Special-purpose compound retardant water-reducing agent for sulplo-aluminate and ferro-aluminate cement concrete

Special-purpose compound retardant water-reducing agent for sulplo-aluminate and ferro-aluminate cement concrete

The concrete admixture mainly used in preparation of sulpho-aluminate or ferro-aluminate cement concrete is made of 0-70% of high-effective water-reducing agent with water-reducing rate greater than 12%, 0-50% of general water-reducing agent with water-reducing rate of 5-12%, 1-30% of inorganic or o...

Zusammenfassung:The concrete admixture mainly used in preparation of sulpho-aluminate or ferro-aluminate cement concrete is made of 0-70% of high-effective water-reducing agent with water-reducing rate greater than 12%, 0-50% of general water-reducing agent with water-reducing rate of 5-12%, 1-30% of inorganic or organic weak acid or its salts, 20-60% of admixture carrier and 0-50% of salt. ADVANTAGE-. Can prolong the setting time and workable time of the concrete, improve the workability of the concrete and raise concrete strength and durability.
