中文摘要：

利用普通硅酸盐水泥为胶凝材料,用少量粉煤灰和矿粉取代部分水泥,按照质量比16：3：1（依次为水泥、粉煤灰、矿粉）、水料比0.5,制备了不同气泡含量的泡沫混凝土。对试样进行单轴压缩破坏试验,得到了不同龄期不同气泡含量的泡沫混凝土破坏应力以及其应力-应变曲线,研究了强度、弹性模量随龄期的变化规律以及与气泡率之间的关系,探讨了泡沫混凝土弹性模量与强度之间的关系。结果表明,泡沫混凝土的抗压强度在一定范围内,受龄期影响较大,而弹性模量受龄期影响较小;抗压强度、弹性模量、屈服应变随气泡率增大而减小;强度和弹性模量与气泡率成指数关系,强度与弹性模量成对数关系。

英文摘要：

According to the mass ratio 16 ： 3 ： 1 （ cement, fly ash, mineral powder, respectively） and the ration of water and material is 0. 5, foam concrete with different content of foam was prepared with ordinary Portland cement and a small amount of fly ash and mineral powder. The uniaxial compression tests for sample were conducted and obtained the failure stress and stress-strain curves of foam concrete with different rate of foam under different curing age. The relationships between compressive strength, elastic modulus and void fraction, the change rules of com- pressive strength and elastic modulus along the curing time were studied. The main results were shown as following： the compressive strength of foam concrete was greatly influenced by curing age, while the elastic modulus was a lit- tle in a certain range. The compressive strength, elastic modulus, yield strain decreases with the increase of void fraction. The strength and elastic modulus are exponential with the void fraction, and the relationships between the strength and the elastic modulus is logarithmic.
