Deskripsi :

Nowadays, concrete deterioration has become a major problem throughout the world.One ofthe actorsthatcontribute to the deterioration of concrete is Alkali-silica reaction (ASR). ASR will occur when these components such as reactive silica, alkalis, and sufficient moisture are present in concrete (ACI 221.1R-98).
Several ways have been applied to control or even stop ASR in concrete: such as utilization blended cement, cement with low alkali content, innocuousaggregate, control of total alkali in concrete. Currently, it is generally accepted that supplementary cementitious materials (SCMs) such as fly ash (FA), silica fume (SF), blast furnast slag (BFS), are typical SCMsused in concrete. SCMs have been used spreadly and successfully to mitigate ASR. This experimental program wascarried out in the laboratory to investigate the effectiveness of mineral and chemical admixtures in order to reduce expansion. The production of mortars and concrete are included in this study. The pessimum proportion of aggregate is determined when reactive and non reactive aggregates were mixed with the ratio of 30:70. Concrete prisms were made according to RILEM AAR-3, and mortar prism were made based on JIS A 1146. Concrete specimens were cured under 40oC, and R.H. 100% for expansion test. Meanwhile, mortar specimens were also treated under 40oC, and R.H. 100% for expansion measurement.
