Then concrete is made to discuss the relations among curing time, compression strength, elasticity modulus, and thermal conductivity ratio. A series of tests are made to obtain the regression curves as references for engineering and construction. The research results show that, in the granulation sintering mix ratio, cylinder compressive strength limits between 25.09kgf/cm2 and 127.42 kgf/cm2, water absorption falls between 1.57% and 12.84%, loose unit weight limits between 1.19g/m3 and 1.48g/m3, Among them, for M10-TFT64-S20-Na3-NaH3-950 mixture ratio has lowest cost, high cylinder compressive strength , low water absorption ratio, In all concrete mixture ratio, its elasticity modulus, dynamic elasticity modulus, dynamic shear stress modulus, compression stress velocity and shear stress velocity all increase with the growth of the square root of compression strength, Thermal conductivity falls between 0.205 and 0.258, Its thermal conductivity is only half the normal weight concrete, indicating that this kind of green building material is good material.
