Reaction Characteristics and Difference of Cinder-Lime and Fly Ash-Lime System
摘要
Abstract
From reaction degree,hydration product,microstructure and compressive strength,reaction process of cinder-lime system was studied under normal temperature and pressure curing and autoclaved curing by contrast with fly ash-lime system that is used widely in industry.FTIR and The mass fractions of active SiO2 and Al2O3 were used to research reaction mechanism.The result show that reaction ability of cinder-lime system is stronger than fly ash-lime system under normal temperature and pressure curing and autoclaved curing,cinder-lime system forms more hydration product and lower n (Ca)/n (Si) C-S-H,it has higher compressive strength.Higher reaction ability of cinder-lime system is due to cinder has lower Si-O stretching vibration wave number about 1100 cm-1 in strong absorption region of IR,more and faster dissolution of SiO2 and Al2O3 reacted with lime,thus cinder-lime system has higher compressive strength than fly ash-lime system under normal temperature and pressure curing and autoclaved curing.关键词
