Research on the early strength growth characteristics of reinforced concrete pavement in Hexi region
In order to study the growth characteristics of early strength of reinforced concrete pavement in Hexi re-gion,this article takes the construction of reinforced concrete pavement in the new project of G30 Lianhuo expressway Suzhou service area as the research object,and obtains concrete strength values from 40 measurement areas through on-site measurement for statistical analysis.The results show that the early compressive strength of reinforced concrete pave-ment increases rapidly,reaching 84.4%of the design strength on the third day and 98.34%of the design strength on the seventh day after concrete pouring is completed;75%of the test areas can reach the design strength of concrete within 7 days,and 90%of the test areas can reach the design strength of concrete within 9 days.Studying the growth characteris-tics of early strength of reinforced concrete pavement can provide guidance and suggestions for the construction of rein-forced concrete pavement,and can minimize the occurrence of cracks in reinforced concrete pavement.
