Abstract

As the world becomes more complex and people become more evolved the desire to build taller building and design more complex structures is on the rise. The major problem that occurs with larger structures are the forces associated with building bigger. One way to help solve the problem of large stresses in concrete structures is to include more reinforcing steel and design more complex reinforcing configurations. The down side to increasing the amount of reinforcing steel is that the steel creates smaller gaps for the concrete to flow through. This problem was realized in the early 1980’s and the concept of producing concrete that flows like water was brought to life, this product was called self-compacting concrete. This research will look at the plastic properties associated with the fresh properties of self-compacting concrete to ensure that the mixes have the correct flowability while maintaining its structural integrity. Also, the amount of entrained air could ultimately decide how well the structure functions in different environments. If all tests are successful and the mix is approved the material should flow through the formwork without assistance and have a proper air structure along with evenly distributed aggregate. This research shows that a material can be very fluid, but still exhibit the strength of normal concrete.
