- The concrete structure has become the most popular construction around the world because of its strength, durability, and low environmental impact. In term of durability, concrete gives positive contribution in environmental revitalization, especially the green concrete. The green concrete is basically supported by green materials. Several researches have proved that natural materials can be defined as green materials because its advantage. This paper meets conclusions: (1) Natural pozzolan such as Trass Muria Kudus, natural fiber such as coconut fiber, and also natural admixtures such as sugar and sugar cane liquid have ability to achieve higher performance of concrete, therefore the use of natural materials for green concrete is necessity; (2) The optimum value compressive strength for specimen with Trass Muria Kudus is 29.802 MPa, 51.27% higher than plain specimen; while splitting tensile strength for specimen is 2.975 MPa, 34.99% higher than plain specimen; and elastic modulus is 9176.466 MPa, 9.68% higher than plain specimen; The maximum splitting-tensile of concrete with coconut fiber is 4.339 MPa for fiber length of 80 mm. It is 13.62% higher than plain concrete; and (4) The dosage of sugar and sugar cane liquid admixture of 0.03% by weight of cement can perform as retarder while the dosage of 0.3% by weight of cement as accelerator.
