Abstract

In this study, the effects of metakaolin content on workability and mechanical properties of fly ash based inorganic polymeric materials are investigated. Raw materials used include fly ash (FA), metakaolin (Meta), sodium hydroxide (NaOH), silica fume (SF), water and sand. FAM is defined as the total weight of FA and Meta. The ratios of Meta/FA investigated are 0%, 10%, 20% and 30%; NaOH/FAM are 0%, 5%, 7.5%, and 10%; and SF/FAM are 0%, 5%, 7.5%, and 10%. The slump and demold age of each batch are measured, also the compressive strength of prism specimens at ages of 1 day, 7 days and 28 days. Possible effects of various compositions on workability and compressive strength will be discussed in this paper, and attention will be given to the mechanism of the added Al-rich constituent in the polymerization reaction of fly ash based inorganic polymeric materials.

粉煤灰基无机高分子材料的配合比研究

研究了偏高岭土含量对粉煤灰基无机高分子材料和易性和力学性能的影响。使用的原料包括粉煤灰(FA)、偏高岭土(Meta)、氢氧化钠(NaOH)、硅灰(SF)、水和沙子。FAM定义为FA和Meta的总权重。Meta/FA的调查比例分别为0%、10%、20%和30%;NaOH/FAM分别为0%、5%、7.5%和10%;SF/FAM分别为0%、5%、7.5%、10%。测定了每批棱柱试件在1天、7天、28天龄期的坍落度、脱模龄期及抗压强度。本文讨论了不同组分对粉煤灰基无机高分子材料的和易性和抗压强度可能产生的影响，并重点讨论了添加富铝组分在粉煤灰基无机高分子材料聚合反应中的作用机理。
