一元有机酸盐化三乙醇胺水泥助磨剂的研究
Triethanolamine Salinized by Monoprotic Organic Acids Cement Grinding Aids
摘要
Abstract
In order to reduce the cost of using triethanolamine and improve its grinding and strengthening effect, DOGA series cement grinding aids were synthesized by salinizing triethanolamine with monobasic organic acid.The effects of DOGA series cement grinding aids on cement properties were studied by analyzing the specific surface area,sieve residue,particle size distribution,TG-DSC and compressive strength of cement hardened paste.The results show that DOGA series cement grinding aids improve the grinding and strengthening effect, a reference sample is made with triethanolamine,and DOGA3 has the best grinding and strengthening effect.When the added amount of DOGA3 is 0.05%, 45 μm sieve residue decreased by 21.1%, specific surface area increased by 21 m2/kg,3-32 μm increased by 2.14%, 3 d and 28 d compressive strength increased by 2.1 MPa and 4.4 MPa, respectively.关键词
