<p>In the quest for sustainable solutions to environmental challenges, the exploration of alternative materials derived from by-products has gained considerable momentum. In the engineering industry, rice husk ash (RHA) stands out as a promising candidate to replace cement. It is an amorphous powder rich in silica that possesses pozzolanic properties similar to ordinary cement. Therefore, using RHA in concrete not only promises a means of waste management, but it also can potentially increase the performance of concrete. This study investigated the mechanical properties of specimens of mortar incorporating RHA as a partial replacement for cement. To properly assess the suitability of RHA for use in pavement, the hardness and slip resistance of specimens were also tested. The results showed that the particle size and loss on ignition of the RHA significantly influences the workability of mortar incorporating RHA. Some of the hardened specimens could achieve higher strength than the control specimen. However, increasing the RHA content from 10 to 20% led to a significant decrease in the strength and slip resistance of the specimens. Nevertheless, all RHA types used in the study developed sufficient flexural strength, satisfactory slip resistance and excellent hardness values, which makes them potentially safe and comfortable, both as road and pedestrian pavements. Finally, our analysis of the CO<sub>2</sub> emissions during production demonstrated that the use of RHA is less damaging to the environment than is cement.</p>

Study on Anchor Properties of Mechanical Anchor using Nut on Reinforcing Bar End

<p>The purpose of this study is the development of an RC joint structure for connecting precast PC slabs used for replacement of the deteriorated RC slabs of a steel girder bridge, wherein the anchor length of the reinforcing bar in the bridge span direction is shortened by using mechanical anchorage with a nut at an end of the bar. The applicability of that joint to actual bridge structures has already been confirmed by the moving wheel loading test. In this paper, the pull-out test is conducted on reinforcing bars with nuts at their ends to clarify the anchor properties, and the applicability of the existing bond-slip-strain relationship considering the behavior of the nut and the reduction of the effect of strain of reinforcing bar is confirmed.</p>
