Abstract

To improve the thermal insulation performance of thermal insulation concrete for mining and save energy, we developed an environmentally friendly thermal insulation concrete with better thermal insulation and performance using a recyclable green organic matter wheat straw fiber. Scanning electron microscopy of the wheat straw fiber revealed that it had a large number of closed microporous structures, which are good heat insulation materials. Different percentages of wheat straw fibers（0%, 2%, 4%, 6%, 8%, 10%） and cement quality were mixed into the thermal insulation mortar, and the thermal conductivity of the thermal insulation concrete gradually decreased. When maintained at 0.201 0-0.200 2 W/（ｍ·Ｋ）, the compressive strength first increased and then decreased, and the maximum compressive strength was 7.14 MPa. Adding 2% of wheat straw fiber can improve the thermal insulation performance and compressive strength. Compared with the heat-insulation concrete without straw fiber, the heat-insulation property and compressive strength are improved, and the heat-insulation property and compressive strength are increased 7.5% and 5.9% respectively.
