Through reading and integrating a large amount of literature, this paper innovatively proposed a new method of making transparent concrete. On this basis, we added fly ash and slag powder to replace cement according to different volume ratios, and developed four new types of green self-compacting transparent concrete with different mix ratios. By testing the compressive strength, tensile strength, elastic modulus and thermal conductivity of these concrete, found that according to (20%, 20%) added fly ash and slag powder cement instead of new green self-dense light transparent concrete in all aspects of the best performance, test results show that the 28 days compressive strength of 36.2 Mpa, 28 days of tensile strength 4 Mpa, 28 days of elastic modulus of 27.1 Gpa. This new type of green self-dense transparent concrete not only has high compressive strength, tensile strength and elastic modulus, but also has excellent transparent thermal conductivity. The experimental results show that the average illumination of four self-dense transparent concrete of 25W bulb is 152XL, and the average illumination of 40W bulb is 246XL and the average temperature is 32.125 ℃. In addition, the photothermal conductivity of the four different mix ratios showed good consistency, indicating that the addition of fly ash and slag powder has no negative impact on the light transmittance of the transparent concrete. This new type of transparent concrete not only has high mechanical properties, but also has good transparent thermal conductivity, which has wide application prospects and provides reference for subsequent research and application.
