were thoroughly mixed in a mixer for 30 seconds, and then transferred to a BD 3 ml syringe. The syringe was then placed in a custommade rig and the cement was extruded using a universal materials testing machine (Shimadzu, Kyoto, Japan) at a displacement rate of 3 mm/min. The measurement was stopped when the load reached 200N. The working time of each cement sample was analysed taking the start of mixing as time point zero.
Universal materials testing machine
Manufactured by Shimadzu
Sourced in Japan
The Universal materials testing machine is a versatile laboratory instrument designed to evaluate the mechanical properties of a wide range of materials. It can perform various tests, including tensile, compressive, flexural, and shear tests, to determine the strength, stiffness, and other characteristics of materials.

Eight specimens (12mm in height and 6mm in diameter) were tested in compression, as stipulated in ASTM F451-08 standard 18 . The specimens were left to set in the moulds for 1 h and then taken out and stored at T = 21 ± 1 °C for 24 h. Finally, the specimens were tested using a universal materials testing machine (Shimadzu, Kyoto, Japan) at a displacement rate of 20mm/min.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
