quality control

Concrete Material Testing Before concrete pouring, concrete from mixers are being tested by a method called slump test, when the concrete is PumpCrete Design (PCD), Bored Pile Mixed (BPM), or spread test, when the concrete is designed as Self Compacting Concrete (SCC).  Slump or spread test is where you are determining the consistency and quality of concrete to water ratio. After passing this test, the sampler will provide you a cylinder where the concrete sampled is to be retained for compressive strength testing after 7, 14 and 28 days. (Note: 28 Days - the concrete will achieve its maximum [...]
