theoretical calculationA theoretical calculation method of the axial compressive strength of a high strength concrete with fibre reinforced plastics (FRP) constraint is proposed. It is shown by test verification that the FRP strength devotion factor used for this method is in accord with actual ...
The purpose of the present study is to examine the effect of the type and volume fraction of coarse aggregate and the water-cement ratio of matrix on the confidence-limit of the compressive strength of concrete estimated by various non-destructive testing methods. Two series o...
Compressive strength of concrete is one of the most important elements for an existing building and a new structure to be built. While obtaining the desired compressive strength of concrete with an appropriate mix and curing conditions for a new structure, with non-destructive testing methods for ...

Furthermore compressive strength of concrete was evaluated for different weight ratios of added RSF. Significant results were obtained regarding compressive strength of concrete by incorporating nano SiO2 into the concrete. Furthermore, the results of compressive strength of the specimens reinforced by RSF...

The first describes experiments and the second presents a model to accurately predict the compressive strength of concrete columns confined by composite materials. FRP is wrapped around concrete columns and RC columns to determine the difference between their behaviors under uniaxial compression. ...
摘要: This paper addresses waste disposal through recycling; tile chips, crushed scallop shells, or crushed roofing tiles were mixed into concrete, and compressive strength was tested. The experiment was carried out in three parts. Series 1 measured the compres关键词:...
Surface texture was the most important aggregate property influencing concrete compressive strength. Because the aggregate strength was generally greater than that of the concrete and differences in the water-absorptive capacities of the aggregates were small, no relationship was found between the strength...
