How Does Concrete Flow?
One of our BFI Consultants was sharing with me about the ice flows in Yosemite. He explained that when ice begins to melt it creates a slurry type substance that flows like concrete. He then made an interesting statement that "debris flows" are an even more effective analogy to displ
This video is a grahic display of "debris flow". Debris flow is a moving mass of loose mud, sand, rock, water, and air that travels down a slope under the influence of gravity. Sound familiar? Water, sand, gravel (aggragate) are all components of concrete.
Watch the video and get a feel of how concrete flows into place to form a concrete slab, or any other concrete structure that can be formed out of concrete.
As you watch the debris flow video think about how air temperature and water can affect the drying of the concrete slab. At BFI we are asked to visit sites where concrete cracking and other defects have occurred and many times the air temperature and/or amount of water that has contributed to the concrete to dry (set up) too quickly which can cause cracks or other defects.
Let it flow,
