摘要: Most concrete specifications tend to be prescriptive in nature and this can prevent producers from optimizing their mixtures for local materials, confuses the responsibility in-place performance of a structure. While it is generally agreed that superior way specify since should clarify responsibilities allow innovation, many parties construction are leery adopting specifications. One major concerns related lack adequate tests specification limits relate field performance. current test methods far perfect, thought there sufficient experience use them adoption will lead development better methods.
