摘要
试验研究了煅烧硅藻土对玻化微珠再生混凝土抗压强度、导热系数等性能的影响。结果表明:掺加20%粉煤灰时,玻化微珠再生混凝土的抗压强度随着煅烧硅藻土掺量的增大而提高,且后期强度提高明显,导热系数和密度基本不变,当煅烧硅藻土掺量为3%时,抗压强度达32.93 MPa,导热系数为0.2426 W/(m·K),密度仅为1940.74 kg/m3。
The effects of calcined diatomite on the compressive strength and thermal conductivity of the glazed hollow bead recycled concrete were studied by experiments. Results show that in the case of adding 20 percent fly ash, compressive strength of the glazed hollow beard recycled concrete improves with the increase of the calcined diatomite dosage, and has a significant growth in the late strength,thermal conductivity and density is essentially the same,when calcined diatomite content is 3%,the compressive strength can be achieved 32.93 MPa,thermal conductivity is 0.2426 W/（m·K）,and the density is only 1940.74 kg/m^3.
