Abstract: Using P·II 52.5 grade cement as the cementitious material and steel slag sand as fine aggregate, the steel slag sand with high fluidity and high strength is prepared by adding chemical additives such as water reducer, latex powder and defoamer Special mortar, and the effects of two differe
READ MOREAbstract: The process and product performance of carboxymethyl cellulose cross-linked by N, N-methylenebisacrylamide to prepare superabsorbent resin were studied, and the concentration of alkali, the amount of cross-linking agent, alkali etherification, and solvent were discussed. The effect of dosa
READ MOREAbstract: By measuring the mechanical properties, water retention rate, setting time and heat of hydration of cellulose ether with different viscosities in different dosages of cement paste, and using SEM to analyze the hydration products, the effect of cellulose ether on the performance of cement p
READ MOREAbstract: The influence of the amount of cellulose ether, relative molecular mass and modification method on the water-absorbing and whitening phenomenon of real stone paint is discussed, and the cellulose ether with the best water-whitening resistance of real stone paint is screened out, and the co
READ MOREAbstract: The modified cement mortar with a water-cement ratio of 0.45, a lime-sand ratio of 1:2.5, and cellulose ether with different viscosities of 0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1.0% was prepared. By measuring the mechanical properties of cement mortar and observing the microscopic morphology, t
READ MOREAbstract: Using straw cellulose as raw material, it was modified by etherification. Through the single factor and rotation test, the optimal conditions for the preparation of carboxymethyl cellulose were determined to be: etherification time 100min, etherification temperature 70℃, NaOH dosage 3.2g a
