Summary:The present invention relates to mortar using activated particulate material, the mortar having improved strength and workability and simultaneously reducing a use rate of cement by replacing a portion of the cement with activated paper ash, and according to the present invention, provided is mortar using activated particulate material, composed by mixing: mixed powder containing 10 wt% of desulfurized gypsum, 60 wt% of cement, 10 wt% of blast furnace slag, 10 wt% of fly ash, and 10 wt% of an activated particulate material; 250 wt% of sand, based on the mixed powder; and 65 wt% of mixed water, based on the mixed powder, wherein the activated particulate material is formed within the range of 8:2 to 9:1 of mixing ratios of the activated purified fly ash and the activated paper fly ash, the activated particulate material has a degree of fineness of 6000-8000 cm2/g, and the activated paper fly ash is formed in a weight ratio of 9:1. La présente invention concerne du mortier utilisant un matériau particulaire activé, le mortier ayant une résistance et une aptitude au façonnage améliorées et réduisant simultanément un taux d'utilisation de ciment en remplaçant une partie du ciment par des cendres de papier activées, et selon la présente invention, l'invention concerne un mortier utilisant un matériau particulaire activé, composé en mélangeant : une poudre mélangée contenant 10 % en poids de gypse désulfuré, 60 % en poids de ciment, 10 % en poids de laitier de haut fourneau, 10 % en poids de cendres volantes et 10 % en poids d'un matériau particulaire activé ; 250 % en poids de sable, par rapport à la poudre mélangée ; et 65 % en poids d'eau mélangée, par rapport à la poudre mélangée, le matériau particulaire activé étant formé dans une plage de rapports de mélange des cendres volantes purifiées activées et des cendres volantes de papier activées de 8:2 à 9:1, le matériau particulaire activé a un degré de finesse de 6 000 à 8 000 cm2/g, et les cendres volantes de papier activées sont formées selon un rapport pondéral de 9:1. 본 발명은 시멘트 일부를 활성 제지 애쉬로 대체하여 시멘트의 사용 비율을 감소시키는 동시에 강도 및 작업성이 개선되는 활성 분체를 사용하는 모르타르에 관한 것으로, 본 발명에 따르면, 탈황석고 10wt%, 시멘트 60wt%, 고로 슬래그 10wt%, 플라이 애쉬 10wt%, 활성 분체10wt%를 포함하는 혼합분말; 상기 혼합 분말에 대해 외할로 모래 250wt%; 및 상기 혼합 분말에 대해 외할로 혼합수 65wt%를 혼합하여 조성되고, 상기 활성 분체는 활성 정제 플라이 애쉬와 활성 제지 플라이 애쉬의 혼합비율이 8:2 내지 9:1의 범위내에서 구성되고, 상기 활성 분체는 6000 내지 8000cm2/g의 분말도를 가지는 것을 특징으로 하는 활성 분체를 사용하는 모르타르가 제공된다. 활성 제지 플라이 애쉬가 9 : 1의 중량비로 구성되는 것을 특징으로 한다.
