PERILAKU KEKUATAN TARIK ENGINEERED CEMENTITIOUS COMPOSITE YANG DIPERKUAT SERAT MIKRO SINTETIS

Concrete has its characteristic as compressive strength but brittle due to its low tensile and flexural strength. Engineered cementitious composite (ECC) could overcome the shortcomings of conventional concrete by adding a type of synthetic microfibers, namely polypropylene fibers. This study analyzing the effect of adding polypropylene microfibers on the tensile and flexural strength and behavior of ECC. The fiber percentage variations are 0%; 0.75%; 1%; and 1.25% of the specimen volume with characteristic compressive strength of 20 MPa. The composition of cement, sand, nanosilica, water, and superplasticizer for 1 m^3 ECC is 320 kg, 226 kg, 96 kg, 144 kg, and 3.52 kg, respectively. Cylinder specimens of 15 x 30 cm were used for the split tensile strength test and beam specimens of 10 x 10 x 50 cm for flexural (modulus of rupture) test. The results of the split tensile strength test of ECC with 0.75% polypropylene microfibers (3.18 MPa); 1% (3.11 MPa); and 1.25% (3.31 MPa) were not significantly different from normal ECC (3.29 MPa). The results of the flexural strength test of ECC with 0.75% polypropylene microfibers (5.69 MPa), 1% (5.29 MPa), and 1.25% (5.40 MPa) increased significantly compared to normal ECC (4.49 MPa). The failure pattern showed a decrease in the number and size of cracks, indicating a more ductile behavior in both split tensile and flexural tests with the addition of polypropylene microfibers.
