Inclusion of a blend of soda-lime glass powder and sodium hydroxide as an alternative dry activator (DA) powder in fly ash/slag-based one-part alkali-activated materials (AAMs) was investigated. The reactivity of the DA was studied and the properties of DA-based AAMs were compared with both one-part and two-part AAMs activated by solid sodium silicate (NS) and sodium hydroxide/sodium silicate solution (NHNS), respectively. According to results, DA showed reasonable reactivity after heat treatment. DA-based AAMs showed the lowest flowability, but the longest setting time. The strength of NHNS-based AAMs is the highest, followed by DA- and NS-based AAMs. The main reaction product of all types of AAMs is calcium-sodium aluminosilicate hydrate (C-(N)-A-S-H)-type gel. The number of mesopores was greater for both one-part (DA and NS) AAMs than for two-part (NHNS) AAMs. According to cost and emission analyses, DA-based AAMs are cheaper and greener than commercial activator-based AAMs. This study provides a detailed experimental investigation of one-part AAMs activated by an alternative activator to replace the use of commercial alkali silicates.

研究了在粉煤灰/矿渣的单部分碱活化材料（AAMs）中包含钠钙玻璃粉和氢氧化钠的混合物作为替代的干活化剂（DA）粉。研究了DA的反应性，并将基于DA的AAM与分别由固体硅酸钠（NS）和氢氧化钠/硅酸钠溶液（NHNS）活化的单部分和两部分AAM的性能进行了比较。根据结果​​，DA在热处理后显示出合理的反应性。基于DA的AAM流动性最低，但凝固时间最长。基于NHNS的AAM的强度最高，其次是基于DA和NS的AAM。所有类型的AAM的主要反应产物是钙铝硅酸钠水合物（C-（N）-ASH）型凝胶。一部分（DA和NS）AAM的中孔数量均大于两部分（NHNS）AAM的中孔数量。根据成本和排放分析，基于DA的AAM比基于商业活化剂的AAM更便宜，更环保。这项研究提供了由替代活化剂活化的单组分AAM的详细实验研究，以取代商业化碱金属硅酸盐的使用。
