| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 97 === With the rising of environmental awareness and the consuming of the natural resources the issue of energy reuse has been gradually emphasized by the public. Therefore if we can find the alternative material we may be able to relieve the effect that brought by the problem. This research the coffee residue that usually is being regarded as the trash and fuel into the concrete mortar. Meanwhile this research observes the workability compressive strength setting timeESPI test hydration heat transfer. This research also uses the optical microscope to observe the major and minor difference to find out the best amount that should be added into mortar. By doing so this research discusses the feasibility of applying the ash of coffee residue.
Through the measurement and experiment by the research we find out to add 5% and 10% of coffee residue ash into the mortar is more feasible than others. Additionally after several experiment we also find out the gravel sand that has being added 15% and 20% the is lower. With the adding of the percentage the workability and the flow test will decrease comparatively and the crack inside the gravel sand. In addition the result of the compressive strength also shows that when the percentage of coffee residue ash adding increased the amount of absorbing will also rise comparatively. This will decrease the compressive strength. By an example of identical percentage we know that the longer we put the higher the compressive strength. We can also know from two examples of an experiment of compressive strength that respectively add the 600℃coffee residue ash and the 500℃coffee residue ash the 600℃samples compressive strength is better than 500℃ no matter comparing with duration and the percentage.
