What are the new materials in civil engineering?
Lightweight concrete, self-compacting concrete, high-volume fly ash concrete, high-performance concrete, low-strength concrete
New energy-saving wall materials, new masonry materials, new composite wall panels, FRP composite materials, smart materials
Low-strength concrete This material can be used for foundation, pile filling, pad, isolation and for roadbed or filling holes can also be used for underground structures. In some specific circumstances, the use of low-strength concrete to adjust the relative density of concrete, work, compressive strength, elastic modulus and other performance indicators, and difficult to produce shrinkage cracks
1 High performance concrete (HPC) requires high durability and high strength, excellent workability, first reflected in the high early strength, high acceptance strength, high elastic modulus; followed by high durability. Can protect the steel is not corroded, used in other harsh conditions, the same can keep the concrete strong and durable; the last high ease of work, pumpability, easy to repair.
