Abstract

Concrete would be as the composition and supporting unsure on building structure. If the concrete is good quality, it can hold the building load such as dead load which is as the concrete load itself as well as life load which is one of loads that is used in making concrete is sand. In Merauke Regency, there are some local sand mining and import sand. This research intends to investigate the characteristic of concrete by mixing the local and import sand. The research is conducted in laboratory of Civil Engineering, University of MasamusMerauke. The methodology consists of design by using DoE method. The composition using in this research is 70% import sand (Palu) and 30% local sand; 80% import sand and 20% local sand, normal local sand and normal import sand. The research uses 20 cubes with the dimension of 15x15x15 cm as the samples. Result shows that the compressive strength on the composition of 70% Palu sand and 30% local sand is 21.80 Mpa; the composition of 80% Palu sand and 20% local sand is 29.54 Mpa; and the composition of local sand, normal concrete 16.57 Mpa; and Palu sand is 30.56 Mpa. The production is more than planned compressive strength such as more than K-225.
