Abstract


Polymer modified concrete is one concrete technology innovation to meet the need of strong and durable concrete. Previous research found that found that Moringa oleifera can be applied as natural polymer modifiers into mortars which increased their compressive strength significantly. In this resesearch, Moringa oleifera has been added into concrete mix for natural polymer modified concrete, based on the optimum composition of previous research of natural polymer modified mortar. The research will find if there any increase of compressive strength of polymer modified concrete with Moringa oleifera as natural polymer modifiers. There were 3 compositions of natural polymer modified concrete with Moringa oleifera referred to previous research optimum compositions of natural polymer modified mortar with Moringa oleifera. Several cylinder of 10 cm x 20 cm specimens produced and tested for compressive strength at age 7, 14, and, 28 days. The research meet conclusions: (1) Natural polymer modified concrete with Moringa oleifera, with and without skin, has higher compressive strength compared to natural polymer modified mortar with Moringa oleifera and also control specimens; (2) Natural polymer modified concrete with Moringa oleifera without skin is achieved by specimens contains Moringa oleifera as 0.2% of cement weight; and (3) The compressive strength increase of natural polymer modified concrete with Moringa oleifera without skin is about 168.11-221.29% compared to control specimens.
