Mortar and Cement testing equipment for strength, set time and mix evaluations
A variety of both laboratory and field tests are required to ensure that cement mixtures are reliable and created correctly. Much research and experimentation has been done to determine the composition, mixing techniques and precise testing essential to long-lasting structures.
Quality tests help to identify the usage of cement and mortar for different purposes based on its durability and performance. The elements examined create a well-rounded analysis of the specifications of a particular cement mixture. With these specifications, one is able to achieve the perfect cement.
Some cement and mortar laboratory tests include:
Strength Test – Because the strength of cement cannot be directly defined, it is indirectly defined by the compressive strength. This guarantees a strong and durable cement mixture.
Consistency Test – Vicat testing is used to determine the softening point of cement mixes. This analysis works to determine the standard consistency of the paste.
Fineness Test – The finesse of cement can be determined either by a sieve test of an air permeability test. This value is relevant to the mix’s rate of hydration, rate of evolution of heat as well as its rate of gain of strength.
Soundness Test – Cement often undergoes a large expansion after setting with can cause disruption to the set and hardness. Because of this, soundness tests are conducted in order to detect the presence of uncombined lime and magnesia within cement mixtures through either the Le-Chatelier or autoclave method.
Heat of Hydration Test – To ensure that the temperature during a cement mixture’s hydration process does not dramatically change, tests are done during the reaction. The heat of the solution is fist measured using a calorimeter after hardening for 7 days, and then again at the 28-day marker.
Tensile Strength Test – By adding direct force to a cement mixture, its ability to resist stretching or breaking when being pulled apart is able to be assessed. This test ensures that the cement is able to support the weight it will endure throughout its life.
Chemical Composition Test – Because the cement mixes require such carefully controlled portions, many different tests are conducted to determine that there is a correct chemical composition. These are essential to confirm the mix was properly produced and controlled.
The tests don’t stop here. Once in the field, additional tests are performed to further analyze both cement and mortar. These mostly inspect setting characteristics such as color, adulteration, the presence of lumps and the date of manufacturing. When finally ready to pour, concrete has undergone an extensive list of both lab and field tests. Although time consuming, each assessment is important to establish high-quality, long-lasting cement, and mortar mixtures.
