As the progress of using materials for making concrete is growing, a lot of research has been done to make concrete with a variety of materials to get concrete performing well. The compressive strength and split concrete are influenced by what materials are used. This study conducted an experiment to make fibrous concrete using a mixture of fiberglass material type Chopped Strand Mat (CSM), CSM was cut to a size of 1 cm x 4 cm then CSM was described by pulling CSM from the webbing. The cylindrical specimens measuring 150 mm x 300 mm, the compressive strength of the plan 20 Mpa with 4 kinds of mixed variations of 0 %, 0.25 %, 0.5 %, and 0.75 % of the weight of cement used. Compressive and split strength testing of concrete aged 7, 14, and 28 days. The results of slump test results showed that the greater the percentage of Fiberglass the lower the slump produced. The compressive strength test results obtained 0 % at the age of 28 days obtained compressive strength of 20.2 MPa, while the highest addition of fiberglass compressive strength at 28 days the addition of fiberglass by 0.25 % 24.6 MPa. The highest tensile strength at 0.75 % fiber addition was 3.9 MPa, and the maximum flexural strength at 0.75 % fiber addition was 2.889 MPa. From the results of this study it was concluded that with the addition of 0.25 % fiberglass it was found to be strong the highest compressive strength is 24.6 MPa and the splitting strength of 3.9 MPa is produced from the addition of 0.75 % fiber, and the flexural strength of 2.889 MPa is produced from the addition of 0.075 % fiber. with the addition of a certain percentage of fiberglass can add compressive strength, tensile strength and flexural strength in concrete.
