本实验制作构料的配比为:粉煤灰73％,碱渣10％,石灰17％,采用手工浇铸成型,然后自然养护70～120天。礁块平均强变为38kg/cm~2。实验表明,礁块投放于砂质海底1年后,其外型保持完好;石莼、海带、海胆等附生于表面。投礁前后的水质、沉积物和生物学各项指标均为正常,未发现礁块引起的环境污染。 The experimental production of the ratio of material: fly ash 73%, 10% alkali residue, lime 17%, by hand casting molding, and then the natural conservation of 70 to 120 days. Reef block average strong change 38kg / cm ~ 2. Experiments show that reef block put in sandy seafloor after 1 year, its appearance remains intact; stone 莼, kelp, sea urchins and other attached to the surface. The indexes of water quality, sediment and biology before and after reefing were all normal, and no environmental pollution caused by the reef was found.
