A TALK ON THE DEVELOPMENT TENDENCY OF NEW ERA CONCRETE STRENGTH THEORY

摘要

With the purpose of changing the vibration and deterioration of long period properties and strength of concrete caused by materials used and the coarseness of technology, the multi-subject technological renovation is suggested to accelerate and bring into effect the orderly match and optimum of multi-layer, when it is in the course of continuous hydration, so as to realize steady increase of strength and avoid or delay its degeneration. Manage to control the increasing sequence of design loads; to adapt the damage threshold function; to explore capable-of-make-up strength composition structure which enable the loading capacity and life to strengthen simile tenuously with the economic construction. The concrete strength theories turn from losing stabilization out of crack development to continuous hydration and superposition of strengthening in load; to put to use the late period tremendous and steady strengthening latency of concrete; to avoid damage; it is the economic, safe, operable, continuously developable direction.
