Why use 150mm size cube for testing ?

2016/4/2If you use cube of size 300 mm, the load required becomes 2970 KN which is practically not possible because to crush the respective cube we require 3000 KN/ 300 ton capacity machine. When the applied load is much more, the additional safety factor needs to be increased because when the cube fails under such loads, it may hit anything in room with bullet speed. Get price

Calculating Density

2020/6/19Density is a fundamental concept in the sciences; you will see it throughout your studies. It is used quite often in identifying rocks and minerals since the density of substances rarely changes significantly. For example, gold will always have a density of 19.3 g/cm 3; if a mineral has a density other than that, it isn't gold. Get price

Symptoms of a Bad or Failing Fan Clutch

While many newer vehicles now use electric cooling fans to keep the engine cool, many older vehicles used a mechanical fan clutch to control the fans. The fan clutch is a thermostatic device, which means it operates based off temperature, and is usually mounted on the water pump, or another belt driven pulley. Get price

Cube Testing The cubes are generally tested at 7 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first. Get price
