To　find　the　relationship　between　macro　and　micro　performance　of　cement　concrete,　an　experiment　for　testing　indoor　durability　of　cement　concrete　was　designed.　It　simulated　the　comprehensive　effects　of　multiple　deterioration　elements　in　a　natural　environment.　There　are　four　deterioration　factors　that　are　usually　borne　by　transportation　infrastructure:　dry　and　wet　cycling,　chlorine　salt　erosion,　carbonization,　and　freeze　and　thaw　cycling.　The　micro　and　macro　performance　indexes　were　tested　separately,　the　term　of　relative　change　rate　was　put　forward　and　the　calculation　method　for　the　index　of　the　relative　change　rate　was　given.　Based　on　the　analytic　hierarchy　process(AHP),　normalization　and　grey　correlation　theory,　the　degree　of　association　between　micro　and　macro　performance,　and　the　influence　weight　of　pore　structure　on　macro　performance,　were　calculated.　Finally,　a　quantitative　relation　model　was　established　between　macro　performance　change　and　micro　pore　structure　performance　change.　The　variability　in　macro　performance　of　concrete　can　be　calculated　from　the　variable　quantity　of　micro　parameters　according　to　the　model.　©　2015,　Editorial　Department　of　Journal　of　HEU.　All　right　reserved.
