Study on the Properties of Sea Sand Concrete with Fly Ash

Abstract:

The harmful chloride ion in sea sand concrete is the main issue that hinders its application, proposing a method using fly ash the active mineral, chloride ion content of harmful curing of sea sand concrete, to improve the durability of sea sand concrete. The experiment studies the influence of sand in the chlorine ion and fly ash on the strength of concrete, and analyzes microscopic structure and hydration products of concrete. Research results show that: the sea sand concrete with 20% fly ash prepared has good mechanical properties and durability; the existence of Cl- on the early strength of sea sand concrete has a positive promoting role, but has negative effective on the later development.
