Long term properties of cement-based material incorporated with

The energy-saving concrete was developed by incorporating n-octadecane and diatomite composite shape-stabilized phase change materials (OC/D SSPCMs) into cement concrete. OC/D SSPCMs were prepared by vacuum impregnation of barrel diatomite. The results show that the melting point and enthalpy of OC/...

OC/D SSPCMs were prepared by vacuum impregnation of barrel diatomite. The results show that the melting point and enthalpy of OC/D SSPCMs are 25.02 °C and 60.26 J/g, and OC/D SSPCMs have good dispersion and compatibility in cement paste. As a structure-function integrated material, energy-saving concrete with compressive strength of 33.5 MPa has a broad application prospect. Self-designed room test results reveal that energy-saving concrete can reduce the indoor temperature by 4.5 °C. Long-term thermal/mechanical properties, volume deformation and microstructure after thermal cycling treatment were investigated. The results indicate that phase transformation behavior has a huge negative effect on the compressive strength and deformation tendency of energy-saving concrete, being mainly attributed to the significant volume evolution with the temperature of PCM and PCM encapsulation leakage.

Long-term thermal/mechanical properties, volume deformation and microstructure after thermal cycling treatment were investigated. The results indicate that phase transformation behavior has a huge negative effect on the compressive strength and deformation tendency of energy-saving concrete, being mainly attributed to the significant volume evolution with the temperature of PCM and PCM encapsulation leakage.

OC/D SSPCMs were prepared by vacuum impregnation of barrel diatomite. The results show that the melting point and enthalpy of OC/D SSPCMs are 25.02 °C and 60.26 J/g, and OC/D SSPCMs have good dispersion and compatibility in cement paste. As a structure-function integrated material, energy-saving concrete with compressive strength of 33.5 MPa has a broad application prospect. Self-designed room test results reveal that energy-saving concrete can reduce the indoor temperature by 4.5 °C. Long-term thermal/mechanical properties, volume deformation and microstructure after thermal cycling treatment were investigated. The results indicate that phase transformation behavior has a huge negative effect on the compressive strength and deformation tendency of energy-saving concrete, being mainly attributed to the significant volume evolution with the temperature of PCM and PCM encapsulation leakage.

abstract	The energy-saving concrete was developed by incorporating n-octadecane and diatomite composite shape-stabilized phase change materials (OC/D SSPCMs) into cement concrete. OC/D SSPCMs were prepared by vacuum impregnation of barrel diatomite. The results show that the melting point and enthalpy of OC/D SSPCMs are 25.02 °C and 60.26 J/g, and OC/D SSPCMs have good dispersion and compatibility in cement paste. As a structure-function integrated material, energy-saving concrete with compressive strength of 33.5 MPa has a broad application prospect. Self-designed room test results reveal that energy-saving concrete can reduce the indoor temperature by 4.5 °C. Long-term thermal/mechanical properties, volume deformation and microstructure after thermal cycling treatment were investigated. The results indicate that phase transformation behavior has a huge negative effect on the compressive strength and deformation tendency of energy-saving concrete, being mainly attributed to the significant volume evolution with the temperature of PCM and PCM encapsulation leakage.
