Fluorescent concrete with strontium phosphorus powder and plastic waste

Concrete as a structural material can also function in the aesthetic field. The use of fluorescent concrete can beautify buildings, roads and other construction buildings with concrete material. The use of plastic waste has added value to this concrete because it can reduce environmental damage. So that beautiful, environmentally friendly concrete is expected to be created. This research was carried out in the hope of utilising strontium phosphorus powder and plastic waste to increase the value of concrete benefits. The research that will be carried out consists of several stages. First, the problem identification phase and the materials were making up the concrete, so that the characteristics of the material can be known. The second stage is the concrete mix design using SNI 03-2834-2000 guidelines. The third stage is making the compressive strength and concrete panel specimens carried out in the laboratory. The fourth step is testing the compressive strength and concrete panel specimens and analyzing the test results. Concrete test results show that the more the percentage of strontium phosphorus powder instead of cement, the lower the compressive strength of the concrete. For the percentage of concrete plus 4% plastic waste and 5%, strontium phosphorus powder has a compressive strength of 11.69 MPa compared to normal concrete 26.03 MPa. Then the longest time the fluorescent concrete produced by panel concrete plus cement paste 10% strontium phosphorus powder is for 3 hours.
