| dc.description.abstract | Luced up paddy is the waste of rice drill. Luced up paddy consist on much amorf of silica if it's heated until 500-700" C of temperature in 1 to 2 hours. In this research, have used silica amorf as an additive thing in mortar mixture. The test material are made with composition to make on 1 cement: 2,75 sand: 0,5 water to make normal mortar. By adding amorf of silica directed by luced up paddy with variation mixture is 3 %, 6%, 9 %, 12 % and 15 % from the mount of cement to make normal mortar. The result of the researching to indicate the used of Silica amorf directed by incediarism luced up paddy with proportion 9 % will increase compressive strenght mortar up to 31,08% and will increase pull strenght up to 42,55% from normal mortar. While percentace of mortar will also smalles water absorbtion and porisity up to 2,504 % and 4,000% from normal mortar. | en_US |
