The purpose of this study was to assess the physical and mechanical properties pavement concrete for rural roads South Korea made with air-cooled slag aggregate, which is an industrial byproduct. This assessed chemical according following performance requirements based on design criteria Ministry Agriculture’s Agricultural Production Infrastructure Maintenance Business Plan Expressway Corporati...

In recent decades, the use of self-consolidating concrete has become widespread. Hence, recognizing the various properties of self-consolidating concrete are essential. In this study, several mixture designs have been tested and final mixture design of crushed tile aggregates which were replaced by 0%, 25 %, 50%, and 100% volume percentage of natural aggregates were conducted. To evaluate fresh...

Concrete's drawback is its low tensile strength and heavy weight, which may exceed 2400 kg/m3. The significance of self-weight in building construction essential, particularly when dealing with seismic loads. larger the inertial force from weight structure itself, greater therefore lightweight concrete can provide an opportunity to lower own a smaller unit 1850 Fly ash was employed as substitut...

The influence of different silica fume content on the slump, expansion, compressive strength and flexural high-performance concrete was studied. results show that with increase content, strength, a trend increasing first then decreasing. optimal HPC(Highperformance concrete) is 3% to 6%.
