In order to reduce heat loss and diffusion of underground heating pipelines, this research incorporated phase change material (PCM) into the controlled low-strength (CLSM) prepare a pipeline backfill with temperature control performance. response problem that PCM leaks easily, new type paraffin–rice husk ash composite (PR-PCM) was obtained by adsorbing melted paraffin rice ash. Through mixing PR-PCM dredged sediment (DS) ordinary Portland cement (OPC), performance prepared. The flowability, mechanical properties, microscopic characteristics, thermal durability CLSM were analyzed through unconfined compressive strength (UCS), X-ray diffraction (XRD), scanning electronic microscopy (SEM), differential calorimetry (DSC), cycle tests. results show when water consumption is constant, as content increases, flowability decreases. has an obvious peak in XRD pattern, its microstructure dense few pores. melting point 50.65 °C latent 4.10 J/g. Compared without PR-PCM, maximum difference during process can reach 3.40 °C, storage improved 4.1%. increases decreases after cycles. containing characteristics control, which plays positive role reducing pipelines areas.
