The experiment also shows that after the concrete strength reach the frost-resisting critical strength, its strength and elasticity module will increase slowly with the decrease of the temperature.
试验还表明，当混凝土强度达到受冻临界强度后，随着负温值的增大其强度缓慢增长，弹性模量也有缓慢增长。

With W content increasing, the elastic module, flexural strength and fracture toughness increase, but the Vickers 'hardness decreases.
随w含量的增加，复合材料弹性模量、抗弯强度和断裂韧性增大，而硬度减小。

Airport cement concrete pavement structural parameters include slab thickness, concrete bending strength elastic modulus and foundation reaction module.
