Characteristics of Concrete With Rice Husk Ash Local Kutai Kartanegara

Abstract. Concrete material made from natural waste was developed to balance the use of concrete materials resulting exploration with an impact on environmental damage, rice husk is a mills and contains reactive silica has benefit reducing energy consumption in cement production. Laboratory test method form testing compressive characteristics used standard cube 150 mm x total sample 24 samples. The effect strength amount replacement 0%; 5%; 10% ; 15% which could be compared without using ash. obtained terms age 28 days. mechanical properties ash at days gave optimal results addition 5%
