  • Company Name : China Concretes
  • About Us : <br> <br>Detailed introduction to concrete admixture: <br />Main properties <br /> <br />1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sodium sulfate content is loChina Concretesr than 5%, alkali- aggregated reaction can be avoided. <br />2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It has good water reducing and dispersing effect. Water reducing ratio will be 18% (low dosage) to 28% (high dosage). Flow of cement paste and concrete can be enhanced at lower water/cement ratio due to its high water reducing ratio. <br />Workability and flow can be improved greatly at a fixed water/cement ratio, without bleeding and isolating. Meantime, wrapping force between steel bar and concrete is increased. <br />3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Adding 0.5%~1.0% (based on cementing materials) of the product in concrete and keeping the strength of concrete unchangeable, cement dosage can be saved by 20%~30%. <br />4.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When adding 0.5%~1.5% of the product in concrete and keeping cement dosage and concrete slump unchangeable, the compressive strength of concrete can be increased 50%~100% at 1d, 40%~80% at 3d, 25%~70% at 7d, 20%~60% at 28d and 10%~50% at 90d. <br />5.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The product has broad adaptability to cement and other cementing materials. The mechanic properties of concrete can be improved to wide extent. No obvious effect on concrete shrinkage. <br />6.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It can be used to prepare C80 ultra-high strength concrete with slump of 18~20cm or to prepare C60 high strength pumping concrete with slump of 22~25cm. <br />It can be also used to prepare high performance concrete and high carbonization resistant concrete. Used together with air entraining agent, freeze-thawing cycle resistant concrete can be prepared, its freeze-thawing cycle is over 300 times.<br><br>
