This paper has investigated the effects of the six factors of concrete volume density, polystyrene particles, water-cement ratio, sand rate, glass powder, and silicon ash on the thermal properties of polystyrene granular concrete, analyzed the degree of influence of various factors through the principal component method, established a comprehensive index where the thermal conductivity of polystyrene granular concrete, is affected by multiple factors and determined a model equation for the standard value of the thermal conductivity. On this basis, the conclusion has been reached. Specifically, ...
