以800℃煅烧2 h得到高活性偏高岭土为原料，水玻璃为碱激发剂，双氧水为发泡剂，通过缩聚反应制备了偏高岭土地聚合物基轻质材料；当双氧水用量为0.25%，60℃固化24 h，水玻璃与偏高岭土用量比为1∶1时，地质聚合物轻质材料的强度最高；水玻璃模数在1.0~2.5范围内，随着水玻璃模数的增大，地质聚合物的体积密度先增大后减小，抗压强度与其体积密度成正相关关系，当水玻璃模数为1.2时，抗压强度为10.13 MPa，体积密度为1.25 g/cm3。

The lightweight geopolymer through polycondensation reaction was synthesized by high reactivity metakaolin which was obtained by the calcination at 800℃ for 2 h as raw material, sodium silicate as alkali excitation agent, hydrogen peroxide as foaming agent. The experimental results show that: when the dosage of hydrogen peroxide was 0.25%, the 60℃ curing 24 h, the sodium silicate and the metakaolin mass ratio was 1∶1, metakaolin geopolymer compressive properties of porous materials was best; the modulus of sodium silicate in the range of 1.0 to 2.5 with the increase of sodium silicate modulus,the volume density of geopolymer ifrst increase, then decrease, the compressive strength and its volume density into positive correlation, the modulus of sodium silicate is 1.2, metakaolin geopolymer compressive intensity of porous materials was 10.13 MPa and volume density was 1.25 g/cm3.
