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. With these many tests come a variety of cement testing equipment.
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.
In order to assure fast and accurate results, proper cement and mortar testing equipment is needed. These tools should meet ASTM and AASHTO specifications and be from a reliable manufacturer. 这里是洪堡工厂., we provide the highest quality equipment that works to make the testing process better for everyone. We provide world renowned equipment for all of your cement testing needs.
Some cement and mortar laboratory tests we cater to include:
强度试验—— 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.
一致性测试—— Vicat testing is used to determine the softening point of cement mixes. This analysis works to determine the standard consistency of the paste.
细度测试—— 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.
健全性测试—— Cement often undergoes a large expansion after setting with can cause disruption to the set and hardness. 正因为如此, 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.
水化热试验 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.
抗拉强度试验- 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.
测试不止于此. Once in the field, additional tests are performed to further analyze both cement and mortar. These mostly inspect setting characteristics such as color, 掺假, 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. 虽然耗时, each assessment is important to establish high-quality, 持久的水泥, 和砂浆混合物.
