model jy light thermal insulating pouring material is new irregularly setting fire-resistant material which is made from the excellent and super powerful light aggregate, super minunt material, combine agent and additional agent . this material is series of new fire-resistant lining naterial with low density, high intensity, small thermal conductivity jy系列轻质保温浇注料是一种新型不定型耐火材料,由优质超强轻质骨料、超细粉、结合剂和外加剂组成,是一系列密度低、强度高、导热系数小的新型隔热衬里材料。
in this paper, the effects of fly ash, cement, lime, fine sands, foam agent, w / c ratio and additional agent on foamed concrete were studied by experiments, the best combination ratio of fly ash foamed concrete whose density varies from 551kg / m3 to 650kg / m3 was obtained through orthogonal test design, the foam agent quantity and the fly ash quantity effect the fly ash foamed concrete greatly, so the author selected them as independents to establish duality linear regression equations, the equations were quite ideal through the test of model summary r . moreover, the author also did some experiments about the water resistance of magnesium oxychloride cement fly ash foamed concrete, the outcome showed that phosphoric acid has good effect on water resistance, and its appropriate quantity was found 本文通过试验研究了粉煤灰、水泥、石灰、细砂、发泡液、水灰比及外加剂对粉煤灰发泡混凝土性能的影响,采用正交设计试验方法得出了600级粉煤灰发泡混凝土的最佳配合比,同时发现发泡液和粉煤灰掺量对发泡混凝土的影响最为显著,因此,以二者为自变量建立了二元线性回归方程,通过全相关系数的检验发现方程较为理想。此外,还对氯氧镁水泥基粉煤灰发泡混凝土的耐水性进行了相关实验,发现磷酸有较好的耐水性效果,同时找到了其合适的掺量范围。
