Evaluation and high temperature strengthening mechanism of alkali activated biological-ash hybrid glass fiber-carbon fiber cement slurry system

In recent years, with the rapid development of biomass combustion power generation and heat as main application industry, amount byproduct biological ash is also increasing year by year. How to effectively utilize in a more green, environmental friendly economic way has become research hotspot. view problem that mechanical properties cement stone decreased when conventional latex was used toughening agent, based on introduction high dispersive composite modified fiber enhance toughness stone, this paper analyzed physical chemical status ash, further explored influence role admixture high-temperature Mechanism. The results show dosage range 0–10% (wt%), it little effect basic slurry certain preventive gas channeling stone. analysis comprehensive properties, activated can compactness matrix under temperature reducing Ca/Si ratio through secondary pozzolanic effect, stimulate formation large number hydration products, strengthen later strength growth rate cement. resistance paste be improved hybrid dispersion fiber.
