Effect of Sulfonated Acetone Formaldehyde (SAF) on the Firing Resistance and Aggressive Attach of SRC-SF Composite Cement Pastes | Science Publications

摘要

> >Thiswork aimed to study the effect of the dosage of laboratory synthesizedSulfonated Acetone Formaldehyde (SAF) on the physic-mechanical characteristicsand durability of SF-SRC cement pastes immersed in 4% MgCl₂ or 4%MgSO₄ solutions or at elevated temperatures up to 800°C. The compressive strength of thermallytreatment cement pastes with 1.5% SAF increases up to 600°C, then decreases up to 800°C. Presence of 2.0% SAF works to produce acompact cementing structure, which decreases the accessibility of thepenetration of chloride as well as sulphate ion penetration and enhances thedurability, hence the total chloride and sulphate contents diminished.
