水泥中混合材对管桩制品强度影响因素分析

Analysis of influence factors of cement admixture on strength of pipe pile products

管桩制品由于其特殊的生产工艺流程,为保证管桩制品的质量要求,对水泥各项性能有严格要求.不同种类的混合材生产的水泥,因其特性不同对管桩制品外观及强度产生较大影响.本文研究结果表明,用于管桩制品的水泥,混合材宜采用能降低水泥需水量的物料,不宜采用火山灰质类和保水性太好的物料.

Pipe pile products need a special production process.In order to ensure the quality of pipe pile products,considering the special production process of pipe pile products,there were strict requirements on the properties of cement.The appearance and strength of pipe pile products were significantly affected by the different properties of cement produced by different kinds of admixture.The results showed that the cement admixture used for pipe pile products should be made of materials that can reduce the water demand of cement,rather than materials with volcanic ash and good water retention.
