Abstract
Green materials can be defined as ‘eco-friendly’ materials. Materials which have less impact for environment, durable, and sustainable, can be categorized as green materials. Natural polymer modified mortar is one innovation that meets the purpose of green materials, because it is more durable and sustainable compared to conventional mortar. Since previous research of natural polymer modified mortar with Gracilaria Sp. and Moringa oleifera performed very good performance of compressive strength, this research then investigated its performance in aggressive environment that was represented by sea water and brackish water curing. This research wanted to find whether natural polymer modified mortar with Gracilaria Sp. and Moringa oleifera performed still perform good in aggressive environment or not. Mortar composition is of weight ratio of cement : sand : water = 1 : 1 : 0.6. Natural polymer modified mortar has compressive strength design of f’ c = 30 MPa (for mortar cured by plain water). There are 8 categories and 10 compositions for each category, A-H. Natural polymer of Gracilaria Sp. powder and grinded raw Moringa oleifera were added into mortar mix. The composition of Gracilaria Sp. and Moringa oleifera based of percentage of cement weight for each mix composition. Each composition was cured by three curing mediums: plain water, sea water, and brackish water. All specimens were tested for compressive strength at ages 7, 14, and 28 days. The result of the compressive strength showed that optimum compressive strength chieved by TK-0.2% - SW - H that consists 50% of Gracilaria Sp. and 50% Moringa oleifera, compared to control specimens. This research meets conclusion that natural polymer modified mortar consists of Gracilaria Sp. and Moringa oleifera performs higher compressive strength in aggressive environment compared to the plain mortar.
