The influence of activator on strength and free linear dilatability and sulfate resistance of chemical waste gypsum - fly ash new road building material as well as action of water reducer are studied.
The experiment showed that the copolymer filtrate reducer is pretty good in depressing the filtration rate, collapse prevention, reservoir protection, thermal stability and resistance salt.
