水泥立方测试

立方体测试

The cement cube test is used to determine the compressive strength of 液压水泥 和 other mortars. This quality is very important for almost all cement 和 mortar applications, especially when relating to infrastructure. Because compressive strength plays such a large role in cement mortar functionality 和 success, many different tests are used to analyze this characteristic. The test results can then be used to determine compliance with specifications, such as ASTM C109 和 ASTM C780. These 和 similar ASTM test methods emphasize the importance of using care in closely observing the testing procedures used to verify requirements.

Masonry mortars composition can include the following cementitious materials: Portl和 cement, 液压水泥, 砌筑水泥, 矿渣水泥, 生石灰, hydrated lime 和 lime putty. 总s may consist of natural or manufactured s和. Admixtures may also include accelerators, water repelling compounds, 色素沉着, retarding 和 air entrainment solutions.

Cube testing is one of the most simple 和 common ways to determine the compressive strength of cement 和 mortar mixes. 要执行此测试, the mixes are poured into cube molds 和 tempered for 24 hours to ensure no voids are present. Once prepped, the surfaces are smoothed with cement paste. One to three weeks after curing, specimens are placed in compression testing machines where a load is gradually applied until the mix fails. To ultimately calculate the resulting compressive strength, the load at the failure is divided by the area of the specimen.

Masonry structures are constructed to be load bearing, including walls, columns 和 foundations. Determination of the compressive strength is critical in ensuring the structure can support a given load.

洪堡 offers a variety of cube molds for testing, which are constructed of brass, stainless steel 和 plastic. All are 3-gang molds 和 can be purchased in diagonal 和 parallel configurations. Some models f或使用 with expansive grouts feature a detachable base 和 top plate for ease of use. A briquette mold for 液压水泥 mortar tensile strength tests is also available.

同样可用的还有 夯棒 for tamping material into the cube molds, as well as 和 卡尺 for smoothing 和 recording sizes of cubes before compression testing. 我们携带 2-inch cement cube pad retainer caps 和 压缩垫 for securing cubes during compression testing.
