A Study on the Bending and Compressive Strength of Mortar using Waste Calcium Material as a Filling Material

폐칼슘 재료를 채움재로 사용한 모르타르의 휨·압축강도에 관한 연구

Oyster shells are difficult to grind, while oyster shell powders have coarse and coarse grains, whereas egg shell powder, the same high calcium material, has small and soft particles and has opposing properties. In order to study the change in flexural and compressive strength by designing different mixing ratios using 50% of oyster shell powder and egg shell powder as a filling material. As a result of the experiment, there is almost no difference in the result.
