摘要:... The empirical models were developed to predict the performance of the GPB samples through the verification of the water absorption and compressive strength. The results showed that an optimum performance of GPB sample is predicted for the NaOH/Na 2 SiO 3 ratio range of 0.4 to...

摘要:... Eventually, all specimens are tested for compressive strength for 90 days. The experimental results show that the reduction of compressive strength depends on the corrosion percentage and stirrup diameter. According to this conclusion, a new formulation is proposed to express...

摘要:In order to investigate the internal curing effect of recycled brick aggregate (RBA) in recycled aggregate concrete (RAC) and calculate its contribution to the final compressive strength, two RAC groups with different recycled aggregates and 6 replacement ratios ( r ) under 4...

摘要:Is the variation in the compressive strength of concrete across the thickness of horizontally cast elements negligibly small or rather needs to be taken into account at the design stage? There are conflicting answers to this question. In order to determine if the compressive strength...
